Life History Consequences of the Facultative Expression of a Dispersal Life Stage in the Phoretic Bulb Mite (Rhizoglyphus robini).

Life History Consequences of the Facultative Expression of a Dispersal Life Stage in the Phoretic Bulb Mite (Rhizoglyphus robini).

Initial dataset (individuals isolated as eggs). A total of 27 females were isolated from the stock cultures over three consecutive, replicate time periods: 15 in the first period, 6 in the sec- ond and 6 in the third. These females were allowed to lay eggs for 3–8 days. A total of 132 eggs were collected over the three replicates time periods: replicate one, 51 eggs collected over 7 days; replicate two, 54 eggs collected over 8 days; and replicate three, 27 eggs collected over 3 days. Eggs were collected daily from each female, and individually isolated into single tubes with ad libitum oats. The tubes were kept in an unlit incubator at 24°C and >70% relative humidity. Until maturation, each individual was photographed daily using a Lumenera Infinity 3.1 camera (Lumenera Corporation, Ottawa, 22 Ontario, Canada) connected to a Meiji 20 EMZ-8TRD (10–45x) stereomicroscope and its length (without mouthparts) measured to the nearest 0.001 mm using Infinity Analyze Imaging Software (Lumenera Corp.). Henceforth body length is referred to as size. Some individuals died before reaching maturity (replicate time period 1, n = 25; replicate time period 2, n = 33; replicate time period 3, n = 14), and of the 132 eggs only 3 subsequently developed into deutonymphs. Mature females were mated with randomly chosen virgin males (from either morph), which were placed in the same tube for the duration of the female’s lifetime. Eggs were counted daily until the female died.

Dynamic Model for Life History of Scyphozoa.

Dynamic Model for Life History of Scyphozoa.

A two-state life history model governed by ODEs is formulated to elucidate the population dynamics of jellyfish and to illuminate the triggering mechanism of its blooms. The polyp- medusa model admits trichotomous global dynamic scenarios: extinction, polyps survival only, and both survival. The population dynamics sensitively depend on several biotic and abiotic limiting factors such as substrate, temperature, and predation. The combination of temperature increase, substrate expansion, and predator diminishment acts synergistically to create a habitat that is more favorable for jellyfishes. Reducing artificial marine construc- tions, aiding predator populations, and directly controlling the jellyfish population would help to manage the jellyfish blooms. The theoretical analyses and numerical experiments yield several insights into the nature underlying the model and shed some new light on the gener- al control strategy for jellyfish.

Life-history trait database of European reptile species

Life-history trait database of European reptile species

the most comprehensive one. We therefore largely followed them but evaluated several more recent name changes by using original publications. We agree with Speybroeck et al. (2010) that the scientiic name of a species should only be changed if there is strong evidence of it being necessary to relect evolutionary history and if data are supported by sound evidence. On the other hand, further taxon splitting is a necessary conse- quence of advances in systematics. Strong evidence for us means that a name change is backed by suiciently comprehensive sampling, by consistent evidence from more than one character set analysed with appropriate statistical methods, and by sound bio- geographic scenarios. For inclusion in the database, an additional criterion had to be fulilled: the distribution of the taxa involved must have been worked out suiciently to allow allocation of life-history data to a particular taxon without uncertainty. his resulted in 144 recognized species belonging to 59 genera (named current taxonomy in the database; Suppl. material 1: Table S1). Deviations from Speybroeck et al. (2010) and Sillero et al. (2014) are listed and justiied in Suppl. material 2: Table S2. he da- tabase is designed in such a way that taxa (European or non-European) can be added without a need to change the structure of the database. he database can be searched using both the original names as in Gasc et al. (2004) as well as the updated names. We allocated data that were published before species complexes were split to the relevant new taxa if this allocation could be made with certainty.

The Mass-Longevity Triangle: Pareto Optimality and the Geometry of Life-History Trait Space.

The Mass-Longevity Triangle: Pareto Optimality and the Geometry of Life-History Trait Space.

When organisms need to perform multiple tasks they face a fundamental tradeoff: no phe- notype can be optimal at all tasks. This situation was recently analyzed using Pareto opti- mality, showing that tradeoffs between tasks lead to phenotypes distributed on low dimensional polygons in trait space. The vertices of these polygons are archetypes—phe- notypes optimal at a single task. This theory was applied to examples from animal morphol- ogy and gene expression. Here we ask whether Pareto optimality theory can apply to life history traits, which include longevity, fecundity and mass. To comprehensively explore the geometry of life history trait space, we analyze a dataset of life history traits of 2105 endo- thermic species. We find that, to a first approximation, life history traits fall on a triangle in log-mass log-longevity space. The vertices of the triangle suggest three archetypal strate- gies, exemplified by bats, shrews and whales, with specialists near the vertices and gener- alists in the middle of the triangle. To a second approximation, the data lies in a tetrahedron, whose extra vertex above the mass-longevity triangle suggests a fourth strategy related to carnivory. Each animal species can thus be placed in a coordinate system according to its distance from the archetypes, which may be useful for genome-scale comparative studies of mammalian aging and other biological aspects. We further demonstrate that Pareto opti- mality can explain a range of previous studies which found animal and plant phenotypes which lie in triangles in trait space. This study demonstrates the applicability of multi-objec- tive optimization principles to understand life history traits and to infer archetypal strategies that suggest why some mammalian species live much longer than others of similar mass.

The Effect of Isolation on the Life-history Traits of Pseudosuccinea columella (Pulmonata: Lymnaeidae)

The Effect of Isolation on the Life-history Traits of Pseudosuccinea columella (Pulmonata: Lymnaeidae)

All snails raised in pairs lasted longer than seven weeks (the first snail died during week 8). Besides, in only three pairs one of the partners died before the other previous to week 20, all other snails ei- ther survived until week 22 (after which no repro- duction was observed) or both partners died in the same week. The fact that the death of a partner might affect the mating system is accepted, how- ever we do not consider that it significantly affected the life-history traits of the group since all deaths occurred when snails were either not reproducing at all or (in fewer cases) laying few eggs. There- fore, calculations still hold significant since all paired snails grew up actually in pairs pass their reproductive peak and just a few of them lost their partners when contribution to the population growth was not significant (Fig. 1C)

This qualitative study aimed to get to know the relationship between the experiences of families of children with a life-threatening disease and their religion, illness and life histories. The methodological framework was based on Oral History. The data were collected through interviews and the participants were nine families from six different religions who had lived the experience of having a child with a life-threatening disease. The interviews, held with one or two family members, were transcribed, textualized and, through their analysis, the Vital Tone was elaborated, representing the moral synthesis of each narrative. Three dimensions of spirituality were related to illness and death in their life histories: a Higher Being with a healing power; Development and Maintenance of a Connection with God and Faith Encouraging Optimism. The narratives demonstrated the family’s search to attribute meanings to their experiences, based on their religious beliefs.

Life History Strategy and the HEXACO Personality Dimensions

Life History Strategy and the HEXACO Personality Dimensions

From these principles, proponents of LHS-based personality theory have formulated the following arguments. First, a slow LHS will be associated with longer-term planning (less future discounting—e.g., Wilson and Daly, 1997) than a fast LHS (Figueredo et al., 2006). Because humans are “ultrasocial” and dependent on culturally transmitted knowledge (Hill, Barton, and Hurtado, 2009), and because the reproductive payoffs to cooperative social relationships are often delayed over multi-year periods (e.g., Gurven, Allen-Arave, Hill, and Hurtado, 2000), a slow LHS in H. sapiens is expected to be associated with personality traits that prioritize sociality, altruism (both kin-selected and reciprocal), and adherence to social norms (Rushton, 1985). Individuals pursuing a slow LHS are expected to form stable, long-term mating relationships. Higher investment in somatic effort should lead to improved psychological health, including greater positive emotionality, less negative emotionality, and greater capacity for, and enjoyment of, intellectual effort. In contrast, a fast LHS will be associated with a focus on short-term gains (including short-term mating strategies), an antagonistic social orientation, and poorer physical and psychological health.

Ecology and life history of an Amazon floodplain cichlid: the discus fish

Ecology and life history of an Amazon floodplain cichlid: the discus fish

Group living and parasites. Group living, even if temporary, has disadvantages - notably the increased transmission of dis- eases and parasites (Trivers, 1985). A large proportion (14%) of discus from the Uxi Bay was infested with the isopod B. cichlae. This parasite not only appears to retard discus growth, but appears also to limit the development of bright colors (see ‘color’ in Results). Braga cichlae devours gill lamellae, causing reduced oxygen uptake and presumably therefore hindering normal growth and development. In a separate paper, data will be presented to show that discus are infested far more frequently by B. cichlae than other syntopic cichlids, despite the generalist nature of this parasite (Thatcher, 1991); this lack of host specificity can be demonstrated by provid- ing free-swimming B. cichlae with a choice of Symphysodon versus other cichlid hosts. Because discus develop bright color as a secondary sexual ornament (see ‘color’ in Results), and because parasites both diminish color and stunt growth, a case will be made for bright color serving as an index of parasite load in mate choice. There is a strong theoretical basis for color serving as an index of mate quality, includ- ing general health and parasite load (e.g. Maynard-Smith & Harper, 2003). As such, there may be a parasite-mediated link between the formation of extremely large aggregations, and the possession of bright color extending over much of the body surface - both features unique to Symphysodon among South American cichlids.

ABSTRACT - Background - Heartburn and regurgitation frequently occur in the third trimester of pregnancy, but their impact on quality of life has not been thoroughly investigated. Objective - To measure health-related quality of life of third-trimester pregnant women with heartburn and regurgitation. Methods - Data on obstetric history, heartburn and regurgitation frequency and intensi- ty, history of heartburn and regurgitation and health-related quality of life were collected of 82 third-trimester pregnant women. Results - Sixty-two (76%) women had heartburn, and 58 (71%), regurgitation; 20 were asymptomatic. Mean gestational age was 33.8±3.7 weeks; 35 (43%) women had a family history of heartburn and/or regurgitation, and 57 (70%) were asymptomatic before pregnancy. The following quality of life concepts were signiicantly reduced: physical problems and social functioning for heartburn; physical problems and emotional functioning for regurgitation. There was agreement between heartburn in present and previous pregnancies. Conclusion - Heartburn and/or regurgitation affected health-related quality of life of third trimester pregnant women. HEADINGS - Heartburn. Gastroesophageal relux. Pregnancy. Quality of life.

Contribution To The Study Of Reproduction Parameters Of The European Conger Eel Conger Conger Linnaeus 1758 From The Western Algerian Coasts Oran Bay Algeria

Contribution To The Study Of Reproduction Parameters Of The European Conger Eel Conger Conger Linnaeus 1758 From The Western Algerian Coasts Oran Bay Algeria

The European conger eel, Conger conger L. (Osteichthyes, Congridae) is a benthic specie living in rocky and sandy bottoms between 10 and 1000 m (Culurgioni et al., 2006). It is widely distributed in the Eastern Atlantic, in the Western Black Sea and it is very common in all the Mediterranean Sea (Relini et al., 1999). The specie constitutes an important commercial and recreational fishery resource that is caught by bottom trawl, hook and line (Figueiredo et al. 1996). Despite being a geographically widespread species and an important fisheries resource, little is presently known about the life history traits of this species, namely its reproductive biology, spawning area(s) and migratory patterns (Correia et al. 2012). In the Western Mediterranean Sea of Algeria, it is the most exploited Congridea. Mazouz et al. (2014) and Abi-Ayad et al (2011) described the histological oogenesis and spermatogenesis respectively of the C.conger from the Western Algerian coasts. However, no studies on growth and reproduction parameters of this important benthic species from South shore of Mediterranean Sea have been published (Mazouz et al. 2014., Abi-Ayad et al. 2011). In this paper, we provide the first

Earth history and evolution of life in curriculum the high school of the State of São Paulo

Obviously, the complexity of integrating strate- gies should not be an obstacle to their own adop- tion, but an invitation to change the traditional way of teaching, mediated by the teacher. For such, it is necessary that teacher trainings incorporate the interdisciplinar approach, facilitating to teachers the understanding of processes that occur in the evolution of life and historical transformation of terrestrial environments. What we propose is not different from what is acknowledged as important in official documents. However, it requires the exiting of the “comfort zone” of such approaches based on strict scholarly disciplines. It also requires that teachers start to acknowledge and be aware of the teaching resources they have at their disposal, in order to provide knowledge contextualized with the student’s reality. For Morin (2005) there is not a guide but a challenge, which incorporates a “motivation to think”, reflect and approach the complexity from an interdisciplinary treatment of the contents of Nature Science.

Life History Strategy and Disordered Eating Behavior

Life History Strategy and Disordered Eating Behavior

By analogy, individuals with disordered eating behaviors might be unable to eat in moderation due to insufficient competencies in behavioral regulation, as in the cyclical binging of bulimics, who rely on purging afterwards to control their weight. Anorexics instead restrict their food intake to unhealthy and even life-threatening levels, possibly as a paradoxical overreaction to tendencies towards overeating. These adverse health consequences may be seen as unintended side-effects of these alternative weight-control strategies in girls who perceive themselves to be under high degrees of competitive pressure from other girls. Although the reproductive suppression hypothesis considers amenorrhea and infertility as the ultimate function of anorexic behavior, the present results indicate that they might also represent unintended and fitness-reducing consequences of disordered eating behavior. The present results indirectly associate disordered eating behaviors with faster life history strategies, instead of the slower ones that might be expected to correlate with adaptive reproductive suppression. The present results are therefore inconsistent with the reproductive suppression hypothesis, because sacrificing present reproduction in favor of potential future reproduction is a tactic more aligned with slow life history strategy (Ellis, Figueredo, Brumbach, and Schlomer, 2009).

HISTÓRIA DE VIDA DOS SERVIDORES NA CONSTRUÇÃO DA MEMÓRIA DA INSTITUIÇÃO :: Brapci ::

Abstract: The study covers the history of the Publisher UFPB from individual memories of your servers and former employees who witnessed a trajectory marked by a large and significant number of didactic, literary and scientific publications, as well as its introduction, appreciation and failure. Methodologically, the research was based on the qualitative approach of documentary type associated with oral history from the perspective of thematic oral history and life of older servers of the publisher, some of which are in full activity. It is understood by one set of memory events, facts, characters that, through their existence in the past, have consistent experiences to establish a relationship of today and their past, either immediately or remote. This relationship is always mediated by the experience. The narratives reveal the subjects' ears wide history of an institution allowing emerge emotionality of servers that witnessed a promising structure and experienced a decline in successive administrations of the university.

	Field Cancerisation of the Upper Aerodigestive Tract: Screening for Second Primary Cancers of the Oesophagus in Cancer Survivors

Field Cancerisation of the Upper Aerodigestive Tract: Screening for Second Primary Cancers of the Oesophagus in Cancer Survivors

Tobacco, alcohol, and betel quid are the main causes of squamous cell cancers of the upper aerodigestive tract. These substances can cause multifocal carcinogenesis leading to multiple synchronous or metachronous cancers of the oesophagus, head and neck region, and lungs (‘ield cancerisation’). Globally there are several million people who have survived either head and neck squamous cell cancer (HNSCC) or lung cancer (LC). HNSCC and LC survivors are at increased risk of developing second primary malignancies, including second primary cancers of the oesophagus. The risk of second primary oesophageal squamous cell cancer (OSCC) ranges from 8-30% in HNSCC patients. LC and HNSCC survivors should be ofered endoscopic surveillance of the oesophagus. Lugol chromoendoscopy is the traditional and best evaluated screening method to detect early squamous cell neoplasias of the oesophagus. More recently, narrow band imaging combined with magnifying endoscopy has been established as an alternative screening method in Asia. Low-dose chest computed tomography (CT) is the best evidence- based screening technique to detect (second primary) LC and to reduce LC-related mortality. Low-dose chest CT screening is therefore recommended in OSCC, HNSCC, and LC survivors. In addition, OSCC survivors should undergo periodic pharyngolaryngoscopy for early detection of second primary HNSCC. Secondary prevention aims at quitting smoking, betel quid chewing, and alcohol consumption. As ield cancerisation involves the oesophagus, the bronchi, and the head and neck region, the patients at risk are best surveilled and managed by an interdisciplinary team.

conceptual tools and research sources, thus expanding historiography at a “vertiginous rate”, as said by Burke (1992, p.8; see also Le Goff, Nora, 1976a, 1976b e 1976c). Concomitantly, the domain set by Rosen was flooded with numerous monographs and articles by and large produced by historians with no medical background and aligned with the trends in historiography and in the social sciences. Elizabeth Fee (1993; Fee, Morman, 1993) points out the ideological cleavages between the generation of historians modelled by the 1960s contestation movements and of historian- physicians belonging to Rosen’s generation, who were illuministically optimists as far as the progress of science and the capacity of the medical establishment to solve humanity’s health problems, as long as they used the stored knowledge on behalf of a preventive and social medicine. The new generations of historians critically studied the control mechanisms implicit in medical discourse and institutions, were interested in the knowledge and practices that were alternatives to academic medicine or that came from territories subjugated to colonial empires as well as to capitals in the Third World. The critique to euro-centrism was translated into a renewed interest in the history of medical systems that did not originate from the Greek-Roman matrix or did not follow European medicine. Race and gender issues, a more refined approach to social classes and categories, the attention paid to actors and local particularities came to inform the studies on health politics, institutions and professions. The history of medicine was no longer the history of physicians only to also become the history of patients, and the history of diseases had its real boom of monographic studies. The body, childhood, the sensibilities, the environment and other issues attenuated the frontiers between the science of history and other human and natural sciences.

The influence of the arc plasma treatment on the structure and microhardness C120U carbon tool steel

The influence of the arc plasma treatment on the structure and microhardness C120U carbon tool steel

Surface of C120 steel after arc plasma treatment showed tracks have multizone microstructure composed of the remelted zone, heat affected zone and substrate, which can have diversified microhardness. Structure (particularly precipitation of martensite, bainite retained austenite and secondary cementite) in the remelted zone is dependent on the arc plasma treatment parameters. The cooling rate obtained during the treatment by arc plasma of the steels is compared to the cooling rate of the steels during conventional heat treatment. This cooling rate can be estimated on the basis of the standard CCT diagram for C120 steel. Increased of the current intensity of arc plasma lead to of grater areas of materials remelting and it decreases of the cooling

The Existence Of Leading Islands Securing And The Border Areas Unitary State Of Indonesia An Analysis In Law Perspective

While the political aspect, the border region is classified as vulnerable to political conflicts with neighboring countries due to the intersection of territorial and jurisdictional boundaries, especially in the segment of border that have not been agreed. The issue of border actually starts to rise along with the emergence of waters and fisheries department in 2000 as it continued to release the border policy through the Decree of President (Perpres) No. 78 of 2005 concern the Management of the Outermost Small Islands. As we know there are 11 (eleven) cases in both borders sea and land, as follow: First, the case of Sipadan and Ligitan islands (two our leading islands) by the International Court has decided to belong to Malaysia since 2002. Secondly, the case of Ambalat as an effort of Malaysia to claim the waters territory called Ambalat block occur vagueness in maritime boundary so that this neighboring country tries to take advantage of this vagueness and at last Indonesia set a new base point from Karang Ungaran, until now negotiation has not been completed. Third, Jemur island in Riau province were ever claimed by Malaysia but actually the island is behind our leading island in the area. Fourth, the hostage of supervisory personnel of marine and fishery resources of our borders by Malaysia in response to the arrest of Malaysian fishermen that entering Indonesian waters illegally. These facts indicate that almost each year occur borderline cases experienced by Indonesia. Certainly, it has been a restriction on the importance of the Indonesia sovereignty as a maritime country to be developed and considered as one of the forms of the sovereignty of the Republic of Indonesia relating to the international sea, archipelagic and deepness waters as well as the air space over the territorial sea, archipelagic waters and inland as well seabed and land including natural resources contained therein. Given the importance of maritime areas handling related to the waters, islands and fisheries, it is necessary for specially the management of area with regard to the coastal areas and small islands which are also regulated in Act No. 1 of 2014 concern the Amendment of Act No. 27 of 2007 concern the Management of Coastal Areas and Small Islands. In the Act is understood that the coastal areas and small islands are vulnerable damaged by the activities of people in the use of resources or due to natural disasters and exploitation, so that the need for security measures in the area.

Statistical Assessment of the Effect of Chemical Composition on Mechanical Properties of Hypereutectic AlSi17CuNiMg Silumin

Statistical Assessment of the Effect of Chemical Composition on Mechanical Properties of Hypereutectic AlSi17CuNiMg Silumin

The above mentioned alloys were fabricated from the following starting materials (Table 1): aluminium in grade AR1 (99,96% Al), silicon of 98,5% purity (rest Fe and other elements), copper (99, 98% Cu), nickel (99, 98% Ni) and cast AG10 alloy (about 10 wt.% Mg). Melts were conducted in a Leybold-Heraeus IS5/III induction furnace with crucible of 0,7kg capacity made from magnesite refractory material. A protective coating of 2NaF and KCl was used. When the furnace temperature of ~ 820 o C had been reached, the melt was subjected to refining treatment with Rafglin-3 in an amount of 0,3 wt.%, followed by modification with Cu-P (~9,95%P). The temperature of pouring was controlled by a NiCr-NiAl TP-202K-800-1 thermocouple immersed in the bath of molten metal.
