Abstract:
In this study, we consider the applicability of Bergmann’s rule to the populations of small pelagic fish species in the Mediterranean Sea. Under Bergmann’s rule, body size increases with decreasing temperature and increasing latitude. Although this macroecological pattern in body sizes is well established for many taxa of endotherms and ectotherms, it remains not universal and the proposed mechanisms underlying it are multiple and still lack consensus. We explored here the occurrence of geographical body size clines using measurements of average body sizes of 10 species collected in pelagic tr

Abstract:
Abstract Ecogeographical rules predict an association between specific adaptive morphological/physiological traits and latitude, elevation or cooler climates. Such ecogeographical effects are often expressed most clearly in widely distributed species due to continuous selective adaptation occurring over their geographic range. Based on 40 population sampling sites of 116 adult individuals (female, ; male, ) across an elevational range of 191–2573 m, we tested whether morphological traits accorded with predictions of Bergmann’s rule, Allen’s rule and Hesse’s rule for the South China field mouse

Abstract:
According to Bergmann’s Rule, individuals who inhabit higher altitudes tend to be larger in body mass or size, when compared with individuals of the same taxon who inhabit lower altitude places. Black flies are insects of great medical and veterinary importance due to its blood-sucking habit, becoming subject of studies regarding its bionomics, ecology and taxonomy. Studies approaching the influence of the altitude gradient in the morphology of Diptera: Simuliidae larvae are scarce in the literature, therefore, this study aimed to investigate the influence of altitude gradient in the morpholog

Abstract:
The relationship between body size and latitude has been the focus of dozens of studies across many species. However, results of testing Bergmann’s rule — that organisms in colder climates or at higher latitudes possess larger body sizes — have been inconsistent across studies. We investigated whether snowshoe hares (Lepus americanus Erxleben, 1777) follow Bergmann’s rule by investigating differences in body mass using data from six published studies and from data of 755 individual hares captured from 10 populations across North America covering 26° of north latitude.

Abstract:
Body size varies according to nutritional availability, which is of ecological and evolutionary relevance. The purpose of this study is to test the hypothesis that differences in adult body size are realized by increasing juvenile growth rate for white-tailed deer (Odocoileus virginianus). Harvest records are used to construct growth rate estimates by empirical nonlinear curve fitting. Results are compared to those of previous models that include additional parameters. The rate of growth increases during the study period. Models that estimate multiple parameters may not work with harvest data

Abstract:
Bergmann’s and Allen’s rule suggest that for the same species individuals found further north, tend to have larger body sizes and smaller appendages compared to individuals further south, respectively, due to constraints for thermal regulation. This has shown especially true for birds and mammals.  In this paper, I test to see if global warming has led to a change in morphology for birds, i.e. body weight and wing size. We use year as a proxy for temperature as global warming has on average lead to an increase in the earth’s surface temperature over the last century with most of the change occ

Abstract:
Behavior determines how organisms interact with their environment, and has long been posited as a pacemaker for evolution. The classical view is that novel behaviors expose organisms to new selective pressures, in turn "driving" evolution. Behavior can also restrain evolutionary change. Some behaviors, such as thermoregulation, help organisms maintain a constant selective environment, thus "inhibiting" evolution. This thesis seeks to understand the role of behavior in influencing the evolutionary process. In the first part, I test the hypothesis that the same behavior can simultaneously imped

The classic model of body size evolution (Bergmann's Rule) holds that body size is driven by temperature, but more recent hypotheses have suggested that other climatic variables or biotic interactions may play a more important role. The use of paleoecological data to address this question allows variables that are tightly correlated in modern ecosystems to be teased apart and allows body size patterns to be

Abstract:
Growth involves two flows of energy. The first is chemical potential energy in the monomers used to construct the proteins, lipids, polysaccharides and nucleic acids forming the new tissue. The second is the metabolic energy (ATP or GTP) used to construct the new tissue; this is the metabolic cost of growth and can be expressed as a dimensionless fraction of the energy retained in the new tissue. Its value is ~0.33. Typical temperature sensitivities for growth in the wild lie in the range Q10 1.5 – 3. Within species there may be evolutionary adjustments to growth rate to offset the effects of

Abstract:
This chapter concludes with the major theme that ran through the previous chapters; how much of each of these skeletal activity reconstruction features are a result of environmental influences (i.e., activities) and how much of the variation in these features are a result of genes. Biological confounds, which are largely genetic, have been found in all of the skeletal features covered in the previous chapters. For example, evolutionary body type rules (i.e., Bergmann’s and Allen’s Rules) affect measures of cross-sectional geometries. Plus, age is known to increase entheseal change scores. Furthermore, twin studies have revealed hereditary etiologies for osteoarthritis and Schmorl’s nodes. Yet, not all of the variance is genetic and, thus, the question remains whether skeletal indicators of activity can still be used to reconstruct activity patterns. Methods that avoid circular reasoning and aim to use only skeletal features with predictive validity should be the ultimate goal for those studying skeletal remains. If skeletal indicators of activity cannot be used to reconstruct what people did in the past, then perhaps these skeletal features can help in other ways, such as improving age estimates or drawing better conclusions about biological relatedness.
