Biometry data to reveal geographic variation in Bramblings Fringilla montifringilla

Abstract The Brambling Fringilla montifringilla has a large breeding distribution across the entire Palaearctic taiga region. Birds in the Far East are more brightly coloured and formerly separated as subspecies subcuneolata (S. Cramp & C. M. Perrins 1994; Handbook of the Birds of Europe, the Middle East and North Africa. The Birds of the Western Palearctic, Vol. 8. Oxford University Press, Oxford). To reveal possible geographical variation in the size of the wing, primary feathers, bill, and in the extent of the partial post-juvenile moult, we present measurements taken from 579 skins of the Natural History Museum, Tring UK, Natural History Museum of Denmark, Copenhagen, The Arctic University Museum of Norway, Tromsø, Natural History Museum, University of Oslo, Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Swedish Museum of Natural History, Stockholm, and Finnish  Museum of Natural History, Helsinki. I thank I. C. J. Galbraith for allowing us to measure the birds in the collection of the Natural History Museum, Tring UK, and the following museums and their curators for sending Brambling specimens to Switzerland more than 35 years ago: Natural History Museum of Denmark, Copenhagen (Jon Fieldså), The Arctic University Museum of Norway, Tromsø (Hans-Petter Mannvik and Wim Vader), Natural History Museum, University of Oslo (Tore Slagsvold), Zoologisches Forschungsmuseum Alexander Koenig, Bonn (Renate van den Elzen), Swedish Museum of Natural History, Stockholm (Bo Fernholm), and Finnish  Museum of Natural History, Helsinki (Ann Forstén).

Geographic patterns in morphometric and genetic variation for coyote populations with emphasis on southeastern coyotes

Prior to 1900, coyotes (Canis latrans) were restricted to the western and central regions of North America, but by the early 2000s coyotes became ubiquitous throughout the eastern United States. Information regarding morphological and genetic structure of coyote populations in the southeastern United States is limited, and where data exist, they are rarely compared to those from other regions of North America. We assessed geographic patterns in morphology and genetics of coyotes with special consideration of coyotes in the southeastern United States. Mean body mass of coyote populations increased along a west-to-east gradient, with southeastern coyotes being intermediate to western and northeastern coyotes. Similarly, principal component analysis of body mass and linear body measurements suggested that southeastern coyotes were intermediate to western and northeastern coyotes in body size but exhibited shorter tails and ears from other populations. Genetic analyses indicated that southeastern coyotes represented a distinct genetic cluster that differentiated strongly from western and northeastern coyotes. We postulate that southeastern coyotes experienced lower immigration from western populations than did northeastern coyotes, and over time, genetically diverged from both western and northeastern populations. Coyotes colonizing eastern North America experienced different selective pressures than did stable populations in the core range and we offer that the larger body size of eastern coyotes reflect an adaptation that improved dispersal capabilities of individuals in the expanding range.

Divergence, gene flow and the origin of leapfrog geographic distributions: the history of color pattern variation in Phyllobates poison-dart frogs

The geographic distribution of phenotypic variation among closely related populations is a valuable source of information about the evolutionary processes that generate and maintain biodiversity. Leapfrog distributions, in which phenotypically similar populations are disjunctly distributed and separated by one or more phenotypically distinct populations, represent geographic replicates for the existence of a phenotype, and are therefore especially informative. Phyllobates poison frogs. We found evidence for high levels of gene flow between neighboring populations but not over long distances, indicating that gene flow between populations exhibiting the central phenotype may have a homogenizing effect that maintains their similarity, and that introgression between "leapfroging" taxa has not played a prominent role as a driver of phenotypic diversity in Phyllobates. Although phylogenetic analyses suggest that the leapfrog distribution was formed through independent evolution of the peripheral (i.e. leapfrogging) populations, the elevated levels of gene flow between geographically close populations poise alternative scenarios, such as the history of phenotypic change becoming decoupled from genome-averaged patterns of divergence, which we cannot rule out. These results highlight the importance of incorporating gene flow between populations into the study of geographic variation in phenotypes, both as a driver of phenotypic diversity and as a confounding factor of phylogeographic inferences.

Interaction of hydric and thermal conditions drive geographic variation in thermoregulation in a widespread lizard

Raw data and scripts of the article "Interaction of hydric and thermal conditions drive geographic variation in thermoregulation in a widespread lizard" by Rozen-Rechels D. et al., in Ecological Monographs. These data are freely available in csv format. See the readme file for metadata explanation. Data were formatted by the first author David Rozen-Rechels and collected according to standards and procedures described in the companion journal article.   Abstract of the paper: Behavioral thermoregulation is an efficient mechanism to buffer the physiological effects of climate change. Thermal ecology studies have traditionally tested how thermal constraints shape thermoregulatory behaviors without accounting for the potential major effects of landscape structure and water availability. Thus, we lack a general understanding of the multifactorial determinants of thermoregulatory behaviors in natural populations. In this study, we quantified the relative contribution of elevation, thermal gradient, moisture gradient and landscape structure in explaining geographic variation in thermoregulation strategies of a terrestrial ectotherm species. We measured field active body temperature, thermal preferences and operative environmental temperatures to calculate thermoregulation indices, including thermal quality of the habitat and thermoregulation efficiency for a very large sample of common lizards (Zootoca vivipara) from 21 populations over 3 years across the Massif Central mountain range in France. We used an information-theoretic approach to compare eight a priori thermo-hydroregulation hypotheses predicting how behavioral thermoregulation should respond to environmental conditions. Environmental characteristics exerted little influence on thermal preference with the exception that females from habitats with permanent access to water had lower thermal preferences. Field body temperatures and accuracy of thermoregulation were best predicted by the interaction between air temperature and a moisture index. In mesic environments, field body temperature and thermoregulation inaccuracy increased with air temperature, but they decreased in drier habitats. Thermoregulation efficiency (difference between thermoregulation inaccuracy and the thermal quality of the habitat) was maximized in cooler and more humid environments and was mostly influenced by the thermal quality of the habitat. Our study highlights complex patterns of variation in thermoregulation strategies, which are mostly explained by the interaction between temperature and water availability, independent of the elevation gradient or thermal heterogeneity. Although changes in landscape structure were expected to be the main driver of extinction rate of temperate zone ectotherms with ongoing global change, we conclude that changes in water availability coupled with rising temperatures might have a drastic impact on the population dynamics of some ectotherm species.
