Optimal foraging constrains macroecological patterns: body size and dietary niche breadth in lizards
Aim To explore and identify probable mechanisms contributing to the relationships among body size, dietary niche breadth and mean, minimum, maximum and range of prey size in predaceous lizards. Location Our data set includes species from tropical rainforests, semi-arid regions of Brazil, and from deserts of the south-western United States, Australia and the Kalahari of Africa. Methods We calcul...
متن کاملEcological divergence and sexual selection drive sexual size dimorphism in New World pitvipers (Serpentes: Viperidae).
Hypotheses for the origin and maintenance of sexual size dimorphism (SSD) fall into three primary categories: (i) sexual selection on male size, (ii) fecundity selection on female size and (iii) ecological selection for gender-specific niche divergence. We investigate the impact of these forces on SSD evolution in New World pitvipers (Crotalinae). We constructed a phylogeny from up to eight gen...
متن کاملTemperature trends at high elevations: Patterns across the globe
[1] Most climate models suggest amplification of global warming in high mountains, but observations are less clear. Using comprehensive, homogeneity-adjusted temperature records from over 1000 high elevation stations across the globe, we examine the causes of changing temperature trends with elevation, assessing the roles of free atmospheric change, topography (exposure and aspect), and cryosph...
متن کاملInterspecific pairwise relationships among body size, clutch size and latitude: deconstructing a macroecological triangle in birds
A large body of research dating back to the 19th century has shown evidence for consistent relationships between ecological variables across geographical space (Lomolino et al., 2006; Gaston et al., 2008). These so-called ecogeographical ‘rules’ are often observed both within and among species and across lineages. Here we focus on three of the most familiar Department of Biology, University of ...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
