The effects of phenotypic plasticity and local adaptation on forecasts of species range shifts under climate change.
TLDR
It is shown that when population differentiation is accounted for and dispersal is restricted, forecasts of species range shifts under climate change are even more pessimistic than those using the conventional assumption of homogeneously high plasticity across a species' range. Expand
Some vaguely explored (but not trivial) costs of tail autotomy in lizards.
TLDR
It is found that original tails displace further and at greater velocity than regenerated tails, indicating that the anti-predation responses of a lizard probably changes according to whether its tail is original or regenerated. Expand
DIET OF SOUTH AMERICAN FUR SEALS (ARCTOCEPHALUS AUSTRALIS) IN ISLA DE LOBOS, URUGUAY
TLDR
Observations suggests that Arctocephalus australis is a trophic generalist with the potential to prey on a wide range of species, although most of the diet is comprised of relatively few species. Expand
Diet of the South American frog Leptodactylus ocellatus (Anura, Leptodactylidae) in Uruguay
TLDR
The diet of Leptodactylus ocellatus was studied in specimens collected at Maldonado Department (Uruguay), where monthly surveys were made between August 1998 and March 2000 and major differences on diet composition were found between extreme age classes (froglets and adults). Expand
Seasonal activity and the body size-fecundity relationship in a population of Physalaemus gracilis (Boulenger, 1883) (Anura, Leptodactylidae) from Uruguay
TLDR
Regression analysis showed that the BSF relationship varied with size, and that larger females had a steeper slope than smaller females, which indicates that smaller females invested less energy in their offspring than larger females. Expand
Latitudinal Patterns in Phenotypic Plasticity and Fitness-Related Traits: Assessing the Climatic Variability Hypothesis (CVH) with an Invasive Plant Species
TLDR
The results suggest that the positive relationship found between phenotypic plasticity and geographic latitude could have very deep implications on future species persistence and invasion processes under a scenario of climate change. Expand
The effect of short- and long-term fasting on digestive and metabolic flexibility in the Andean toad, Bufo spinulosus
TLDR
The results suggest that amphibian persistence in highly seasonal environments is related to a large capacity of phenotypic flexibility at different organisational levels; an ability that may be related to the extensive ranges of temporal existence and geographic distribution of these vertebrates. Expand
OVERLAP BETWEEN PINNIPED SUMMER DIET AND ARTISANAL FISHERY CATCHES IN URUGUAY
TLDR
Diet data for both pinnnipeds together with artisanal fisheries catch data were analyzed to estimate the overlap in prey species and sizes, and the main difference between the two pinniped diets was that O. flavescens showed a more diverse diet than A. australis. Expand
Latitudinal Patterns in Rodent Metabolic Flexibility
TLDR
Evaluating the correlation between absolute metabolic scope during cold exposure (an instantaneous measure of metabolic flexibility) and different geographic and climatic variables for 48 rodent species suggests that an increase in physiological flexibility with latitude may hold for many phenotypic traits. Expand
Calling activity patterns in an anuran assemblage: the role of seasonal trends and weather determinants
Calling activity of anuran assemblages were related to seasonal changes in weather factors such as temperature and rainfall. We evaluated the suitability of these variables as determinants ofExpand
