Phymaturus Palluma (High Mountain Lizard) diet
(Society for the Study of Amphibians and Reptiles, 2018-03)
Phymaturus palluma is a medium-sized, saxicolous, viviparous, and herbivorous lizard that inhabits the Altoandina phytogeographic province in the Andes Highlands, Argentina. Populations are restricted to rocky outcrops, ...
Diet of Neotropical parrots is independent of phylogeny but correlates with body size and geographical range
(Wiley Blackwell Publishing, Inc, 2018-10)
Body mass and geographical range are two main drivers of diet in animals, yet how these factors influence diet in the morphologically and ecologically diverse avian group of Psittaciformes is little known. We reviewed ...
Diet Variation of a Generalist Predator, the American Kestrel Falco sparverius, in a Gradient of Agricultural Intensification in Central Argentina
(Polish Academy of Sciences. Museum and Institute of Zoology, 2021-03-20)
Agricultural expansion at the expense of natural habitats and the intensification processes in agricultural production are globally among the main causes of biodiversity and ecosystem services loss at large scale. This ...
Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes
(Academic Press Ltd - Elsevier Science Ltd, 2019-10)
The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ...
Effects of intermittent versus continuous dieting on weight and body composition in obese and overweight people: a systematic review and meta-analysis of randomized controlled trials
(Nature Publishing Group, 2018)
Background: Intermittent dieting may be an alternative to continuous dieting for weight reduction. Objective: To evaluate the effect of intermittent dieting versus continuous dieting on weight and body composition in ...
Diet of Tadarida brasiliensis (Mammalia, Chiroptera) in the Northwestern Argentina
(Polish Academy of Sciences, 2018-06)
In Argentina, the study of feeding habits of bats was practically restricted to frugivorous species, whereas data on the insectivorous bat diet was scarce and anecdotal. Thus, the aim of this study was to analyze the diet ...
Contribution of recreational fisheries to the diet of the opportunistic Kelp Gull
(Wiley Blackwell Publishing, Inc, 2018-12)
We assessed Kelp Gull (Larus dominicanus) diet composition complementing conventional and stable isotope methods to determine the relevance of food derived from recreational fisheries. To achieve this goal, we quantified ...
Effect of urea inclusion in diets containing corn dried distillers grains on feedlot cattle performance, carcass characteristics, ruminal fermentation, total tract digestibility, and purine derivatives-to-creatinine index
(American Society of Animal Science, 2015-01)
Increased availability of rapidly fermentable carbohydrates and a great proportion of corn-derived CP in the diet may result in a degradable intake protein (DIP) deficit. Therefore, ruminal DIP deficit may result from high ...
Seasonal variation in feeding habits and diet selection by wild boars in a semi-arid environment of Argentina
(Polish Academy of Sciences, 2013-01)
The wild boar, Sus scrofa, was first introduced for hunting purposes in Argentina in 1906 and presently occupies a wide range of habitats. Understanding the food habits of invasive species is important for predicting the ...
Diet complementation as a frequency-dependent mechanism conferring advantages to rare plants via dispersal
(Wiley Blackwell Publishing, Inc, 2018-10)
We used an agent-based model to test the hypothesis that diet complementation by frugivores can promote the persistence of rare plant species in communities (DCH). Models simulated bird movement, frugivory, seed dispersal ...
