Hyoid skeleton, its related muscles, and morphological novelties in the frog Lepidobatrachus (anura, ceratophryidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2009-11)
Many traits of the skull of ceratophryines are related to the capture of large prey independently of aquatic or terrestrial feeding. Herein, detailed descriptions of the development of hyoid skeleton and the anatomy of ...
Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae)
(Fundação Oswaldo Cruz, 2011-04)
Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of ...
Feeding and osmoregulation in the euryhaline crab Neohelice granulata: Digestive parameter responses
(Brill Academic Publishers, 2019-09)
When a species often experiences variation in its environmental conditions, metabolic flexibility is required. We studied the duration of the digestive cycle and the activity of key digestive enzymes (proteolytic, amylase, ...
Food intake and the significance of feeding in Qom children of northern Argentina
(Oxford University Press, 2020-11)
Background: As part of the ubiquitous nutritional transition indigenous are experiencing, the typical diet of most indigenous communities is being substituted by one with high-fat and high-energy-density foods. Domestic ...
Daily feeding site selection of cattle and sheep co-grazing a heterogeneous subtropical grassland
(2014-03)
Effective management of livestock grazing on heterogeneous subtropical grasslands requires understanding the relative role played by factors that determine spatial distribution patterns of animals. We conducted a 2 year ...
Foraging patterns of breeding Dolphin Gulls Larus scoresbii at Punta Tombo, Argentina
(Wiley Blackwell Publishing, Inc, 2005-06)
The Dolphin Gull Larus scoresbii is a little‐known, rare species endemic to southern South America. Knowledge of its feeding ecology is essential for development of management and conservation strategies. To obtain information ...
Patterns of sleeping site and sleeping tree selection by black-and-gold Howler monkeys (alouatta caraya) in northern Argentina
(Springer/Plenum Publishers, 2019-06)
The selection of sleeping sites and sleeping trees in nonhuman primates is related to social and ecological factors. We investigate the role of body stability, risk of parasite infection, access to food, and range defense ...
Ecomorphological patterns in otoliths of tropical fishes: assessing trophic groups and depth strata preference by shape
(Springer, 2020-03-02)
The morphology and morphometry of otoliths have emerged as powerful indicators of ecological characteristics of fishes. However, shape descriptors that can accurately predict well-documented functions played by species in ...
Feeding rates and food conversion efficiencies in the apple snail pomacea canaliculata (Caenogastropoda: Ampullariidae)
(Institute of Malacology, 2009-08-01)
Pomacea canaliculata is the only freshwater snail listed as one of the 100 worst invaders worldwide. Recent studies have demonstrated that small Pomacea snails have higher foraging and competitive abilities than larger ...
