Predation ability of freshwater crabs: age and prey-specific differences in Trichodactylus borellianus (Brachyura: Trichodactylidae)
(Taylor & Francis, 2013-06)
Freshwater crabs are rarely represented in food webs and their role in these ecosystems has been largely ignored. Trichodactylus borellianus is an omnivorous crab species that has a diverse natural trophic spectrum. This ...
Gut evacuation time of macrobrachium borellii (Caridea: Palaemonidae) feeding on three types of prey from the littoral-benthic community
(Crustacean Society, 2011-10)
Gut evacuation time is a very useful parameter that allows us to understand the daily trophic cycle of a predator. Macrobrachium borellii is an inhabitant of the littoral-benthic community of the Paran River system that ...
Age-related prey selectivity and foraging efficiency in Olrog's Gulls Larus atlanticus feeding on crabs in their non-breeding grounds.
(Csiro Publishing, 2011-05)
Foraging ecology is an essential component of the life history of a species and a good understanding of foraging ecology is especially important for threatened species where prey populations may be adversely affected by ...
Spatial and temporal taphonomic study of bone accumulations of the burrowing owl (Athene cunicularia) in central Argentina
(Elsevier, 2020-04)
Athene cunicularia is a very common opportunistic raptor inhabiting diverse environments of South America. It has variable hunting behavior and diet habits, feeding mostly on arthropods and nocturnal and diurnal micromammals. ...
Adelomelon ancilla: a predator neogastropod in Patagonian benthic communities
(Bailey-Matthews Shell Museum, 2009-12)
Adelomelon ancilla, a volutid commonly found in shallow waters of northern Patagonia, is a top predator in the benthic communities of this region. This species presents an anemone epibiosis (Antholoba achates) that may ...
Actualistic taphonomic study of the rodents digested by the Achala culpeo fox (Lycalopex culpaeus smithersi) in the highlands of central Argentina
(Wiley Blackwell Publishing, Inc, 2021-06-07)
We present the first actualistic study of the rodents consumed by the South American foxLycalopex culpaeus smithersi (Achala culpeo fox), a subspecies of the culpeo fox that is endemicto the highlands of central Argentina. ...
Feeding behavior of Adelomelon ancilla (Ligfoot, 1786): A predatory neogastropod (Gastropoda: Volutidae) in Patagonian benthic communities
(Bailey-Matthews Shell Museum, 2009-06)
Adelomelon ancilla, a volutid commonly found in shallow water in northern Patagonia, is a top predator in the benthic communities of this region. This species presents an anemone (Antholoba achates) epibiosis that may ...
Taphonomic signature of Geoffroy's cat (Leopardus geoffroyi) on small sized preys: A comparative study of ingested and non-ingested leporid bones
(Elsevier, 2020-06)
In order to generate a more comprehensive understanding of the accumulations produced by small-sized predators in the fossil record, a feeding experiment with captive Geoffroy's cat was carried out and the bone modifications ...
From owl prey to human food: taphonomy of archaeological small mammal remains from the late Holocene wetlands of arid environments in Central Western Argentina
(Springer, 2020-11)
The present study analyses small mammal bone and tooth accumulations recovered in three open-air archaeological sites from northern Mendoza (Argentina) in the central Monte Desert, one of the most arid rangelands of South ...
Going underwater: Multiple origins and functional morphology of piercing-sucking feeding and tracheal system adaptations in water scavenger beetle larvae (Coleoptera: Hydrophiloidea)
(Oxford University Press, 2021-09)
Larvae of water scavenger beetles (Coleoptera: Hydrophiloidea) are adapted to a wide variety of aquatic habitats, butlittle is known about functional and evolutionary aspects of these adaptations. We review the functional ...
