Anurans as prey: an exploratory analysis and size relationships between predators and their prey
(Blackwell Publishing, 2007-02-01)
The vertebrate predators of post-metamorphic anurans were quantified and the predator-prey relationship was investigated by analysing the relative size of invertebrate predators and anurans. More than 100 vertebrate predators ...
Carrion Feeding By Spiderlings Of The Cob-Web Spider Theridion evexum(Araneae, Theridiidae)
(2007)
The use of carrion to feed spiderlings has never previously been observed in spiders. Here we show that the theridiid Theridion evexum Keyserling 1884 stored dead insectan prey for up to one week prior to the emergence of ...
The peculiar case of an insectivorous iguanid lizard that detects chemical cues from prey
(2007)
Ecological and phylogenetic factors determine which sensory modalities organisms use in their day-to-day activities. Among lizards, empirical studies indicate a tight association between foraging strategies and the ability ...

Early to Middle Holocene subsistence strategies in the Pampas region: Evidence from the Arroyo Seco 2 site
(Elsevier, 2017-04)
The following paper presents an analysis of the faunal material from the Arroyo Seco 2 site dated from the Early to Middle Holocene (ca. 8500 to 5800 14C yrs B.P.). The zooarchaeological and taphonomic data presented here ...
Expanded food choice as a possible factor in the evolution of sociality of Vespidae (Hymenoptera)
(2002-01-01)
A recent theory suggests that economic considerations are more important than genetic ones in the emergence and maintenance of social behavior. Evolution of social behavior in wasps, thus, could be based on the development ...

Prey preference of the stone crab Platyxanthus crenulatus (Decapoda: Platyxanthidae) in laboratory conditions
(Sociedade Brasileira de Carcinologia, 2013-06)
The preference for a particular type of prey implies an active behavioral choice of the predator. The present work deals with the prey preference of the large stone crab Platyxanthus crenulatus among similar sized gastropods ...
Males choose to keep their heads: preference for lower risk females in a praying mantid
(Elsevier Science, 2016-06)
Male reproductive success is obviously mate limited, which implies that males should rarely be choosy. One extreme case of a reproductive (or mating) cost is sexual cannibalism. Recent research has proposed that male mantids ...
