Effects of competition and egg predation on shelter use by Octopus tehuelchus females
(Inter-Research, 2013-05)
Parental care in the ocean ranges from provision to eggs and embryos to protection from predators. In particular, nest attendance has several benefits associated with relatively higher survival rates, lower vulnerability ...
Seed size variation in the palm Euterpe edulis and the effects of seed predators on germination and seedling survival
(Elsevier B.V., 2006-05-01)
Intraspecific variation in seed size is common in wild plant populations and has important consequences for the reproductive success of individual plants. Multiple, often conflicting evolutionary forces mediated by biotic ...
Intra and interspecific interactions between aphidophagous ladybirds: the role of prey in predator coexistence
(Wiley Blackwell Publishing, Inc, 2017-03)
Cannibalism (CANN) and intraguild predation (IGP) may provide energy and nutrients to individuals and eliminate potential competitors. These negative competitive interactions could also affect the coexistence of predatory ...
Drivers of individual niche variation in coexisting species
(2018-09-01)
Although neglected by classic niche theory, individual variation is now recognized as a prevalent phenomenon in nature with evolutionary and ecological relevance. Recent theory suggests that differences in individual ...
Seed deposition patterns and the survival of seeds and seedlings of the palm Euterpe edulis
(Elsevier B.V., 2001-07-01)
The seed deposition pattern created by a seed disperser is one of the components of the efficiency of a species as seed disperser, and ultimately may influence the recruitment of a plant species. In this study, we used the ...

Disadvantages of living in a populous neighborhood for sit-andwait predators: Competition for space reduces pit-trap size in antlion larvae
(Blackwell Publishing Ltd, 2020-11-01)
The study of how trap design responds to biotic and abiotic conditions can help to
understand the selective forces affecting the foraging of trap-building organisms.
We experimentally tested whether pit design can be ...
Effects of intraguild interactions on Anticarsia gemmatalis and Chrysodeixis includens larval fitness and behavior in soybean
(Wiley-Blackwell, 2021-03-10)
BACKGROUND Crop pest management requires an understanding of the complex interactions among species that potentially impact crop yield. In soybean, the velvetbean caterpillar, Anticarsia gemmatalis (Hubner), and the soybean ...
The defensive behavioral patterns of captive white-lipped and collared peccary (Mammalia, Tayassuidae): an approach for conservation of the species
(Springer, 2017-06-01)
Defensive behavioral patterns in response to human-induced rapid environmental change can affect animals' fitness and may play a role in species conservation status. To test this hypothesis, we compared the risk assessment ...
Keeping safe and fed: large heterospecific shorebird flocks to decrease intraspecific competition
(Wiley-Blackwell, 2020-01-01)
Shorebirds join cohesive flocks for safety. The joining of individuals of several species in large heterospecific flocks can optimise individual vigilance and foraging. However, a large number of conspecific individuals ...
