Abstract:
... The inability to maintain signal detection performance with time on task, or response decrement, has been widely studied. In animals with small brains, the ability to filter out repetitive, irrelevant stimuli may prevent the nervous system from being saturated with information. However, animals must be particular to which stimuli they attend and those to ignore, as mistakes may be costly. We explo ...

Abstract:
... The concept of a carrying capacity of an environment for a population has been an effective way of introducing a connection between populations and their environment. This approach has been particularly effective in heuristic Lotka–Volterra models of competition and predation that provide a basis for theoretical considerations of population interactions. However, the concept has proved less useful ...

Abstract:
... Reducing predation risk is fundamental to many animals. Among those, social animals are studied for one type of anti-predator defense. They aggregate in certain habitats to dilute risk, share vigilance, defend each other, and reduce their chances of being attacked. However, this tendency is not necessarily unique: solitary animals may also benefit from the presence of conspecifics. Thus, we hypoth ...

Abstract:
... Studies in paleoecology utilizing the record of drilling predation to draw ecological and evolutionary inferences are likely subject to durophagy bias: the inflation of observed drilling frequency due to the removal of undrilled prey via crushing predation. Although this bias was recognized nearly four decades ago, it is commonly ignored in studies of drilling predation. Here we quantify the poten ...

Abstract:
... Food resources can occur heterogeneously in space or time and differ in their abundances. A forager should be able to determine the value of a patch and choose optimally how to exploit it. However, patch choice and exploitation may be influenced by predation risk. Using the Giving up Densities (GUDs) technique, we evaluated goldfish patch assessment and choice in a binary patch choice experiment. ...

Abstract:
... Rodents adjust predation and hoarding behavior according to the probability of their hoarding seeds being stolen by competitors. Rodents eat unsafe seeds (seeds more likely to be stolen) immediately and keep safe seeds (seeds less likely to be stolen) for a long time. Rodents spread their seeds in many small “storehouses” when the probability of hoarded seeds being stolen is high and hoard many se ...

Abstract:
... ‘Omnivory’, a widespread mechanism in interacting populations, is defined as feeding on more than one trophic levels. In this work we have considered a three species model consisting of prey, intermediate predator that predates upon prey and top predator with intraguild predation. It is well known that intraguild predation destabilizes the food webs consisting of three and more trophic levels, and ...

Abstract:

Positive relationship between diversity and biomass was often observed by empirical experiments at the community level, but the effects of species interactions on community total biomass have been rarely explored from a network perspective.

In March 2018, a subadu ...

Abstract:
... Orb-web spiders typically construct their webs with a vertical asymmetry: the hub, or meeting point of the radial threads, is often above the geometric center of the web. Previous explanations for this asymmetry involve differences in up/down running speed and mass, but fail to account adequately for ontogenetic changes in vertical asymmetry. The current article argues that the hub location is det ...

Abstract:
... The best documented method to decrease predation of breeding seabirds by gulls are culling regimes; however, studies on the effectiveness of this method show ambiguous results. Here we tested an alternative method, using bamboo canes erected in four breeding sites of Arctic Tern Sterna paradisaea as a gull‐deterrent. Although we found fewer predation attempts in the caned areas than in the control ...

Abstract:
... Inducible defences against predation are widespread in the natural world, allowing prey to economise on the costs of defence when predation risk varies over time or is spatially structured. Through interspecific interactions, inducible defences have major impacts on ecological dynamics, particularly predator–prey stability and phase lag. Researchers have developed multiple distinct approaches, eac ...

Public feeding of free-roaming cats subsidizes their population growth, and has consequences in highly interconnected ecosystems including predation of native wildlife and alteration of their behavior and populations. Research is needed to explain, predict, and possibly curb public feeding. We conducted a theoretically informed analysis of key beliefs underlying intentions to feed free-roaming cat ...

In the last 30 years, islands and fenced exclosures free of introduced predators (collectively, havens) have become an increasingly used option for protecting Australian mammals imperiled by predation by introduced cats (Felis catus) and foxes (Vulpes vulpes). However, Australia's network of havens is not expanding in a manner that maximizes representation of all predator‐susceptible taxa, because ...

Based on the trophic field overlap of species in the food webs, we propose using the weighted trophic field overlap (WTO) to determine the uniqueness of species in a topological network by considering the food web structure and the proportions of prey in the diets of predators. This proposed method measures uniqueness structurally and mathematically and considers cannibalism and mutual predation b ...
