Season does not influence the response of great tits (Parus major) to allopatric mobbing calls

Abstract Many species of birds emit mobbing calls to recruit prey to join mobbing events. This anti-predator strategy often involves several species and, therefore, implies heterospecific communication. Some species of …

Association between visual cues and time of day in an ant

Abstract On the basis of what is known about the biology and the cognitive abilities of the workers of the ant Myrmica sabuleti studied at a collective level, we wondered …

Locomotion and flow speed preferences in natural habitats by large water striders, Ptilomera tigrina, with micro-morphological adaptations for rowing

Abstract Water strider (Gerridae) morphology and behavior have become the focus of interdisciplinary research in biological diversification and bio-inspired technology. However, the diversity of behaviors and morphology of the large-sized …

Effect of diet quality on food consumption and body mass in Microtus pennsylvanicus

Abstract Small herbivores, such as meadow voles (Microtus pennsylvanicus), have high metabolic requirements but small gut capacities. Therefore, they should prefer food high in macronutrients, like protein, and low in …

Antibiotics affect migratory restlessness orientation

Abstract The role of microbiome in shaping animal’s behavior is well established. Accordingly, the use of antibiotics may have profound effects on behavior, which are seldom examined. Recently, the symbiotic …

Reproductive behavior of endangered spined loach Cobitis magnostriata in the field

Abstract Spined loaches, Cobitis spp., have been studied in broad fields of research. Particularly, this taxon has attracted attention because of sexual interactions, such as reproductive interference and hybrid speciation, …

Nocturnal light-specific temporal partitioning facilitates coexistence for a small mesopredator, the eastern spotted skunk

Abstract Eastern spotted skunks are of conservation concern, where competition and predation are possible causes of their decline. Using camera traps at a food subsidy, we investigated nocturnal temporal overlap …

Predation strategy of the brown widow spider Latrodectus geometricus Koch, 1841 against prey with different defensive mechanisms

Abstract Predators, such as spiders, may modulate their predatory behavior according to the defensive mechanisms of their prey. This study analyzed the prey capture behavior of Latrodectus geometricus spiders, specifically …
