Studies of hand use in nonhuman primates suggest that several species exhibit hand preferences for a variety of tasks. The majority of studies, however, focus on the lateralized hand use of captive nonhuman primate populations. Although captive settings offer a more controlled environment for assessing hand preferences, studies of wild populations provide important insights into how handedness ...

Omnivorous arthropods make dietary choices according to the environment in which they forage, mainly availability/quality of plant and/or prey resources. Such decisions and their subsequent impacts on life-history traits may be affected by the availability of nutrients and water to plants, that is, through bottom-up forces. By setting up arenas for feeding behavior observation as well as glassh...

Sustainability in food production is an increasingly discussed issue nowadays; therefore, demands for research that can reduce costs and ensure the quality autonomy of are relevant, with attention to use plants due their importance biodiversity. Thus, objective this was evaluate bioactivity, feeding preference, oviposition preference Miconia albicans botanical extracts at concentrations 1%, 5%,...

The food and feeding habit of beardless barb, Cyclocheilichthys apogon (Valenciennes, 1842), from family Cyprinidae was investigated by stomach content analyses of 374 collected fish in two consecutive reservoirs Temengor and Bersia Reservoirs which are separated by Temengor Dam. The main aim of this study was to compare the stomach contents of C. apogon between these two reservoirs in wet and ...

  Neogobius caspius is an endemic species of the Caspian Sea which plays an important role in food chain as a predatory fish. The main aim of this study was to investigate selected feeding characteristics of Neogobius caspius in the south west coasts of the Caspian Sea. Monthly sampling was carried out using a bottom trawler at three stations (Astara, Anzali and Chabuksar) in three depths (0-5,...

The sea urchin, Mesocentrotus nudus, is widely distributed in North West Pacific regions. It has a substantial impact on macroalgal communities as generalist herbivore. This study examined various aspects of its feeding ecology, including algal preference, foraging behaviors, and possible effects past history preference. We used six common species (Ulva australis, Undaria pinnatifida, Sargassum...

The present work tested whether Triatoma pseudomaculata Corrêa & Espínola shows behavioral traits indicating that it is capable of feeding on arthropods. We consistently observed nymphs extending their proboscis in the direction of cockroaches and attempting to bite. Insects presented a preference for biting specific cockroach body parts. Our results suggest that arthropod hemolymph represents ...

" Agapeta zoegana oviposited significantly more on rosette and one-stem plants. " 2 plants had significantly greater A. zoegana larval density than 4 plants. " Significant correlation between the number of larvae infesting plant roots and Centaurea stoebe root diameter. " Cyphocleonus achates fed more frequently on multiple-stem 4 plants. " Arion lusitanicus had a strong feeding preference for ...
