Neighbor Colonies Affect Level of Foraging in the Generalist Ant Pheidole oxyops (Hymenoptera: Formicidae)
(2021-06-01)
Pheidole oxyops Forel (Hymenoptera: Formicidae) is a generalist ant that can display passive and active forage strategies. Moreover, this species can forage actively for a variety of food resources from plant debris to ...
Ammonia volatilization, forage accumulation, and nutritive value of marandu palisade grass pastures in different n sources and doses
(2021-09-01)
The reduction in ammonia (NH3) losses from volatilization has significant implications in forage production. The objective of this study was to evaluate the impact of N fertilizers (urea, ammonium nitrate, and ammonium ...
A breath of fresh air in foraging theory: The importance of wind for food size selection in a central-place forager
(University of Chicago Press, 2017-09)
Empirical data about food size carried by central-place foragers do not often fit with the optimum predicted by classical foraging theory. Traditionally, biotic constraints such as predation risk and competition have been ...
Nitrogen management of forage grasses for nutrition, seed production, and nutrients in residual straw
(Empresa Brasil Pesq Agropec, 2019-01-01)
The objective of this work was to evaluate the nutrition, accumulation of nutrients in residual straw, pure seed yield, and seed quality of the tropical forage grasses 'Mombaca' and 'Xaraes' subjected to topdressing with ...
MORPHOGENESIS, STRUCTURAL CHARACTERISTICS AND FORAGE ACCUMULATION OF Megathyrsus maximus BRS ZURI SUBJECTED TO NITROGEN FERTILIZATION
(Inst Zootecnia, 2020-01-01)
Nitrogen fertilization permits to increase the carrying capacity of pastures; however, the use of high doses can have negative effects on the growth of forage grasses. Therefore, the aim of this study was to evaluate the ...
