We consider a predator–prey system with cooperative hunting. The parameter space of the is divided into several mutually exclusive regions. Based on investigation dynamical properties in each region, we provide complete description global dynamics, including stability, Hopf bifurcation and its directions, existence limit cycles. By comparing this system’s dynamics to those without hunting, it f...

Underwater pollution incidents occur frequently, and obtaining accurate information about their exact location real-time situation is helpful for promptly formulating plans to contain mitigate the situation. Autonomously adjusting position of sensors optimal coverage monitoring regions interest (e.g., oil spill zones, chemical contamination areas) in real time a significant challenge. To this e...

The impact of hunting (selective harvest, trophy hunting) on the demography of mammals is well documented. However, despite continual year-round hunting of bison in some populations, little is known about how the behavior of survivors may be altered. Therefore, in this initial study, we used focal-animal observations in adjacent populations of continually hunted and protected Plains bison (Biso...

shikārnāmeh-ye malikshāhī (the malikshāhī book of hunting) which is also known as shikārnāmeh-ye khusrawī, is a book prepared in the 5th ah/11th ad century by malikshāh’s order and niẓām al-mulk’s patronage. the book’s actual redaction is due to abū al-ḥassan niyshābūrī. this book refers to many other books on falconry and hunting (bāznāmeh and shikārnāmeh) especially the translation of the “sh...

All known chimpanzee populations have been observed to hunt small mammals for meat. Detailed observations have shown, however, that hunting strategies differ considerably between populations, with some merely collecting prey that happens to pass by while others hunt in coordinated groups to chase fast-moving prey. Of all known populations, Taï chimpanzees exhibit the highest level of cooperatio...

Hunting activities can affect game species in several ways; however, indirect effects of hunting on non-game species have received less attention than direct effects on game species, even though such potential effects could be crucial in some situations. There is ongoing concern that the critically endangered Florida panther Puma concolor coryi may be influenced by hunting activity, in terms of...

BACKGROUND The moose (Alces alces) is an intensively managed keystone species in Fennoscandia. Several aspects of reproduction in moose have not been fully elucidated, including puberty, timing of mating and oestrus, and the length of the oestrus period. These aspects are relevant for an adaptive management of moose with respect to harvest, population size, demography and environmental conditio...

Previous studies from our laboratory have shown that insect hunting is associated with a distinct Fos up-regulation in the ventrolateral caudoputamen at intermediate rostro-caudal levels. It is largely known that ventrolateral striatum participates in the control of orofacial movements and forepaw usage accompanying feeding behavior, but there has been no study investigating its possible roles ...
