متن کاملPeripheral obstructions influence marmot vigilance: integrating observational and experimental results
Animals generally allocate some time during foraging to detecting predators. We used a combination of observations and an experiment to examine how vegetation height and peripheral obstructions influence vigilance by foraging yellow-bellied marmots (Marmota flaviventris). First, we analyzed a large sample of observations of marmots foraging in nature. Marmots increased vigilance with vegetation...
متن کاملDiffuse Lower Motor Neuron Disorders
One of the causes of acute quadriparesis or quadriplegia is that of diffuse lower motor neuronal (LMN) dysfunction, resulting in diminished to absent reflexes in all 4 legs. In this instance the immediate differential diagnosis must include acute polyradiculoneuropathy (previously discussed), Coral snake envenomation, tick paralysis, and botulism. Other causes which normally result in normal re...
متن کاملA survey of Karoo tick paralysis in South Africa.
Recent research interest in Karoo tick paralysis and its vector. Ixodes rubicundus, prompted this survey to determine the economic implications of this disease. The survey indicated relatively high losses caused by the condition, identified the stock involved and provided data on the incidence of paralysis and on the control methods employed. Recommendations are made to institute chemical contr...
