Does Lagenorhynchus cruciger possess an automatic gain control to adjust its hearing during echolocation? (Research Proposal Sample)
A biological RESEARCH priposal on Lagenorhynchus cruciger possess an automatic gain control to adjust its hearing during echolocation. The guidelines was to come up with a clear hypothesis and testable. The methods were to be complete and logical . on the predictions I was to show if the null hypothesis align with the methods a the hypothesis. In discussion I was to discuss if the implication of the null hypothesis being rejected or acceptable if clearly discussed .source..
Does Lagenorhynchus cruciger possess an automatic gain control to adjust its hearing during echolocation?
Echolocation is an evolutionary adaptation of some animals to have the ability to assess the environment by emitting sounds and listening to echoes reflecting off present objects. This adaptation is used by these animals regularly in their natural environments. Dolphins fall in this category of animals having the ability to make a variety of sounds regarded as whistles, clicks, barks, screams, squawks and buzzes (Rasmussen et al. 2002). For feeding purposes, dolphins seek entities that are substantially smaller than themselves which requires making accurate discrimination of objects around it. Hourglass dolphins (Lagenorhynchus cruciger) produces narrowband, high-frequency echolocation (NBHF) clicks that they employ in communication, navigation, orientation, foraging, prey capture and avoiding predation in their aquatic environments (Li et al. 2011). This adaptation has over the years been fine-tuned under evolutionary selective pressures to serve in these roles.
