Manually monitoring the population displacement of fish species and the whale individuals is a painful and definitely unscalable process. Video data about fishes often require laborious visual analysis, moreover biologists often use photos of whale caudal for further analysis as it is the most discriminant pattern for distinguishing an individual whale from another. Therefore two challenges wer...

Artificial fish swarm algorithm (AFSA) is a population based optimization technique inspired by social behavior of fishes. In past several years, AFSA has been successfully applied in many research and application areas. The behavior of fishes has a crucial impact on the performance of AFSA, such as global exploration ability and convergence speed. How to construct and select behaviors of fishe...

Elevated carbon dioxide (CO(2)) has recently been shown to affect chemosensory and auditory behaviour, and activity levels of larval reef fishes, increasing their risk of predation. However, the mechanisms underlying these changes are unknown. Behavioural lateralization is an expression of brain functional asymmetries, and thus provides a unique test of the hypothesis that elevated CO(2) affect...

Understanding population-level responses to novel selective pressures can elucidate evolutionary consequences of human-altered habitats. Stream impoundments (reservoirs) alter riverine ecosystems worldwide, exposing stream fishes to uncommon selective pressures. Assessing phenotypic trait divergence in reservoir habitats will be a first step in identifying the potential evolutionary and ecologi...

REGIONAL EXTINCTION RISK AND CONSERVATION PRIORITIES FOR PERSIAN GULF MARINE BONY FISHES Jack R. Buchanan Old Dominion University, 2016 Advisor: Dr. Kent Carpenter Around the world, protected areas are the primary conservation measure used to combat biodiversity loss; however, these are often established without comprehensive species-specific information, leading to placement in areas that ofte...

As in many regions of the world, marine fishes and invertebrates along the Pacific coast of the United States have long been subjected to overexploitation. Despite this history, however we lack basic information on the current status of many fishes along this coastline. We used data from a quarter century of fishery-independent, coast-wide trawl surveys to study systematically the demersal fish...
