Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Gemma E. White, Grant C. Hose, Culum Brown

Culum Brown, PhD

Rock pools can be found in inter-tidal marine environments worldwide; however, there have been few studies exploring what drives their, fish species composition, especially in Australia. The rock-pool environment is highly dynamic and offers a unique natural laboratory to study the habitat choices, physiological limitations and adaptations of inter-tidal fish species. In this study rock pools of the Sydney region were sampled to determine how the physical (volume, depth, rock cover and vertical position) and biological (algal cover and predator presence) parameters of pools influence fish distribution and abundance. A total of 27 fish species representing 14 families was observed …

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus

Philip J. Nyhus

Human interactions with wildlife are a defining experience of human existence. These interactions can be positive or negative. People compete with wildlife for food and resources, and have eradicated dangerous species; co-opted and domesticated valuable species; and applied a wide range of social, behavioral, and technical approaches to reduce negative interactions with wildlife. This conflict has led to the extinction and reduction of numerous species and uncountable human deaths and economic losses. Recent advances in our understanding of conflict have led to a growing number of positive conservation and coexistence outcomes. I summarize and synthesize factors that contribute to conflict, …

Responses Of Four Arthropod Prey Species To Mechanosensory, Chemosensory And Visual Cues From An Arachnid Predator: A Comparative Approach, Scott Kight

Scott Kight

Comparisons of multiple invertebrate prey species to direct predator sensory cues are relatively uncommon. We compared prey responses to arachnid predators (Araneae: Lycosidae) of four species: Blattella germanica (Blattodea: Blattellidae), Acheta domesticus (Orthoptera: Gryllinae), Armadillidium vulgare (Oniscidea: Armadillidae), and Porcellio laevis (Oniscidea: Porcellionidae). Prey experienced combinations of direct mechanosensory, chemosensory or visual cues. All species responded to all cues, but response structure differed among species. Mechanosensory and chemosensory predator cues elicited frequent shifts between behaviors, whereas visual stimuli tended to diminish responses. Mechanosensory stimuli produced the most extreme responses, particularly in crickets and cockroaches, but responses to mechanosensory stimuli diminished …
