Priority effects and desert anuran communities
The roles of priority effects and predation in structuring anuran communities have not been considered important in desert environments characterized by highly ephemeral pools and anuran species that breed synchronously. Predation is one mechanism that can set the stage for priority effects to be important, especially in ephemeral pools where resources are limiting and densities are high. We ob...
متن کاملDevelopmental alterations and osmoregulatory physiology of a larval anuran under osmotic stress.
Water salinity represents an environmental stress for many species. Amphibians are particularly sensitive because they are generally poor osmoregulators, and most species are completely absent from brackish and saline environments. We experimentally examined the effect of different salinity levels on larvae of the toad Bufo calamita L., a species that occupies freshwater ponds but can also bree...
متن کاملInteractive effects of pesticide exposure and habitat structure on behavior and predation of a marine larval fish.
Coastal development has generated multiple stressors in marine and estuarine ecosystems, including habitat degradation and pollutant exposure, but the effects of these stressors on the ecology of fishes remain poorly understood. We studied the separate and combined effects of an acute 4 h sublethal exposure of the pyrethroid pesticide esfenvalerate and structural habitat complexity on behavior ...
متن کاملPredation in two species of leech under laboratory conditions
Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...
