Ranavirus in wood frogs (Rana sylvatica): potential sources of transmission within and between ponds.
Members of the genus Ranavirus (family Iridoviridae) can cause catastrophic mortality of pond-breeding amphibians and are associated with an emerging infectious disease that may be contributing to amphibian declines. We conducted three experiments to examine factors that may affect transmission both within and between local breeding populations of the wood frog (Rana sylvatica). In a laboratory...
متن کاملLotus-fish Culture in Ponds: Recycling of Pond Mud Nutrients
An experiment was conducted in nine 200-m2 fertilized earthen ponds at the Asian Institute of Technology, Thailand, from January to September 2000. This experiment was designed to assess the recovery of pond mud nutrient by lotus (Nelumbo nucifera), to assess pond mud characteristics after lotus-fish co-culture, and to compare fish growth with and without lotus integration. There were three tre...
متن کاملSemi-intensive Culture of Red Tilapia in Brackishwater Ponds
An experiment was conducted at the Asian Institute of Technology, Thailand, to investigate effects of fertilization rates and salinity levels on the growth of sex-reversed Thai red tilapia (Oreochromis sp.). The experiment was designed to test two fertilization rates (28 kg nitrogen and 7 kg phosphorus ha-1 wk-1, N:P = 4:1; and 14 kg N and 7 kg P ha-1 wk-1, N:P = 2:1) and three salinity levels ...
متن کاملHabitat connectivity and resident shared predators determine the impact of invasive bullfrogs on native frogs in farm ponds.
Habitat connectivity is considered to have an important role on the persistence of populations in the face of habitat fragmentation, in particular, for species with conservation concern. However, it can also impose indirect negative effects on native species through the spread of invasive species. Here, we investigated direct and indirect effects of habitat connectivity on populations of invasi...
متن کاملDifferential jumping performance in newly metamorphosed Blanchard’s cricket frogs, Acris blanchardi (Anura: Hylidae), from fish- and invertebrate-dominated ponds
Differential jumping performance in newly metamorphosed Blanchard’s cricket frogs Acris blanchardi (Anura: Hylidae) from fishand invertebrate-dominated ponds. Organisms that adopt phenotypically plastic anti-predator strategies during larval stages may incur fitness costs later in development. These costs are typically difficult to define in many species. The difficulty of identifying ecologica...
