Environmental Instability and the Structure of Temporary Pond Zooplankton Communities
Chapter I. Ideas relating environmental instability and community diversity are reviewed. The distinction is made between evolutionary mechanisms, which require very long periods of time to operate, and ecological mechanisms, which operate over shorter spans of time. As part of the discussion of …

Size Structure and Intraguild Interactions between Two Ambystoma Species
… for size-structured intraguild interactions in temporary pond ecosystems between marbled salamanders (<em>Ambystoma opacum</em>) and tiger salamanders (<em>Ambystoma tigrinum</em>) using an outdoor mesocosm experiment. I hypothesized that 1) <em>A. opacum</em> survivorship and growth would be …

Comportamento reprodutivo de Phyllomedusa rohdei Mertens, 1926 (Amphibia, Anura, Hylidae), na região de Saquarema, Estado do Rio de Janeiro, Sudeste do Brasil
… of Phyllomedusa rohdei was observed in a temporary pond, located at Saquarema, Rio de Janeiro State, Brazil from July, 1999 to July, 2000. The reproductive period extended from December to February (wet season). Females were larger and heavier than males. Males spent relatively few nights …

Dispersal Behavior Of Mosquitofish (gambusia Holbrooki)
… were tested: habitat of origin (permanent vs. temporary waters), water depth (3-24 mm), and the interaction between water depth and leaf litter type (upland and wetland). Fish from a temporary pond dispersed significantly faster than fish from a permanent pond, and fish dispersed significantly …

Causes and consequences of patchy spatial distribution in male and female fairy shrimp, Eubranchipus bundyi
… and some possible effects they might have on the temporary pond community, focusing mainly on behavioral responses to environmental variables. Lab and field experiments, as well as transect data, suggest E. bundyi may be attracted to dim light and seek shade and structure within the water column …

Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
… of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf litter present because leaf species differ in the kind of habitat structure they provide and the rate at which they release nutrients into the water. Landscape quality could …

Possible Effects Of Climate Change On Induced Defenses In Tadpoles
… in the next century. Researchers predict that temporary ponds will be affected, resulting in shorter average hydroperiods (the amount of time a pond holds water). Species that live in these ponds will face increased stress due to these environmental changes, which may affect the timing of …

The effects of the invasive exotic Chinese tallow tree (Triadica sebifera) on amphibians and aquatic invertebrates
… the quantity and quality of litter inputs to ponds from those produced by a mixture of native species to that of a single invasive species. This change in litter quality may have important effects on aquatic animals because leaf litter that falls into ponds is an important source of nutrients …
