Emigration Orientation of Juvenile Pond-Breeding Amphibians in Western Massachusetts
We studied the emigration of juvenile age-class individuals of four species of pondbreeding amphibians at 14 seasonal ponds over four consecutive years in western Massachusetts. Emigration orientation of each species was non-uniform for the majority of pond-years examined. While orientation was decidedly non-uniform in most individual pond-years, combining data from successive years led to a mo...
متن کاملEmigration Timing of Juvenile Pond-Breeding Amphibians in Western Massachusetts
—Understanding the timing of movement events of pond-breeding amphibians to and from breeding and natal ponds, respectively, is essential to implementing effective conservation and monitoring strategies for this group of vertebrates. In this study, we assessed the emigration timing of newly metamorphosed juveniles of four species of pond-breeding amphibians (Ambystoma maculatum, Ambystoma opacu...
متن کاملEffects of wind-energy facilities on breeding grassland bird distributions.
The contribution of renewable energy to meet worldwide demand continues to grow. Wind energy is one of the fastest growing renewable sectors, but new wind facilities are often placed in prime wildlife habitat. Long-term studies that incorporate a rigorous statistical design to evaluate the effects of wind facilities on wildlife are rare. We conducted a before-after-control-impact (BACI) assessm...
متن کاملPost-disturbance Changes in a Desert Breeding Bird Community
--We examined breeding bird species richness, density, and community composition on a California desert riparian site in 1980 and, following construction of flood control structure and subsequent vegetation restoration, again in 1995. Both species richness and bird abundance declined markedly between 1980 and 1995. Except for turnover in locally scarce breeders, however, avian community composi...
متن کاملMigrants in tropical bird communities: the balanced breeding limitation hypothesis
Explanations for the ecological integration of migratory and non-migratory (resident) insectivorous birds in the tropics have been complicated by the paradox that arthropod abundances are low when bird abundances reach their annual peak. The breeding currency hypothesis and the nest predation hypothesis both account for this paradox by postulating that residents are held below the non-breeding ...
