TL;DR: This paper presents a meta-analyses of hibernation and dispersal patterns in colonies using a probabilistic approach, aiming at determining the patterns of dispersal and community relationships during the hibernation period.

TL;DR: Temporal patterns of anuran reproduction fall into two broad categories: prolonged breeding and explosive breeding, and many aspects of vocal behaviour and chorus organization can be viewed as consequences of intrasexual competition.

TL;DR: The Contracting States recognise that wild fauna and flora in their many beautiful and varied forms are an irreplaceable part of the natural systems of the earth which must be protected for this and the generations to come.
Abstract: The Contracting States recognising that wild fauna and flora in their many beautiful and varied forms are an irreplaceable part of the natural systems of the earth which must be protected for this and the generations to come; conscious of the ever-growing value of wild fauna and flora from aesthetic, scientific, cultural, recreational and economic points of view; recognizing that peoples and States are and should be the best protectors of their own wild fauna and flora; recognizing, in addition, that international co-operation is essential for the protection of certain species of wild fauna and flora against over-exploitation through international trade; convinced of the urgency of taking appropriate measures to this end, have agreed as follows:

TL;DR: It is suggested that many amphibian populations may be unable to recolonize areas after local extinction, due to the physiological constraints, relatively low mobility, and site fidelity of amphibians.
Abstract: Extinctions are normal biological phenomena Both mass extinctions in geological time and local extinc- tions in ecological time are well documented, but rates of extinction have increased in recentyears-especially in ver- tebrates, including amphibians-as illustrated by recent re- ports of their population declines and range reductions. We suggest that long-term population data are necessary for rig- orously evaluating the significance of the amphibian de- clines. Due to the physiological constraints, relatively low mobility, and site fidelity of amphibians, we suggest that many amphibian populations may be unable to recolonize areas after local extinction.
