Migratory Connectivity and the Conservation of Migratory Animals
Migration is the repeated seasonal movement to and from a breeding area. The linking of individuals or populations of a given species within its range, including its breeding, migration, and wintering areas, is known as migratory connectivity. In this Article, we discuss how new technologies and approaches are enhancing our knowledge of migratory connectivity, which in turn can improve our legal and policy approaches to the conservation of migratory animals. Advances in studying and documenting migratory connectivity require new approaches to the design and implementation of both domestic and international conservation efforts. Understanding migratory connectivity of different populations of species between specific geographic locations can also help build “social connectivity” for conservation—the cultural, educational, economic, and institutional linkages between these same locations that are a necessary foundation for effective and sustainable conservation efforts.
The International Convention for the Regulation of Whaling
Since the moratorium on commercial whaling decided by the International Whaling Commission (IWC) in 1982, its activity has been characterised by measures which aim at protecting whales instead of encouraging their exploitation. After recalling some of the features of the 1946 International Convention on the Regulation of Whaling (ICRW) and the problems concerning its implementation, the article deals with some recent developments in the framework of the IWC's practice. It illustrates the different positions of the IWC's members who want to whale the abundant species and of those who want to ban whaling for good. Finally, the article contains some tentative comments about this difference of opinion and its consequences.
Historical biogeography of a new antitropical clade of temperate freshwater fishes
Any discovery of new biogeographical pattern in landlocked animals may challenge hypotheses that account for the evolution of intercontinental faunas. In this study, we examined the evolutionary origin and historical biogeography of temperate, freshwater perch‐like fishes within a molecular phylogenetic framework.
