Do female ornaments indicate quality in eider ducks?
The fitness consequences of female ornamentation remain little studied and the results are often contradictory. Female ornamentation may be an artefact of a genetic correlation with male ornamentation, but this possibility can be disregarded if the ornament only occurs in females. Female-specific white wing bars in eiders (Somateria mollissima) have been suggested to indicate individual quality...
متن کاملThe influence of breeding phenology on the genetic structure of four pond‐breeding salamanders
Understanding metapopulation dynamics requires knowledge about local population dynamics and movement in both space and time. Most genetic metapopulation studies use one or two study species across the same landscape to infer population dynamics; however, using multiple co-occurring species allows for testing of hypotheses related to different life history strategies. We used genetic data to st...
متن کاملCharacteristics of Ponds Used by Breeding Mottled Ducks on the Chenier Plain of the Texas Gulf Coast
Mottled ducks Anas fulvigula are nonmigratory and primarily depend on habitats associated with coastal marshes of the Gulf Coast for their entire life cycle. Much of remaining available coastal marsh habitats of the Texas Gulf Coast are managed by state and federal agencies. The Texas Gulf Coast breeding population of mottled ducks has recently declined dramatically. To aid in development of ma...
متن کاملShellfishing, eider ducks and nature conservation on the Wash: questions raised by a fractured partnership
This article examines the state of current approaches to the governance of common pool resources (CPRs), the impacts of the recent emergence of the partnership paradigm and the consequences for the management of CPRs. These issues are explored through a case study of the Wash European Marine Site partnership, where a Public Inquiry recently upheld the refusal of the conservation agency to grant...
متن کاملUpland Habitat Quality and Historic Landscape Composition Influence Genetic Variation of a Pond-Breeding Salamander
Understanding the temporal and spatial scale at which habitat alteration impacts populations is important for conservation and management. Amphibians have declined more than other vertebrates, and pond-breeding species are particularly susceptible to habitat loss and fragmentation because they have terrestrial and aquatic life stages. One approach to management of pond-breeding species is prote...
