Article Abstract

Migratory species depend on a suite of interconnected sites. Threats to unprotected links in these chains of sites are driving rapid population declines of migrants around the world, yet the extent to which different parts of the annual cycle are protected remains unknown. We show that just 9% of 1451 migratory birds are adequately covered by protected areas across all stages of their annual cycle, in comparison with 45% of nonmigratory birds. This discrepancy is driven by protected area placement that does not cover the full annual cycle of migratory species, indicating that global efforts toward coordinated conservation planning for migrants are yet to bear fruit. Better-targeted investment and enhanced coordination among countries are needed to conserve migratory species throughout their migratory cycle.

Wild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of four potentially zoonotic pathogens ( spp.

Most species of migrating birds use a combination of innate vector-based orientation programs and social information to facilitate accurate navigation during their life. A number of various interspecies hybridisations have been reported in birds. The traits of parents are expressed in hybrids in typical ways which are either intermediate, combined or heterotic.

Pediculosis caused by chewing lice may pose a threat to domesticated and wild birds' health. These ectoparasites can cause pruritus, poor feather condition and do weaken hosts making them susceptible to other infections. Species of the genus Saemundssonia which are called ecomorphic head lice parasitize a wide range of aquatic birds from the family Laridae.

Migratory birds benefit from urban environments in a highly anthropized Neotropical region.

Land use change from wildlands to urban and productive environments can dramatically transform ecosystem structure and processes. Despite their structural and functional differences from wildlands, human-modified environments offer unique habitat elements for wildlife. In this study, we examined how migratory birds use urban, productive, and wildland environments of a highly anthropized region of Western Mexico known as "El Bajío".

Large-bodied pelagic sharks are key regulators of oceanic ecosystem stability, but highly impacted by severe overfishing. One such species, the shortfin mako shark (), a globally widespread, highly migratory predator, has undergone dramatic population reductions and is now Endangered (IUCN Red List), with Atlantic Ocean mako sharks in particular assessed by fishery managers as overfished and in need of urgent, improved management attention. Genomic-scale population assessments for this apex predator species have not been previously available to inform management planning; thus, we investigated the population genetics of mako sharks across the Atlantic using a bi-organelle genomics approach.
