MANILA (Reuters) - The Philippines on Sunday warned citizens not to kill or poach migratory birds that usually fly in from China, the possible source of a virus that triggered the Southeast Asian n

The Arctic is warming faster than any other part of the world, and its ecosystems are changing quickly, with shifts in the timing of insect hatches, plant growth and more.

International elephant research organization, Save The Elephants, said Thursday an ambitious new report identifying some of Kenya's most important wildlife migratory corridors will help close the g

This study investigates how noise reduction (road closure) mitigates the effect of traffic noise on the acoustic communication of the Eastern wood pewee (Contopus virens) (EAWP), a suboscine passerine. Songs were passively recorded at sites where the traffic pattern of the nearest road was either relatively constant or reduced on a weekly basis during a 36 h road closure.

Semipalmated Sandpiper (Calidris pusilla) populations have undergone significant declines at core nonbreeding sites in northeastern South America. Breeding populations have also declined in the eastern North American Arctic, but appear to be stable or increasing in the central and western Arctic.

Onset of early summer has triggered early return of migratory birds from the region.

A thorough understanding of movement patterns of a species is critical for designing effective conservation and management initiatives. However, generating such information for large marine vertebrates is challenging, as they typically move over long distances, live in concealing environments, are logistically difficult to capture and, as upper-trophic predators, are naturally low in abundance. Large-bodied, broadly distributed tropical shark typically restricted to coastal and shelf habitats, the great hammerhead shark Sphyrna mokarran epitomizes such challenges.

We mapped the inferred long-distance migrations of four species of Amazonian goliath catfishes (Brachyplatystoma rousseauxii, B. platynemum, B. juruense and B. vaillantii) based on the presence of individuals with mature gonads and conducted statistical analysis of the expected long-distance downstream migrations of their larvae and juveniles.

Determining location and timing of ontogenetic shifts in the habitat use of highly migratory species, along with possible intrapopulation variation in these shifts, is essential for understanding mechanisms driving alternate life histories and assessing overall population trends. Measuring variations in multi-year habitat-use patterns is especially difficult for remote oceanic species.
