Linking rivers, barrages and fish migration

Regulating fluvial systems by dams, barrages and construction of inter-basin link canals, has severe impacts on fish populations across the world’s rivers. In India, all major fluvial systems are interrupted by a series of barriers. This includes small weirs to large dams and salt-water barriers preventing saline incursion to the …

Evidence of suboscine song plasticity in response to traffic noise fluctuations and temporary road closures

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 …

Migratory connectivity of Semipalmated Sandpipers and implications for conservation

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. To identify vulnerable populations and sites, we documented the …

Migratory birds prepare for early return as temperatures soar

Onset of early summer has triggered early return of migratory birds from the region. Birdwatchers have observed that the winged visitors have begun to assemble at Ganga Barrage here in preparation for their flight owing to the sudden rise in temperature. Met officials said northern parts of the country are …

Philopatry and regional connectivity of the Great Hammerhead Shark, Sphyrna mokarran in the U.S. and Bahamas

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 …

Goliath catfish spawning in the far western Amazon confirmed by the distribution of mature adults, drifting larvae and migrating juveniles

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.

Intrapopulation variability in the timing of ontogenetichabitat shifts in sea turtles revealed using d15N valuesfrom bone growth rings

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. …
