Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

Assessing Conflict Potential Between Birds and Small‐Scale Fisheries in Lake Titicaca
ABSTRACT Globally, fisheries bycatch constitutes a threat to aquatic birds. However, while the threat is global, the threat from bycatch in inland fisheries, and from artisanal or small‐scale fishing, is particularly understudied. Here, we present the first attempt to map the vulnerability of birds to fisheries bycatch, and the conflict potential ...
