Skeletal plasticity in response to embryonic muscular activity underlies the development and evolution of the perching digit of birds
(Nature, 2015)
Most birds have an opposable digit 1 (hallux) allowing the foot to grasp, which evolved from the
non-opposable hallux of early theropod dinosaurs. An important morphological difference with
early theropods is the twisting ...
Effects of exotic fish farms on bird communities in lake and marine ecosystems
(Springer-Verlag Berlin Heidelberg, 2013)
Salmon farming is a widespread activity around the
world, also known to promote diverse environmental effects
on aquatic ecosystems. However, information regarding the
impact of salmon farming on bird assemblages is ...
Understanding the distribution of a threatened bird at multiple levels: A hierarchical analysis of the ecological niche of the Santa Marta Bush-Tyrant (Myiotheretes pernix)
(Cooper Ornithological Soc., 2015)
An understanding of the ecological factors determining bird species’ distributions is essential for making informed
conservation decisions. These data are especially important for range-restricted species, such as the ...
Effects of vector behavior and host resistance on mistletoe aggregation
(Ecological Society of America, 2004)
t. Understanding the factors affecting parasite aggregation in natural host pop-
ulations is one of the central questions in parasite ecology. While different biological
mechanisms giving rise to aggregation have been ...
Negative impacts of a vertebrate predator on insect pollinator visitation and seed output in Chuquiraga oppositifolia, a high Andean shrub
(Springer, 2004)
Studies on plant-pollinator interactions have largely neglected the potential negative effects of the predators of pollinators on seed output, even though anti-predatory behaviour of pollinators may affect visitation ...
Edificios usados como refugios por murciélagos en un campus universitario del piedemonte llanero de Colombia
(Universidad de los Llanos, 2019-12-16)
Algunos murciélagos ocupan ambientes altamente modificados por los humanos, y en Colombia poco sabemos sobre su historia natural en ambientes urbanos. Por ello estudiamos los edificios utilizados por murciélagos como ...
