Global Polynomial Kernel Hazard Estimation
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Estadística, 2015-07-01)
This paper introduces a new bias reducing method for kernel hazard estimation. The method is called global polynomial adjustment (GPA). It is a global correction which is applicable to any kernel hazard estimator. The estimator ...
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 ...
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
(Elsevier, 2020)
Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ...
Geographic variation in the repeatability of a personality trait
(OXFORD UNIV PRESS INC, 2010-08-06)
Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is
revealing the adaptive significance of personalities, although the mechanisms driving ...

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 ...
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 ...
