Admissible nested covariance models over spheres cross time
(Springer New York LLC, 2018)
Nested covariance models, defined as linear combinations of basic covariance functions, are very popular in many branches
of applied statistics, and in particular in geostatistics. A notorious limit of nested models is ...
Cavity characteristics, but not habitat, influence nest survival of cavity-nesting birds along a gradient of human impact in the subtropical Atlantic Forest
(Elsevier, 2015-04)
Cavity-nesting vertebrates are an important component of biodiversity in tropical and subtropical forests, but their persistence will increasingly depend on remnant trees in logged forest and agricultural areas. To identify ...
Human waste used as nesting material affects nest cooling in the clay-colored thrush
(2021-09-01)
The internal temperature of nests largely depends on the materials used in their construction because the characteristics of each material affect the isolation of nest walls. In urban environments, the availability of
natural ...
Statistical Models for Small Area Estimation
(CIMAT, 2014)
Multi-level integrated health management model for empty nest elderly people's to strengthen their lives
The old-age “empty-nest” family in China has become more prevalent in the recent past. This research focused on strengthening the lives of empty nests elderly people during their distress using an appropriate instrumental ...
Thermal Characteristics of Polybia scutellaris Nests (Hymenoptera: Vespidae) Using Computational Fluid Dynamics: A Possible Adaptation to Tropical Climates
(CALIFORNIA STATE UNIV, 2011)
Polybia scutellaris constructs huge nests characterized by numerous spinal projections on the surface. We investigated the thermal characteristics of P scutellaris nests in order to determine whether their nest temperature ...
Influence of logging on nest density and nesting microsites of cavity-nesting birds in the subtropical forests of the Andes
(Oxford University Press, 2021-06)
Birds select nesting sites with certain characteristics associated with tree age and species that help to prevent or reduce the risk of clutch loss due to predation or unfavourable weather conditions. Logging may reduce ...
Nest Survival and Predation in Blue-Fronted Parrots Amazona aestiva: Effects of Nesting Behaviour and Cavity Characteristics
(Nederlandse Ornithologische Unie, 2016-10)
In this study we analyse factors affecting nest survival in Blue-fronted Parrots Amazona aestiva breeding in the Chaco region of northern Argentina. We combined temporal and environmental variables in order to determine ...
Percepção dos predadores de ninhos e estratégias anti-predação numa comunidade de aves da Mata Atlântica do estado de São Paulo
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2019-04-25)
The main cause of annual variations in bird’s reproductive output is the failure of nests resulted from predation. Eggs exposed in open nests, usually have a wide range of colorations, and may coincide with the color of ...
Nest site selection and flying capacity of neotropical wasp Angiopolybia pallens (Hymenoptera: Vespidae) in the Atlantic Rain Forest, Bahia State, Brazil
(2006-06-07)
In order to evaluate the flying capacity and nest site selection of Angiopolybia pallens (Lepeletier, 1836), we made 17 incursions (136 hours of sample efforts) in Atlantic Rain Forest environments in Bahia state. Our data ...
