Altitudinal ranging of the Guizhou golden monkey (Rhinopithecus brelichi): Patterns of habitat selection and habitat use

open access: yesGlobal Ecology and Conservation, 2018
Between September 2011 and August 2013, we studied patterns of habitat selection and habitat use in the Guizhou golden monkey (Rhinopithecus brelichi) at Fanjingshan National Nature Reserve, China.

Pearl's causality for integrating ecological datasets: A case study on Myricaria germanica in northern Italy

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...

Distribución altitudinal y diversidad de Hemiparasitas y Parasitas del orden santalales en el santuario de fauna y flora de Iguaque Boyacá (Colombia)

open access: yesActa Biológica Colombiana, 1995
The altitudinal distribution of 10 species of hemiparasitic and parasitic plants from 4 families to the Santalalean order has been studied along a transect of 9 Km from Villa de Leiva-Arcabuco road to San Pedro de Iguaque lagoon.

Plastic Responses Contribute to Explaining Altitudinal and Temporal Variation in Potential Flower Longevity in High Andean Rhodolirion montanum.

open access: yesPLoS ONE, 2016
The tendency for flower longevity to increase with altitude is believed by many alpine ecologists to play an important role in compensating for low pollination rates at high altitudes due to cold and variable weather conditions.

Altitudinal variation in body size in the Rice Frog (Rana limnocharis) in southwestern China

open access: yesActa Herpetologica, 2012
Bergmann’s rule states that, within species of endotherms, individuals tend to be larger in cooler environments, and has been reputed to apply to some ectotherms including amphibians.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Do Shapes of Altitudinal Species Richness Gradients Depend on the Vertical Range Studied? The Case of the Himalayas

open access: yesDiversity
We analyzed elevational species richness gradients (“decline”, “increase”, “unimodal”, or “bimodal”) in the Himalayan range using data from 157 publications covering both plants and animals.

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.
