Thermal Ecology of a Central Anatolian Population of <i>Ophisops elegans</i>: Insights From Field Measurements and Microclimate Modeling. [PDF]

Ecol Evol
Thermal ecology and behavior of O. elegans were examined with related morphological and environmental parameters. Substrate and air temperatures are the main factors influencing thermal biology. Thermoregulatory efficiency values indicate that O. elegans is an effective thermoregulator.

Effects of Regional Weather and Agricultural Practices on the Nest Survival of Northern Lapwings in France. [PDF]

Ecol Evol
This study monitored nests of lapwings with cameras and weekly visits at inland sites in eastern France, and at coastal sites in northern France. About a third of nests failed; the main causes of failure were agricultural equipment (11%), abandonment (8.2%), and depredation (7.5%). Estimates of nest survival for a 27‐day incubation were 66% and 59% for

Reliability and Validity of the Italian Translation of the Updated Version of the Pressure Ulcer Knowledge Assessment Tool (PUKAT 2.0). [PDF]

Int Wound J
ABSTRACT The study aimed to translate the PUKAT 2.0 tool from English to Italian. This was an adaptation and validation study; the validity of the Italian version was determined through content validity, item validity and construct validity. The reliability of the instrument was assessed by conducting a test–retest analysis on a sample of 62 nurses ...

A mechanistic model of endotherm hibernation applied to the endangered mountain pygmy possum under climate change. [PDF]

Ecology
Abstract Hibernation is an important strategy used by many endotherms to conserve energy and water. Global warming is changing species' phenology and hibernation patterns, but whether such changes are beneficial or harmful depends on the species' life history traits, physiology, morphology, and behavior.

Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment. [PDF]

New Phytol
Summary Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptors signals the availability of sunlight for photosynthesis.

Gene Flow and Vertical Stratification of Pollination in the Bat-Pollinated Liana <i>Marcgravia longifolia</i>. [PDF]

Ecol Evol
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Microclimate refugia shape microclimatic niches and predict individual variability in post-breeding migration in a partially migratory species. [PDF]

J Anim Ecol
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

Local Adaptation Drives Leaf Thermoregulation in Tropical Rainforest Trees. [PDF]

Glob Chang Biol
We tested whether tropical rainforest trees adjust their leaf traits and resulting leaf temperatures across their distributions within the Australian Wet Tropics. Using field measurements from across a temperature gradient, we modeled leaf–air temperature differences and calculated heat safety margins for three species.

Microclimate variability impacts the coexistence of highland and lowland ectotherms. [PDF]

J Anim Ecol
Our paper is an original attempt to use mechanistic models to explain the patterns of species coexistence along an environmental gradient. It is novel both in its methodological approach to the topic as well as through the obtained results. Abstract Understanding differences in life‐history outcomes under variable abiotic conditions is essential for ...

UV RESISTANCE LOCUS 8 signalling enhances photosynthetic resilience to herbicide-induced damage in Arabidopsis thaliana. [PDF]

New Phytol
Summary Perception of low irradiance ultraviolet B (UV‐B) light (280–315 nm) by the UV RESISTANCE LOCUS 8 (UVR8) photoreceptor initiates signalling pathways that enhance plant defences to UV‐B damage, mitigating the effects of higher photon irradiances.
