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.

O IMPACTO DA VEGETAÇÃO URBANA NO CONFORTO TÉRMICO NA ESCALA LOCAL DO DISTRITO FEDERAL – DF.

Mix Sustentável, 2020
Em um mundo cada vez mais urbano, a vegetação mostra-se como uma das principais contribuintes para o aumento do conforto térmico no microclima. O objetivo deste estudo é analisar o impacto do acréscimo de vegetação urbana no conforto térmico na escala ...

aligardner/microclima: Ilyamaclean/microclima

, 2021
The functions in the microclima package contain tools for modelling the mechanistic processes that govern fine-scale variation in temperature. It includes tools for determining local variation in temperature arising from variation in radiation, wind ...

Indicatori ambientali per la valutazione degli immobili [PDF]

Territorio Italia, 2015
La valutazione degli immobili a fini fiscali si è basata, storicamente, su criteri di tipo edilizio-urbanistico, rispondenti prevalentemente a logiche di attrattività commerciale dell’unità immobiliare da stimare, dell’edificio a cui essa appartiene e ...

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.

Estimativa da duração do período de molhamento por orvalho em um ecossistema cacau Estimate of the duration of the wetness period by dew in a cocoa ecosystem

Revista Brasileira de Engenharia Agrícola e Ambiental, 2009
O objetivo deste trabalho foi estimar a duração do período de molhamento por orvalho (DPM), entre 18 e 06 h, utilizando-se dois modelos empíricos: a) o do número de horas com umidade relativa > a 97% (NHUR > 97%) e b) o da depressão do ponto de orvalho <

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.
