Considerações sobre o conceito de temperatura e de temperatura absoluta [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2006
Discute-se o conceito de temperatura que emerge da ação de contato, e a conveniência de torná-lo menos abstrato levando em conta a quantidade de matéria envolvida. Mostra-se que o conceito de 'energia térmica molar', numericamente igual ao produto da constante dos gases pela temperatura absoluta, preenche aquele fim, expressando o conteúdo cinético da ...

How vulnerable are amphibians to climate change? A mechanistic perspective

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...

The distribution, abundance, and ecology of larval tunas from the entrance to the Gulf of California [PDF]

open access: yes, 1970
ENGLISH: This study is based on collections of larvae of Thunnus albacares, Euthynnus llneatus, and Auxis sp. obtained from surface and oblique net tows made during seven cruises, each along a comparable track in the entrance of the Gulf of California ...

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

open access: yesJournal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...

Some aspects of upwelling in the Gulf of Panama [PDF]

open access: yes, 1958
ENGLISH: Strong coastal upwelling occurs in the Gulf of Panama regularly each year during the season, from about January through April, when strong northerly winds are blowing offshore. Because of the evident importance of upwelling to the ecology of the

Universal restrictions to the conversion of heat into work derived from the analysis of the Nernst theorem as a uniform limit

open access: yes, 2003
We revisit the relationship between the Nernst theorem and the Kelvin-Planck statement of the second law. We propose that the exchange of entropy uniformly vanishes as the temperature goes to zero. The analysis of this assumption shows that is equivalent

A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.
