Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna. [PDF]

Conserv Biol
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

A VARIABILIDADE AMBIENTAL INFLUENCIA A COMPOSIÇÃO E BIOMASSA FITOPLANCTÔNICA DE UM RESERVATÓRIO NEOTROPICAL

Oecologia Australis, 2021
Phytoplankton is an important model of the aquatic environments functioning, responding directly to environmental variability in space and time. Therefore, represents an excellent tool for the monitoring of reservoirs, which comprise highly heterogeneous ecosystems longitudinally, influencing the structure and distribution of phytoplankton species. The

Evaluating models of expert judgment to inform assessment of ecosystem viability and collapse. [PDF]

Conserv Biol
Abstract Expert judgment underpins assessment of threatened ecosystems. However, experts are often narrowly defined, and variability in their judgments may be substantial. Models built from structured elicitation with large diverse expert panels can contribute to more consistent and transparent decision‐making.

Variabilidade produtiva e agrupamentos de colheitas de abobrinha italiana cultivada em ambiente protegido [PDF]

Ciência Rural, 2010
No planejamento experimental, a variabilidade entre parcelas pode alterar as estimativas dos tamanhos de parcela e de amostra, além do número de repetições e definição do delineamento experimental. Para verificar a interferência da variabilidade das estimativas de valores usados na determinação do tamanho de parcelas com diferentes números de plantas e

Ambientes restauradores no trânsito: variabilidade da freqüência cardíaca e tempo de reação

Revista de Ciências Humanas, 2011
Neste trabalho investigou-se a aplicação da variabilidade da freqüência cardíaca (VFC) para a monitorização e gravação dos estados de excitação autonômica de um motorista em uma viagem interestadual de 725 km. O sinal de VFC é usado como uma ferramenta para a avaliação do sistema nervoso no controle da freqüência cardíaca.
