An ecologically sound and participatory monitoring network for pan‐Arctic seabirds [PDF]

Conservation Biology, Volume 38, Issue 6, December 2024.
Abstract In a warming Arctic, circumpolar long‐term monitoring programs are key to advancing ecological knowledge and informing environmental policies. Calls for better involvement of Arctic peoples in all stages of the monitoring process are widespread, although such transformation of Arctic science is still in its infancy.

Field determined variation of the unsaturated hydraulic conductivity functions using simplified analysis of internal drainage experiments Variação da condutividade hidráulica do solo não saturado determinada em condições de campo utilizando análises simplificadas de experimentos de drenagem interna

Scientia Agricola, 1994
Experimentally determined values of unsaturated soil hydraulic conductivity are presented for an Alfisol of the county of Piracicaba, S.P., Brazil. Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within ...

Comparação de métodos de determinação da condutividade hidráulica em um latossolo vermelho-amarelo

Revista Brasileira de Ciência do Solo, 2011
A determinação da condutividade hidráulica como variável do conteúdo de água volumétrico, K(θ), é essencial para resolver, por exemplo, problemas de drenagem. Todavia, diferentes métodos de determinação podem produzir resultados distintos, dependendo dos

Cascading effects of climate variability on the breeding success of an edge population of an apex predator

Journal of Animal Ecology, Volume 89, Issue 11, Page 2631-2643, November 2020., 2020
The authors demostrate how climate interacts with local demography to determine population fitness and viability. The mechanistic approach taken allowed us to unravel the cascading effects of the annual fluctuations of a major climatic phenomenon over the Atlantic on the vital rates of a wild bird population, and provided the first evidence of wind as ...

Estudo comparativo entre o teste do pH e do KOH versus escore de Nugent para diagnóstico da vaginose bacteriana em gestantes Comparative study between the pH test and of the KOH versus Nugent score for diagnosis of bacterial vaginosis in pregnant women

Revista Brasileira de Ginecologia e Obstetrícia, 2012
OBJETIVO: Aquilatar a prevalência da vaginose bacteriana e comparar a acurácia dos testes do pH e do KOH com o gradiente de Nugent, método padrão-ouro, no diagnóstico da vaginose bacteriana (VB) em gestantes assintomáticas e sintomáticas de baixo risco ...

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...

Delivering the promises of trait‐based approaches to the needs of demographic approaches, and vice versa

Functional Ecology, Volume 32, Issue 6, Page 1424-1435, June 2018., 2018
Abstract Few facets of biology vary more than functional traits and life‐history traits. To explore this vast variation, functional ecologists and population ecologists have developed independent approaches that identify the mechanisms behind and consequences of trait variation.
