Sequential testing of complementary hypotheses about population density

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1228-1238, June 2025.
Abstract Making inferences about population density is paramount in ecology and pest management for decision‐makers who often seek to determine how a population compares to a pre‐established static or dynamic threshold through sampling or monitoring. Sequential data analysis is appealing for monitoring and decision making as it is more cost‐efficient ...

Accurate estimation of photosynthetic available radiation from multispectral downwelling irradiance profiles

Limnology and Oceanography: Methods, Volume 23, Issue 4, Page 261-272, April 2025.
Abstract Photosynthetic available radiation (PAR) is the light usable by photosynthetic organisms. Photosynthetic available radiation measurements at depth are required to quantify the light availability for primary production. Direct PAR measurements may be measured with full‐spectrum quantum sensors for the range 400 to 700 nm.

Emergent Relationships Between the Functional Diversity of Marine Planktonic Copepods and Ecosystem Functioning in the Global Ocean

Global Change Biology, Volume 31, Issue 3, March 2025.
We evaluate how the diversity and functional traits of copepods—tiny crustaceans that constitute the majority of marine zooplankton—relate to key processes in the oceans such as the production of plankton biomass and how it sinks at depth. The study found that a few dominant copepod species disproportionately shape these processes.

Simulating the efficacy of wolf–dog hybridization management with individual‐based modeling

Conservation Biology, Volume 39, Issue 1, February 2025.
In the photo, an introgressed adult wolf–dog in the Northern Apennines, Italy, not far from the city of Bologna. Part of a research program, this male has been sterilized and released back in its own pack with a Global Positioning Collar. Abstract Introgressive hybridization between wolves and dogs is a conservation concern due to its potentially ...

Dispersão de amostras de latossolo vermelho eutroférrico influenciadas por pré-tratamento para oxidação da matéria orgânica e pelo tipo de agitação mecânica Dispersion of oxisol samples as influenced by pretreatment for organic matter oxidation and by type of mechanical agitation

Revista Brasileira de Ciência do Solo, 2008
A dispersão de amostras de Latossolos oxídicos pode ser mais difícil devido a microagregados de alta estabilidade, que nem sempre são totalmente desfeitos pela dispersão química e mecânica.
