The Role of Elevation, Connectivity and Land Cover on Migratory and Non‐Migratory Fish Communities in an Amazonian Riverine System

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Dams and deforestation are key drivers of freshwater biodiversity loss in the Amazon, as they alter river connectivity, water quality and habitat structure. This study investigates how connectivity (Reach Connectivity Index—RCI), elevation and natural land cover influence the diversity and composition of fish assemblages in a highly fragmented

A new species from an inselberg in the Brazilian Atlantic forest: Stachytarpheta forzzae (Verbenaceae), supported by morphological, palynological and anatomical evidence

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
We describe Stachytarpheta forzzae, a new species from an inselberg located in the municipality of Guaratinga, state of Bahia, within the Brazilian Atlantic forest. Morphologically, it resembles S. sprucei, the only other species of the genus known to inhabit inselbergs.

HOWLish: a CNN for automated wolf howl detection

Remote Sensing in Ecology and Conservation, Volume 12, Issue 1, Page 58-70, February 2026.
Automated detection of wolf howls presents a great opportunity for large‐scale passive acoustic monitoring of wolf populations. Here we present HOWLish, a CNN trained for automated wolf howl detection, based on thousands of hours of soundscapes recorded in the wild.

Importance and spatial patterns of invisible fisheries in Amazonian clear‐water rivers as revealed by fisher knowledge and collaboration

Conservation Biology, Volume 40, Issue 1, February 2026.
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Avaliação do risco de extinção do gato-maracajá Leopardus wiedii (Schinz, 1821) no Brasil

Biodiversidade Brasileira, 2013
Leopardus wiedii possui uma distribuição ampla no Brasil, com exceção do Ceará e sul do Rio Grande do Sul. Apesar disso, o tamanho populacional efetivo calculado é de cerca de 4.700 indivíduos no território brasileiro. Estima-se que nos próximos 15 anos (

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Avaliação do risco de extinção do gato-do-mato Leopardus tigrinus no Brasil

Biodiversidade Brasileira, 2013
Leopardus tigrinus tem ocorrência ampla no Brasil, embora seja conhecido de poucos registros no bioma Amazônico. A população desta espécie foi calculada utilizando-se uma área de remanescentes de 1.834.967 km2. A população efetiva estimada, de acordo com

Do emotions influence the motivations and preferences of keepers of stingless bees?

Journal of Ethnobiology and Ethnomedicine, 2018
Background According to the biophilia hypothesis, an emotional affiliation with nature has been inherited during human biocultural evolution. Research on beekeeping can contribute to the scientific understanding of the influence of emotions in the human ...
