High genetic differentiation with no evidence of hybridisation between four limpet species (Patella spp.) revealed by allozyme loci

Scientia Marina, 2007
The occurrence of hybridisation between limpet species of the genus Patella has always been a contentious issue. Although a previous allozyme study reported high differentiation and no hybridisation between Patella vulgata Linnaeus, 1758, Patella ...

Fitossociologia do componente arbóreo e florí­stica de um remanescente de cerrado sentido restrito contí­guo a áreas de agricultura na porção leste do Distrito Federal, Brasil

Heringeriana, 2014
Na década de 1970 a região leste do Distrito Federal (DF) foi ocupada por grandes cultivos  agrí­colas, restando hoje poucos remanescentes com vegetação nativa. Em um trecho de reserva, com cerca  de 85 ha de cerrado sentido restrito naquela região (15í°

Upscaling Genotyping by Amplicon Sequencing With GBAS‐GUI

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Genotyping by amplicon sequencing (GBAS) is a relatively low‐cost approach for generating genotypic data compared with established genomic methods, making it highly scalable and particularly suitable for large‐scale genetic monitoring projects.

Generation of Trichoderma harzianum with pyr4 auxotrophic marker by using the CRISPR/Cas9 system

Scientific Reports, 2021
Trichoderma harzianum is a filamentous fungus used as a biological control agent for agricultural pests. Genes of this microorganism have been studied, and their applications are patented for use in biofungicides and plant breeding strategies.

Standardizing assessment of novel methods for ecological data collection

Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2822-2828, October 2026.
Abstract Methodological advances in ecology enable more efficient data collection, yet researchers need to clearly and consistently report the ways in which these methods benefit their own research within the context of their specific needs. Here, we advocate for greater standardization and transparency when assessing new ecological data collection ...

Alternated selection mechanisms maintain adaptive diversity in different demographic scenarios of a large carnivore

BMC Evolutionary Biology, 2019
Background Different population trajectories are expected to impact the signature of neutral and adaptive processes at multiple levels, challenging the assessment of the relative roles of different microevolutionary forces.

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, Volume 168, Issue 4, Page 1210-1229, October 2026.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Phylogeographic Breaks With and Without Contemporary Barriers to Migration in the Lizard Acanthodactylus erythrurus

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Identifying phylogeographic breaks and deciphering the relative contributions of environmental extrinsic (e.g., geological barriers, ecological gradients) and organismal intrinsic (e.g., limited dispersal, reproductive incompatibilities) factors to their persistence remain challenging, especially in the absence of genomic data.
