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

open access: yesScientia 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 ...

Multi‐decadal woodland recovery after land abandonment: environmental constraints on passive rewilding in Mediterranean landscapes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Across the Mediterranean Basin, land abandonment has opened large areas to passive rewilding, raising questions about the pace and variability of secondary succession in these landscapes and how ecological and abiotic gradients mediate vegetation recovery in post‐agricultural landscapes. Objectives This study aims to quantify long‐

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

open access: yesHeringeriana, 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°

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

open access: yesScientific 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.

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

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

open access: yesBMC 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.

Ecological effects on female bill colour explain plastic sexual dichromatism in a mutually-ornamented bird

open access: yesScientific Reports, 2021
Sex differences in ornamentation are common and, in species with conventional sex roles, are generally thought of as stable, due to stronger sexual selection on males.

Non‐native parrot species expand the trait space of avian communities by filling empty niches in urban areas

open access: yesIbis, Volume 168, Issue 3, Page 1055-1070, July 2026.
Non‐native species are one of the greatest threats to biodiversity worldwide due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non‐native species successfully establish outside their native range.

Effects of aging on the skin and gill microbiota of farmed seabass and seabream

open access: yesAnimal Microbiome, 2021
Background Important changes in microbial composition related to sexual maturation have been already reported in the gut of several vertebrates including mammals, amphibians and fish.

Genomic Variation and Population Structure of Portuguese Native Dog Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...
