“A GENTE NÃO PESCA, A GENTE É A PESCA”

Revista Gênero
A atuação das mulheres na pesca artesanal é invisibilizada, sendo necessário valorizar os seus saberes e práticas. O objetivo foi descrever o olhar das pescadoras acerca do ambiente pesqueiro a partir das suas trajetórias socioambientais na Reserva Extrativista Acaú-Goiana. O estudo foi desenvolvido com pescadoras beneficiárias do território, aplicando

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

Oikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

ECONOMIA CIRCULAR E RESÍDUO DE PESCADO

Revista Brasileira de Ciências Ambientais, 2020
O conceito de economia circular propõe uma profunda transformação que reduz o impacto das atividades humanas no meio ambiente. Os resíduos da indústria pesqueira são uma importante fonte de contaminação ambiental e perda de nutrientes.

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

Integrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.

Influência de fatores abióticos sobre a maturação dos ovários de Pimelodus maculatus Lac. 1803 (Pisces, Siluroidei)

Boletim do Instituto de Pesca, 2018
O presente trabalho teve o propósito de estabelecer correlações entre alguns fatores abióticos e a maturação dos ovários de P. maculatus, expressa por valores médios do í­­ndice gônado somático (IGS). Foi encontrada uma correlação positiva entre o IGS e

Muralismo como encargo participativo: Holografía de lo (in)visible en comunidades a’i cofán de la selva colombiana

Anthropology of Consciousness, EarlyView.
ABSTRACT When mural art in indigenous communities is commissioned as a participatory project, several methodological, epistemological, and aesthetic questions arise. This text proposes a horizontal and investigative approach to what we can simply call ‘muralism in the A'i Cofán community context,’ not as significant works executed in communities, but ...

Maturation curve of the ovary of Pimelodus maculatus Lac. (Siluroidei, Teleostei)

Boletim do Instituto de Pesca, 2018
O presente trabalho tem como objetivo pesquisar, paralelamente ao estudo macro e microscópico dos estádios gonadais e dentro da metodologia mais objetiva possí­­vel, variáveis que, dependente da evolução gonadal, chegassem a constituir função da mesma e
