To multicellularity and back again: Description of two new coccoid genera (Portococcus gen. nov. and Pseudanabaenococcus gen. nov.) in the basal “filamentous” order Pseudanabaenales, Cyanobacteria

open access: yesJournal of Phycology, Volume 62, Issue 1, Page 234-255, February 2026.
Abstract Despite recent efforts in taxonomic revision of phylogenetically basal photosynthetic cyanobacteria, cryptic diversity and recurrence of simple plesiomorphic morphotypes has continued to appear in phylogenies with poorly characterized “Synechococcus” and “Pseudanabaena” strains.

Plântulas de girassol sob condições de estresse salino suplementadas com algas marinhas

open access: yesRevista Verde de Agroecologia e Desenvolvimento Sustentável, 2022
A irrigação é utilizada como estratégia de manejo em muitas regiões no mundo. Porém, devido às características de salinidade do semiárido, essa medida tem se tornado cada vez mais difícil em virtude da escassez de água de boa qualidade e com baixos teores de sais.

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

open access: yesJournal of Fish Biology, Volume 108, Issue 1, Page 103-117, January 2026.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

POLISSACARÍDEOS EXTRAÍDOS DE ALGAS MARINHAS E SUAS APLICAÇÕES BIOTECNOLÓGICAS: UMA REVISÃO

open access: yesRevista Brasileira de Inovação Tecnológica em Saúde - ISSN:2236-1103, 2015
A biodiversidade marinha brasileira tem sido reconhecida por ser fonte de compostos com propriedades biológicas diversas. As algas marinhas são consideradas fontes valiosas de diversos compostos bioativos, entre eles os polissacarídeos. Os principais polissacarídeos conhecidos de algas marinhas são carragenanas, agaranas e alginatos, mas também são ...

Scaling the effects of size and temperature on animal consumption rates from individuals to populations in a subtropical reef fish

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3385-3395, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Measuring how temperature and body size drive individual consumption rates is fundamental to predict how climate change might shape population‐level consumption pressure. Yet, such measurements remain rare.

Effect of proteins from the red seaweed Hypnea musciformis (Wulfen) Lamouroux on the growth of human pathogen yeasts

open access: yesBrazilian Archives of Biology and Technology, 2006
A protein fraction, rich in lectin, obtained from the red seaweed Hypnea musciformis by precipitation with ammonium sulfate (F40/70) was screened for chitinase and beta-1,3-glucanase activity and assessed for antifungal potential against the human ...

Decapod Biodiversity Hotspots and Environmental Drivers: A Macroecological Approach About Bycatch Species in Brazil

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim To investigate the spatial patterns of species richness (SR), phylogenetic diversity (PD) and phylogenetic endemism (PE) in bycatch decapod crustaceans along the Brazilian Exclusive Economic Zone and to assess the influence of environmental variables and trawling effort on these diversity indices. Location Brazilian Exclusive Economic Zone.

Neoichnology and sediment distribution in tidal flats of the mud‐dominated mesotidal Mira River estuary (Portugal)

open access: yesSedimentology, Volume 72, Issue 7, Page 2201-2238, December 2025.
ABSTRACT Invertebrate burrow morphologies and distributions are presented for the tidal flats of the middle and lower reaches of the tide‐influenced (mesotidal), mud‐dominated Mira River estuary (SW Portugal) as an analogue for interpreting the ichnology of palaeoestuarine successions.
