Structure of aquatic vegetation of a large lake, western border of the Brazilian Pantanal

open access: yesBrazilian Journal of Biology
Studies on Neotropical aquatic macrophytes have increased in recent decades, however species richness in wetlands of South America is far from being fully known. In addition, studies having an ecological approach are scarce in the Pantanal.

Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil

open access: yesNordic Journal of Botany, EarlyView.
Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

Tell me where you flow and I will tell you who you are: basin context shapes the insect fauna of small tributaries

open access: yesOikos, EarlyView.
The traditional view of river basins as linear corridors has led to numerous studies examining the effects of stream size on aquatic communities. However, similar‐sized streams may harbor distinct faunal assemblages depending on their spatial context within the basin. Headwater tributaries (HTs) that flow into small streams, in the periphery of basins,

Calibrating p‐values in ecology: a practical framework for integrating prior plausibility into statistical inference

open access: yesOikos, EarlyView.
Misinterpretation of p‐values, coupled with insufficient consideration of the prior plausibility of ecological hypotheses, leads to overconfident and often unreliable inference in ecological research. To address this issue, we present a methodological framework for p‐value calibration that reinterprets conventional p‐values through minimum Bayes ...

Innovations in polysaccharide‐based hydrogels in sustainable agriculture

open access: yesPolymer International, EarlyView.
Polysaccharide‐based hydrogels are promising in sustainable agriculture, as these natural polymers have the ability to absorb water and nutrients and release them gradually in the soil, in addition to ensuring biodegradability and lower cost. However, some challenges still need to be overcome.

Open letter: Brazil at a crossroads—Protecting peatlands is essential for post‐COP30 climate leadership

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
This Open Letter highlights peatlands as critical yet overlooked ecosystems in Brazil's climate and biodiversity policies. By translating scientific evidence into clear, actionable priorities for policymakers, it supports more accurate climate reporting, effective mitigation strategies, and improved land‐use governance.
