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

Brazilian 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

Nordic 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

Oikos, 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

Oikos, 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

Polymer 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.
