Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

open access: yesJournal of Zoology, EarlyView.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

open access: yesMedical and Veterinary Entomology, EarlyView.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

Morphophysiological response of Cerrado plants to filter cake biochar application

open access: yes, 2023
Some native species of the Cerrado have great ecological and economic potential. An alternative that aims to contribute to the good performance of post-planting plants is the incorporation of biochar into the soil. The objective of this work was to evaluate the effect of filter cake biochar as a soil conditioner and its influence on the growth and ...

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, EarlyView.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

open access: yesPlant Biology, EarlyView.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

open access: yesPlant Biology, EarlyView.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Effects of post‐fire on seed germination and seedling recruitment of a generalist savanna woody species

open access: yesPlant Biology, EarlyView.
This study evaluated germination, recruitment, and early seedling growth of Vochysia tucanorum through a field experiment based on direct seed deposition into the soil under natural conditions, simulating post‐dispersal environments in burned and unburned areas.

How are we choosing species for direct seeding restoration in megadiverse neotropical landscapes? Recommendations from projects implemented in Brazil

open access: yesRestoration Ecology, EarlyView.
Direct seeding for ecological restoration is a cost‐effective and scalable method, but its effectiveness largely relies on choosing the appropriate species. Understanding the criteria used to select species is critical for optimizing restoration outcomes, especially in the face of limited resources and ongoing environmental changes.
