Piper longiapiculatum (Piperaceae), a New Species From the Brazilian Amazon Piper longiapiculatum (Piperaceae), uma Nova Espécie da Amazônia Brasileira

Feddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT In order to address the many lacunae in Amazonian Piper taxonomy and geography, we performed a field expedition in the Serra do Divisor National Park (Acre state, Brazil), resulting in the discovery of a new species, Piper longiapiculatum, herein described and compared to morphologically similar taxa.

New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

TAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus

Plant‐Trait Syndromes and Environmental Filtering Drive Biomass Ecology in Resource‐Limited Forest Ecosystems

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Aboveground biomass (AGB) in Pakistan's forests is primarily driven by functional dominance, with soil fertility playing a secondary but significant role, while climate effects vary across forest types. Mixed forests support the highest biomass and show the strongest influence of dominant traits, whereas climate constraints are more evident in ...

Late Quaternary vegetation dynamics from central parts of the Madeira River in Brazil

Acta Botânica Brasílica, 2015
The present study reconstructs the paleovegetation of a varzea (seasonally flooded) forest in the central parts of the Madeira River floodplain in Brazil using palynological data. Forty-nine cut-bank sediment samples from the Madeira River were processed

Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Avaliação de leguminosas forrageiras sob condições de várzea parcialmente drenada

Boletim de Indústria Animal, 2014
Este estudo foi conduzido no Instituto de Zootecnia, Nova Odessa, SP, para avaliar o desempenho de 10 leguminosas cultivadas sob condições de várzea parcialmente drenada. Foram avaliadas a germinação e desenvolvimento inicial das plantas, a cobertura do solo pela vegetação e a aceitação relativa das mesmas, sob pastejo.
