Land use history and environmental filtering drive taxonomic and functional diversity in Atlantic Rainforest fragments.

The Brazilian Atlantic Rainforest is a fragmented biodiversity hotspot where anthropogenic and environmental drivers shape species composition, abundance, and dimensions of tree diversity. This study addresses how anthropogenic disturbance and edaphoclimatic and topographic environmental factors influence taxonomic and functional diversity in Atlantic Rainforest. We used forest inventory data from 136 plots across nine fragments with different land-use histories.

Geochemical dynamics of coastal environments with shrimp farming activities in southern Bahia, Brazil.

The accelerated growth of shrimp farming has led to an increased influx of organic and inorganic pollutants into water bodies, posing a threat to water quality, biodiversity, and human health. This study aimed to assess the impact of shrimp farming activities by analyzing the physical and geochemical variables of water and sediment associated with shrimp farming in Valença, Bahia. Samples were collected in triplicate, including controls, for a total of 10 samples analyzed.

Large-sized trees and altitude drive aboveground carbon stock in Brazilian Atlantic Cloud Forests: An approach based on carbon hyperdominant taxa.

Research about patterns of aboveground carbon stock (AGC) across different tropical forest types is central to climate change mitigation efforts. However, the aboveground carbon stock (AGC) quantification for Brazilian cloud forest ecosystems along the altitudinal gradient is still scarce. We aimed to evaluate the effects of abiotic and biotic on AGC and the AGC distribution between species and families of tree communities along an altitudinal Brazilian Atlantic cloud forest gradient of the Mantiqueira Mountain Range, Southeastern Brazil.

Unveiling the unknown diversity of planktonic green algae (Chlorophyta) in urban ponds in the semiarid region of Northeastern Brazil.

This study examined the taxonomic composition and ecological aspects of planktonic green algae (Chlorophyta) in four urban ponds (Parque da Lagoa, Lagoa Grande, Laguneville, and Pindoba) in Feira de Santana, Bahia State, Brazil. We analyzed 96 samples collected bimonthly in 2022 and identified 54 taxa, with the majority (42) classified as uncommon or sporadic. The most common species were Monoraphidium circinale and Lemmermannia komarekii, found in 100% and 95.

Multiple drivers influence tree species diversity and above-ground carbon stock in second-growth Atlantic forests: Implications for passive restoration.

Second-growth forests (SGF) are critical components for limiting biodiversity loss and climate change mitigation. However, these forests were established after anthropic disturbances such as land use for planting, and in highly human-modified landscapes. These interventions can decrease the ability of biological communities to recover naturally, and it is necessary to understand how multiple drivers, from local scale to landscape scale influence the diversity and carbon stock of these forests in natural regeneration.

Species composition, diversity and coverage pattern of associated communities of mosses-lichens along a pedoenvironmental gradient in Maritime Antarctica.

Maritime Antarctica is one of the major terrestrial ecosystems dominated by lichens and mosses, which represent important ecological indicators. Thus, we aimed to evaluate the changes in associated communities of mosses-lichens diversity and coverage along a pedoenvironmental gradient on Half Moon Island, Maritime Antarctica. We focused on how patterns in associated communities of mosses-lichens species diversity (richness, species composition and beta diversity) and coverage are associated with soil properties using plant inventory data from 174 plots across 14 contrasting pedoenvironments.
