Cobertura do solo e acumulação de nutrientes pelo amendoim forrageiro [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2003
O objetivo deste trabalho foi determinar as taxas de cobertura do solo, produção de biomassa e acumulação total de N, P e K da parte aérea da leguminosa herbácea perene amendoim forrageiro (Arachis pintoi Krapov. & W.C. Greg.), em diferentes densidades e espaçamentos de plantio. O delineamento experimental adotado foi de blocos ao acaso, em arranjo

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.

DINÂMICA DA COBERTURA DO SOLO POR PLANTAS E NDVI DE CULTIVARES DE SOJA EM DIFERENTES ARRANJOS ESPACIAIS DE PLANTAS

open access: yesColloquium Agrariae, 2018
A densidade de semeadura e o espacamento entre as fileiras podem influenciar no crescimento e desenvolvimento das culturas. O objetivo do trabalho foi avaliar a dinâmica do crescimento de duas cultivares de soja com tipo de crescimento indeterminado, em ...

Temporal Changes in Land Use Highlight the Vulnerability of Highland Grasslands in Protected Areas in Southern Brazil

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Subtropical Highland Grasslands showed greater net conversion than Mixed Ombrophilous Forest across our study PAs. In one PA created to conserve Highland Grasslands, net grassland loss inside the PA exceeded loss in adjacent buffer zones during the study period.

Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Disentangling seed availability and establishment filters at alpine treelines through a decade‐long field manipulation

open access: yesJournal of Ecology, Volume 113, Issue 12, Page 3830-3844, December 2025.
Treeline advance under warming occurs only when multiple filters align—adequate seed supply, favourable microclimatic windows, moderated herbivory and shrub effects that remain facilitative rather than competitive. Abstract Climate warming is expected to increase upslope shifts of alpine treelines globally.

Identifying priority areas for conservation to promote connectivity and mitigate the impacts of anthropogenic disturbance

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

INFLUÊNCIA DA COBERTURA DO SOLO NAS PERDAS DE ÁGUA E DESAGREGAÇÃO DO SOLO EM ENTRESSULCOS

open access: yesRevista Caatinga, 2009
The process of water erosion soil involves the detachment of particles soil by raindrop impact, the transport and consequently your deposition, by overland flow of water on the soil. This drainage happens in the flow form to laminate shallow what characterizes the interrill erosion.

Evaluating protected areas’ coverage of threats to terrestrial biodiversity

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

Relação entre cobertura e temperatura do solo em região periurbana do cerrado

open access: yesRevista Agrogeoambiental, 2019
A cobertura do solo e sua temperatura superficial estão associadas; portanto, alterações provocam mudança microclimática devido emissão de radiação eletromagnética na faixa termal. Neste estudo objetivou-se analisar a relação da cobertura do solo com a Temperatura Superficial Aparente (TSA) em área periurbana do cerrado através de imagens de satélite ...
