Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

International Savanna Fire Management Initiative

open access: yesBiodiversidade Brasileira, 2019
Due to colonisation, traditional ways of fire management have been suppressed across landscapes and as a result vast areas of country are poorly managed and degraded. Conventional methods of firefighting have largely failed. Climate change will make the

Spatial carbon, nitrogen and phosphorus budget of a village territory in the West African savanna : I. Element pools and structure of a mixed-farming system [PDF]

open access: yes, 2004
La viabilité des systèmes agropastoraux de savane ouest-africaine dépend largement de la gestion des ressources organiques endogènes car celles-ci satisfont les besoins locaux en nourriture, en fourrage et en bois, et maintiennent la qualité du sol.

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

open access: yesOikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.

Effects of land use pattern on invasive plant diversity in Guinean savanna ecosystems of Togodo protected area, Togo [PDF]

open access: yes, 2018
Tropical natural ecosystems host a very diverse flora and fauna and are key ecosystems for global climate and biogeochemical regulation. Unfortunately, in West African landscapes, large areas of savanna and forest have been progressively replaced or ...
