Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs
Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.

Global-scale forest/non-forest (FNF) maps are of crucial importance for applications like biomass estimation and deforestation monitoring. Global FNF maps based on optical remote sensing data have been produced by the wall-to-wall satellite image ...

Strong evidence for negligible methyl chloroform (CH3CCl3) emissions from biomass burning [PDF]
With the phase-out of industrial methyl chloroform (MCF) production, the atmospheric burden of this ozone-depleting gas has rapidly declined. Therefore any non-industrial sources are taking on greater significance in the MCF budget.

Above ground woody community attributes, biomass and carbon stocks along a rainfall gradient in the savannas of the central lowveld, South Africa [PDF]
Enumeration of carbon stocks at benchmark sites is a necessary activity in assessing the potential carbon sequestration and possible generation of credits through restoration of intensively impacted sites.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Impact of forest management regimes on ligneous regeneration in the Sudanian savanna of Burkina Faso [PDF]
Annual early fire, selective tree cutting and grazing exclusion are currently used to manage the State forests of the Sudanian savanna of Burkina Faso, West Africa. Such prescriptions, however, are not based on experimental evidence.

Studies using climatic gradients play a key role in our understanding of the importance of rainfall and temperature as factors regulating species diversity and distribution, and thus of likely responses to climate change. However, such studies currently consider above‐ground species only, ignoring the diverse hypogaeic (subterranean) invertebrate fauna.

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]
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.
