Two new species of Calea ser. Multiplinerviae (Asteraceae: Neurolaeneae) from Brazil

Nordic Journal of Botany, EarlyView.
Detailed studies of specimens from Rondônia and Mato Grosso do Sul showed that two new species have been misidentified: Calea micropappa resembles Calea pilosa, but differs by leaf apex obtuse to acuminate (versus acute), paleae present (versus paleae absent), disc corolla lobes 1.2–1.3 mm long (versus 0.7–0.8 mm), and pappus scales 0.1–0.25 mm long ...

The Paleoenvironment of the Ndutu Bed at Olduvai Gorge in the Context of Middle Stone Age Expansion in Eastern Africa: A Multiproxy Approach to Ungulate Analyses From the Victoria Cabrera Site and Dorothy Garrod Site (MIS 5)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The study of the Eastern African archaeological record is essential for understanding the origin and evolution of the Middle Stone Age (MSA). However, Olduvai Gorge, one of the primary regions in human evolution studies, has few sites associated with the MSA.

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

Oikos, 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.

Determinants of adoption and intensity of use of balanced nutrient management systems technologies in the northern Guinea savanna of Nigeria [PDF]

As part of a major effort to address soil fertility decline in West Africa, a project on Balanced Nutrient Management Systems (BNMS) has since 2000 been implemented in the northern Guinea savanna (NGS) of Nigeria.

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

Oikos, EarlyView.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

People and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.
