Abstract Aim Tropical old‐growth grasslands are increasingly acknowledged as biodiverse ecosystems, but they understudied in many aspects. Geoxyle species a key component of these their belowground storage organs and bud banks functionally diverse contribute to the grasslands’ resilience. However, drivers geoxyles’ evolution (belowground) diversity little understood. Thus, we combined analyses on aspects diversity, functionality, ancestry, ecology geoxyles provide first comprehensive...
Strontium isotope (87Sr/86Sr) analysis with reference to strontium landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, forensics. However, despite the vast potential of research involving 87Sr/86Sr particularly Africa, Sr isoscapes remain unavailable for largest parts continent. Here, we measure ratios 778 environmental samples from 24 African countries combine this data published model a bioavailable isoscape sub-Saharan Africa using random forest...
Summary The miombo region in Africa is covered by a mosaic of woodlands and geoxylic grasslands subject to disturbances such as fires, frost drought, low nutrient availability. dominance Fabaceae Detarioideae species ecosystems remarkable but little understood. We therefore compared plant functional traits (PFTs) common woody the Angolan plateau, grouped life form (trees, geoxyles), lineage (Fabaceae: Detarioideae, non‐Detarioideae) symbiont association (ectomycorrhiza, rhizobia). PFTs...
Abstract Questions Forest–grassland boundaries in the tropics are primarily interpreted as driven by fire and herbivory. So far, frost has received little attention driver of tropical vegetation boundaries. Here, we study mid‐altitudes south‐central Africa ask following questions: (a) is there a lower treeline between grasslands forests on Angolan Plateau; (b) if so, do topoclimatic differences play role it; (c) what our results imply for highlands globally? Location The Plateau (10°–16°S...
Fire plays an important role in the ecology of tropical grasslands globally. However, detailed studies comparing response plant functional groups to fire seasonality, and thus phenological timing, are scarce from humid Afrotropical grasslands. Such information, however, is crucial for understanding what keeps open enabling evidence-based management, conservation. We initiated experiment frost- fire-prone Angolan geoxyle 2017, investigating effect different timing fires on cover diversity...
Abstract Over-exploitation of wildlife especially bushmeat trade is the second most important threat to animal biodiversity. This also applies Northern Angola but data on and hunting techniques for this region are rare. Therefore, we study common techniques, frequently captured species, their economic value, discuss local resource use in relation Angolan law urgent global crises like loss biodiversity, food supply South African countries, risk zoonoses. We recorded 27 localities province...
Four new species are described from central and eastern Angola adjacent NW Zambia. All occur in Kalahari sand savannas rich endemic more widely distributed geoxylic suffrutices. Despite being known very few collections, the conservation status of one these is assessed as Least Concern, grasslands nutrient-poor, remote sparsely populated areas, not threatened with conversion to agriculture. The remaining three treated Data Deficient. In addition, combination provided for...
Angola is a country in south-central Africa, particularly rich biodiversity. Despite the efforts recently made to document its biodiversity, there need for standardized sampling methods and compare variety of ecosystems plants occurring country. With this database report we aim abundance diversity woody species woodlands Huíla province. The hosts results standardised plot-based vegetation survey, consisting 448 plots distributed throughout 14 municipalities Bicuar National Park. In total,...
Angola is a tropical country with many biogeographical units and, therefore, has high floristic diversity. Although an increasing number of studies been carried out in recent years, the still considered to be underinvestigated as species being collected were previously unknown there. Several scientific groups working different parts contributed this paper their data from biodiversity assessments. With we can add 67 newly recorded for Angola, including two new generic records and five alien...
