Article
Full-text available
Angola is a tropical country with many biogeographical units and, therefore, has a high floristic diversity. Although an increasing number of floristic studies has been carried out in Angola in recent years, the country is still considered to be underinvestigated as many species being collected were previously unknown there. Several scientific grou...
Article
Fire plays an important role in the ecology of tropical grasslands globally. However, detailed studies comparing the response of 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 the grasslands open and for enab...
Article
Aim Tropical old-growth grasslands are increasingly acknowledged as biodiverse ecosystems, but they are understudied in many aspects. Geoxyle species are a key component in many of these ecosystems, their belowground storage organs and bud banks are functionally diverse and contribute to the grasslands’ resilience. However, the drivers of the geoxy...
Article
Full-text available
Over-exploitation of wildlife especially bushmeat trade is the second most important threat to animal biodiversity. This also applies to Northern Angola but data on bushmeat and hunting techniques for this region are rare. Therefore, we study the most common hunting techniques, frequently captured species, and their economic value, and discuss the...
Article
Questions Forest-grassland boundaries in the tropics are primarily interpreted as driven by fire and herbivory. So far, frost has received little attention as driver of tropical vegetation boundaries. Here, we study mid-altitudes in south-central Africa and ask the following questions: a) Is there a lower treeline between grasslands and forests on...
Article

Angola is a country in south-central Africa, particularly rich in biodiversity. Despite the efforts recently made to document its biodiversity, there is a need for standardized sampling methods to document and compare the variety of ecosystems and plants occurring in the country. With this database report we aim to document the abundance and divers...
Article
The miombo region in Africa is covered by a mosaic of woodlands and geoxylic grasslands and subject to disturbances like fires, frost and drought, and low nutrient availability. The dominance of Fabaceae Detarioideae species in miombo ecosystems is remarkable but little understood. We therefore compared plant functional traits (PFTs) of common wood...
Article
The Zambezian Floristic Region (ZFR) in south-central Africa experienced major environmental changes in the past and is nowadays home to numerous woody taxa of wet-tropical provenance. Within many taxa, we observe adaptations to multiple habitats, but know little about their environmental drivers. In order to gain knowledge about adaptation and spe...
Chapter
A small-scale mosaic of miombo woodlands and open, seasonally inundated grasslands is a typical aspect of the Zambezian phytochorion that extends into the eastern and central parts of Angola. The grasslands are home to so-called ‘underground trees’ or geoxylic suffrutices, a life form with massive underground wooden structures. Some (but not all) o...
Article
Full-text available
The SASSCAL region is home to a very rich biodiversity, which provides signifi cant economic and intrinsic value to human society. Th is biodiversity, however, is subject to multiple stresses emerging from human land use and climate change, which leads to biodiversity loss at substantial scale. To assess the current state and changes in biodiversit...

The SASSCAL region is home to a very rich biodiversity, which provides significant economic and intrinsic value to human society. This biodiversity, however, is subject to multiple stresses emerging from human land use and climate change, which leads to biodiversity loss at substantial scale.

Article
Eastern Angola and western Zambia are dominated by the Zambezi catchment, where high precipitation and a dense river network cause annual fl ooding of extensive areas from January to May. Cameia National Park in Angola is such a seasonally fl ooded savanna. A SASSCAL Biodiversity Observatory was established in May 2016, as little is known about the a...
Presentation
Full-text available
The western part of today’s Miombo region was strongly affected by the climatic changes at the Pliocene-Pleistocene boundary. Precipitation seasonality increased strongly, leading to the emergence of pronounced wet and dry seasons. Evergreen closed canopy forests disintegrated into a mosaic of open lands and dry forests. In this changing environmen...

TFO researchers presented their respective results concerning the targets to raise the awareness of people of the values of biodiversity (A1), to reduce the rate of loss of all natural habitats (B5), to enhance the area under conservation (C11), to enhance the contribution of biodiversity to carbon storage (D15) and to enhance the level of particip...

An undulating mosaic of forests and grasslands characterizes the Zambezian region in southern Africa that gave space to the stunning evolution of woody species pairs from many tropical plant families. These pairs have in common being of similar morphology, except for one aspect: while one species is growing as a tree in forests, the sister taxon gr...

Each "Biodiversity Observatory" forms an exactly surveyed square kilometer representative for a ecological zone. All "Biodiversity Observatories" serve for long-term observation of the change of diversity and composition of organisms and essential environmental key variables (regarding e.g. soil, climate, land use). Information, gained at these observatories can be extrapolated to a larger space.

Long-time vegetation monitoring at ten installed testsites along an altitudinal and climatic gradient from the fringes of the Sahara to the crest of the Jebel M'Goun. All Testsites had grazing exclosure plots from 2001 to 2010, and three still exist today. Population dynamics, species abundance and composition and climatic influence are observed among open and fenced plots at each testsite and among testsites along the gradient.
