Abstract

This open access book richly illustrates the first, and comprehensive, account of the country’s biomes and ecoregions, the driving forces that account for their diversity and vulnerability, and the ecological principles that provide an understanding of the patterns and processes that have shaped landscapes, ecoregions, and ecosystems. Angola encompasses the greatest diversity of terrestrial biomes and is the second richest in terms of ecoregions, of any African country. Yet its biodiversity and the structure and functioning of its ecosystems are largely undocumented. The author draws on personal field observations from over 50 years of involvement in ecological and conservation studies in Angola and across Southern Africa. The vast recent literature published by researchers in neighboring, better resourced countries provides depth to the accounts of ecological principles and processes relevant to Angola and thus contributing to the understanding and sustainable management of its natural resources.

Abstract

This open access book. provides a synthesis of six projects, across ten countries, each of which have been sustained for two or more decades, and which illustrate how success can be achieved regardless of systems of governance, of a nation’s wealth, or of culture. Detailed narratives are presented on the key personalities that have conceived, conducted and concluded long-term projects: personal stories of vision, failure, frustration and persistence ultimately leading to success. The case studies vary widely in their geography and goals. The single-handed commitment to re-discover the last surviving populations of Giant Sable in the miombo woodlands of central Angola, through the capture, translocation and establishment of robust breeding herds of this magnificent antelope, contrasts with the massively funded, three-decade programme with over one hundred participants that reversed the annual loss to predation by feral cats of 455 000 seabirds from a sub-Antarctic island. Similarly, the foresight of Zimbabwean and Namibian ecologists to place rural communities at the centre of conservation programmes by giving value to wildlife populations and benefits to local people, transformed a land degradation problem to a socio-ecological solution. Across ten countries, building capacity in botanical collection, documentation and herbarium management expanded into a global project to place the knowledge base of Africa’s flora onto an electronic data system accessible to researchers and conservation planners in even the most remote corners of the continent. None of these projects enjoyed immediate results. Each required leadership skills that combined vision, a generosity of spirit, fortuitous timing and the exploitation of unexpected opportunities.

Abstract

Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate intactness scores: the remaining proportion of an intact reference population of a species group in a particular land use, on a scale from 0 (no remaining individuals) to 1 (same abundance as the reference) and, in rare cases, to 2 (populations that thrive in human-modified landscapes). The resulting bii4africa dataset contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the regions major land uses (urban, cropland, rangeland, plantation, protected, etc.) and intensities (e.g., large-scale vs smallholder cropland). This dataset was co-produced as part of the Biodiversity Intactness Index for Africa Project. Additional uses include assessing ecosystem condition; rectifying geographic/taxonomic biases in global biodiversity indicators and maps; and informing the Red List of Ecosystems.

Abstract

We outline a model and algorithm to perform inference on the palaeoclimate and palaeoclimate volatility from pollen proxy data. We use a novel multivariate non-linear non-Gaussian state space model consisting of an observation equation linking climate to proxy data and an evolution equation driving climate change over time. The link from climate to proxy data is defined by a pre-calibrated forward model, as developed in Salter-Townshend and Haslett (2012) and Sweeney (2012). Climatic change is represented by a temporally-uncertain Normal-Inverse Gaussian Levy process, being able to capture large jumps in multivariate climate whilst remaining temporally consistent. The pre-calibrated nature of the forward model allows us to cut feedback between the observation and evolution equations and thus integrate out the state variable entirely whilst making minimal simplifying assumptions. A key part of this approach is the creation of mixtures of marginal data posteriors representing the information obtained about climate from each individual time point. Our approach allows for an extremely efficient MCMC algorithm, which we demonstrate with a pollen core from Sluggan Bog, County Antrim, Northern Ireland., Comment: 25 pages, 7 figures
