Abstract As a megadiverse country with three global biodiversity hotspots, a growing human population, and a rapidly developing economy, South Africa exemplifies the challenges facing modern conservation biology. South Africa has established a protected areas network which encompasses 1527 National Parks, nature reserves, wilderness areas, mountain catchment areas, and World Heritage sites. However, the contribution of South Africa's protected areas to biodiversity conservation remains poorly kn...

As a megadiverse country with a rapidly growing population, South Africa is experiencing a biodiversity crisis: natural habitats are being degraded and species are becoming threatened with extinction. In an era of big biodiversity data and limited conservation resources, conservation biologists are challenged to use such data for cost-effective conservation planning. However, while extensive, key genomic and distributional databases remain incomplete and contain biases. Here, we compiled data on...

Abstract Human activity is accelerating rates of extinction around the world, and there is therefore an urgent need to understand the potential consequences of species loss on functional diversity ...

Parasites that infect multiple species cause major health burdens globally, but for many, the full suite of susceptible hosts is unknown. Proactive disease surveillance involves gathering host-parasite association data, predicting missing links, and targeting efforts towards the most likely undocumented interactions. Using the largest global network of mammal host-parasite interactions amalgamated to date (>29,000 interactions), we predict undocumented links and conduct targeted literature searc...

To date, our understanding of how species have shifted in response to recent climate warming has been based on a few studies with a limited number of species. Here we present a comprehensive, global overview of species9 distributional responses to changing climate across a broad variety of taxa (animals, plants, and fungi). We characterise species9 responses using a metric that describes the realised velocity of climate change: how closely species9 responses have tracked changing climate through...

: A sixth great mass extinction is ongoing due to the direct and indirect effects of human pressures. However, not all lineages are affected equally. From an anthropocentric perspective, it is often purported that humans hold a unique place on Earth. Here, we show that our current impacts on the natural world risk realizing that expectation. We simulated species loss on the mammalian phylogenetic tree, informed by species current extinction risks. We explored how Homo sapiens could become isolat...

Identifying patterns and drivers of infectious disease dynamics across multiple scales is a fundamental challenge for modern science. There is growing awareness that it is necessary to incorporate multi-host and/or multi-parasite interactions to understand and predict current and future disease threats better, and new tools are needed to help address this task. Eco-phylogenetics (phylogenetic community ecology) provides one avenue for exploring multi-host multi-parasite systems, yet the incorpor...

Climate change affects not just where species are found, but also when species’ key life-history events occur—their phenology. Measuring such changes in timing is often hampered by a reliance on biased survey data: surveys identify that an event has taken place (for example, the flower is in bloom), but not when that event happened (for example, the flower bloomed yesterday). Here, we show that this problem can be circumvented using statistical estimators, which can provide accurate and unbiased...

Languages are being lost at rates exceeding the global loss of biodiversity. With the extinction of a language we lose irreplaceable dimensions of culture and the insight it provides on human history and the evolution of linguistic diversity. When setting conservation goals, biologists give higher priority to species likely to go extinct. Recent methods now integrate information on species evolutionary relationships to prioritize the conservation of those with a few close relatives. Advances in ...

The merger of phylogenies with ecology has given rise to the field of “community phylogenetics” predicated on the assumption that ecological differences among species can be estimated from phylogenetic relationships (the phylogenetic distance/ecological difference, PDED, hypothesis). A number of studies have failed to find strong support for this assumption, thus challenging the utility of phylogenetic approaches. This gap might highlight the fact that the PDED relationship is not useful for com...
