Large tree mortality census KNP (2006-2018)

Maria Thaker, Abi Tamim Vanak & Rob Slotow
Fire and elephant herbivory are major drivers of large tree mortality in savanna ecosystems. While the spatial variation of these agents is well-studied, less attention has been paid to how disturbance history influences mortality risk for trees over time. In a long-term cohort study, we examined how the sequence of fire- and elephant-induced damage influences mortality of trees, and determined whether risk of mortality is compounded with time. Data on over 2500 large trees were...

Pollinator community predicts trait-matching between oil-producing flowers and a guild of oil-collecting bees

Hilke Hollens-Kuhr, Timotheüs Van Der Niet, Ruth Cozien & Michael Kuhlmann
The impact of pollinator community diversity on trait-matching in plant-pollinator interactions is poorly studied, even though many mutualisms involve multiple interaction partners. We studied ten communities in which one to three species of oil-collecting Rediviva bee pollinate the long-spurred, oil-producing flowers of Diascia ‘floribunda’ to examine how pollinator diversity affects covariation of functional traits across sites and trait-matching within sites. Floral spur-length was significantly correlated with weighted grand mean foreleg length of the local bee...

Data from: Community-level responses of African carnivores to prescribed burning

Laura Gigliotti, Goncalo Curveira-Santos, Rob Slotow, Craig Sholto-Douglas, Lourens Swanepoel & David Jachowski
Fires are common in many ecosystems worldwide, and are frequently used as a management tool. Although the responses of herbivores to fire have been well-studied, the responses of carnivores to fire remain unclear. In particular, post-fire habitat changes, and the associated changes in prey availability, might affect the coexistence or competition of carnivore species within the larger carnivore community, but few studies have focused on how fires influence multiple carnivore species simultaneously. Using South African...

The role of plant-pollinator interactions in structuring nectar microbial communities

Clara De Vega, Sergio Álvarez-Pérez, Rafael G. Albaladejo, Sandy-Lynn Steenhuisen, Marc-André Lachance, Steve D. Johnson & Carlos M. Herrera
1. Floral nectar harbours a diverse microbiome of yeasts and bacteria that depend predominantly on animal visitors for their dispersal. Since pollinators visit specific sets of flowers and carry their own unique microbiota, we hypothesize that plant species visited by the same set of pollinators may support non-random nectar microbial communities linked together by the type of pollinator. 2. Here we explore the importance of plant-pollinator interactions in the assembly of nectar microbiome and study...

Discordance in a South African Memecylon clade (Melastomataceae): Evidence for reticulate evolution

Prabha Amarasinghe, Phuc Pham, Robert Douglas Stone & Nico Cellinese
Premise of research. Evergreen forests in eastern South Africa have high biodiversity but are limited in extent and have a highly fragmented distribution. Populations of forest plants are thus geographically isolated, and fine-scale evolutionary studies of these lineages might yield important insights into the history and assembly of the forests themselves. Despite their morphological diversity, a prior study showed that three South African Memecylon taxa in Melastomataceae (M. natalense, M. bachmannii, and M. australissimum) had...
