Plant communities provide floral resource-landscapes for pollinators. Yet, it is insufficiently understood how these landscapes shape pollinator-mediated interactions among multiple plant species. Here, we study how pollinators and the seed set of plants respond to the distribution of a floral resource (nectar sugar) in space and across plant species, inflorescences and flowering phenologies. In a global biodiversity hotspot, we quantified floral resource-landscapes on 27 sites of 4 ha comprising 127,993 shrubs of 19 species. Visitation rates of key bird pollinators strongly depended on the phenology of site-scale resource amounts. Seed set of focal plants increased with resources of conspecific neighbours and with site-scale resources, notably with heterospecific resources of lower quality (less sugar per inflorescence). Floral resources are thus a common currency determining how multiple plant species interact via pollinators. These interactions may alter conditions for species coexistence in plant communities and cause community-level Allee effects that promote extinction cascades.

Plant species are known to be distributed on river banks in a sequence of community zones from the water’s edge to the outer riparian area. The interplay between flow and landscape is thought to drive the existence of these zones, and specifically, between a lower zone that is inundated most years and an upper zone that is inundated less frequently. There remains no consensus on the number of zones present, what their links to flow might be or whether the same zones occur in different basins. This paper reports on the number and nature of vegetation zones along South African rivers in different geographical areas and their relationship to the flow regime. River bank sites in four climatic areas of South Africa were found to support four vegetation zones (in two groups) despite major differences in vegetation community types, climate and patterns of river flow. The Wet bank and Dry Bank zones were separated at an elevation that correlated well with the 1:2 year flood line. If vegetation zones along rivers can be linked in this generic way to the flow regime of a river, it will strengthen our ability to predict vegetation changes likely to occur with flow modifications.

Calls for society to ‘reconnect with nature’ are commonplace in the scientific literature and popular environmental discourse. However, the expression is often used haphazardly without the clarity of the process involved, the practical outcomes desired, and/or the relevance to conservation. This interdisciplinary review finds that the Western disconnect from nature is central to the convergent social-ecological crises and is primarily a problem in consciousness. Connectedness with nature (CWN) is therefore defined as a stable state of consciousness comprising symbiotic cognitive, affective, and experiential traits that reflect, through consistent attitudes and behaviors, a sustained awareness of the interrelatedness between one’s self and the rest of nature. CWN sits on a continuum comprising information about nature and experience in nature but is differentiated as a more holistic process for realizing transformative outcomes that serve oneself and their community. Various instruments are available to measure the CWN construct, although their cross-cultural transferability is unclear. Multiple benefits of CWN linked to physical and psychological well-being have been identified and CWN is distinct in that it supports happiness and more purposeful, fulfilling, and meaningful lives. CWN has been found as a reliable predictor and motivation for environmentally responsible behavior (ERB). CWN may benefit conservation discourse by providing: a more compelling language; hope and buffering frustration in the face of environmental crises; a more enduring motivation for ERB; and an accepted avenue for tackling ‘fuzzy’ concepts often avoided in conservation. Bolstered by interdisciplinary collaborations and action-oriented education, CWN presents itself as a radical but necessary prerequisite for realizing desired conservation and environmental behavior outcomes.

The gap between science and practice has been highlighted in a number of scientific disciplines, including the newly developing domain of ecosystem service science, posing a challenge for the sustainable management of ecosystem services for human wellbeing. While methods to explore science-practice gaps are developing, testing and revisions of these methods are still needed so as to identify opportunities for mainstreaming ecosystem service science into development policies and practice. We designed and tested an approach to explore the presence and nature of a research-management gap in order to identify ways to close the gap, using a South African case study. Our combining of traditional review processes with stakeholder interviews highlighted that ecosystem services are not explicitly referred to by the majority of ecosystem management-related documents, processes or individuals. Nevertheless, at the local level, our approach unearthed strategic opportunities for bridging the gap in the tourism, disaster management and conservation sectors. We also highlighted the current trend towards transdisciplinary learning networks seen in the region. While we found a gap between the research and management of ecosystem services, a rigorous study thereof, which transcends its mere identification, proved useful in identifying key opportunities and challenges for bridging the gap.
