ABSTRACT Rivers are conduits for materials and energy; this, the frequent intense disturbances that these systems experience, their narrow, linear nature, create problems conservation of biodiversity ecosystem functioning in face increasing human influence. In most parts world, riparian zones highly modified. Changes caused by alien plants — or environmental changes facilitate shifts dominance creating novel ecosystems often important agents perturbation systems. Many restoration projects...
Many ecosystems have been transformed, or degraded by human use, and restoration offers an opportunity to recover services benefits, not mention intrinsic values. We assessed whether scientists practitioners use their projects demonstrate the benefits can provide in peer-reviewed publications. evaluated a sample of academic literature determine links are made explicit between ecological restoration, society, public policy related natural capital. analyzed 1,582 papers dealing with published...
Abstract Humanity is on a deeply unsustainable trajectory. We are exceeding planetary boundaries and unlikely to meet many international sustainable development goals global environmental targets. Until recently, there was no broadly accepted framework of interventions that could ignite the transformations needed achieve these desired targets goals. As component IPBES Global Assessment, we conducted an iterative expert deliberation process with extensive review scenarios pathways...
Abstract Aim To examine the different uses and perceptions of introduced Australian acacias (wattles; Acacia subgenus Phyllodineae ) by rural households communities. Location Eighteen landscape‐scale case studies around world, in Vietnam, India, Réunion, Madagascar, South Africa, Congo, Niger, Ethiopia, Israel, France, Portugal, Brazil, Chile, Dominican Republic Hawai‘i. Methods Qualitative comparison studies, based on questionnaire sent to network acacia researchers. Information individual...
Summary Quantification of ecosystem services ( ES ) is an important step in operationalizing the concept for management and decision‐making. With exponential increase research, have become a ‘catch‐all phrase’, which some suggest has led to poorly defined, impractical ambiguous concept. An overview methods used quantification needed examine their scientific rigour provide guidelines selecting appropriate measures. We present systematic review 405 peer‐reviewed research papers address...
Summary Climate change in South Africa may threaten the sclerophyllous evergreen shrubs of this region. Available data suggest that they are not as tolerant water stress chaparral occurring climatically similar California, USA. Seventeen species from nine angiosperm families, including both fynbos and succulent karoo species, were studied at a field site Western Cape Province, Africa. Minimum seasonal pressure potential ( P min ), xylem specific conductivity K s stem strength against...
Abstract Aim We explored morphological and ecophysiological traits that enable invasive Australian acacias to compete with native species for resources (light, water nutrients) necessary support the substantial growth associated successful invasions. Location Global. Results Invasive grow large seed prolifically in invaded regions. The greater capacity vegetative is underpinned by their ability acquire efficiently use non‐native habitats. Key biological enhance acquisition include (1) rapid...
Significance Forecasts of global change impacts on biodiversity often assume that the current geographical distributions species match their ecological niches. Here we examine this assumption using an extensive dataset large-scale variation in demographic rates enables us to quantify demography-based niches 26 plant species. Contrasting these with species’ geographic reveals niche–distribution mismatches can be large and depend key life-history traits: poorly dispersed are absent from...
Private land conservation areas (PLCAs) are increasingly looked to for meeting the deficit left by state-owned protected in reaching global targets. However, despite increasing extent and recognition of PLCAs as a complementary strategy, little research has been done quantify their effectiveness; critical consideration if they be counted towards international biodiversity The long history South Africa provides an interesting case study address this knowledge gap. Here, we quantified...
Abstract Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing recent advances expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process estimate ‘intactness scores’: remaining proportion an ‘intact’ reference species group particular use, scale from 0 (no individuals) 1 (same abundance as reference) and, rare cases, 2 (populations that...
