Summary Ecological and evolutionary research increasingly uses quantitative synthesis of primary studies (meta‐analysis) for answering fundamental questions, informing environmental policy summarizing results decision makers. Knowing how meta‐analysis works is important researchers so that their can have broader impact. Meta‐analytic thinking encourages scientists to see single as substantial contributions a larger picture. To facilitate inclusion in meta‐analysis, relevant must be found...
Summary Plant diversity is globally threatened by anthropogenic land use including management and modification of the natural environment. At regional local scales, numerous studies world‐wide have examined its effects on plant diversity, but evidence for declining species mixed. This because, first, comes in many variations, hampering comparisons studies. Second, directly affects environment, indirect extend beyond boundaries use. Third, land‐use greatly depend environmental, historical...
Biodiversity conservation and agricultural production are often seen as mutually exclusive objectives. Strategies for reconciling them intensely debated. We argue that harmonization between biodiversity crop can be improved by increasing our understanding of the underlying relationships them. provide a general conceptual framework links through separate land use production. Hypothesized derived synthesizing existing empirical theoretical ecological knowledge. The suggests nonlinear caused...
Abstract Aim Biodiversity and ecosystem productivity vary across the globe, considerable effort has been made to describe their relationships. functioning research traditionally focused on how experimentally controlled species richness affects net primary ( S → NPP) at small spatial grains. In contrast, influence of (NPP ) explored many grains in naturally assembled communities. Mismatches scale between approaches have fuelled debate about strength direction biodiversity–productivity Here,...
Abstract Aim The species–area relationship ( SAR ) is a prominent concept for predicting species richness and biodiversity loss. A key step in defining s to accurately estimate the slope of relationship, but researchers typically apply only one global (canonical) slope. We hypothesized that this approach overly simplistic investigated how geographically varying determinants affect estimates vascular plants at scale. Location Global. Methods used data from 1032 geographical units size shape....
Abstract Meta‐analyses often encounter studies with incompletely reported variance measures (e.g., standard deviation values) or sample sizes, both needed to conduct weighted meta‐analyses. Here, we first present a systematic literature survey on the frequency and treatment of missing data in published ecological meta‐analyses showing that majority encountered studies. We then simulated meta‐analysis sets investigate performance 14 options treat impute SDs and/or SSs . Performance was...
Abstract Estimating biodiversity and its change in space time poses serious methodological challenges. First, there has been a long debate on how to quantify biodiversity, second, measurements of are scale‐dependent. Therefore, comparisons metrics between communities ideally carried out across scales. Simulations can be used study the behaviour scales, but most approaches system specific, plagued by large parameter spaces, therefore cumbersome use interpret. However, realistic spatial...
Forest products provide an important source of income and wellbeing for rural smallholder communities across the tropics. Although tropical forest frequently become over-exploited, only few studies explicitly address dynamics degradation in response to socio-economic drivers. Our study addresses this gap by analyzing factors driving changes perception communities. Using poverty environment network global dataset, we studied recently perceived trends product availability considering firewood,...
Species–area relationships (SARs) provide an avenue to model patterns of species richness and have recently been shown vary substantially across regions different climate, vegetation, land cover. Given that a large proportion the globe has converted agriculture, considering variety in agricultural management practices, key question is whether global SARs gradients intensity. We developed for mammals account geographic variation biomes, cover range land‐use intensity indicators representing...
Abstract Aim Land‐use change is considered a major threat to biodiversity. Species–area relationships ( SAR s), which are often used assess biodiversity changes, assume that land use leads the loss of natural habitats. Yet, in regions with long land‐use histories, such as Europe, many species have persisted in, or even depend on, landscapes heavily influenced by (i.e., countryside landscapes). Here, we develop model considers conservation value landscapes, and how affects plant‐species...
Plant species richness is essential for ecosystem functioning, resilience and services, yet globally threatened by anthropogenic land use, including management modification of the natural environment. At broad scales, land-use effects are often simply modelled habitat loss, assuming that transformed becomes completely inhospitable naturally occurring species. Further, estimates losses flawed common assumption a universal slope species–area curve, typically ranging from 0.15 to 0.35. My PhD...
Abstract 1. Estimating biodiversity and its changes in space time poses serious methodological challenges. First, there has been a long debate on how to quantify biodiversity, second, measurements of change are scale-dependent. Therefore comparisons metrics between communities ideally carried out across scales. Simulation can be used study the utility scales, but most approaches system specific plagued by large parameter spaces therefore cumbersome use interpret. However, realistic spatial...

We then simulated meta-analysis sets investigate performance 14 options treat impute SDs and/or SSs. Performance was thereby assessed...
