The positive relationship between spatial environmental heterogeneity and species diversity is a widely accepted concept, generally associated with niche limitation. However, limitation cannot account for negative heterogeneity–diversity relationships (HDR) revealed in several case studies. Here we explore how HDR varies at different scales provide novel theories small-scale co-existence that explain both HDR. At large of (e.g. landscape level), communities co-exist, promoting regional pool...
Summary Species absent from a community but with the potential to establish (dark diversity) are an important, yet rarely considered component of habitat‐specific species pools. Quantifying this remains challenge as dark diversity cannot be observed directly and must estimated. Here, we empirically test whether ecological requirements or co‐occurrences provide accurate estimates diversity. We used two spatially nested independent datasets, one comprising 3033 samples coastal grassland...
The availability of global microbial diversity data, collected using standardized metabarcoding techniques, makes microorganisms promising models for investigating the role regional and local factors in driving biodiversity. Here we modelled symbiotic arbuscular mycorrhizal (AM) fungi currently available data on AM fungal molecular (small subunit (SSU) ribosomal RNA (rRNA) gene sequences) field samples. To differentiate between effects, estimated species pools (sets potentially suitable...
Abstract Anthropogenic environmental changes in climate, land use and disturbance regimes, as well mass propagule transport are having dramatic effects on many ecosystems. Both conservationists ecologists need ecologically relevant metrics to quantify the condition of plant animal communities. However, current fail address invasion species native different community types same region, even though these ‘native aliens’ can serve valuable indicators recent habitat condition. We propose a novel...
Marine eutrophication is a pervasive and growing threat to global sustainability. Macroalgal cultivation promising circular economy solution achieve nutrient reduction food security. However, the location of production hotspots not well known. In this paper potential macroalgae high commercial value was predicted across Baltic Sea region. addition, limitation within adjacent macroalgal farms investigated suggest optimal site-specific configuration farms. The Saccharina latissima largely...
Large‐scale biodiversity maps are essential to macroecology. However, between‐region comparisons can be more useful if patterns of observed species richness supplemented by variations in dark diversity – the absent portion pool. We aim quantify and map plant across Europe using a measure that accounts for both diversity. To do this we need delimit suitable pools, evaluate potential limitation large‐scale dataset. used Atlas Florae Europaeae (ca 20% European mapped within 50 × km grid cells)...
Despite considerable criticism in recent years, the use of local (SL) and regional species richness (SR) plots has a long tradition to test for community saturation. The traditional approach been compare linear polynomial regression models untransformed measures SL SR with statistically significant or model indicating unsaturated saturated communities, respectively. This target much controversy owing statistical issues, confounding effects arbitrary choice size area, difficulty attributing...
ABSTRACT Aim The diversity–productivity relationship is a controversial issue in ecology. Diversity sometimes seen to increase with productivity but unimodal has often been reported. Competitive exclusion was cited initially account for the decrease of diversity at high productivity. Subsequently, roles evolutionary history (species pool size) and dispersal rate have acknowledged. We explore how effects species pool, competition combine produce different relationships. Methods use series...
For decades, ecologists have been testing for species saturation by using regression analysis to determine the relationship between local and regional richness. The cumulative result of scores studies meta-analyses has led a general consensus that evidence is relatively uncommon. However, bias induced on arbitrary choice area threatened undermine this even proposal abandon method entirely. Nonetheless, use local-regional richness relationships continues. We performed meta-analysis almost 100...
Ecosystems are simultaneously regulated by bottom-up (resources) and top-down forces (predators). However, because predator-prey interactions operate on spatial scales beyond the reach of manipulative experimentation, actual roles predators remain poorly understood. In ecosystems where naturally absent, biological invasions provide a unique experiment to shed light large-scale long-term effects in recipient ecosystem. We combined data from benthic monitoring, environmental conditions, census...
Ecosystems that develop on mine spoil can serve as significant sinks for CO 2 . The aim of this study was to estimate the rate carbon accumulation and its distribution along forest ecosystem partitions in young Scots pine ( Pinus sylvestris L.) plantations Narva oil shale opencast, Estonia. tree layer measured 2004 13 stands afforested with 2-year-old seedlings during 1968 1994.

Abstract Current methods for assessing the environmental impacts of marine non-indigenous species (NIS) are limited by insufficient data, an over-reliance on expert judgement and too coarse a spatial resolution, which hampers accurate local management. However, advances in data-driven analyses offer significant potential developing more comprehensive frameworks NIS ecosystems. This study fills this major gap management proposing practical framework that integrates systematic reviews,...
The degree to which biotic communities are regionally enriched or locally saturated, and roles of key structuring processes, remain enduring ecological questions. Prior studies reef-building corals the Indo-west Pacific (IWP) found consistent evidence regional enrichment, a finding subsequently questioned on methodological grounds. Here we revisit this relation, associated relations between richness abundance (as 'Effective Number Species'), coral cover, used as proxy for disturbance...
The Baltic Sea is a unique and sensitive brackish-water ecosystem vulnerable to damage from shipping activities. Despite high levels of maritime safety in the area, there continued risk oil spills associated harmful environmental impacts. Achieving common situational awareness between spill response decision makers other actors, such as merchant vessel Vessel Traffic Service center operators, an important step minimizing detrimental effects. This paper presents Next-Generation Smart Response...
