To reconcile environmental issues with socioeconomic development, the mitigation hierarchy emerges as a pivotal strategy that sequentially addresses impacts through structured approach of avoidance, minimization, remediation, and offsetting. No net loss (NNL) is achieved when biodiversity gains from all four stages are larger than project's impacts. Here, we assessed changes linked to implementation S11D Eliezer Batista iron mining Complex in Carajás National Forest, Pará state, Brazil, expecting losses due activities forest restoration offsets. We evaluated stocks based on biotic value product habitat importance actual conditions. Habitat importance, unique for each class land cover recognized within study site, evaluation naturalness, rarity endangerment, substitutability. Actual conditions computed field-surveyed key ecological attributes vegetation structure, community composition diversity, processes, able restitute, 4–6 years only, approximately 73 % old-growth The ranges 0 mine lands 1 patchy savanna formations stocking above ironstone outcrops (locally known cangas) amounts 0.43 units/ha secondary forests. Between 2008 2021, detected comprehensive land-use area: Cangas, farmlands forests decreased, while minelands increased considerably. Despite degradation, emergence contributed positive balance areas managed by company (+379 units), dominated outside company's boundaries (−171 units). Although like-for-like compensation canga remains challenging, thus conclude efforts initiated effectively reversed trajectory degradation prevailing landscape provided considerable region.

What is the Relationship Between Plant Trait Diversity and Geodiversity? A Plot‐Based, Pan‐European Analysis

Global Ecology and Biogeography, Год журнала: 2024, Номер 33(11)

Опубликована: Авг. 21, 2024

ABSTRACT Aim Heterogeneity of the Earth's abiotic surface and subsurface (geodiversity) is increasingly recognised as an important driver biodiversity. Theoretically, species' traits should match to conditions in local environment. Here, we test this for first time at a continental extent by analysing relationships between geodiversity plant trait diversity forested vegetation plots across Europe, three plot sizes (100, 400 1000 m 2 ). Location Europe. Time Period 1930–present. Major Taxa Studied Plants. Methods We analysed geodiversity–trait Europe 1 km resolution using 2637 from sPlotOpen database. computed (topographic, landform, wetness soil physical chemical heterogeneity) variables, combined with climate land use data analyse direct indirect effects on diversity, structural equation modelling. Results Topographic heterogeneity, annual temperature lesser degree, showed significant positive weak moderately strong association richness evenness all sizes. also detected multiple highly but components dimensions. Some notable exceptions include moderate negative silt heterogeneity divergence TWI sand evenness, respectively. Explained variance was low models, higher models plots. Evidence extremely weak. Main Conclusions Our findings suggest variable‐specific dominated topographic heterogeneity. Importantly, precision limited, are thus trying detect signal amongst high noise. Hence, signals may indicate more underlying patterns than our effect suggest.

Abstract Seed persistence, desiccation tolerance, and dormancy play a crucial role in plant population community dynamics. However, these life-history traits remain largely understudied perennial herbaceous species, particularly tropical ecosystems. We evaluated the seed storage behaviour, potential longevity, soil bank, alleviation field effects of after-ripening temperature time on Carajasia cangae – an endangered forb endemic to ironstone outcrops Eastern Amazon. performed germination experiments examine effect conditions (−20, 5 28°C, as well storage) viability, mean percentage. Our results suggested that C. seeds form transient bank show orthodox behaviour. The seeds' longevity was favoured all controlled relation soil-stored (field). marked loss viability less than 1 year, regardless condition, indicates low for long-term germplasm conservation through banking. fully alleviated after 3 months during dry season.

Specific island biogeographic and landscape features shape plant diversity and habitat specialism on edaphic quartz islands in an arid ocean

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 22, 2025

Abstract Edaphic habitat islands offer unique environmental conditions for plants and often harbour specialized floras, thus having high nature conservation value. Besides edaphic uniqueness, distinct spatial features landscape filters characterize islands. However, their role as drivers of biodiversity on remains unclear. We aim to quantify the extent which parameters (island shape characteristics, diversity) (insularity parameters, surrounding matrix effects) explain plant diversity natural in an arid hotspot. The quartz our study area (Knersvlakte, South Africa), resemble within a semi-arid vegetation matrix, hosting unique, predominantly dwarf locally endemic succulent plants. In comprehensive field survey, we sampled richness 47 analysed characteristics derived from satellite imagery. Island were most reliable predictors diversity. Including measures features, (e.g. contrast) improved predictive power several models. distance-based isolation had little explanatory value relation observed variance. These results suggest that can be effectively described using specific island biogeographic such or measuring systems may require alternative quantification methods incorporating properties. Based this study, recommend combining different biogeography terrestrial

ABSTRACT Spatial connectivity varies temporally due to fragmentation caused by drying and may potentially define the diversity composition of communities. We studied spatiotemporal patterns in three river networks (DRNs) Croatia, Czechia Hungary, with varying patterns, focusing on roles local environmental variables regional influences. aimed assess how variation (STcon) influenced metacommunity structure dynamics, contributing our understanding rapidly changing aquatic ecosystems under climate change. used a unique hydrological dataset novel approach quantify across DRNs spanning different time windows (30, 200, 365, 730, 1825 3650 days before sampling). These values summarised much each site had been exposed at scales. Then, we estimated correlation between these STcon (i.e., variables) spatial arrangement) metrics using hierarchical variance partitioning. Local were consistently strongly associated influences playing secondary but important role. Both regional‐scale showed similar all DRNs. also significantly assembly, but, contrast, differences altered relative importance STcons calculated for The DRN consistent seasonal drying, was markedly long‐term (730, 3650‐day windows). Hungary experienced more recent irregular exhibited associations short‐term (200‐day window), whereas positioned between, showing less clear association connectivity. This study concluded that although most caddisfly metacommunities, role connectivity, particularly context trends, marked. evident from catchment scale longer history permanence where have stronger impact. Thus, change‐induced might be reshaping impacts depending historical research demonstrates need consider both temporal processes better understand current trends. incorporation trends will improve ways which global change pressures reshape communities functioning essential ecosystems.

Scale dependence of landscape heterogeneity effects on plant invasions

Journal of Applied Ecology, Год журнала: 2022, Номер 59(5), С. 1313 - 1323

Опубликована: Фев. 24, 2022

Abstract Invasive alien species are among the most concerning threats to native biodiversity world‐wide, and level of landscape heterogeneity is considered affect spatial patterns their occurrence spread. However, as previous studies on these associations report contrasting results, role its susceptibility invasions remains poorly understood. Landscape usually described by two measures: configuration composition. Both measures may differently invasive impacts be additionally scale dependent. Nevertheless, relative contribution invasion known. We investigated effect components: (edge density) composition (number evenness land cover types) measured at different scales (from within 0.25 5 km studied locations) local abundance one plant in Europe, North American goldenrods ( Solidago canadensis S. gigantea ). Using publicly available geospatial environmental data a novel method based remote analysis Google Street View images, we collected analysed large dataset goldenrod along 1,347 roadside transects agricultural landscapes Poland. compositional configurational were positively associated with goldenrods, however, size relationships was dependent scale. While abundance–heterogeneity pronounced largest for heterogeneity, pattern opposite heterogeneity. Synthesis applications . clear correlate potential, occurrences plants generally higher more heterogeneous landscapes. dependence this association means that researchers practitioners miss if only concentrating single increasing rural widely introduced way promote farmland biodiversity, show it also support plants, thus conflict original goals biodiversity‐oriented strategies. Therefore, suggest implementing regular management eradication schemes Finally, demonstrate how using existing imagery can advance our understanding biology.
