A standard protocol for reporting species distribution models

Ecography, Journal Year: 2020, Volume and Issue: 43(9), P. 1261 - 1277

Published: June 1, 2020

Species distribution models (SDMs) constitute the most common class of across ecology, evolution and conservation. The advent ready‐to‐use software packages increasing availability digital geoinformation have considerably assisted application SDMs in past decade, greatly enabling their broader use for informing conservation management, quantifying impacts from global change. However, must be fit purpose, with all important aspects development applications properly considered. Despite widespread SDMs, standardisation documentation modelling protocols remain limited, which makes it hard to assess whether steps are appropriate end use. To address these issues, we propose a standard protocol reporting an emphasis on describing how study's objective is achieved through series modeling decisions. We call this ODMAP (Overview, Data, Model, Assessment Prediction) protocol, as its components reflect main involved building other empirically‐based biodiversity models. serves two purposes. First, provides checklist authors, detailing key model analyses, thus represents quick guide generic workflow modern SDMs. Second, introduces structured format documenting communicating models, ensuring transparency reproducibility, facilitating peer review expert evaluation quality, well meta‐analyses. detail elements ODMAP, explain can used different objectives applications, complements efforts store associated metadata define standards. illustrate utility by revisiting nine previously published case studies, provide interactive web‐based facilitate plan advance encouraging further refinement adoption scientific community.

The geography of biodiversity change in marine and terrestrial assemblages

Science, Journal Year: 2019, Volume and Issue: 366(6463), P. 339 - 345

Published: Oct. 17, 2019

Spatial structure of species change Biodiversity is undergoing rapid driven by climate and other human influences. Blowes et al. analyze the global patterns in temporal biodiversity using a large quantity time-series data from different regions (see Perspective Eriksson Hillebrand). Their findings reveal clear spatial richness composition change, where marine taxa exhibit highest rates change. The tropics, particular, emerge as hotspots losses. Given that activities are affecting magnitudes directions differ across planet, these will provide much needed biogeographic understanding can help inform conservation prioritization.

Amazonia is the primary source of Neotropical biodiversity

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(23), P. 6034 - 6039

Published: May 14, 2018

Significance Amazonia is not only the world’s most diverse rainforest but also region in tropical America that has contributed to its total biodiversity. We show this by estimating and comparing evolutionary history of a large number animal plant species. find there been extensive interchange lineages among different regions biomes, over course tens millions years. stands out as primary source diversity, which can be mainly explained amount time Amazonian have occupied region. The exceedingly rich heterogeneous diversity American tropics could achieved high rates dispersal events across continent.

Extinction risk and threats to plants and fungi

Societal Impact Statement There is increasing awareness that plants and fungi, as natural solutions, can play an important role in tackling ongoing global environmental challenges. We illustrate how understanding current projected threats to fungi necessary manage mitigate risks, while building of gaps bias assessment coverage essential adequately prioritize conservation efforts. highlight the state art science point methods future studies needed species extinction. Summary Plant fungal biodiversity underpin life on earth merit careful stewardship increasingly uncertain environment. However, biases documented extinction risks plant impede effective management. Formal risk assessments help avoid extinctions, through engagement, financial, or legal mechanisms, but most lack assessments. Available cover c. 30% (ThreatSearch). Red List overrepresents woody perennials useful plants, underrepresents single‐country endemics. Fungal overrepresent well‐known are too few infer status trends. Proportions assessed vascular considered threatened vary between datasets: 37% (ThreatSearch), 44% (International Union for Conservation Nature Threatened Species). Our predictions, correcting several quantifiable biases, suggest 39% all with other remain unquantified, may affect our estimate. Preliminary trend data show moving toward Quantitative estimates based understate likely loss: they do not fully capture impacts climate change, slow‐acting threats, clustering risk, which could amplify loss evolutionary potential.

Sampling biases shape our view of the natural world

Ecography, Journal Year: 2021, Volume and Issue: 44(9), P. 1259 - 1269

Published: June 21, 2021

Spatial patterns of biodiversity are inextricably linked to their collection methods, yet no synthesis bias or consequences exists. As such, views organismal distribution and the ecosystems they make up may be incorrect, undermining countless ecological evolutionary studies. Using 742 million records 374 900 species, we explore global impacts biases related taxonomy, accessibility, ecotype data type across terrestrial marine systems. Pervasive sampling observation exist animals, with only 6.74% globe sampled, disproportionately poor tropical sampling. High elevations deep seas particularly unknown. Over 50% in most groups account for under 2% species citizen‐science exacerbates biases. Additional will needed overcome many these biases, but must increasingly value publication bridge this gap better represent species' distributions from more distant inaccessible areas, provide necessary basis conservation management.

Widespread sampling biases in herbaria revealed from large‐scale digitization

Summary Nonrandom collecting practices may bias conclusions drawn from analyses of herbarium records. Recent efforts to fully digitize and mobilize regional floras online offer a timely opportunity assess commonalities differences in sampling biases. We determined spatial, temporal, trait, phylogenetic, collector biases c . 5 million records, representing three the most complete digitized world: Australia ( AU ), South Africa SA New England, USA NE ). identified numerous shared unique among these regions. Shared included specimens collected close roads herbaria; more frequently during biological spring summer; threatened species less frequently; relatives similar numbers.

Blind spots in global soil biodiversity and ecosystem function research

Soils harbor a substantial fraction of the world's biodiversity, contributing to many crucial ecosystem functions. It is thus essential identify general macroecological patterns related distribution and functioning soil organisms support their conservation consideration by governance. These analyses need represent diversity environmental conditions that can be found worldwide. Here we characterize existing gaps in taxa data across studies 17,186 sampling sites globe. include important spatial, environmental, taxonomic, functional gaps, an almost complete absence temporally explicit data. We also limitations explore biodiversity-ecosystem relationships, with only 0.3% all having both information about biodiversity function, although different taxonomic groups functions at each site. Based on this information, provide clear priorities expand research. Soil organism contributes but function have not been equivalently studied authors locations, environment types, for which there currently lack literature.
