Increasingly, researchers have advocated using historical context to inform ecological niche models (ENMs). Two key sources of past distributions are fossils and historical records. Fossils are subject to sampling and taphonomy biases but offer insights into temporal dynamics over millennia. Historical records are filtered by human perceptions over a shorter temporal window, but compared to fossils, provide different contextual information from a potentially broader range of habitats. New Zealand (NZ) has a relatively short history of human occupation, with rich fossil and historical literature archives. Approximately 25% of the world's seabirds breed in NZ, nearly half of which are burrowing procellariiforms. Since human arrival in NZ, most procellariiforms have declined in abundance and breeding ranges, primarily due to introduced mammalian predators. We combined record sources to improve ENMs of burrowing procellariiform breeding colonies and reconstruct narratives of decline.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Aotearoa New Zealand.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We fitted ENMs using a maximum entropy algorithm and mixed-principal component analysis for four sets of occurrence records (fossil, historic, historic + fossil and post-1990) of burrowing procellariiform breeding colonies, where taxa were grouped by functional traits.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;For all procellariiform trait groups, the breeding niche space captured separately by the fossils and historical data had low overlap, reflecting different environmental conditions.

Understanding how invasive species change their niche during invasion is fundamental for predicting their potential invasion risk in novel areas and environments. We here study the fall armyworm, FAW (<i>Spodoptera frugiperda</i>), one of the world's most devastating invasive pests due to its severe impact on cereal crops, posing a serious threat to agriculture. We first investigated climatic niche changes and tested for niche conservatism between native and invasive FAW ranges. We then modelled the potential FAW distribution to assess its invasion risk on a global scale, focusing on Europe and its agricultural areas.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Global, with a focus on Europe.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We analysed niche overlap and niche dynamics to quantify climatic niche changes between native and invasive FAW ranges. To predict potential climatically suitable areas for FAW invasion, we used species distribution models (SDMs) calibrated on native, invasive and global (both native and invasive) occurrence datasets.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Our results did not support niche conservatism between native and invasive FAW ranges. We observed a climatic niche shift and expansion in the invasive range towards warmer and drier areas. The highest potential climatic suitability for FAW invasion was identified in parts of Africa, India, China, Australia and in large areas of southwestern, central and southeastern Europe.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Conclusions</h3>\u0000 \u0000 <p>Given the observed niche shift and its strong migratory capacity, FAW is likely to further expand its range and establish itself in southern Europe, with potential seasonal migrations to more temperate regions driven by increased temperatures associated with ongoing climate change. Our study confirms that FAW poses a significant threat to global and European biodiversity and agriculture, highlighting the urgent need for coordinated monitoring efforts and the implementation of adaptive management strategies, including sustainable ones, to protect agricultural systems worldwide.</p>\u0000 </section>\u0000 </div>","PeriodicalId":51018,"journal":{"name":"Diversity and Distributions","volume":"31 5","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ddi.70037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unstructured designs are vulnerable to preferential sampling, where residual covariance between locations selected for sampling and the response variable of interest may render predictions strongly biased.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Innovation</h3>\u0000 \u0000 <p>We extend previous work to address preferential sampling in spatial single-species distribution models to a multivariate context. Using spatially structured latent variables to approximate residual covariance between species occurrence probabilities and sampling inclusion probabilities, we present ways to account for sampling that may be preferential to varying degrees across multiple species, where (analogously) multiple datastreams might be preferential to varying degrees for a single species, or both. We use simulation to explore our proposed model and present an application that delineates the distributions of 13 bumble bee species across Wisconsin, USA and evaluates evidence for preferential sampling within 3 citizen science datastreams.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Conclusions</h3>\u0000 \u0000 <p>Simulation results suggest that our proposed model improves out-of-sample predictions of species occurrence or richness when the sampling design is preferential and residual covariance between sampling and species occurrence exhibits spatial structure compatible with model assumptions, reducing bias in predictions of species occurrence or richness. Empirically, volunteers appeared to sample preferentially with respect to bumble bee distributions, being more likely to sample in locations where the federally listed <i>Bombus affinis</i> was more likely to occur. Our approach enables practitioners a means to triage preferential sampling within increasingly popular multi-species or integrated distribution models and can be modified slightly to deal with a variety of other response variables.</p>\u0000 </section>\u0000 </div>","PeriodicalId":51018,"journal":{"name":"Diversity and Distributions","volume":"31 5","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ddi.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
