We then generate a bipartite network (geographical cells—species) on which we apply the Map Equation clustering algorithm to delineate bioregions and identify their underlying copepod communities.

In this study, we address the importance of discontinuity among mountain systems for intraspecific genetic structure by investigating whether the geographical disjunction between the Alps and the Carpathians (and the related habitat gap) is the primary factor that shapes the genetic structure of the high-mountain plant populations. We compare the large-scale genetic structure of alpine plants from these two parts of the European Alpine System concerning the location of the main genetic split in the studied species, large-scale patterns of phylogeographical lineages and potential factors influencing their distribution.&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;The Alps and the Carpathians.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxon&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;22 alpine/subalpine vascular plant species.&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 performed Bayesian population structure analysis on genome-wide genotyping (AFLP) data and reconstructed relationships between individuals and populations using the PCoA and Neighbour Joining.

The major sources of persistent uncertainty of GCM simulations in the tropical Pacific are the double Inter-Tropical Convergence Zone bias, the cold tongue bias, and westward-extended El Niño-Southern Oscillation sea surface temperature anomalies. These biases complicate the prediction of winter precipitation and future drought prevalence in Hawaii.

The articles used mainly birds as study models (53.6%), followed by mammals (27.8%), anurans (10.5%), insects (7.2%), fishes (0.7%) and reptiles (0.3%). Most articles studied the existence of geographic variation among populations by comparing differences in signal features, such as frequency, duration or a combination of several signal features through ordination methods. The proportion of case studies (i.e., comparisons of different acoustic traits, with some studies including more than one comparison) finding geographic variation in acoustic signals was quite similar among all taxonomic groups (range 75.2%–82.7%) but differed between males and females (80.7% vs. 60.0%, respectively). We also identified a higher proportion of case studies finding acoustic differences among geographic regions when using as response variable multiple signal features (i.e., through ordination axes), followed by the use of acoustic signal type (i.e., categorical classification) or frequency. Besides, 69.7% of the case studies that assessed the relationship between acoustic similarity and geographic distance found a negative and significant pattern among these variables, while this was true only for 60.0% and 66.7% of the case studies assessing the relationship between acoustic similarity with genetic distance and ecological variables, respectively. Finally, when focussing on birds, there was a higher probability of finding geographic differences when using songs (84.2%) as the target vocalisation than when using calls (78.3%) and when considering as target species acoustic learners (83.4%) than when focussing on nonlearners (78.0%).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 ","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"52 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.15116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938737","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}

During the Quaternary, many Andean trees responded to climate change through upslope migrations but, while there is evidence of such ongoing migrations in many species, they are at rates far below what is needed to remain in equilibrium with the current climate. Similarly, given the number of generations required for adaptation and the long lifespans of many tropical trees, it is unlikely that most species will be able to adapt fast enough. This synthesis explores the role of migration-induced secondary contact and hybridisation as potential mechanisms for accelerating the adaptive response of Andean forests. Hybridisation, historically underappreciated in tropical trees, is increasingly recognised as an important driver of speciation and ecological diversity. It may facilitate gene flow and introgression, providing novel genetic combinations that enhance species resilience to climate change. This process can generate new allelic diversity, allowing species to adapt more rapidly than through mutation or selection on standing variation alone. However, hybridisation can also lead to negative outcomes like genetic swamping and outbreeding depression. Conservation strategies should consider the potential benefits and risks of hybridisation in maintaining biodiversity under changing environmental conditions. As habitat fragmentation and deforestation exacerbate the challenges faced by these forests, preserving habitat connectivity will be crucial to facilitate migration and gene flow, potentially aiding the survival of many Andean tree species in the Anthropocene.</p>","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"52 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.15113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938736","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}
