Segregation from heterospecifics commonly occurs in space, but it is often unknown whether such segregation has underlying environmental causes. Indeed, species could segregate because of different fundamental environmental requirements (i.e., ‘niche divergence’), because competitive exclusion at sympatric sites can force species to either change the habitat use they would have at allopatric sites (i.e., ‘niche displacement’) or to avoid certain areas, independently of habitat (i.e., ‘spatial avoidance’). Testing these hypotheses requires the comparison between sympatric and allopatric sites.

However, less work has been done on invertebrates. Similarly, the study of the island rule has been studied mainly in vertebrates. A group of invertebrates that can facilitate the study of TIB and the island rule are orchid bees (Apidae: Euglossini), because they are easily collected and show powerful flight performances that allows them to travel long distances. We wondered if these bees would follow the predictions of island biogeography, given that their populations may not be isolated across islands. To test if there is an homogenitazion of orchid bee communities across islands, we evaluated orchid bees abundance and species composition across islands. Besides, we tested the island rule by examining body size variations in individuals collected across islands.&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;Coiba National Park (Panama).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Time Period&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;May and June 2023.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxa&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Orchid bees (Hymenoptera: Apidae: Euglossini).&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;By using traps with chemical attractants, we sampled male bees from five islands and the mainland in Coiba National Park in the Pacific side of Panama. We tested the TIB by evaluating whether richness decreased with distance from the mainland or whether increased with island area. To investigate the island rule, and whether there is variation in body size across islands, we used &lt;i&gt;Euglossa imperialis&lt;/i&gt; and &lt;i&gt;Euglossa mixta&lt;/i&gt; as models, the two most abundant species in the study area.&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 the overall orchid bee community, we found that our results fit one of the predictions of IBT, increases in orchid bee abundance with island area; however, species richness did not decrease with isolation and did not increase with island area as predicted by TIB. An interesting result was that as distance from the mainland increased few species became more dominant. Regarding the island rule, we found in the two &lt;i&gt;Euglossa&lt;/i&gt; species a marked pattern of reduction in body size as distance from the mainland increased, which seems to outweigh the effect of island size, since the largest island and one of the farthest showed some of the smallest ","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"52 2","pages":"433-442"},"PeriodicalIF":3.4,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The opposite may be expected for clades originating under temperate conditions, but this temperate niche conservatism hypothesis has not been tested for a broad temperature gradient including both tropical and arctic climates. Liverworts are thought to have originated in temperate climates, and may thus follow the pattern of temperate niche conservatism. Here, we test this hypothesis using regional liverwort floras across a nearly full temperature gradient from tropical through temperate to arctic climates in North America. In addition, we investigate whether temperature-related variables and climate extreme variables play a more important role in determining phylogenetic structure of liverwort assemblages, compared to precipitation-related variables and climate seasonality variables, respectively.&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;North America.&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;Liverworts (Marchantiophyta).&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;Phylogenetic diversity (measured as mean pairwise distance) and phylogenetic dispersion (measured as standardised effect size of mean pairwise distance) in liverworts in regional floras in North America were related to latitude and climatic variables.
