One hypothesis that can potentially explain the latitudinal richness gradient is the tropical conservatism hypothesis (TCH). The TCH proposes that there are presently more species in tropical regions because many clades originated in the tropics and have only colonised the temperate zones more recently, leaving less time for speciation to build up temperate richness, and with niche conservatism limiting temperate colonisation by tropical clades. Here, we review the empirical evidence for the TCH. We first define this hypothesis, outline its major predictions, and describe its relationship to similar hypotheses. We then perform a systematic review to quantitatively evaluate the support for (and against) its major predictions. Finally, we describe several areas for future research.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Global.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Time Period</h3>\u0000 \u0000 <p>Present to ~750 million years ago.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Major Taxa Studied</h3>\u0000 \u0000 <p>All (especially plants and animals).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We perform a systematic review of the evidence for the TCH over the last ~20 years.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Most predictions of the TCH were supported in a significant majority of the studies that examined them.

Vicariance events explain the origin of many of these species; however, dispersal events also played a significant role in the biogeographic history of the group. The areas of endemism of Pteridaceae in Brazil have distinct biogeographic histories. The areas of southeastern Brazil and southeastern Bahia likely originated more recently, driven by Pleistocene climatic changes and habitat specialisations. In contrast, southern Brazil and the Guiana Shield have older taxa, which originated in regions with climatic and (or) geological stability through habitat specialisations.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The origin of most species present in the Amazon Forest, Brazilian Atlantic Forest and Dry Diagonal most likely resulted from climatic changes during the Miocene and Pleistocene.

Resolving these evolutionary enigmas would establish a crucial foundation for understanding biogeographic evolution in this topographically complex region. Therefore, we integrated phylogenetic, demographic, and ecological niche analyses to elucidate the roles of ancient tectonism, Quaternary climatic fluctuations, and niche evolution in shaping its diversification and distribution.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>Southern China.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Using two mitochondrial and eight nuclear genes, we reconstructed phylogenetic relationships, estimated divergence times and assessed population dynamics. Ecological niche models (ENMs) were optimised via the ‘Kuenm’ package, and niche overlap, equivalency, and similarity were quantified using the ‘ecospat’ R package. Acestral niche and climatic tolerances reconstruction were used in the ‘phyloclim’ package.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The OSC comprises nine species and originated from a mid-Miocene ancestor (~12.55 Ma). Mitochondrial phylogeny resolved four deeply divergent clades, while nuclear gene phylogeny revealed incomplete lineage sorting (ILS) and historical gene flow (STRUCTURE, <i>K</i> = 7; JML, <i>p</i> &gt; 0.05). Post-last glacial maximum (LGM) expansions (~0.02 Ma) facilitated secondary contact in sympatric zones, where niche conservatism dominated between sister species. Ancestral niche reconstruction identified precipitation variables as key drivers of early divergence, while thermal tolerances evolved conservatively. The results indicated that Miocene uplift of the Qinghai-Tibet Plateau (~12.55–8.70 Ma) promoted southward expansion, while Pliocene-Pleistocene (~5.58–2.40 Ma) river reorganisations fragmented and later connected populations.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Conclusions</h3>\u0000 \u0000 <p>The OSC's diversification reflects the interplay between Miocene–Pliocene tectonism and Quaternary climatic cycles. While ancestral niche divergence along precipitation gradients initiated speciation, post-LGM sympatry favoured conservatism in thermal microhabitats. Combining multilocus phylogenetics, demographic inference, and niche modelling resolves the rapid-radiating models in the frog complex and highlights the dynamic roles of landscape features in shaping biogeographic patterns of them.</p>\u0000 </section>\u0000 </div>","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"52 8","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611943","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}
