It presents results from analyses of several environmental variables including pH, EC, Ca, Mg, Na, K, shade, and height. The figures display density plots of AICc values for different evolutionary models (White Noise, Brownian Motion, Brownie 2-rate, Ornstein-Uhlenbeck, OU2, Lambda, and Delta) applied to these variables. Different line types in the plots likely represent different datasets or phylogenetic contexts. The study investigates whether traits related to these environmental factors exhibit niche conservatism, meaning they tend to remain similar over evolutionary time. The table provides a clear description of each evolutionary model, its abbreviation, its core assumptions regarding trait evolution in relation to phylogeny, and its key parameters, including rate of evolution (beta), strength of selection (alpha), trait optimum (theta), and multipliers for branch lengths (lambda and delta). Equivalencies between models are also noted, such as Brownian motion being a special case of White Noise and Ornstein-Uhlenbeck when selection is absent. This research contributes to understanding the evolutionary patterns of plant species, particularly Sphagnum mosses, in relation to their ecological niches and environmental conditions.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/johnson-sphagnum-niche/183430/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/johnson-sphagnum-niche/183430.png","ImageObject",300,407,{"name":92,"@type":93},"Arica Lee","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-23","2026-09-02",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",11,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What is the primary focus of this document?","Question",{"text":113,"@type":114},"This document focuses on modeling phylogenetic niche conservatism using various evolutionary models and analyzing how environmental variables relate to trait evolution in Sphagnum mosses.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"What does phylogenetic niche conservatism mean in this context?",{"text":118,"@type":114},"Phylylogenetic niche conservatism refers to the tendency for species to retain their ancestral ecological niches over evolutionary time, meaning traits related to their environment remain similar.",{"name":120,"@type":111,"acceptedAnswer":121},"Which environmental variables were analyzed?",{"text":122,"@type":114},"The environmental variables analyzed include pH, electrical conductivity (EC), calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), shade, and height.","https://schema.org",{"og:url":83,"og:type":125,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":127,"canonical":83},"index,follow",{"doc_id":129,"site_id":62},183430,1788352668,{"code":4,"msg":5,"data":132},{"doc_id":129,"user_id":133,"nickname":92,"user_avatar":134,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":26,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":130,"read_time":144,"preview_page_count":4},8796096645457,"https://ap-avatar.wpscdn.com/avatar/800003749518d68ffe3?x-image-process=image/resize,m_fixed,w_180,h_180&k=1779345340919836971","| warnstorfii\u003Cbr>contortum | girgensohnii\u003Cbr>height shade\u003Cbr>angermanicum austinii\u003Cbr>wulfianum rubellum\u003Cbr>na\u003Cbr>fimbriatumsquarrosum\u003Cbr>fuscum\u003Cbr>flavicomanscapillifolium\u003Cbr>rfumlseislafnmiinuem\u003Cbr>angustifolium obtusuenhgttsaecufuiiteummopnulnlammemumumictum subfulvumk lindbergiainlnrumnimi\u003Cbr>majus platyphyllum\u003Cbr>riparium\u003Cbr>|\n| --- | --- |\n\n| Model | Abbreviation | Description | Parameters | Equivalent to |\n| --- | --- | --- | --- | --- |\n| White noise | WN | Trait values independent of phylogenetic distance | Covariance |  |\n| Brownian motion | BM | Trait variance increases with phylogenetic distance | β—Rate of evolution | WN if β = !
