Dung mosses (Splachnaceae), have evolved to utilise insects to disperse spores to habitat sites consisting of dung or dead animals—a marked departure from the wind based spore dispersal seen in other mosses. However, adapting to insect dispersal likely precludes long distance airborne dispersal, and limits dispersal events to the movements of the spore bearing insect. However, there are several disjunct populations of these mosses, incompatible with insect dispersal, raising questions over the manner of their origin. Hypotheses put forward include the dispersal of the mosses to these sites by birds. Here, the possibility that insectivorous birds could internally transport spores is explored by feeding insects bearing spores to captive myna birds. We tested if the spores of the New Zealand dung moss, Tayloria callophylla, can survive gut passage. Ultimately 9 of 10 dung samples produced viable moss colonies after a period of 30 days, demonstrating the survival of the spores through an avian digestive tract. Our results provide evidence for a unique model of dispersal in dung mosses, where a spore bearing insect is eaten by a bird that eats insects transports the spores in its gut over a much greater distance than otherwise likely with the insect alone.","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":" 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was done in the mangroves of Bocas del Toro Province, Panama, in September 2016 and, July, May and August 2017. Bryophytes were collected from prop or stilt roots of mangroves, the mid-lower part of the trunks and the lower branches. In areas inundated at high tide, additional samples were collected on the cortex of palms, its rootlets, other angiosperm trees and from decomposing logs. Twenty-six species of liverworts and seven of mosses were identified. The most diverse and predominant liverwort family was the Lejeuneaceae with twenty-two species and two varieties and, among the mosses, the Calymperaceae with three species. Species affinities with other tropical mangroves were analyzed and liverworts were found to be the dominant element. Among the liverworts collected, two are new reports for Panama: Ceratolejeunea confusa and Frullanoides mexicana. Additional surveys of the cryptogamic vegetation of Panamanian mangroves are urgently needed due to the accelerated deforestation caused by anthropic activities and the potential loss of important biodiversity.","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42364424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The processes behind these disjunct distributions remain a source of debate due to differences in species vagility, biogeographical history, and complex geological and climatic changes. We address the phylogenetic relationships and biogeographical history of the austral hornwort genus Phaeomegaceros based on eight molecular markers from the three genomes (nuclear: phytochrome, mitochondrial: nad5, and chloroplast: rbcL, trnL intron, trnL-trnF spacer, rps4 gene, rps4-trnS spacer, and matK gene). With ten taxa based on morphological and molecular data, the three phylogenetic analyses supported the genus Phaeomegaceros as monophyletic. Phaeomegaceros is composed of two major clades corresponding to the New Zealand species, which presents a conspicuous trilete mark with one depression in the middle of the spore’s proximal face, and the Austral American species, which lack this middle depression. Dating and biogeographical analyses indicate that the Phaeomegaceros ancestral area was New Zealand and Antarctica in the Late Cretaceous (53.51 Ma, HPD 95% = 31.64–72.63). While Austral American species diverged during the Eocene. We speculate that climatic fluctuations in the Antarctic continent during the middle to late-Miocene led to the isolation of Phaeomegaceros taxa with both processes (dispersal events and vicariance) acting on the independent evolution of the disjunct clades. Furthermore, recent diversification of Phaeomegaceros taxa in Austral America and range expansion to northern Andes and oceanic islands, are explained by dispersal events and subsequent cladogenesis coinciding with the uplift of the Andes and the formation of volcanic oceanic islands (Juan Fernandez and Tristan da Cunha).","PeriodicalId":93270,"journal":{"name":"Bryophyte diversity and evolution","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44935833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
