During these fieldworks, a total of 1271 specimens were collected and deposited in the Herbarium of the University of Concepción (CONC). To compile the catalog, specimens collected in 10 additional locations by previous researchers were added to these botanical collections. The catalog comprises 261 species belonging to 70 families. Among these species, 203 are native, and 23 are introduced. The species in the catalog are classified into the divisions Pteridophyta (32), Pinophyta (3), and Magnoliophyta (226); within this last division, the classes Liliopsida (74) and Magnoliopsida (152) are represented. This first floristic catalog of PNBO is of great importance due to the park's vast territorial expanse and geographical location. It contributes to the fundamental understanding of the biodiversity of this challenging-to-access southern territory and the country as a whole.","PeriodicalId":475798,"journal":{"name":"Anales del Instituto de la Patagonia","volume":"44 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140668111","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}

{"title":"First catalogue of benthic marine macroalgae from glacier-influenced environments of the Beagle Channel, deposited in the new Sub-Antarctic Cryptogamic Herbarium (SCH) of the University of Magallanes","authors":"Juan Pablo Rodriguez Provoste, Violeta Gibelli, Francisco Bahamonde, J. Marambio, Marta Calderón, Danilo Bustamante, Ricardo Rozzi, Andrés Mansilla","doi":"10.22352/aip202452003","DOIUrl":"https://doi.org/10.22352/aip202452003","url":null,"abstract":"The environmental characteristics and geomorphological landscape in the sub-Antarctic Magellanic ecoregion underpin a biological diversity that evolved adapting to the microhabitats produced by these heterogeneous ecological conditions. The high level of endemism found in these biological communities is nowadays protected thanks to the creation of the Cape Horn Biosphere Reserve (CHBR), a natural laboratory at the southern end of the sub-Antarctic Magellanic ecoregion. Studies produced in this region offer a valuable knowledge of its biological, ecological and cultural facets in a state still scarcely impacted by anthropogenic activities. The retreat of glaciers present along the channels and fjords of the CHBR due to global climate change impacts the marine benthic and macroalgae communities hosted in these water bodies. European expeditions in the 18th and 19th centuries pioneered the works which provided our current knowledge about this subantarctic marine flora. Nevertheless, there is still a gap of taxonomic information of macroalgae diversity in the CHBR. To solve this gap, with support of the Cape Horn Internationional Center (CHIC), we created the Sub-Antarctic Cryptogamic Herbarium (SCH) hosted at the Antarctic and Sub-Antarctic Marine Ecosystems Laboratory (LEMAS), University of Magallanes. In 2020, the New York Botanical Garden indexed the SCH in its Index Herbariorum. This indexation granted by this world-renowned institution places the SCH's biological collection as the world's southernmost cryptogamic repository. As such, the SCH's botanical collection is currently the only gateway to the subantarctic ecosystem's biological legacy. The catalogue below provides information about the ecological and morphological characteristics of macroalgae deposited in the SCH, with particular focus on those species present in the CHBR. We identified 54 species. Among them 23 belong to the Rhodophyta division (43%), 19 species to the Chlorophyta division (35%), and 12 species to the Ochrophyta division (22%). In the context of rapid global change, involving increasingly threatened taxa due to human impact, baseline studies and records deposited at the SCH will provide an essential tool for assessing patterns of change and defining conservation practices to protect the rich biodiversity of these sub-Antarctic ecosystems.","PeriodicalId":475798,"journal":{"name":"Anales del Instituto de la Patagonia","volume":"39 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140667271","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}

In these forests, birds are the group of vertebrates with the largest number of species. However, essential aspects of the ecology and morphology of several species in this region are still understudied. These species include the White-throated treerunner (Pygarrhichas albogularis, King 1831), considered a “living fossil” as it is the only living species of the genus Pygarrhichas. In addition, this Furnariid is endemic to the temperate forests of South America. Using the 23-year database of the Long-Term Ornithological Research Program of Omora Park (54º56’S, 67º38’W), based on monthly captures and banding of forest birds, we describe the morphology, longevity, and presence of the White- throated treerunner in the CHBR. Between 2000 and 2022, 91 individuals were captured, including 29 recaptures. Based on these recaptures we determined that this species can live for at least five years. Morphometric measures showed a positive correlation between bill measures and tarsus length with both tail and wing lengths. The average weight varied for each season but not significantly. The greater presence on old-growth forests sites suggests a dependence of treerunners on large trees. This study expands the knowledge about the natural history of the White-throated treerunner, particularly about its populations inhabiting the world’s southernmost forests","PeriodicalId":475798,"journal":{"name":"Anales del Instituto de la Patagonia","volume":"90 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140670480","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}

It is the least known species of the Gallinago genus and inhabits throughout the range of the biome of South American temperate forests, between the Maule region (36°S) and Cape Horn (56°S). In this biogeographical range, its reproductive and migratory habits are still poorly known. In this study, we report observations conducted between the years 2002 and 2023 in the Cape Horn National Park, with an emphasis on the most recent fieldwork on Horn Island. On this island, between January and October 2023, we recorded the autoecology of a family group composed of two adults and one juvenile. One of these adults was captured, banded, and measured in February 2023 (55°57.896’S - 67°13.478’W). The family group of G. stricklandii on Horn Island resided there during the summer, fall, winter, and spring seasons. This behavior contrasts with the migratory habit of the Magellanic snipe G. magellanica (King 1828), a better-known sympatric species. In addition to the resident habits of this family group and other individuals of G. stricklandii, we report new information about the morphology, feeding, and reproductive habits in the southern end of its distribution. This information recorded at the southern extreme of the American continent will enable new studies about this species and open up comparative analyses with other species of the cosmopolitan Scolopacidae family, which includes the world’s northernmost breeding birds at the boreal extreme of the Americas","PeriodicalId":475798,"journal":{"name":"Anales del Instituto de la Patagonia","volume":"129 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140669112","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}
