  • Efectos de atropellos vehiculares sobre la fauna de aves y mamíferos
           en Magallanes, en verano

    • Abstract: RESUMEN: Para aves y megamamíferos, se describe tanto la abundancia como los registros de fauna atropellada en verano, en carreteras pavimentadas y caminos ripiados de la Región de Magallanes, Chile. En ambos tipos de rutas, dos especialistas realizaron recorridos vehiculares, registrando en cada kilómetro, el número de aves y mamíferos, vivos y atropellados. El carancho fue la especie de rapaz más abundante en las carreteras asfaltadas en relación a los caminos ripiados, mientras que el guanaco fue el mamífero más abundante, tanto en carreteras como caminos. Se registraron siete especies atropelladas recientemente, cuatro mamíferos y tres aves, todas en carreteras asfaltadas, no registrándose atropellos en caminos de ripio. La liebre fue el mamífero con mayor cantidad de atropellos. Se discuten los efectos negativos y positivos de los caminos sobre los grupos de fauna estudiados.ABSTRACT: For birds and megamammals, both the abundance and records of fauna roadkill in summer, on paved roads and gravel roads in the Magallanes Region, Chile, are described. In both types of routes, two specialists conducted vehicle routes, recording the number of birds and mammals, both alive and hit by vehicles, for each kilometer. The southern caracara was the most abundant species of raptor on paved roads in relation to gravel roads, while the guanaco was the most abundant mammal, both on roads and paths. Seven species were recently hit by roadkill, four mammals and three birds, all on the paved road, with no roadkill recorded on gravel roads. The hare was the mammal with the highest number of run-overs. The negative and positive effects of the roads on the fauna groups studied will be analyzed.
       
  • Roedores nativos de la Reserva de Biosfera Cabo de Hornos en el extremo
           sur de Chile: avances en su conocimiento y conservación

    • Abstract: RESUMEN: Rodentia Bowdich, 1821, constituye el orden más diverso de mamíferos a nivel mundial. De éstos, la subfamilia Sigmodontinae Wagner, 1843 reúne ca. 490 especies, distribuidas mayormente en el Neotrópico. En Chile, el número de especies de sigmodontinos supera ampliamente la diversidad de otros grupos de roedores, pero el número de especies disminuye marcadamente hacia latitudes mayores. La Reserva de Biósfera Cabo de Hornos (RBCH), ubicada en el extremo austral del continente americano, alberga especies de abrotriquinos, euneominos y orizominos y algunas formas nominales pertenecientes a estas tribus, cuya distinción específica no ha sido explorada desde su descripción. Los pocos antecedentes sobre los roedores de la RBCH incluyen información anecdótica de exploradores y naturalistas del siglo XIX e inicios del XX. El presente estudio es un primer acercamiento a la caracterización del ensamble actual de roedores nativos de la RBCH y la variación genética de la especie con mayor abundancia y amplia distribución en los archipiélagos del extremo sur de Chile. Entre el 2002 y el 2023 se han realizado 10 expediciones a los Parques Nacionales Alberto de Agostini, Cabo de Hornos y Yendegaia. Durante las expediciones realizadas en el 2023, se colectaron 106 individuos de Abrothrixlanosa (Thomas, 1897) (n=1), A. olivacea (Waterhouse, 1837) (n= 93) y Oligoryzomys longicaudatus (Bennett, 1832) (n=12). El ratón oliváceo (A. olivacea) no solo fue la especie más abundante, sino que también la única capturada en la porción más austral de la RBCH. Análisis exploratorios de la variación genética de A. olivacea revelan la falta de estructura filogeográfica con bajos niveles de divergencia entre especímenes del sur de Chile continental, Tierra del Fuego y Cabo de Hornos.ABSTRACT: Rodentia Bowdich, 1821, is the most diverse order of mammals worldwide. Its subfamily Sigmodontinae Wagner, 1843 includes ca. 490 species, mostly distributed in the Neotropics. In Chile, the number of sigmodontine exceeds by far the diversity of other rodent groups, number of species decreases markedly toward higher latitudes. The Cape Horn Biosphere Reserve (CHBR), located at the southern end of the American continent, is home to species of abrotrichines, euneomyines, and oryzomyines, and some nominal forms belonging to these tribes, whose specific distinction has not been explored since their description. Information about the CHBR rodents is very limited, mainly anecdotal reports from explorers and naturalists of the 19th and early 20th centuries. This study offers the first general characterization the current assemblage of native rodents inhabiting the CHBR including an account of the genetic variation of the most abundant and widely distributed species in the archipelagoes at the southern end of Chile. Between 2002 and 2023, 10 expeditions have been conducted to the three national parks included in the CHBR: Alberto de Agostini, Cape Horn, and Yendegaia. During the expeditions carried out in 2023, 106 individuals were collected: Abrothrix lanosa (Thomas, 1897) (n=1), A. olivacea (Waterhouse, 1837) (n= 93) and Oligoryzomys longicaudatus (Bennett, 1832) (n=12). The Patagonian olive mouse (A. olivacea) was not only the most abundant species, but also the only one detected on the southernmost islands of the CHBR. Exploratory analyses of the genetic variation of Abrothrix olivacea reveal a lack of phylogeographic structure with low levels of divergence among specimens from southern continental Chile, Tierra del Fuego, and Cape Horn.
       
  • Descripción morfológica del comesebo grande (Pygarrhichas albogularis,
           King 1831) en la Reserva de la Biosfera Cabo de Hornos, Chile

    • Abstract: ABSTRACT: The sub-Antarctic Magellanic ecoregion is one of the most pristine wilderness areas remaining on the planet, and is home to the southernmost forest ecosystems in the world, which are protected by the Cape Horn Biosphere Reserve (CHBR). 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 (54°56'S, 67°38'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.RESUMEN: La ecorregión subantártica de Magallanes constituye una de las áreas silvestres más prístinas y alberga los ecosistemas boscosos más australes del mundo, que están protegidos por la Reserva de la Biosfera Cabo de Hornos (RBCH), Chile. En estos bosques, las aves son el grupo de vertebrados con mayor número de especies. Sin embargo, aspectos esenciales de la ecología y la morfología de varias especies de esta región todavía han sido poco investigados. Entre estas especies, se incluye el comesebo grande (Pygarrhichas albogularis, King 1831), considerado un “fósil viviente" por ser la única especie viva del género Pygarrhichas. Además, es un furnariido endémico de los bosques templados de Sudamérica. Utilizando la base de datos de 23 años del Programa de Investigación Ornitológica a Large Plazo del Parque Omora (54°56'S, 67°38'W), que ha realizado capturas y anillamientos de aves de bosque, describimos la morfología, longevidad y presencia del comesebo grande en la RBCH. Entre los años 2000 y 2022 se anillaron 91 individuos, incluyendo 29 recapturas que nos permitieron determinar que esta especie puede vivir al menos cinco años. Las medidas morfométricas mostraron una correlación positiva entre las medidas de pico y la longitud del tarso con las longitudes de la cola y del ala. El peso varió en cada estación anual, pero no significativamente. La mayor presencia al interior del bosque antiguo sugiere una dependencia de esta especie con los grandes árboles. Este estudio amplía el conocimiento sobre la historia natural del comesebo grande, particularmente de sus poblaciones que habitan en los bosques más australes del mundo.
       
  • Antecedentes sobre la historia natural de la becacina grande Gallinago
           stricklandii (Gray 1845): ¿un ave residente en cabo de Hornos'

    • Abstract: RESUMEN: La becacina grande Gallinago stricklandii (Gray, 1845J es uno de los representantes más enigmáticos de la familia Scolopacidae Rafinesque, 1815. Es la especie menos conocida del género Gallinago, y está presente en todo el ámbito de distribución del bioma de los bosques templados de Sudamérica desde la región del Maule (36°S) hasta Isla Hornos (56°S). Dentro de este ámbito biogeográfico, sus hábitos reproductivos y migratorios todavía plantean interrogantes cardinales. En este trabajo reportamos observaciones realizadas entre los años 2002 y 2023 en el Parque Nacional Cabo de Hornos, con énfasis en el período de registro más reciente en isla Hornos. En esta isla, entre enero y octubre del 2023 se registró la autoecología de un grupo familiar compuesto por dos adultos y un juvenil. Uno de los adultos fue capturado, anillado y medido en febrero del 2023 (55°58'S - 67°13'O). El grupo familiar de G. stricklandii en la isla Hornos residió allí durante las estaciones de verano, otoño, invierno y primavera. Esta conducta contrasta con el hábito migratorio de la becacina común G. magellanica (King 1828), una especie mejor conocida y simpátrica con G. stricklandii. Junto a los hábitos residentes de este grupo familiar y otros individuos de G. stricklandii, se reporta nueva información sobre la morfología, hábitos alimenticios y reproductivos en el extremo sur de su distribución. La información registrada en el extremo sur del continente americano posibilitará nuevos estudios en esta especie y sondear análisis comparativos con otras especies de la familia Scolopacidae, una familia de distribución cosmopolita que incluye a las aves reproductoras más nórdicas del mundo en el extremo boreal de América.ABSTRACT: The Fuegian snipe Gallinago stricklandii (Gray, 1845) is one of the most enigmatic members of the family Scolopacidae Rafinesque, 1815. 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.
       
  • Primer catálogo de macroalgas marinas bentónicas del canal Beagle
           occidental: Relevancia del nuevo Herbario de Criptógamas Subantárticas
           (HCS) UMAG-CHIC, Chile

    • Abstract: RESUMEN: La Reserva de Biosfera de Cabo de Hornos (RBCH) es considerada como un laboratorio natural en el extremo austral de la ecorregión subantártica de Magallanes. Los glaciares presentes a lo largo de sus canales y fiordos están hoy retrocediendo por el cambio climático global, impactando a las comunidades marinas bentónicas, particularmente a las de macroalgas. El conocimiento actual sobre esta flora marina subantártica es aún escaso y sus primeros reportes datan de los siglos XVIII y XIX. Para resolver esta brecha de conocimiento, creamos el Herbario de Criptógamas Subantárticas (HCS) con apoyo del Cape Horn International Center (CHIC) en el Laboratorio de Ecosistemas Marinos Antárticos y Subantárticos (LEMAS), Universidad de Magallanes. El HCS es el repositorio criptogámico más austral del mundo y el único portal actual del patrimonio biológico subantártico. Este catálogo da a conocer las características ecológicas y morfológicas de las macroalgas en ambientes glaciares del Canal Beagle en la RBCH y depositadas en el HCS. Se identificaron 54 especies de macroalgas, destacándose la presencia de algas Rhodophyta que representan más del 40% de la composición total y una alta riqueza de algas con talos filamentosos y/o tubulares, típica de hábitats hiposalinos. Adicionalmente, Caleta Olla se destacó por la presencia de Devaleraea yagan, aumentando su distribución hasta ahora conocida, y por ser el único sitio muestreado en contar una especie exótica invasora (Polysiphonia morrowii). A pesar de su proximidad con el Archipiélago Diego Ramírez la afinidad florística de las macroalgas del Canal Beagle es mayor con especies de hábitats protegidos, como los fiordos y canales que se encuentran al norte de la RBCH. Ante las crecientes amenazas ambientales, el HCS es esencial para evaluar cambios en la biodiversidad subantártica y establecer medidas de conservación para ecosistemas vulnerables.ABSTRACT: The Cape Horn Biosphere Reserve (CHBR) is considered as a natural laboratory at the southern end of the sub-Antarctic Magellanic ecoregion. 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. Current knowledge about this subantarctic marine flora is scarce and its first reports date from the 18th and 19th centuries. To solve this knowledge gap, we created the Sub-Antarctic Cryptogamic Herbarium (SCH) thanks to the support of the Cape Horn International Center (CHIC) in the Antarctic and Sub-Antarctic Marine Ecosystems Laboratory (LEMAS), University of Magallanes. 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 the particular focus on those species present in the CHBR. We identified 54 species, most notable of which the Rhodophyta macroalgae accounting for more than 40% of the total composition and a high species richness of algae with filamentous and/or tubular thallus, typical of hyposaline habitats. Additionally, Caleta Olla was significant for its presence of Devaleraeayagan, thereby increasing its distribution known until then, and for being the only site studied to include an exotic invasive species (Polysiphonia morrowii). Despite its geographical proximity with the Diego Ramírez Archipelago, the floristic affinity of macroalgae from the Beagle Channel is greater with that of species from well-protected habitats such as the fjords and channels of the northern part of the CHBR. In the context of the increasing environmental threats, the SCH is essential to evaluate changes in biodiversity and establish conservation measures for these vulnerable sub-Antarctic ecosystems.

  • Las colecciones biológicas de Chile deben potenciarse

    • Abstract: RESUMEN: En esta revisión abogo por la necesidad de mejorar la infraestructura de las colecciones biológicas de Chile y por el crecimiento continuo de su acervo. Para fundamentar este pedido primero doy ejemplo de algunas áreas de investigación en las que no se puede lograr nuevo conocimiento original sin el estudio de los especímenes que conforman los acervos de las colecciones. Luego comento sobre tres aspectos preocupantes de las colecciones biológicas chilenas (i.e., financiamiento deficiente, perpetuidad de las colecciones no garantizada, y bajo crecimiento de sus acervos), sugiriendo algunas vías de acción posibles de recorrer para contribuir a solucionar estos problemas. Sobre el final hago un llamado a toda la comunidad relacionada a las colecciones biológicas en hacer un esfuerzo mancomunado en pos de la mejora y crecimiento de las colecciones.ABSTRACT: In this essay I advocate the need to improve the infrastructure of the Chilean biological collections and secure their continuous growth. To support this request, I first give examples of some areas of research in which new original knowledge cannot be achieved without the study of specimens harbored in collections. Then I comment on three worrying aspects of Chilean biological collections (i.e., deficient financing, non-guaranteed perpetuity, and low growth of their holdings), suggesting some possible courses of action to follow to help solve these problems. Finally, I call on the entire community related to biological collections to make a joint effort towards the improvement and growth of the collections.
