  • Inocybe brijunica sp. nov., a New Ectomycorrhizal Fungus from Mediterranean Croatia Revealed by Morphology and Multilocus Phylogenetic Analysis
Title: Inocybe brijunica sp. nov., a New Ectomycorrhizal Fungus from Mediterranean Croatia Revealed by Morphology and Multilocus Phylogenetic Analysis
A new ectomycorrhizal species was discovered during the first survey of fungal diversity at Brijuni National Park (Croatia), which consists of 14 islands and islets. The National Park is located in the Mediterranean Biogeographical Region, a prominent climate change hot-spot. Inocybe brijunica sp. nov., from sect. Hysterices (Agaricales, Inocybaceae), is described based on morphology and multilocus phylogenetic data. The holotype collection was found at the edge between grassland and Quercus ilex forest with a few planted Pinus pinea trees, on Veli Brijun Island, the largest island of the archipelago. It is easily recognized by a conspicuous orange to orange–red–brown membranaceous surface layer located at or just above the basal part of the stipe. Other distinctive features of I. brijunica are the medium brown, radially fibrillose to rimose pileus; pale to medium brown stipe with fugacious cortina; relatively small, amygdaliform to phaseoliform, and smooth basidiospores, measuring ca. 6.5–9 × 4–5.5 µm; thick-walled, utriform, lageniform or fusiform pleurocystidia (lamprocystidia) with crystals and mostly not yellowing in alkaline solutions; cheilocystidia of two types (lamprocystidia and leptocystidia); and the presence of abundant caulocystidia only in the upper 2–3 mm of the stipe. Phylogenetic reconstruction of a concatenated dataset of the internal transcribed spacer region (ITS), the nuclear 28S rRNA gene (nrLSU), and the second largest subunit of RNA polymerase II (rpb2) resolved I. brijunica and I. glabripes as sister species.  more » « less

    The family Inocybaceae has been poorly studied in Africa. Here we describe the first species of the genus Mallocybe from West African and Zambian woodlands dominated by ectomycorrhizal trees of Fabaceae and Phyllanthaceae. The new species M. africana is characterized by orange-brown fruitbodies, a fibrillose pileus, a stipe tapered towards the base and large ellipsoid basidiospores. It resembles many north and south temperate species of Mallocybe but is most closely related to the southeast Asian tropical species, M. errata. M. africana is widely distributed in West Africa (Benin, Togo, Burkina Faso and Ivory Coast) extending to South-eastern Africa in Zambia. Phylogenetic analyses based on 5.8S rDNA, nLSU and RPB2 sequence data confirm that M. africana is nested within Mallocybe. A complete morphological description and illustrations, including photographs and line drawings, are presented.

    Rüppell's vultures are critically endangered, primarily due to anthropogenic activities such as habitat degradation, climate change, and intentional and unintentional poisoning, which have led to the loss of nesting and breeding sites. To aid in the conservation and protection of these species, habitat evaluation and niche mapping are crucial. Species distribution modeling (SDM) is a valuable tool in conservation planning, providing insights into the ecological requirements of species under conservation concerns. This study employed an ensembling modeling approach to assess the habitat suitability and distribution of Rüppell's vultures across Kenya. We utilized four algorithms; Gradient Boosting Machine, Generalized Linear Model, Generalized Additive Model, and Random Forest. Data on Rüppell's vultures were sourced from the Global Biodiversity Information Facility, while key environmental variables influencing the species' distribution were obtained from WorldClim. The resultant species distribution map was overlaid with a conservation area map to evaluate the overlap between suitable habitats and existing protected areas. Our analysis identified suitable habitats in regions such as the Masai Mara Game Reserve, Mount Kenya National Park, Nairobi National Park, Tsavo East National Park, and Hell's Gate National Park, with the majority of these habitats located outside protected areas, except those within Hell's Gate National Park. Precipitation and elevation emerged as the primary environmental predictors of the distribution of Rüppell's vultures. Based on these findings, we recommend establishing vulture sanctuaries in suitable habitats and hotspots to enhance the conservation of Rüppell's vultures outside the protected areas.

    Abstract Madagascar's lemurs are threatened by forest loss, fragmentation, and degradation. Many species use flexible behaviors to survive in degraded habitat, but their ability to persist in very small areas may be limited. Insular lemurs, like those found on Nosy Be, an island off the northwestern coast of Madagascar, are at heightened risk of sudden population declines and extirpation. Nosy Be is home to two Critically Endangered species—the endemic Nosy Be sportive lemur (Lepilemur tymerlachsoni) and Claire's mouse lemur (Microcebus mamiratra)—as well as the Endangered black lemur (Eulemur macaco). Most of the remaining forest on Nosy Be is protected by the 862‐ha Lokobe National Park. To document how Nosy Be lemurs use their restricted habitat, we conducted vegetation and reconnaissance surveys on 53 transects in and around Lokobe. We collected data on tree size, canopy cover, understory visibility, and elevation for 248 lemur sightings. We used a spatially explicit, multi‐species occupancy model to investigate which forest‐structure variables are important to lemurs. Our results represent some of the first data on habitat use by insular lemurs. Black lemurs preferred significantly larger trees and areas with less dense understory. They also occurred significantly less outside of Lokobe National Park, even when accounting for sampling effort and geography. The distributions of the sportive and mouse lemurs were not related to the forest structure variables we documented, but they did negatively predict each other—perhaps because their habitat requirements differ. These results also underscore the importance of the national park to protecting the black lemur population on Nosy Be and raise questions about what factors do influence the distribution of Nosy Be's smaller lemurs. Close monitoring is needed to prevent these populations and the ecosystem services they provide from disappearing, as have other island lemurs.

    Born and raised in a remote region of Colombia, a South American country dominated by lush tropical rainforests and FARC guerrillas (Revolutionary Armed Forces of Colombia), I never imagined spending my summers in Greece amongst picturesque olive groves and tourists, much less conducting research on one of its islands. Since 2013, I have had the opportunity to spend eight weeks every summer on the island of Lesbos, the third largest island in the Aegean Sea. However, this island is not just like the other Greek islands we all see on television and pamphlets in tourist agencies; it offers more than the lovely white houses with blue accents tightly packed on a foothill facing a turquoise sea. The research experiences on this island are also not comparable with any of those I have had in other international locations. Lesbos is only about two times the surface area of New York City but is biologically highly diverse. This volcanic island is situated only 9 km from the Turkish coast and has multiple natural ecosystems and agroecosystems including wetlands, chestnut and oak forests, and olive groves. Due to its vicinity to the Asian continent, it supports species of animals and plants from both the Mediterranean region and Asia. In the spring and fall, flocks of migrant birds from Africa are captured by the lenses of photographers and amateur birdwatchers who move like ants throughout the island. More than 20 million years ago, several species of trees covered parts of Lesbos, but today, only their petrified forms remain as evidence of this ancient diversity.

    Papuan snakes of the genus Aspidomorphus have long been taxonomically problematic, but nomenclature within this group has been stable at three recognized species since 1967. Previous genetic work suggested the presence of a number of cryptic but currently unrecognized candidate species in the genus. In 2004, I obtained a series of Aspidomorphus from Sudest Island, Milne Bay Province, Papua New Guinea that were clearly different from currently recognized species, and I describe that species here as A. dimorphus sp. nov. This species exhibits a striking bimodality in color pattern in adults, here termed the “orange morph” and “dark morph”. This dimorphism is not related to sex, and both forms have earlier been shown to be genetically identical. Description of A. dimorphus sp. nov. begins the process of bringing taxonomic clarity to a genus long held in the grip of nomenclatural stasis. It furthermore highlights again the importance of Sudest Island for biodiversity endemism.
