Since the last update of the list of the Spanish herpetofauna in 2018, recent studies have provided new evidence supporting the need to implement taxonomic changes in several groups. In this work, we present an updated reference list for the Spanish herpetofauna, which currently includes 132 native or historically introduced species, i.e. 37 amphibians and 95 reptiles, offering a standardized framework for amateurs, scientists, and environmental agencies. While updating the list, we had to undertake some nomenclatural acts. For instance, to solve the nomenclatural issues concerning Blanus species, we designate a neotype for Amphisbaena oxyura Wagler, 1824; thus, the valid name for the two recognized Iberian species are Blanus cinereus and Blanus oxyurus. We also provide an updated list for the 13 introduced species with documented breeding populations in Spain.

  • Guillaume Ghisbain + 19 more

At a time when nature conservation has become essential to ensure the long-term sustainability of our environment, it is widely acknowledged that conservation actions must be implemented within a solid taxonomic framework. In preparation for the upcoming update of the IUCN Red List, we here update the European checklist of the wild bees (sensu the IUCN geographical framework). The original checklist, published in 2014, was revised for the first time in 2017. In the present revision, we add one genus, four subgenera and 67 species recently described, 40 species newly recorded since the latest revision (including two species that are not native to Europe), 26 species overlooked in the previous European checklists and 63 published synonymies. We provide original records for eight species previously unknown to the continent and, as original taxonomic acts, we provide three new synonyms, we consider two names as nomina nuda, ten names as nomina dubia, three as species inquirenda, synonymize three species and exclude 40 species from the previous checklist. Around a hundred other taxonomic changes and clarifications are also included and discussed. The present work revises the total number of genera for IUCN Europe to 77 and the total number of species to 2,138. In addition to specifying the taxonomic changes necessary to update the forthcoming Red List of European bees, we discuss the sampling and taxonomic biases that characterise research on the European bee fauna and highlight the growing importance of range expansions and species invasions.

An updated checklist of the wild silkmoths (Lepidoptera, Saturniidae) of Colombia
  • Sep 7, 2023
  • ZooKeys
  • Lorenzo Comoglio + 1 more

In recent years, the study of wild silkmoths (Lepidoptera: Saturniidae) has increased exponentially due to the intense sampling effort and the use of molecular evidence for species delimitation, which led to the description of numerous new taxa especially from the Neotropic. Given these rapid advances, the checklist of the Colombian Saturniidae needs to be updated to cover the taxonomy, distribution, and diversity of these moths in the country. After an extensive review of literature, data repositories, and collections, an updated and comprehensive list of Saturniidae from Colombia is presented, including their occurrence status in each Colombian department. The checklist includes 7 subfamilies, 55 genera, and 790 taxa (766 in species rank) of Saturniidae in Colombia. Current distribution data show that the genus Winbrechlinia, the subgenusDarylesia, 379 species, and 18 subspecies are endemic to Colombia. Moreover, a dichotomic key to the Colombian subfamilies is provided. A few taxonomic changes are proposed based on a thorough taxonomic revision of the Colombian taxa. This revision also addresses the issue of outdated species names reported in the first checklist of Colombian Saturniidae (Amarillo-Suárez 2000) and excludes old records of taxa that are considered dubious for Colombia based on new evidence. By presenting an updated list of Colombian species, including the newly described taxa, this study aims at eliminating confusion stemming from outdated names and provides a useful resource for researching and conservating Saturniidae in Colombia. We wish to offer a common reference for future studies on the biodiversity and biogeography of moths in the Neotropical realm.

  • José D Ramírez-Fernández + 4 more

Mammal diversity in Costa Rica is considerably high given the size of the country (51,100 km2), and has increased in recent years. Taxonomic changes together with distribution extension records have contributed to such an increase. Here we present the revised and updated list of mammals confirmed for Costa Rica based on previous lists and recent additions obtained from literature, with notes on endemism and conservation status. This updated list was based on Rodríguez-Herrera et al. (2014a) list, compared and matched with the most updated taxonomic review. A total of 256 mammals are now confirmed for Costa Rica, with the order Chiroptera and Rodentia as the most representative. We report 30 endemics for Costa Rica, including those species whose distribution is limited to the country and one of its two neighboring countries, from which 21 are rodents. Compilation on conservation status information reveals 29.6 % of species within the list classified as threatened, either by Costa Rican or international environmental authorities. Increase in new studies on mammals all around the world is leading to the discovery of new species. While systematic and phylogenetic revisions is revealing new taxonomic relationships, and cryptic species. Mainly on highly diverse and taxonomically challenging groups, as bats, rodents, and shrews, as we evidence here. Several threatened and endemic species occur in Costa Rica, where the greatest endemism area is the high elevations, and most endemic species are mice. The creation and establishment of protected areas in a large part of the Costa Rican territory has favored the prevalence of a diverse mammalian assemblage.

Band Teacher Agency in a High-Stakes Performance Environment
  • Apr 8, 2022
  • Journal of Research in Music Education
  • Olivia G Tucker

The purpose of this instrumental case study was to investigate band teacher agency in a high-stakes performance environment. Research questions were: (1) What experiences and professional relationships were most salient in the past (iterative), present (practical-evaluative), and future (projective) dimensions of band teacher agency in a high-stakes performance environment? and (2) How did high-stakes performance practices, mediated by teacher agency, shape music teaching and learning in school bands? I used Emirbayer and Mische’s chordal triad of agency and Priestley et al.’s ecological framework of teacher agency as theoretical frameworks, and I collected data in the forms of interviews, observations, and document review in 2019. Participants’ agency emerged from their interactions with music education organizations that perpetuated a high-stakes performance environment. Powerful structures (state associations) and individual agents (band teachers) sustained each other through norms and values derived from their contextual discourse. Findings indicated that visions for holistic music-making and greater diversity and inclusion in school music must include structural changes in professional organizations. For example, state associations could enact policies that incentivize teachers to exert agency to engage students in other forms of music learning in addition to performance preparation.

Peixes da planície de inundação do alto rio Paraná e áreas adjacentes: revised, annotated and updated
  • Jun 11, 2018
  • Neotropical Ichthyology
  • Renata Rúbia Ota + 3 more

The book “Peixes da planície de inundação do alto rio Paraná e áreas adjacentes” represents the most cohesive data compilation for the rio Paraná floodplain. However, considering the dynamicity of the taxonomy of freshwater fishes, several new records and taxonomic changes occurred along the past years. Therefore, the results of that publication were revisited, providing an update of the species list, their taxonomic status, records and geographic distribution, and also new keys for genera and species. The species included were those recorded in the rio Paraná basin, from the mouth of the rio Paranapanema to the Itaipu Reservoir, following the general methodology presented in the book. A total of 10 orders, 41 families, 126 genera, and 211 species were registered, with an increase of one order, six families, 14 genera, and 29 species when compared to the book. Additionally, four new genera recently described, five synonymization proposals, 14 new identifications, four new combinations, 12 new species recently described, 34 new records, and nine misidentified species were recorded. These results are associated with the redirection of human and financial resources to that area, which enabled monitoring and intensive exploration of its watercourses; as well as training of taxonomists, and new taxonomic resolutions.

Recent Progress in Taxonomic Studies, Biogeographic Analysis, and Revised Checklist of Reptiles in Indochina
  • Oct 7, 2023
  • Russian Journal of Herpetology
  • Nikolay A Poyarkov + 8 more

The Indochinese Peninsula represents one of the key global biodiversity hotspots in Southeast Asia. The herpetofauna of Indochina (herein including Vietnam, Laos, Cambodia, and Thailand) currently (as by 10 August 2023) comprises 882 native and six invasive species of reptiles and is one of the richest in the world. About 40% of the Indochinese reptile species were discovered or recorded within the first two decades of the 21st century. We review the literature and our field data to assess all recent discoveries and taxonomic changes; we compile an annotated checklist of reptilian fauna of Indochina, including updated faunal lists for Vietnam and Thailand. Reptile species checklists for Laos and Cambodia are published for the first time. For each species we provide the following information: scientific name; recommended common name in English; information on type specimens; information on recognized subspecies; type locality; data on its distribution within Indochina and beyond; IUCN conservation status; taxonomic comments and the most important references. We review the distribution of each reptilian species across the 23 biogeographic subregions of Indochina, estimate the similarity among the regional faunas and evaluate their species richness and endemism. In total, we record 882 native reptile species belonging to three orders, 34 families and 163 genera; of them 408 species (46.3%) are endemic to Indochina. Comprising 512 known species, the reptilian fauna of Thailand is the richest (114 country endemics, 22.3%), followed by Vietnam with 496 species (157 endemics, 31.7%), Laos with 250 species (39 endemics, 15.6%), and Cambodia with 191 species (15 endemics, 7.9%). A cluster analysis of faunal similarity between the subregions revealed three major groupings, corresponding to the Sundaland fauna south of the Isthmus of Kra, the subtropical fauna of northeastern Indochina, and the tropical fauna of mainland Indochina. Within the latter grouping four clusters can be distinguished: (1) northern, central and southern Annamites, (2) western Indochinese subregions, (3) central-south Vietnam lowlands including the Bolaven Plateau and Cardamom Mountains, (4) and the depleted faunas of river deltas, coastal areas and offshore islands. We identify the Northern, Central and Southern Annamites, the Northwest Uplands of Vietnam, Laos and Thailand, Southern Tenasserim in Thailand as the major centers of reptilian diversity in Indochina. The highest number of Indochinese endemic reptilian species was recorded in Central-Southern Vietnam Lowlands, Northern Annamites, and Central Annamites. The analysis of reptilian distribution patterns suggests the presence of 20 clusters of species sharing similar distribution patterns across Indochina. Our results further underline the key role of Indochina as an important area for diversity and conservation of reptiles. Among 882 native species of Indochinese reptiles, 356 species (40.4%) are considered as Data Deficient (DD) or were Not Evaluated (NE) according to the IUCN Red List criteria, while 106 species (12.0%) were considered Vulnerable (VU), Endangered (EN) or Critically Endangered (CR), 17 species (1.9%) were considered to be Near Threatened (NT), and 403 species (45.7%) to be of the Least Concern (LC) status. Our work has implications for elaboration of further conservation efforts for Indochinese reptiles on regional and global levels, as well as for a better understanding of the biogeographic patterns of reptilian richness and endemism in Asia.

Recent Progress in Taxonomic Studies, Biogeographic Analysis, and Revised Checklist of Amphibians in Indochina
  • Jun 24, 2021
  • Russian Journal of Herpetology
  • Nikolay A Poyarkov + 7 more

The Indochinese Peninsula is recognized as one of the key global biodiversity hotspots. The amphibian fauna of Indochina (including Vietnam, Laos, Cambodia and Thailand) is one of the richest in the world. About 60% of the known species were described within the last 20 years. We review the literature and our data to assess all recent discoveries and taxonomic changes and compile the first annotated checklist of the amphibian fauna of Indochina since the middle of the 20th century, including updated faunal lists for Vietnam and Thailand. Amphibian checklists for Laos and Cambodia are published for the first time. For each species we provide the following information: scientific name; recommended common name in English; information on type specimens; type locality; data on its distribution within Indochina and beyond; IUCN conservation status; taxonomic comment and the most important references. We review the distribution of each species across the 23 biogeographic subregions of Indochina, estimate the similarity among the regional faunas and evaluate their species richness and endemism. In total we record 423 amphibian species belonging to three orders, 11 families and 71 genera; 199 species (47%) are endemic to Indochina. Comprising 270 known species, the amphibian fauna of Vietnam is the richest (98 endemics, 36.3%), followed by Thailand with 194 species (29 endemics, 14.9%), Laos with 121 species (13 endemics, 10.7%), and Cambodia with 72 species (6 endemics, 8.3%). A cluster analysis of faunal similarity between the subregions shows two major assemblages, divided by the Isthmus of Kra. Within the northern mainland portion of Indochina three clusters can be distinguished: (1) northeastern and northwestern uplands of Vietnam and northern Laos; (2) Northern, Central, and Southern Annamites, the Bolaven Plateau, and central-south Vietnam lowlands; (3) western Indochinese subregions. We identify the Northeast and Northwest Uplands of Vietnam, the Northern, Central and Southern Annamites, the Cardamom Mountains, the mountains of Northeast Thailand, Northern Tenasserim and southern Peninsular Thailand as nine major centers of diversity and endemism of Indochinese amphibians. The analysis of amphibian distribution patterns across Indochina suggests the presence of 14 chorotypes grouped in five major range types. Our results underline the role of Indochina as a key area for amphibian diversity and conservation. Among 423 species of Indochinese amphibians, 152 species (35.9%) were considered as data deficient (DD) or were not evaluated (NE) according to the IUCN Red List criteria; while 76 species (18.0%) were considered vulnerable (VU), endangered (EN) or critically endangered (CR), 20 species (4.7%) were considered to be near threatened (NT), and 175 species (41.4%) to be of the least concern (LC). Our study thus has implications for further conservation efforts on regional and global levels, as well as for understanding the biogeographic patterns of amphibian richness and endemism in Asia.

Challenging norms, protecting forests: The agency and negotiation strategies of women rangers in Aceh, Indonesia
  • Sep 30, 2025
  • GENDER EQUALITY: International Journal of Child and Gender Studies
  • Rizkika Lhena Darwin + 5 more

This research analyzes the strategic agency of Mpu Uteun, a women-led conservation group in Aceh, Indonesia, that emerged in response to severe environmental degradation within a patriarchal social context. Grounded in the theoretical framework of women's agency and empowerment, this research examines the negotiation mechanisms that these female forest guardians employ across multiple spheres—domestic, communal, economic, and state—to legitimize their roles in environmental governance as they navigate socio-cultural barriers. Conducted within a qualitative design, this research employed secondary data examined through thematic narrative analysis. The findings revealed that the agency of Mpu Uteun is rooted in a collective experience of ecological disaster, which motivates proactive conservation measures such as forest patrols, reforestation, and disaster mitigation. The group's success hinges on sophisticated negotiation strategies: they renegotiated domestic roles to accommodate public activism, navigate communal resistance through inclusive tactics and non-confrontational approaches toward illegal loggers, and, crucially, secure formal legitimacy from the state by obtaining a customary forest management permit. This research concludes that Mpu Uteun exemplifies an effective model of community-based conservation while fundamentally transforming the gendered landscape of natural resource governance. Thus, this research advances understanding of women’s environmental agency, demonstrating how strategic negotiation dismantles patriarchal barriers and informs inclusive conservation policy.

A new checklist of the bryophytes of Britain and Ireland, 2020
  • Jan 2, 2021
  • Journal of Bryology
  • T L Blockeel + 6 more

Introduction. Many taxa have been added to the bryophyte flora of Britain and Ireland since the publication of the previous checklist in 2008. This has coincided with numerous taxonomic and nomenclatural changes in the European flora, especially as a consequence of molecular sequencing. With the publication of a new European checklist in 2020 it is now appropriate to provide an updated and annotated list for Britain and Ireland. Methods. A working group was convened to consider and reach a consensus on taxonomic and nomenclatural matters arising from the European checklist. Special consideration was given to the citation of the authors of names. Taxa reported as new to Britain and Ireland since the previous checklist in 2008 were incorporated. Key results. A new checklist of bryophytes (hornworts, liverworts and mosses) is presented. Based on the taxonomy adopted in the checklist, the bryophyte flora of Britain and Ireland comprises four hornworts (Anthocerotophyta), 299 liverworts (Marchantiophyta), and 795 mosses (Bryophyta) at species rank, with 42 additional infraspecific taxa.

Tree Diversity in Nepal: An updated list
  • Aug 15, 2024
  • Journal of Plant Resources
  • Tirtha Raj Pandey

Trees are one of the dominant life forms in plant world. They have important ecological and commercial roles in society. Nepal is also rich in terms of tree species diversity; however, a comprehensive country-wide inventory is still in need. This paper aims to document the occurrence of native and naturalized tree species of the country with updated information on their identification and nomenclatural issues. Extensive database searches including the ‘Global Tree Search’ and consultation of many publications has revealed the occurrence of 700 taxa of trees belonging to 90 families, 300 genera and 688 species in Nepal. During the study, 8 species of trees are found as endemic to Nepal, while 8 other tree species are naturalized in the country. Knowing the diversity and distribution of tree species will help in the formulation of their conservation strategy and estimation of their ecological value.

Revisión de las avispas figítidas fósiles (Insecta: Hymenoptera: Cynipoidea) descritas de depósitos de compresión durante la primera mitad del siglo XX
  • Jun 30, 2019
  • Estudios Geológicos
  • J Pujade-Villar + 1 more

En la presente investigación se revisan los holotipos de las avispas fósiles del Cenozoico atribuidas a la familia Figitidae, las cuales fueron descritas en la primera mitad del siglo XX por Charles T. Brues y Georg Statz provenientes de los yacimientos de Florissant (EE.UU.) y Rott-am-Siebengebirge (Alemania), respectivamente. Se proponen los siguientes cambios taxonómicos: Palaeogronotoma? sola (Brues) n. comb., Aulacidea rotundata (Statz) n. comb., A. plana (Statz) n. comb. y A. spiniger (Statz) n. comb. Los cambios taxonómicos para las tres últimas especies indicadas han implicado su emplazamiento en el género actual Aulacidea, de la familia Cynipidae, y por lo tanto no pertenecen a la familia Figitidae como se consideró originalmente en 1938. La revisión de una especie fósil originalmente descrita en 1919, conservada en ámbar báltico, muestra que posee un conjunto único de caracteres para la familia Cynipidae, permitiendo la descripción de una nueva tribu: Kinseycynipsini n. tribe. Se hacen indicaciones taxonómicas referidas a otras tres especies de cinípidos fósiles. La adscripción taxonómica correcta de las especies fósiles de figítidos y cinípidos descritas hace alrededor de un siglo es importante para entender la evolución de estas dos familias de cinipoideos, las cuales desempeñan un importante papel ecológico en los ecosistemas terrestres actuales. También se proporcionan listas actualizadas de las especies fósiles de figítidos y cinípidos conocidas.

The Epipactis helleborine Group (Orchidaceae): An Overview of Recent Taxonomic Changes, with an Updated List of Currently Accepted Taxa.
  • Sep 4, 2021
  • Plants
  • Zbigniew Łobas + 3 more

The Epipactis helleborine (L.) Crantz group is one of the most taxonomically challenging species complexes within the genus Epipactis. Because of the exceptionally high levels of morphological variability and the ability to readily cross with other species, ninety different taxa at various taxonomic ranks have already been described within its nominative subspecies, but the taxonomic status of most of them is uncertain, widely disputed, and sometimes even irrelevant. The present review is based on results of the most recent research devoted to the E. helleborine group taxonomy. In addition, we analysed data about taxa belonging to this group presented in some research articles and monographs devoted directly to the genus Epipactis or to orchids in certain area(s). Based on the reviewed literature and data collected in four taxonomic databases available online, we propose an updated list of the 10 currently accepted taxa in the E. helleborine group (two species, six subspecies, and two varieties), which includes E. helleborine (L.) Crantz subsp. helleborine; E. helleborine subsp. bithynica (Robatsch) Kreutz; E. helleborine subsp. distans (Arv.-Touv.) R.Engel and P.Quentin; E. helleborine subsp. neerlandica (Verm.) Buttler; E. helleborine var. tangutica (Schltr.) S.C.Chen and G.H.Zhu; E. helleborine subsp. tremolsii (Pau) E.Klein; E. helleborine subsp. voethii (Robatsch) Jakubska-Busse, Żołubak, and Łobas, stat. nov.; E. condensata Boiss. ex D.P.Young; E. condensata var. kuenkeleana (Akhalk., H.Baumann, R.Lorenz, and Mosul.) Popovich; and E. cupaniana C.Brullo, D’Emerico, and Pulv.
