ABSTRACT We present two new distributional country records based on previously misidentified sound recordings: Ocellated Crake, Micropygia schomburgkii (Schomburgk, 1848), in Zamora Chinchipe (Ecuador) and Rufous-faced Crake, Laterallus xenopterus Conover, 1934, in Madre de Dios (Peru). We show supporting spectrograms of sound recordings and provide tools to justify the correct identification of the trills of both species. This range extension is especially relevant for the Vulnerable L. xenopterus, representing a new important breeding site in the Bahuaja Sonene National Park, Peru.
摘要：我们提出了两个基于先前错误识别的录音的新的分布国家记录：位于厄瓜多尔萨莫拉-钦奇佩的Ocellated Crake，Micropygia schomburgkii（Schomburgk，1848）和位于秘鲁马德雷迪奥斯的Rufus face Crake，Laterallus xenopterus Conover，1934。我们展示了支持录音的声谱图，并提供了证明正确识别这两个物种颤音的工具。这一范围的扩展与脆弱的L.xenopterus特别相关，它代表了秘鲁巴胡亚松尼国家公园的一个新的重要繁殖地。

ABSTRACT Identifying patterns of herpetofaunal diversity is imperative to the conservation of these species and the ecosystems on which they rely. In this study, we determined species occurrence and composition of the herpetofauna at the Reserva de Biósfera Estación Biológica del Beni and the Chimane Reserve Indigenous Territory. Combined data resulted in documentation of 97 species belonging to 22 families and 50 genera. Reptiles were represented by 14 families and 47 species, while amphibians were represented by eight families and 50 species. This study provides a robust inventory and report of the herpetofauna at this site and delivers data that can be used in future studies. Our results indicate that this site harbors many species, which likely contributes to the collective maintenance of biodiversity in the Bolivian lowlands. Conservation initiatives should consider the collective uniqueness of vertebrate communities maintained by habitat mosaics in this area and strive to implement strategies that preserve and manage landscape-level biodiversity.
摘要:识别爬虫动物多样性模式对保护这些物种及其赖以生存的生态系统至关重要。在本研究中，我们测定了Biósfera Estación Biológica del Beni保护区和中国保护区土著领地的爬虫动物群的种类和组成。合并后的资料记录了97种，隶属于22科50属。爬虫类有14科47种，两栖类有8科50种。本研究为该地点的爬虫动物群提供了一个可靠的清单和报告，并提供了可用于未来研究的数据。我们的研究结果表明，该地点有许多物种，这可能有助于玻利维亚低地生物多样性的集体维持。保护措施应考虑到该地区由生境马赛克维持的脊椎动物群落的集体独特性，并努力实施保护和管理景观级生物多样性的战略。

ABSTRACT An annotated list of the Cicadellinae (Hemiptera: Auchenorrhyncha: Cicadellidae) of Ecuador is presented. The collection in the Museum of Zoology Invertebrates Section of the Pontifical Catholic University of Ecuador (QCAZ) is comprised of 3763 specimens of Cicadellidae of which 2806 were in the subfamily Cicadellinae. These specimens were identified as belonging to 87 species. The collection contains an additional 28 species that appear to represent undescribed species. The specimens were distributed among all provinces of Ecuador except the new, small province of Santa Elena on the coast. The specimens were from every broad geographic region of Ecuador: Coast, Western Cloud Forest, Highlands, Eastern Cloud Forest and Amazonia. Many species were collected in multiple geographic regions. There are 18 new country records in this collection. The literature was searched for additional species of Cicadellinae and an additional 166 species were identified as part of the Ecuadorian fauna for a total of 253 species. Twenty-four species have host records that indicate they have the potential to be pests of cultivated and orchard crops. Twenty-four species of Cicadellidae in 16 genera are listed for the Galápagos Islands and many are considered endemic.

ABSTRACT We describe a new species of Pristimantis from the Comunidad Río Blanco, Cordillera del Cóndor, Ecuador. Pristimantis ledzeppelin sp. nov. is characterized by a snout–vent length of 23.9–24.6 mm in adult males (n = 2) and 36.1 mm in one adult female and is compared morphologically with Pristimantis muscosus and other similar species of Pristimantis. The new species is characterized by having skin on dorsum and flanks finely tuberculate to tuberculate, a distinctive scapular fold, skin on venter coarsely areolate; snout rounded with a small rostral papilla; discs on the digits truncate, three times the width of the digits; groin and hidden surfaces of thighs yellowish-cream with distinctive brownish-black marks and/or orange irregular blotches; and coppery red iris.

ABSTRACT Vocalizations are one of the most important communication modalities in amphibian biology, and advertisement call is the type of vocalization mostly emitted by anurans (frogs and toads). In the present study, we carried out a scientometric analysis of the advertisement call in species of anurans in Colombia to determine the state of knowledge of this science in the country. We recorded the number of call descriptions and its trend throughout more than 60 years; in addition, we identified how many species there are with the call described per taxonomic family, geographic units and threat status. According to our review, between 1958 and June 30 of 2021, at least 296 studies have been published that describe the advertisement call of 307 species (of 785 in the country); only 130 descriptions come from recordings to individuals in Colombian populations. Leptodactylidae and Hylidae are the families with the highest percentage of species whose call has been described (84.6% and 68.4%, respectively). On the contrary, Bufonidae (19.5%) and Craugastoridae (12.9%) exhibit a low percentage of described calls. The Central and Eastern cordilleras were the regions with the best knowledge of advertisement calls, while the least known were the Caribbean – interAndean valleys, Orinoquía, and Sierra Nevada de Santa Marta. In terms of the threat status, the species with the least concern (LC) were the ones that presented the highest number of species with the call described. Despite an increase in the most recent two decades, our findings still reveal notable gaps in knowledge of the advertisement calls in Colombian anurans, which constitutes an incentive to develop future research on this subject. Finally, based on this meta-analysis, we highlight some recommendations that we hope that we hope stimulate new studies in ecoacoustics, using anurans in Colombia as a study model.

ABSTRACT In 2008, Ecuador recognized the Constitutional Rights of Nature in a global first. This recognition implies a major shift in the human-nature relationship, from one between a subject with agency (humans) and an exploitable object (nature), to a more equilibrated relationship. However, the lack of a standard legal framework has left room for subjective interpretations and variable implementation. The recent widespread concessioning of pristine ecosystems to mining industries has set up an unprecedented conflict and test of these rights. Currently, a landmark case involving Los Cedros Protected Forest and mining companies has reached the Constitutional Court of Ecuador. If Ecuador’s highest Court rules in favor of Los Cedros and the Rights of Nature, it would set a legal precedent with enormous impact on biological conservation. Such a policy shift offers a novel conservation strategy, through citizen oversight and action. A ruling against Los Cedros and the Rights of Nature, while a major setback for biodiversity conservation, would be taken in stride by the active social movement supporting these goals, with the case likely moving into international courts. Meanwhile, extractive activities would continue and expand, with known consequences for biodiversity.

ABSTRACT Misiones, Argentina contains the largest remnant of Upper Paraná Atlantic forest; however, half of it is unprotected. The long-term survival of its biodiversity is threatened by poaching and habitat loss, which eliminate animal populations and decrease genetic variability in species. Noninvasive techniques were used to evaluate the presence of four mammals [white-lipped peccary (Tayassu pecari), collared peccary (Pecari tajacu), tapir (Tapirus terrestris), and paca (Cuniculus paca)] often targeted by poachers. With detection dogs, 179 scats were collected across intact and modified habitats in the northern-central zones of Misiones. Of the samples collected, 76.5% (n = 137) could be genetically confirmed as one of the three targeted prey: 98 white-lipped peccaries, 13 collared peccaries, and 26 tapirs. A greater proportion of white-lipped peccary and collared peccary samples were associated with heterogeneous landscapes (74.5% and 76.9%, respectively), which contrasts with tapirs that had a higher proportion (76.9%) in native forest. While collared peccaries and tapirs had close association with protected areas (84.6% and 96.2%, respectively), over half (57.1%) of the white-lipped peccary samples were located outside of protected areas. Despite a higher proportion of survey coverage in the central zone (64.0%), the majority (81.8%) of prey samples were in the northern zone. While samples were found across habitats that varied in integrity and degree of protection, the restrictions seen among prey species distributions indicate concern for their long-term survival if the threats imposed by poaching, habitat loss, and human expansion are not controlled, especially in the central zone of Misiones.

ABSTRACT Polylepis is the dominant genus of the high Andean forest vegetation and they have a crucial ecological role. However, these forests are highly endangered and many of their biological aspects are still unknown. In this context, a series of questions were formulated with the aim that their resolution would contribute to a better understanding of Polylepis’dynamics and biological diversity, as well as improve their conservation efforts. Twenty one speakers from the V International Congress of Conservation and Ecology of Polylepis forests participated in the formulation of 67 questions related to these forests. Comments and additional information were received via email and google doc spreadsheet, open to the participants. Afterwards, two workshops were organized with the researchers to formulate, discuss, analyze and define the final list, narrowing down to a total of 40 questions. The questions were categorized into 6 different topics: Taxonomy, Ecology and Biogeography, Genetics, Conservation, Ethnobiology and Climate Change. We hope these questions will be considered as a priority for new research agendas and to define joint efforts for Polylepis forest conservation.

ABSTRACT Moriche palm (Mauritia flexuosa Linn f. [Arecaceae]) is a dominant species in the savanna margins of the Caribbean island of Trinidad. The savanna margins are frequently subjected to fires and the moriche palm, like many palm species, is adapted to cope with a degree of fire damage. These palms also frequently host large termite nests that tend to burn during fires, which causes further damage to the palm stems. This paper explores the possibility that the combination of termite nests and frequent fires can increase tree mortality. Two post-fire surveys were conducted to record, evidence of fire exposure, fire damage to termite nests and fire damage to palm stems. In both surveys, the majority of palms with termite nests suffered fire damage to their stems, while none of the termite-free palms showed damage. Furthermore, a comparison of nest size and damage to the bark showed stems with larger nests had significantly more damage than those with smaller or no nests. The results suggest that the presence of termite nests increases the extent of fire damage to palm trunks by providing a point of combustion that focuses flames on the already compromised stem tissue. Long-term studies are warranted to investigate the impact of repeated fires on wild arborescent palm populations.
摘要：莫里切棕榈（Mauritia flexuosa Linn f.〔Arecaceae〕）是加勒比海特立尼达岛热带草原边缘的优势物种。稀树草原边缘经常受到火灾的影响，莫里奇棕榈和许多棕榈物种一样，能够适应一定程度的火灾破坏。这些棕榈树还经常有大型白蚁巢，在火灾中容易燃烧，这会对棕榈茎造成进一步的破坏。本文探讨了白蚁巢穴和频繁火灾相结合会增加树木死亡率的可能性。进行了两次火灾后调查，以记录火灾暴露、白蚁巢穴火灾损坏和棕榈茎火灾损坏的证据。在这两项调查中，大多数有白蚁巢穴的棕榈树的树干都受到了火灾的破坏，而没有白蚁的棕榈树受到了破坏。此外，对巢穴大小和树皮损伤的比较表明，巢穴较大的树干比巢穴较小或没有巢穴的树干损伤更大。研究结果表明，白蚁巢穴的存在通过提供一个燃烧点来将火焰集中在已经受损的树干组织上，从而增加了对棕榈树干的火灾破坏程度。有必要进行长期研究，以调查反复火灾对野生树栖棕榈种群的影响。
