Summary: This study is the first of a series focusing on the taxonomy and systematics of Carex in South America, specifically the 24 species of Carex subgenus Vignea with androgynous spikes. Using phylogenetic analysis with barcode markers, the study found that most lineages colonized South America during the Plio-Pleistocene from North America, except for a local radiation of species dating back to the Late Miocene. The study also included new typifications and the description of a new species, Carex pedicularis.

Summary: Three new species of Myoplatypus are described in this article, along with the transfer and synonymization of several other species. Male specimens of all species are illustrated, and a key to all species is provided. The discovery of these new species expands our knowledge of Myoplatypus, especially with the first records of the genus in South America. Due to their limited distribution and scarcity, conservation attention may be needed for these pinhole borer species.

Summary: This study describes ten new species of the Virola genus, which were mainly discovered through herbarium specimens collected in the 1980s and 1990s. These new species come from Colombia, Ecuador, Peru, and Brazil, and a comparison table with morphologically similar species is provided.

Summary: Neglected tropical diseases pose a global threat to public health, particularly in underdeveloped countries. This study examines the occurrence of zoonotic helminths in two species of wild canids in Colombia, the bush dog and the crab-eating fox. The findings reveal the presence of canine-specific tapeworms, Spirometra mansoni cestodes, and Lagochilascaris cf. minor nematodes in these canid species, highlighting the need for monitoring and understanding the epidemiology of these neglected diseases in South America.

Summary: This article describes three new species of Carex sect. Fecundae (Cyperaceae) from Central America: Carex orothanatica from Costa Rica, Carex siguanabae occurring in El Salvador and Honduras, and Carex via-aquae from Costa Rica and Panama. The study compares the three new species with their relatives and provides lectotypification for two related names, Carex lehmanniana Boott, and C. lehmaniana var. simplex Kuk.

Summary: In this study, phylogenetic analyses were conducted on Perenniporia species and related genera using DNA sequences of multiple loci. It was found that the genus Perenniporia is polyphyletic. Based on morphology and phylogeny, 15 new genera were proposed, 2 new species were described, and 37 new combinations were proposed. Illustrated descriptions of the new species were provided, along with identification keys to Perenniporia and its related genera.

Summary: We studied the species limits and taxonomy of the slaty-backed nightingale-thrush Catharus fuscater (Passeriformes: Turdidae), a polytypic complex of songbirds with a broad montane distribution in Central and South America, using datasets of genetic and phenotypic characters. We found 10 allopatric populations that have evolved independently for multiple glacial cycles. Genetic structure is correlated with divergence in phenotypic characters, including plumage colour, iris colour, maxilla (bill) colour, and the acoustic structure of vocalizations. Based on our findings, we propose a taxonomic revision that recognizes seven species in the complex, including a newly described species from eastern Panama, and four subspecies, two of which are newly described.

Summary: In this study, a new species, Agaricus macrochlamys, was described, which is morphologically cryptic with the edible and medicinally cultivated mushroom A. subrufescens. Phylogenetic analyses showed a close relationship between A. macrochlamys and A. subrufescens, with species-specific markers distinguishing them. Additionally, while A. subrufescens is cosmopolitan, A. macrochlamys is currently limited in distribution.

Summary: The transition between tropical savanna and humid forest is mainly influenced by the average duration of dry and wet spells and the interaction between these variables, with total monthly precipitation having a marginal effect. Dry spell duration has the largest effect on the probability of forest occurrence, decreasing by 7.5% for each additional consecutive dry day. Wet spell duration also impacts forest occurrence, increasing by 4.1% for each additional consecutive wet day.

Summary: The male of the wolf spider Paratrochosina arnica was redescribed, and the female of this species was described for the first time. The phylogenetic position of P. arnica was evaluated using mitochondrial genes, revealing three different morphotypes based on colour patterns with no differences in genitalic features between males and females. Genetic and taxonomic results supported that the three morphotypes are conspecific.

Summary: Climate change poses a significant threat to biodiversity, with tropical biodiversity expected to be most impacted. This study evaluates the risk projections for different aspects of biodiversity in Central and South America (CSA) and the potential benefits of climate change mitigation. The findings suggest that up to 85% of risk projections predict negative impacts, with species extinctions projected in 26% of cases. However, mitigation efforts in line with the Paris Agreement could substantially reduce risks by over 80%, emphasizing the importance of adaptation measures for endemic species in CSA.
