Genetic data improve the assessment of the conservation status based only on herbarium records of a Neotropical tree

Background and Aims: Gustavia sessilis is a neotropical tree, belonging to the Lecythidaceae family, until now known from the Colombian Chocó region only. In this paper, we report G. sessilis for the first time for Central America. Methods: Central American specimens of G. sessilis were collected in 2019 from the Darién Province (eastern Panama). Plant identifications were confirmed by comparing collected specimens with those identified earlier and housed in the MO, PMA, SCZ and UCH herbaria. Type specimens were examined by consulting the JSTOR Global Plants database. The estimations of the conservation status were made based on the criteria of the IUCN.Key results: The record of G. sessilis for Central America is presented, based on a collection made from eastern Panama (Darién Province). Photographs, taxonomic comments, and conservation notes are provided. Additionally, a key for the Central American Gustavia species is included.Conclusions: The distribution of G. sessilis now ranges from Bahía Piñas, Darién Province, Panama to the Condoto river, Chocó region, Colombia, highlighting the importance of the Chocó Panama-Colombia region for the conservation of biodiversity, since it could act as a natural corridor for species. Taking into account the small number of records and the restricted natural range of this species, we recommend considering G. sessilis as an endangered species.

Molecular Genetic Data

We revise the species of green anoles (i.e., the species related to Anolis aliniger, A. chlorocyanus, and A. coelestinus) occuring on Hispaniola. Based on our analyses of morphological and molecular genetic data we recognize 16 species of green anoles, eight of which we describe as new species (A. apletolepis sp. nov., A. chlorodius sp. nov., A. divius sp. nov., A. eladioi sp. nov., A. gonavensis sp. nov., A. leucodera sp. nov., A. prasinorius sp. nov. and A. viridius sp. nov.) and three of which are raised from subspecific to species level (A. cyanostictus, A. demissus and A. pecuarius) and one is resurrected from synonymy with A. chlorocyanus (A. peynadoi). Because the six syntypes of A. chlorocyanus (MNHN 785, 787, 2007.2066–09) are conspecific with the only available syntype of A. coelestinus (i.e., MCZ 3347), we have petitioned the International Commission of Zoological Nomenclature (ICZN) to use its plenary power to set aside the type status of the syntypes of Anolis chlorocyanus and to allow the designation of a neotype in order to stabilize the current and long established usage of the names A. chlorocyanus and A. coelestinus. For each species we provide a standardized description of external morphology, color descriptions in life, color photographs in life, description and illustration of hemipenis morphology (if available), distribution maps based on the specimens examined, comments on the conservation status, and natural history notes. Finally, we provide a dichotomous key for the identification of the 16 species of green anoles occuring on Hispaniola.

We revise the species of Audantia, a genus of dactyloid lizards endemic to Hispaniola. Based on our analyses of morphological and genetic data we recognize 14 species in this genus, four of which we describe as new species (A. aridius sp. nov., A. australis sp. nov., A. higuey sp. nov., and A. hispaniolae sp. nov.), and two are resurrected from the synonymy of A. cybotes (A. doris comb. nov., A. ravifaux comb. nov.). Also, we place Anolis citrinellus Cope, 1864 in the synonymy of Ctenonotus distichus (Cope, 1861); Anolis haetianus Garman, 1887 in the synonymy of Audantia cybotes (Cope, 1863); and Anolis whitemani Williams, 1963 in the synonymy of Audantia saxatilis (Mertens, 1938). Finally, we designate a lectotype for Anolis cybotes Cope, 1863, and for Anolis riisei Reinhardt & Lütken, 1863. Our main focus is on the populations of anoles formerly referred to as Audantia cybotes which we demonstrate to be a complex of seven distinct species. For these seven species we provide a standardized description of external morphology, color descriptions in life, color photographs in life, description and illustration of hemipenis morphology (if available), distribution maps based on the specimens examined, comments on the conservation status, and natural history notes. Finally, we provide a dichotomous key for the identification of the 14 species of the genus Audantia occuring on Hispaniola.

Conservation Concern

The number of effective breeders (Nb) has been touted as a means to monitor freshwater fishes, but the realized application of Nb has been limited. Using genetic monitoring data for two Arctic grayling (Thymallus arcticus) populations of conservation concern, we describe temporal trends in genetic variation and Nb, determine how sampling and variance in reproductive success influence estimates of Nb, and quantify the relationship among Nb, effective population size (Ne), and adult abundance (Nc). Temporal trends in allelic richness (AR) and Nb tracked known or suspected population trajectories. Nb increased in one population where there has been extensive conservation action, and both Nb and AR tracked a decline in the other population where harsh winter conditions have resulted in overwinter mortality events. After accounting for population demography, Ne estimates for each population were 190.7 and 308.8. Overall, this study demonstrates that temporal genetic data effectively resolve demographic and evolutionary status and trend in Arctic grayling, provides insight into the demographic factors that influence genetic variation, and emphasizes the value of temporal genetic data for conservation and management.

A New Species

A new species of Acanthosaura from Yunnan, China, is described based on morphological and genetic data. The new species can be separated from all other species of the genus by having a different shape of the black eye patch, a different coloration of the postorbital and occipital spines and nuchal crest, and a different color of the gular pouch. Genetically, uncorrected sequence divergences of COI between the new species and investigated congeners ranged from 16.12% to 24.11%. The conservation status of the new species is also discussed.
