Rediscovery of a halophytic endemic and rare species of Portulaca (Portulacaceae) from central Argentina: morphology and its phylogenetic position

Portulaca ragonesei (Portulacaceae), an extreme holophyte species from Salina de Ambargasta, central Argentina, is here illustrated and re-described based on morphological evidence. In addition, molecular data shows that this endemic species is one of the earliest-divergent lineages of the Oleracea clade. This is a critically endangered species that can be morphologically distinguished by its sprouting geophytes habit, the linear leaves, and the presence of constriction at the apex of the pixidium where only one seed is found.

We describe here Bertolonia lucernula, a new endemic species from the state of Espírito Santo, Brazil. It is only known from one locality, the “Área de Proteção Ambiental Mestre Álvaro”, in the municipality of Serra. The new species can be recognized by the branches and petioles covered with sessile and short-stalked glands and scattered unbranched trichomes, flat leaf blade surfaces covered only with sessile and short-stalked glands, small flowers with a widely campanulate hypanthium covered with the same trichomes as the petioles, calyx with membranaceous, truncate sepals, and short, triangular external teeth, asymmetric and obovate petals, with the apex covered with sessile and short-stalked glands on the adaxial surface. According to IUCN criteria, Bertolonia lucernula should be classified as Critically Endangered (CR).

Eighty-two species or other forms of rare mammals were kept in 19 zoological gardens of the Czech Republic and Slovakia as of 1 January 2016. Two mammal species extinct in the wild (EW category of the IUCN) were bred in the zoos in 2015. Of the kept 29 critically endangered species (CR), 17 bred successfully in 2015, while of the kept 51 endangered species (EN), 25 did. Nine zoos bred more than one third of their kept species belonging to the three categories. The breeding of rare species of perissodactyls and artiodactyls was the most successful in the respective zoos.

A New Species

Abstract—The karst area in South China is notable for its fragile vegetation and unique flora with many narrow endemic species, and is one of the most threatened biodiversity hotspots in the world. However, the biodiversity of acid soil areas scattered in the karst area have previously been underestimated. With a recent increase of new discoveries of plants and animals, the conservation of biodiversity in these acid soil areas has become urgent. This study deals with a new species, Impatiens longlinensis. The new species is similar to I. yui and I. lasiophyton in having pubescence, two lateral sepals, funnelform lower sepal, and linear capsule. But it can be distinguished by having orbicular to obovate dorsal sepals and oblong to elliptic lower and upper lobes of lateral united petals. Moreover, molecular data and micro-morphological evidence also support that the species is new to science. The new species is only known from a valley near the summit of Mt. Jinzhongshan within an area of less than 5 km2. Based on the Red List categories and criteria developed by the International Union for Conservation of Nature, and the threat posed by exploitation for tourism development, we categorize it as Critically Endangered (CR).

First Time

In 1890, Salvia freyniana Bornm., an endemic species of Turkey, was first collected and described by J.F. Bornmueller in 1892. While revising the genus occurring in Turkey based on specimens collected from Yenipazar, south of Yozgat (Turkey in 1892), it was discovered once again in 2006. The diagnostic morphological characters of this rare endemic species are discussed. Details of fruiting material and pollen micromorphology are given for the first time. Moreover, an emended and expanded description, distribution, phenology and ecology of this species are also provided along with its conservation status.

Centers Of Endemism

Brazilian rupestrian grasslands (campos rupestres) are old, climatically buffered infertile landscapes, which support many endemic species. Asteraceae show the high levels of plant endemism and contain more endangered species than any other family in Brazil. Here, we evaluated the complementarity of two protected areas for the conservation of endangered Asteraceae along the Espinhaço Mountain range, Southeast Brazil. Specifically, we investigated if the known endangered Asteraceae flora of the Diamantina District Plateau (38 species) occurs in two protected areas, Rio Preto State Park and Sempre Vivas National Park, and if these areas are complimentary or overlapping in protecting endangered Asteraceae species. To survey Asteraceae, we used a standardized RAPELD protocol (21 1 ha plots) and traditional floristic collecting (117 ha polygon/32 days/average team = 2.1 collectors) across different habitats and altitudes within both areas. RAPELD protocol recorded 115 species in a sample of 12,775 individuals of Asteraceae. Traditional floristic collecting recorded 172 species in a sample of 613 collections. Seventy-nine percent of endangered species known to occur within the Plateau were recollected by either RAPELD or traditional floristic collecting. Only 13% of endangered Asteraceae flora was common to both protected areas; 47% occur in Rio Preto State Park and 34% in Sempre Vivas National Park; combined, they recorded 68% of the endangered Plateau Asteraceae flora; only one critically endangered species was recorded. The two parks are complimentary but insufficient to protect the endangered Asteraceae flora of the Plateau; the uneven distribution of endangered species in the Diamantina District Plateau is a threat to their conservation.

Anthropogenic Environment

Melanophryniscus admirabilis (admirable red-belly toad) is a microendemic and critically endangered species found exclusively along 700 m of the Forqueta River, in a fragment of the Atlantic Forest of southern Brazil. One of the greatest concerns regarding the conservation of this species is the extensive use of pesticides in areas surrounding their natural habitat. In recent years, the adaptation and persistence of animal species in human-impacted environments have been associated with microbiota. Therefore, the present study aimed to characterize the oral bacterial community of wild M. admirabilis and to address the question of how this community might contribute to this toad’s adaptation in the anthropogenic environment as well as its general metabolic capabilities. A total of 11 oral samples collected from wild M. admirabilis were characterized and analyzed via high-throughput sequencing. Fragments of the 16S rRNA variable region 4 (V4) were amplified, and sequencing was conducted using an Ion Personal Genome Machine (PGM) System with 316 chips. A total of 181,350 sequences were obtained, resulting in 16 phyla, 34 classes, 39 orders, and 77 families. Proteobacteria dominated (53%) the oral microbiota of toads, followed by Firmicutes (18%), Bacteroidetes (17%), and Actinobacteria (5%). No significant differences in microbial community profile from among the samples were reported, which suggests that the low dietary diversity observed in this population may directly influence the bacterial composition. Inferences of microbiome function were performed using PICRUSt2 software. Important pathways (e.g., xenobiotic degradation pathways for pesticides and aromatic phenolic compounds) were detected, which suggests that the bacterial communities may serve important roles in M. admirabilis health and survival in the anthropogenic environment. Overall, our results have important implications for the conservation and management of this microendemic and critically endangered species.
