Impacts of mining activities on the potential geographic distribution of eastern Brazil mountaintop endemic species

Many Brazilian Atlantic Rainforest plant and animal species are geographically restricted to Southern Bahia and Northern Espírito Santo States. We investigated the geographic distribution of epiphytic bromeliads in the lowland forest of the Una region (15° 17' 34' S - 39° 04' 30'' W) in Southern Bahia. Specifically, we addressed the following questions: i) what is the extent of each species distribution?; and ii) are the Bromeliaceae subfamilies distributed differently from one another? Almost half of the 40 species (47.5%) occur exclusively in the Southern Bahia-Northern Espírito Santo region and are herein referred as endemic species. The highest percentage of the 15 species of Tillandsioideae (46.7%) occur throughout the South American Continent and most of the 25 species of Bromelioideae (68.0%) are mainly represented by endemic species. The Una region has almost two times more species than a forested area located 40 km west, suggesting marked increases in diversity in over relatively short distances. The endemism data around Una indicates that species are geographically distributed over an area spanning approximately six to seven degrees in latitude and longitude. This result contrasts with the geographic distribution of Andean epiphytes, mainly represented by Tillandsioideae, that have large geographical distributions. Larger-scale analyses and standardized methods are necessary to verify whether the narrow geographical distribution of most epiphytic bromeliads in the Una region is consistent across different forest types of the Atlantic Rainforest.

Potential Geographic Distribution

In Colombia, little is known on the distribution of the Asian mosquito Aedes albopictus, main vector of dengue, chikungunya, and Zika in Asia and Oceania. Therefore, this work sought to estimate its current and future potential geographic distribution under the Representative Concentration Paths (RCP) 2.6 and 8.5 emission scenarios by 2050 and 2070, using ecological niche models. For this, predictions were made in MaxEnt, employing occurrences of A. albopictus from their native area and South America and bioclimatic variables of these places. We found that, from their invasion of Colombia to the most recent years, A. albopictus is present in 47% of the country, in peri-urban (20%), rural (23%), and urban (57%) areas between 0 and 1800 m, with Antioquia and Valle del Cauca being the departments with most of the records. Our ecological niche modelling for the currently suggests that A. albopictus is distributed in 96% of the Colombian continental surface up to 3000 m (p < 0.001) putting at risk at least 48 million of people that could be infected by the arboviruses that this species transmits. Additionally, by 2050 and 2070, under RCP 2.6 scenario, its distribution could cover to nearly 90% of continental extension up to 3100 m (≈55 million of people at risk), while under RCP 8.5 scenario, it could decrease below 60% of continental extension, but expand upward to 3200 m (< 38 million of people at risk). These results suggest that, currently in Colombia, A. albopictus is found throughout the country and climate change could diminish eventually its area of distribution, but increase its altitudinal range. In Colombia, surveillance and vector control programs must focus their attention on this vector to avoid complications in the national public health setting.

Balkan Peninsula

The genus Cernosvitovia consists of nine species in the whole world. Out of the nine species, eight species are with primary distribution in the eastern part of the Balkan Peninsula (except Cernosvitovia schweigeri). In the Lumbricidae fauna of Serbia, seven species from this genus have been registered. Among them, 6 taxa are endemic. The aim of this paper is to present new data of the endemic species Cernosvitovia dudichi Zicsi & Šapkarev, 1982, based on the current taxonomic status of species, literature data, and our unpublished data. In this paper, we have summarized the knowledge on the geographic distribution, biology, and habitat C. dudichi in Serbia. Our recent investigations have revealed new records for C. dudichi in Central Serbia. After 30 years, this species was found in another place in this area, in Goč Mt. New locality suggests that C. dudichi possess a wider range than it was previously thought.

Prolonged Diapause

Brahmaea (Acanthobrahmaea) europaea Hartig, 1963, is an Italian endemic species exhibiting a very restricted geographic distribution (Basilicata and Campania regions, Grotticelle di Monticchio Nature Reserve and neighbouring areas), and developing as larvae on a few Oleaceae (Fraxinus angustifolia subsp. oxycarpa, Ligustrum vulgare and Phyllirea latifolia). From spring 2015 to spring 2017 a series of bioethological observations on the moth were conducted, as well as surveys aimed to study the distribution of its host plants in the habitats of SAC “Grotticelle di Monticchio”. In this short communication a prolonged diapause of B. europaea chrysalis kept in the laboratory is documented. In spring 2018, four successfully adult eclosions occurred from two years old pupae, a case never previously reported in literature records for this rare and threatened taxon.

AbstractThe present study evaluated the size and germination characteristics of seeds of seven species ofSyngonanthus(distributed among four sections) that occur in different microhabitats incampos rupestresvegetation in Minas Gerais State, to determine if (1) the germination responses of the various species characterize a single germination pattern for the genus; and (2) there is a correlation between the germination characteristics and the geographic distribution as well as the microhabitat of the different species. The experiments were undertaken with recently collected seeds exposed to a 12-h photoperiod and continuous darkness, at constant temperatures of 10–40°C (at intervals of 5°C) in germination chambers. The results indicated the existence of a pattern of reduced seed size and light requirements for germination within the genus. The geographic distribution of different species of the genus cannot be explained by the responses of seed germination to different temperatures, but suggests some relationship to their edaphic microhabitats. Therefore, germination characteristics of the populations studied may have been selected to colonize specific environments at different soil water conditions.

Degree Of Overlap

Croton section Cleodora is a Neotropical section disjunctly distributed in Mexico and Central America, northern and northwestern South America, and eastern Brazil. Eighteen species are recognized as belonging to the section, which is characterized mainly by an arborescent or shrubby habit, presence of clear or reddish latex, leaves with a pair of basilaminar or acropetiolar glands, pistillate flowers sepals with some degree of overlap, and 4-fid or multifid styles united at the base or above, usually forming a crown. We conduct a critical revision of Croton section Cleodora, congruent with the current understanding of its evolutionary history. We provide here an identification key for the two recognized subsections (Croton subsection Sphaerogyni and C. subsection Spruceani) and their species. Descriptions, illustrations, comments about taxonomy, habitat, geographic distribution and phenological information are provided for each species. Six lectotypes are here designated.
