    A conservation palaeobiological approach to assess faunal response of threatened biota under natural and anthropogenic environmental change (2019)
    In:  Various articles (1726-4189) vol.16 (2019) p.2423

    Description: Palaeoecological records are required to test ecological hypotheses necessary for conservation strategies asshort-term observations can insufficiently capture natural variability and identify drivers of biotic change. Here, we demonstrate the importance of an integrated conservationpalaeobiology approach when making validated decisions for conservation and mitigating action. Our model system isthe Razim–Sinoie lake complex (RSL) in the Danube Delta (Black Sea coast, Romania), a dynamic coastal lake system hosting unique Pontocaspian mollusc species that are now severely under threat. The Pontocaspians refer to an endemic species group that evolved in the Black Sea and Caspian Sea basins under reduced salinity settings over the past few million years. The natural, pre-industrial RSL contained a salinity gradient from fresh to mesohaline (18 ppm) until human intervention reduced the inflow of mesohaline Black Sea water into the lake system. We reconstruct the evolution of the RSL over the past 2000 years from integrated sedimentary facies and faunal analyses based on 11 age-dated sediment cores and investigate the response ofmollusc species and communities to those past environmental changes. Three species associations (“marine”, “Ponto-caspian” and “freshwater”) exist and their spatio-temporal shifts through the system are documented. Variable salinity gradients developed, with marine settings (and faunas) dominating in the southern part of the system and freshwater conditions (and faunas) in the northern and western parts. Pontocaspian species have mostly occurred in the centre of the RSL within the marine–freshwater salinity gradient. Today, freshwater species dominate the entire system, and only a single Pontocaspian species (Monodacna colorata) is found alive. We show that the human-induced reduced marine ininfluence in the system has been a major driver of the decline of the endemic Pontocaspian biota. It urges improved conservation action by re-establishing a salinity gradient in the lake system to preserve these unique species.

    Notes on Justicia sect. Monechma (Acanthaceae) in Angola, including two new species (2019)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (2212-1676) vol.64 (2019) p.97

    Description: Two new species of Justicia sect. Monechma, Justicia cubangensis and J. eriniae, are described from Angola. Their affinities are reviewed, together with a discussion on the correct generic name to apply to these species. A conspectus of Justicia sect. Monechma ‘Group I’ in Angola is presented, including a key to the species and notes on habitat and distribution for each taxon. Two new combinations and one new name are provided for species for which there was no previous name available in Justicia, and lectotypes are proposed for four names. Twelve species are recognised in this group in total, eight of which are currently believed to be endemic to Angola. Justicia subsessilis is recorded in Angola for the first time, and J. laeta is placed in sect. Monechma, having previously been tentatively referred to sect. Tyloglossa. Monechma carrissoi is considered to be conspecific with J. virgultorum and so is synonymised here. In addition, the botanical importance of the type locality of J. cubangensis, the Cuchi River gorge of the Cubango drainage, is highlighted and two further new provincial records for Cuando Cubango are noted from this site: Eriocaulon angustibracteum (Eriocaulaceae) and Crepidorhopalon schweinfurthii (Linderniaceae).

    Description: A comprehensive morphological and genetic study of type material and new collections of sequestrate Russulales species formerly belonging to the genera Arcangeliella, Elasmomyces, Gymnomyces, Hydnangium, Hymenogaster, Macowanites, Martellia, Secotium and Zelleromyces is here undertaken, for the purpose of providing a complete taxonomical revision of sequestrate Russulaceae species in the Mediterranean and temperate regions of Europe. As a result, seven distinct taxa in the genus Lactarius and 18 in the genus Russula are identified. Six of them are new species: L. populicola, L. subgiennensis, R. bavarica, R. candidissima, R. hobartiae and R. mediterraneensis, and seven represent new combinations: L. josserandii (≡ Zelleromyces josserandii), L. soehneri (≡ Hydnangium soehneri), R. candida (≡ Hydnangium candidum), R. cerea (≡ Hydnangium cereum), R. messapica var. messapicoides (≡ Macowanites messapicoides), R. meridionalis (≡ Zelleromyces meridionalis) and R. neuhoffii (≡ Hydnangium neuhoffii). Twenty-two of the 25 taxa are illustrated, while descriptions, microscopy images, as well as extensive information on the ecology, chorology and phylogeny for all taxa are provided. A key is further included to facilitate their identification.

    Mollusc species from the Pontocaspian region – an expert opinion list (2019)

    Description: Defining and recording the loss of species diversity is a daunting task, especially if identities of species under threat are not fully resolved. An example is the Pontocaspian biota. The mostly endemic invertebrate faunas that evolved in the Black Sea – Caspian Sea – Aral Sea region and live under variable salinity conditions are undergoing strong change, yet within several groups species boundaries are not well established. Collection efforts in the past decade have failed to produce living material of various species groups whose taxonomic status is unclear. This lack of data precludes an integrated taxonomic assessment to clarify species identities and estimate species richness of Pontocaspian biota combining morphological, ecological, genetic, and distribution data. In this paper, we present an expert-working list of Pontocaspian and invasive mollusc species associated to Pontocaspian habitats. This list is based on published and unpublished data on morphology, ecology, anatomy, and molecular biology. It allows us to (1) document Pontocaspian mollusc species, (2) make species richness estimates, and (3) identify and discuss taxonomic uncertainties. The endemic Pontocaspian mollusc species richness is estimated between 55 and 99 species, but there are several groups that may harbour cryptic species. Even though the conservation status of most of the species is not assessed or data deficient, our observations point to deterioration for many of the Pontocaspian species.

    Taxonomy and evolutionary history of the neotropical fern genus Salpichlaena (Blechnaceae) (2019)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (2212-1676) vol.64 (2019) p.1

    Publication Date: 2019-03-04
    Description: Salpichlaena is a distinctive fern genus characterised by 2-pinnate climbing fronds with indeterminate growth. The number of species in the genus has been a matter of debate. Taxonomic studies are made difficult by within-frond variability in pinna morphology and size, and by herbarium material being incomplete. We systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena and 11 outgroup specimens. DNA sequences included plastid genes (rbcL, rpoC1 and rps4), intergenic spacers (rps4-trnS, trnHpsbA and trnG-trnR) and a nuclear gene (pgiC). Phylogenetic analyses based on the plastid markers divided the samples into six major clades. We recognise the three deepest clades as distinct species (S. hookeriana, S. papyrus sp. nov. and S. volubilis), and each of the four shallower clades as a subspecies of S. volubilis. Furthermore, we suggest that a group of specimens, placed into different clades in the plastid and nuclear trees and showing mixed morphological characters, represent a fourth species of hybrid origin (S. hybrida sp. nov.). The most important diagnostic characters are: degree of lamina reduction in fertile pinnules; pinna/pinnule apex incisions, pinna/pinnule margin thickness and lamina texture in sterile pinna/pinnules; presence or absence of foliar buds; shape of scales; and the appearance of the abaxial surface of the lamina (uniform or with stomata on small white protuberances). Each of the four species can be identified by several diagnostic characters, and their geographical ranges are broad and partly overlapping. In contrast, the subspecies are mostly allopatric and their morphological limits are diffuse.
