DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi
(De Gruyter Open Ltd, 2021)
Three new non-geniculate coralline algal species from South Africa are described that were passing under the misapplied name, Spongites yendoi. Based on plastid encoded DNA sequences from psbA and rbcL markers, these species ...
Role of jellyfish in the plankton ecosystem revealed using a global ocean biogeochemical model
(Copernicus GmbH, 2021)
Jellyfish are increasingly recognised as important components of the marine ecosystem, yet their specific role is poorly defined compared to that of other zooplankton groups. This paper presents the first global ocean ...
Records of ctenophores from South Africa
(PeerJ, 2021)
Although ctenophores can be conspicuous components of the plankton in coastal marine ecosystems, only six species have been formally described from around South Africa. Using photographs from local community scientists, ...
Leopards and mesopredators as indicators of mammalian species richness across diverse landscapes of South Africa
(Elsevier, 2021)
The rapid extinction of species over the past few decades has created a biodiversity crisis. Factors contributing to recent extirpations are linked to increased human population growth, habitat loss and fragmentation, and ...
Codon-based analysis of selection pressure and genetic structure in the Psammobates tentorius (Bell, 1828) species complex, and phylogeny inferred from both codons and amino acid sequences
(John Wiley & Sons, 2021)
This study used codon analysis (dN/dS and Tv/Ti) to investigate selection pressure
and genetic structure in the highly polymorphic Psammobates tentorius species
complex, and amino acid sequences to construct a phylogeny ...
Opportunities for improving recognition of coastal wetlands in global ecosystem assessment frameworks
(Elsevier, 2021)
Vegetated coastal wetlands, including seagrass, saltmarsh and mangroves, are threatened globally, yet the need to avert these losses is poorly recognized in international policy, such as in the Convention on Biological ...
A new macromedusa from the coast of Mozambique: Aurelia mozambica sp. nov. (Scyphozoa: Ulmaridae)
(Magnolia Press, 2021)
A new species of the cosmopolitan jellyfish genus Aurelia is described from the coastal waters of Mozambique using a combination of morphological, meristic and genetic information (COI and 18S). The species can be separated ...
Genome sequence of an alkaliphilus species isolated from historically contaminated sediments of the gulf of Naples (Mediterranean Sea)
(American Society for Microbiology, 2021)
Here, we report the draft genome sequence of a metagenome-assembled genome (MAG) of a new Alkaliphilus bacterium, NP8, of the Clostridiaceae family. This bacterium was isolated from polluted sediment collected from an ...
How much leaf area do insects eat? A data set of insect herbivory sampled globally with a standardized protocol
(Ecological Society of America, 2021)
Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area is removed ...
Variation and change of upwelling dynamics detected in the world's eastern boundary upwelling systems
(Frontiers Media, 2021)
Global increases in temperature are altering land-sea temperature gradients. Bakun (1990) hypothesized that changes within these gradients will directly affect atmospheric pressure cells associated with the development of ...
