A new afrograptid (Diplostraca: Estheriellina) from the Lower Cretaceous of southern England

open access: yesCretaceous Research, 2017
The Family Afrograptidae is a ‘conchostracan’ group with multiple radial costae reaching to the umbo on their carapaces. It comprises four described genera: Afrograpta, Camerunograpta, Congestheriella and Graptoestheriella with a total of thirteen described species which are occasionally reported from the Jurassic and the Cretaceous in Africa, Europe ...

The Acute Toxicity of Salinity in Onshore Unconventional Gas Waters to Freshwater Invertebrates in Receiving Environments: A Systematic Review. [PDF]

open access: yesEnviron Toxicol Chem, 2022
Comparing the acute toxicity (48–96‐h) of sodium chloride (NaCl) and/or synthetic marine salt laboratory exposures of freshwater invertebrates to the salinity in unconventional gas produced waters from coal bed methane and shale gas extraction, and how other major ions (Ca2+, K+, Mg2+, CO32–, HCO3–, SO42–) can influence the toxicity of Na+ and Cl– ions

POST-LARVAL DEVELOPMENTAL DYNAMICS OF THE SPINICAUDATAN (BRANCHIOPODA: DIPLOSTRACA) CARAPACE [PDF]

open access: yesJournal of Crustacean Biology, 2014
The evolution of reproductive systems is of critical importance to evolution and yet has been difficult to examine using paleontological information. Recent studies on freshwater “clam shrimp” in both extant and fossil populations have demonstrated that sex can be inferred by quantifying morphological differences of the carapaces.

Onychocaudata (Branchiopoda: Diplostraca), a new high-level taxon in branchiopod systematics [PDF]

open access: yesJournal of Crustacean Biology, 2013
The systematics of Branchiopoda has received much attention in recent years, and a full understanding of the higher-level classification seems close. Based on a number of phylogenetic analyses involving both morphological and molecular data, some higher-level taxon names have been resurrected in the last decades (Phyllopoda, Diplostraca, Cladocera ...

A phylogenetic analysis of the Conchostraca and Cladocera (Crustacea, Branchiopoda, Diplostraca) [PDF]

open access: yesZoological Journal of the Linnean Society, 1998
A computer-assisted cladistic analysis on morphological characters of the Diplostraca (Conchostraca and Cladocera) has been undertaken for the first time. The morphological information has been obtained from literature and transformed into 56 suitable characters.

Revision of Two Spinicaudatan Species from the Cañadón Asfalto Formation (Jurassic), Patagonia Argentina. [PDF]

open access: yesZool Stud, 2020
Re-examination under a scanning electron microscope (SEM) of the type material of the species described by Tasch and Volkheimer (1970) and Vallati (1986) was applied, as well as, new materials collected from different localities of the Las Chacritas ...

Toxicity studies of Bacillus thuringiensis on non-target organism Daphnia sp. (Diplostraca: Daphniidae) [PDF]

open access: yesAIP Conference Proceedings, 2018
Dengue hemorrhagic fever is caused by dengue viruses that infect female mosquitoes, mainly of the species Aedes aegypti and to a lesser extent Aedes albopictus. One example of a bioinsecticide is Bacillus thuringiensis israelensis (Bti), which is a naturally occurring soil bacterium that can effectively kill mosquito larvae present in water.

Incorporation of colonization pressure into the propagule pressure‐based global ballast water standard

open access: yesDiversity and Distributions, Volume 29, Issue 11, Page 1420-1431, November 2023., 2023
Abstract Aim In 2024, cargo vessels must meet the International Maritime Organization's global ballast water discharge standards (IMO D‐2) that limit the concentration of living organisms. D‐2 focuses on reducing invasion risk by reducing ‘community propagule pressure (CPP)’, though it does not consider colonization pressure (CP).
