Streptocephalus sirindhornae, new species of freshwater fairy shrimp (Anostraca) from Thailand [PDF]

Journal of Crustacean Biology, 2000
Streptocephalus sirindhornae, new species, the first freshwater anostracan from Thailand, is wide-spread in the northeast of the country. It is morphologically closest to the Indian species S.

Detection and succession properties of forested vernal pools with eDNA metabarcoding

Ecological Solutions and Evidence
Vernal pools are small seasonal wetlands found throughout North America, where they provide critical habitat for a variety of organisms, including many cryptic taxa of conservation concern.

The reach of road salt into vernal pools and the response of amphibians. [PDF]

PLoS ONE
Deicing salts are causing freshwater wetlands to become increasingly saline near roadways, with cascading impacts on local ecosystems. Understanding the full reach of salt into surrounding landscapes can inform the decisions made every winter about ...

New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)

Zoodiversity, 2021
We report and describe new Chirocephalus diaphanus gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance.

LC-DAD-MSⁿ and HR-LC-QTOF Analysis of Ziziphus budhensis Leaves and Evaluation of Their In Vitro and In Vivo Biological Activities. [PDF]

Chem Biodivers
ABSTRACT Ziziphus budhensis Bhattarai & M.L. Pathak is a specie described in 2015 in Nepal poorly studied for its phytochemical composition and possible bioactivities. In this study, six extracts were obtained from Z. budhensis leaves using ultrasound assisted extraction with solvents in increasing polarity namely hexane, dichloromethane, chloroform ...

Maternal investment influences expression of resource polymorphism in amphibians: implications for the evolution of novel resource-use phenotypes. [PDF]

PLoS ONE, 2010
Maternal effects--where an individual's phenotype is influenced by the phenotype or environment of its mother--are taxonomically and ecologically widespread. Yet, their role in the origin of novel, complex traits remains unclear.

Keystone Predation: What Is It, and Is It Supported by Empirical Evidence? [PDF]

Ecol Evol
Keystone predation has been widely cited as a key ecological mechanism controlling community structures, but is supported by limited theoretical and experimental studies. Reviewing these studies showed keystone predation has been documented across realms, appears to be most prevalent in sessile and dispersal‐limited communities and can be modified by ...

Large branchiopods in extensive carp ponds – morphometric analysis of Triops cancriformis (Bosc, 1801) and Streptocephalus torvicornis (Waga, 1842)

Oceanological and Hydrobiological Studies, 2023
Large branchiopods is a group of poorly understood crustaceans which is highly threatened by the impact of human activities. Currently, their protection is difficult due to large deficiencies in documentation of their places of occurrence and not well ...

Current knowledge of the South East Asian large branchiopod Crustacea (Anostraca, Notostraca, Laevicaudata, Spinicaudata, Cyclestherida)

Journal of Limnology, 2013
The large branchiopod crustaceans (fairy shrimp, tadpole shrimp and clam shrimp) of South East (SE) Asia have only recently been examined with scientific vigor. Although more than 70 species have been reported for Asia and Indonesia, only six native taxa

Branchinecta gaini Daday, 1910 (Branchiopoda, Anostraca) as a bioindicator of oligotrophic and low conductivity shallow ponds in southern Chilean Patagonia [PDF]

, 2012
The south of Patagonia is characterized by its semi-arid weather and numerous small, temporary and permanent shallow ponds. The aquatic crustaceans of these water bodies are characterized by their endemism and species richness. The present study was done
