Global diversity of large branchiopods
(Crustacea: Branchiopoda) in freshwater.
Several studies have trapped airborne propagules of branchiopods
. Brendonck and Riddoch (1999) trapped only a few B.
There are also similarities in respect of branchiopods
between the Mpumalanga pans and turbid clay pans in Australia (Hancock & Timms 2002), ponds in Oxfordshire (UK) (Collinson et al.
Because the brain anatomy of branchiopods
is much simpler than that of malacostracans, they have been regarded as the more likely ancestors of the arthropod lineage that would give rise to insects.
Strausfeld said: "There have been all sorts of implications why branchiopods
shouldn't be the ancestors of insects.
As a group, branchiopods
are united by the presence of gills on their legs and various appendages used for swimming.
In cooperation with natural heritage program members in all 50 states, NatureServe has compiled, and maintains, a detailed database of over 21,000 plant and animal species in the United States, including nearly 16,200 vascular plants, approximately 2,550 native vertebrate animal species (including mammals, birds, reptiles, amphibians, and freshwater fishes), and a wide spectrum of invertebrates (including "all 2,600 species in the following groups: freshwater mussels, freshwater snails, crayfishes, large branchiopods
, butterflies and skippers, underwing moths, tiger beetles, and dragonflies and damselflies").
Their planktonic fish belong to many genera of branchiopods
(of the orders Anostraca, Conchostraca, and Notostraca) and copepods.
While collecting amphibians, particularly in ephemeral and seasonal pools, I commonly encountered representatives of the three orders of branchiopods
(Conchostraca, Notostraca, and Anostraca).
The genus Biapertura was proposed by Smirnov (1971) to contain alonid branchiopods
with two main pores connected on the headshield.
Horne (1967) surveyed branchiopods
throughout Wyoming, and found diverse communities at most sites.
The thousands of large and small pools that form annually are an ideal study area for freshwater branchiopods
capable of surviving drought by forming resting eggs.
