Three interesting Cyprididae (Ostracoda) from Western Australia [PDF]
The paper contributes to the systematics of the family Cyprididae and to a description of the general ostracod biodiversity in Australia. Riocypris hinzeae sp. nov., is described from wells in the Murchison region (Western Australia).

Pelvic spine reduction affects diet but not gill raker morphology in two polymorphic brook stickleback (Culaea inconstans) populations. [PDF]
The extent of parallelism might generally be lower in between‐species versus between‐population comparisons. In two populations of brook sticklebacks, we found that diet differences were associated with pelvic spine reduction, but we found no evidence of any difference in gill raker morphology associated with pelvic spine reduction. This is in contrast

Diversity and composition of macroinvertebrate communities in a rare inland salt marsh. [PDF]
Inland salt marshes are rare habitats in the Great Lakes region of North America, formed on salt deposits from the Silurian period. We used morphological and COI metabarcoding data to assess changes in diversity and composition across both space (a transect from the salt seep to an adjacent freshwater area) and time (three sampling seasons).

A bothremydid turtle (Pleurodira) from the middle Cenomanian of Vale de Figueira (Belas, Portugal). [PDF]
Abstract An unpublished turtle shell from the middle Cenomanian of Vale de Figueira, near Belas (Lisbon District, Portugal), is recognized by us as collected in 1880 under the direction of Carlos Ribeiro. No turtle remains from that region had so far been figured, described or discussed from a systematic point of view.

Abstract Many aquatic invertebrates that inhabit temporary ponds produce resting forms to overcome the dry period, building up the egg bank. When the wet phase returns, the resting forms hatch and the community is restored, and then pioneer species may have a major influence on how the pond community will assemble. We aimed to evaluate the diversity of

Abstract We present a palaeohydrological reconstruction of Lake Texcoco over the last 32.7 cal ka based on ostracod records consisting of two species, Candona patzcuaro and Limnocytherina axalapasco. Overall, the presence of these species suggests that Lake Texcoco was highly saline and experienced occasional desiccation periods.

Development of a flow‐sensitive macroinvertebrate index for Australian rivers
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.
