Testing multiple environmental DNA substrates for detection of the cryptic and Critically Endangered burrowing freshwater crayfish Engaewa pseudoreducta

Environmental DNA
Effective conservation of endangered species depends on knowledge of their distributions, but species detection can often be challenging. An example of this is provided by the Critically Endangered Margaret River burrowing crayfish (Engaewa pseudoreducta)

Fibrillisation and Mechanical Properties of Plasma‐Treated Modification LDPE/PA6 Microfibrillar Composites

Journal of Applied Polymer Science, EarlyView.
Plasma treatment enhances interfacial adhesion between LDPE/PA6 via carbonyl group formation. PA6 droplet size heterogeneity reduced to ~850 nm after plasma treatment. Drawing at 160°C produces highly oriented microfibrils with faster throughput. Plasma‐treated MFCs show up to 500% tensile strength increase and 18% higher stiffness.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

A Market-Based Approach to Manage Endangered Species Interactions [PDF]

An economic activity interacts with an endangered species. The activity can be divided into mutually exclusive strata with different levels of interaction. Observing the activity in order to monitor interactions is costly.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

New records of Nototriche hartwegii A.W.Hill (Malvaceae, Malvoideae) in Ecuador: updated distribution and range extension [PDF]

Check List
We report a new record of Nototriche hartwegii A.W.Hill, an Ecuadorian endemic species originally described from the southern Andes. For decades, its known distribution was restricted to this region.
