Seasonal invertebrate communities in multiple use jarrah forests. Implications for conservation and management [PDF]

open access: yes, 2004
The response of ground-dwelling jarrah forest invertebrates to logging (but not a post-harvest burning) was examined in the Kingston, Warrup and Winnejup forest blocks, approximately 25 km north-east of Manjimup in the south-west of Western Australia ...

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation

open access: yesAdvanced Robotics Research, EarlyView.
A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.

Ultrafiltration and Fluid Excretion in Echinoids Involves the Axial Organ with Elimination via the Intestine

open access: yesLife
Many animals display nephridial structures for the ultrafiltration of metabolic waste. However, a nephridial equivalent and an excretory system are not generally recognized for echinoderms.

Life cycle truncation in Digenea, a case study of Neophasis spp. (Acanthocolpidae)

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2021
Truncated life cycles may emerge in digeneans if the second intermediate host is eliminated, and the first intermediate host, the mollusc, takes up its role.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

open access: yesAdvanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
