Sexual conflict as a constraint on asexual reproduction: an empirical review

open access: yesBiological Reviews, EarlyView.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Native insect species should be selected for classroom rearings

open access: yesInsect Conservation and Diversity, EarlyView.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Comparative Analysis of Mechanical Properties of Arolium and Euplantulae in Medauroidea extradentata (Phasmatodea), Using In Vivo Atomic Force Microscopy, Supports Functional Specialization of both Types of Attachment Pads

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 19, October 6, 2025.
Stick insects use two different types of smooth attachment pads for locomotion, the pretarsal arolium for adhesion and tarsal euplantulae for friction. With atomic force microscopy (AFM) measurements on these pads on living and conscious insects, this work demonstrates that each pad exhibits distinct material properties aligned with its function.
