It has been documented that some species of terrestrial isopods in the genera Porcellio and Armadillidium engage turn alternation (TA) to maintain a straight path while exploring new terrains, escaping inhospitable conditions, or avoiding predators. Within Porcellio, such studies are most often conducted with scaber (Latreille, 1804) laevis 1804), leaving extent TA other unexplored. Consequently, behavior is assumed isopods, despite lack documentation. Therefore, current study investigated spinicornis (Say, 1818) Trachelipus rathkii (Brandt, 1833) using commonly employed multiple T-maze. Both P. T. were found at frequencies significantly above random chance. The data also showed marginal interaction between group sex, females, but not males, TA. provides first documentation extends this genus - broadening our understanding across isopod taxa. Furthermore, suggests may follow pattern sex-specific selection could differ among isopods. Further on broader range reveal important ecological evolutionary patterns.

Abstract Soil organic matter (SOM) transformation processes are regulated by the activities of plants, microbes, and fauna. Compared with plants effects soil fauna less understood because their high taxonomic functional diversity, mix direct indirect effect mechanisms. Trait‐based approaches offer a generic perspective to quantify mechanistic relationships between SOM transformations, including decomposition, translocation, stabilisation carbon. Yet, at present, we lack consensus concerning relevant key traits (i.e. those affecting ecosystem functioning). Here, address this knowledge gap focusing on transformations. Based existing literature, identify linked universally applicable across taxa types, discuss process‐trait links. We define eight that directly affected fauna: (i) litter mass loss, (ii) fragmentation, (iii) aggregation in faeces, (iv) mineral particles, (v) decomposition (vi) (vii) pore space creation maintenance (viii) stabilisation. link these general classified into four categories: (a) food selection ingestion, (b), digestion excretion, (c) mobility, (d) body metabolic rate. also propose proxies when trait measurements laborious. The proposed links need be validated targeted experiments. urge researchers obtain quantitative experimental data, together approaches, integratively contributions functioning.

Abstract From soil to freshwater ecosystems, decomposition can be conceived as the result of interactions between organic matter and a diversity organisms. This function is driven in part by detritivores, invertebrates that feed on detritus or graze its associated microbes have significant but extremely variable contribution decomposition. In order better understand predict detritivore–detritus pairwise interactions, we propose conceptual framework, called Detri 2 match, study consumption detri tus tivores, using trait‐ match ing approach at individual detritivore level. Here, focus interaction saprophagous detritivores fragment plant detritus. We novel definition an animal consumes when traits sufficiently resource, passing through five facets consumption. These include (1) spatial rule regarding encounter, (2) biomechanical ingestion, (3) digestive assimilation, (4) energetic fulfilment metabolic needs (5) nutritional chemical element adapted proportions. The main goal this framework guide future research establish generic rules misunderstood detritus–detritivore identifying relevant their key for both investigation should conducted over temporal variability trait‐matching constraints throughout whole process. Coupled with adequate accumulation trait information, could also facilitate predictions inference non‐tested detritivore–litter interactions. outline conceptual, methodological analytical challenges framework. challenge would scale up these detrital network level test genericity, which contribute understanding functioning Read free Plain Language Summary article Journal blog.
