The structure of extremely long mouthparts in the aphid genus Stomaphis Walker (Hemiptera: Sternorrhyncha: Aphididae) [PDF]

open access: yes, 2015
Scanning electron microscopy and light microscopy were used to elucidate the morphology of labium and mandibular and maxillary stylets of the aphids Stomaphis quercus (L.) and S. graffii Cholodkovsky.

The Detri2match conceptual framework: Matching detritivore and detritus traits to unravel consumption rules in a context of decomposition

open access: yesFunctional Ecology, Volume 38, Issue 10, Page 2084-2098, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract From soil to freshwater ecosystems, decomposition can be conceived as the result of interactions between organic matter and a diversity of organisms. This function is driven in part by detritivores, invertebrates that feed on detritus or graze on its associated microbes

Ökomorphologie : Integration von Form, Funktion und Ökologie bei der Analyse morphologischer Strukturen [PDF]

open access: yes, 2008
Organisms are complex entities whose study has necessitated an increasingly reductionistic stance in modern biology (CAPLAN 1987). As a consequence, biology as a science has been split up into numerous sub-disciplines.

Plant Silicon Defences Suppress Herbivore Performance, but Mode of Feeding Is Key

open access: yesEcology Letters, Volume 27, Issue 10, October 2024.
The performance of herbivores is influenced by the nutritional and defensive traits of plants, with biogenic silicon being a common anti‐herbivore defence, especially in grasses. Our meta‐analyses of 150 studies revealed that higher silicon levels in plants led to a 33% decline in overall herbivore performance, with chewing herbivores being more ...

The evolutionary history of Coleoptera (Insecta) in the late Palaeozoic and the Mesozoic

open access: yesSystematic Entomology, Volume 49, Issue 3, Page 355-388, July 2024.
Structural transformations of the elytra and abdomen played a major role in the early beetle evolution in the Permian. Polyphaga appear late in the fossil record, with only a few fossils of Elateriformia in the Late Triassic. Several factors were involved in the enormous diversification of beetles in the Cretaceous but evolutionary interactions with ...

Localization of Lupoid Leishmaniasis on the face: A case control study

open access: yesJEADV Clinical Practice, Volume 3, Issue 2, Page 653-657, June 2024.
Abstract Background In Lupoid Leishmaniasis, erythematous to brown papules often occur around a central old scar, which can expand over time. For unclear reasons, these lesions tend to develop on the facial area. Objectives This study was conducted to study the distribution of Lupoid Leishmaniasis lesions on the face and compare them with those of ...

The “elongate chelicera problem”: A virtual approach in an extinct pterygotid sea scorpion from a 3D kinematic point of view

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
How pterygotid sea scorpions used their tripartite elongate cheliceres to get prey items close to the mouth region remains a conundrum. We applied four different 3D kinematic settings with regard to insertion and orientation of the cheliceres to examine the most likely way this was realized.

Morphology and evolution of Malacostraca [PDF]

open access: yes, 2014
In this dissertation project comparative morphological studies on the nervous system, mandible structure and sensory equipment of Decapoda and Peracarida are presented and interpreted with regard to the evolution of the taxa.

The appendage role of insect disco genes and possible implications on the evolution of the maggot larval form [PDF]

open access: yes, 2007
Though initially identified as necessary for neural migration, Disconnected and its partially redundant paralog, Disco-related, are required for proper head segment identity during Drosophila embryogenesis.

Homologs of Drosophila Appendage Genes in the Patterning of Arthropod Limbs [PDF]

open access: yes, 2000
Studies of the genes involved in patterning the appendages of Drosophila melanogaster have revealed a system of signaling and transcriptional regulation that is responsible for specifying the proximo-distal limb axis.
