The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation

open access: yesBiological Reviews, Volume 100, Issue 2, Page 647-671, April 2025.
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close

Endogenous cellulase enzymes in the stick insect (Phasmatodea) gut

open access: yesJournal of Insect Physiology, 2014
High cellulase (endo-beta-1,4-glucanase) activity was detected in the anterior midgut of the walking stick (Phasmatodea) Eurycantha calcarata. The enzyme was isolated and analyzed via mass spectrometry. RT-PCR revealed two endoglucanase genes, EcEG1 and EcEG2.

Barcode 100K Specimens: In a Single Nanopore Run

open access: yesMolecular Ecology Resources, Volume 25, Issue 1, January 2025.
ABSTRACT It is a global priority to better manage the biosphere, but action must be informed by comprehensive data on the abundance and distribution of species. The acquisition of such information is currently constrained by high costs. DNA barcoding can speed the registration of unknown animal species, the most diverse kingdom of eukaryotes, as the ...

Performance of DNA metabarcoding, standard barcoding and morphological approaches in the identification of insect biodiversity

open access: yesMolecular Ecology Resources, Volume 24, Issue 8, November 2024.
Abstract For two decades, DNA barcoding and, more recently, DNA metabarcoding have been used for molecular species identification and estimating biodiversity. Despite their growing use, few studies have systematically evaluated these methods.

Immunocytochemical localization of tubulins in spermatids and spermatozoa of Euptoieta hegesia (Lepidoptera : Nymphalidae) [PDF]

open access: yes, 2005
A comparative analysis of the distribution of tubulin types in apyrene and eupyrene sperm of Euptoieta hegesia butterflies was carried out, also verifying the presence of tubulin in lacinate appendages of the eupyrene sperm.

Multi‐method approach to assessing the floral‐visiting insect assemblage of rare, ambophilous plant Baccharis vanessae in Southern California

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
In this study, we compare the accuracy of two different methods of monitoring to assess the insect assemblage of Encinitas Baccharis (Baccharis vanessae): focal observations and video recordings from camera traps. The insect vectors identified were as expected given B. vanessae pollination syndrome.

Sexual dimorphism dominates divergent host plant use in stick insect trophic morphology [PDF]

open access: yes, 2013
Background: Clear examples of ecological speciation exist, often involving divergence in trophic morphology. However, substantial variation also exists in how far the ecological speciation process proceeds, potentially linked to the number of ecological ...
