Parallel molecular routes to cold adaptation in eight genera of New Zealand stick insects. [PDF]

open access: yes, 2015
The acquisition of physiological strategies to tolerate novel thermal conditions allows organisms to exploit new environments. As a result, thermal tolerance is a key determinant of the global distribution of biodiversity, yet the constraints on its ...

A Multithreat Meta‐Analytic Database for Understanding Insect Biodiversity Change

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Widespread declines in insect biodiversity have been attributed to a diverse set of anthropogenic drivers, but the relative importance of these drivers remains unclear. A key reason for this uncertainty is that their effects depend on many factors, such as taxonomy, geography, sampling method and the biodiversity metric considered.

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

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.

New records of exotic spiders and insects to the Azores, and new data on recently introduced species [PDF]

open access: yes, 2013
The introduction of exotic species in islands is recognized as a major threat to native biota and ecosystems. In this contribution we list thirteen widespread exotic invertebrate species (two Araneae, one Orthoptera, four Hemiptera, four Coleoptera and ...

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.
