Urban peatlands can harbour diverse insect communities but depend on appropriate habitat management

open access: yesInsect Conservation and Diversity, EarlyView.
Urban peatlands can support high insect diversity, including endangered species and peat bog specialists. Flower diversity boosts endangered species, while succession cover reduces overall insect richness—but bog condition and urbanization showed no major effects.

The influence of forest regrowth, original canopy cover and tree size on saproxylic beetles associated with old oaks [PDF]

open access: yes, 2000
Abandoned management has caused many sites with free-standing, large oaks (Quercus robur) to become more shaded. This study shows how forest regrowth affects beetle species associated with old oaks in south-eastern Sweden. Beetles were trapped by pitfall

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

open access: yesInsect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Industrial Hemp Fiber Planting Date Trial [PDF]

open access: yes, 2017
Hemp is a non-psychoactive variety of cannabis sativa L. The crop is one of historical importance in the U.S. and reemerging in worldwide importance as manufacturers seek hemp as a renewable and sustainable resource for a wide variety of consumer and ...

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

Paleoenvironmental analysis of the Mangere Formation, Mangere Island, Chatham Islands, New Zealand : a thesis submitted in Earth Science for the degree of Master of Science at Massey University [PDF]

open access: yes, 2006
Mangere Island consists almost entirely of alkali basalt of the late Miocene early Pliocene Rangiauria Formation (Campbell et al., 1993) with outcrops of the sedimentary Tupuangi Formation on the east coast and the Mangere Formation (Campbell, et al ...
