An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

open access: yesEcological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension (∆a$$ \Delta a $$) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

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.

Tracking Dehydration Reactions and Fossil Fluid Flux in Shear Zones Using Garnet Microstructures

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Shear zones act as preferential fluid pathways during prograde and retrograde stages of metamorphism. Nonetheless, we still have limited knowledge of the drainage and permeability of natural settings. The preserved signature of fluid in exhumed rocks provides insights into fluid flow during burial and exhumation.

Welfare and Felt Duration

open access: yesNoûs, EarlyView.
ABSTRACT How should we understand the duration of a pleasant or unpleasant sensation, insofar as its duration modulates how good or bad the experience is overall? Given that we seem able to distinguish between subjective and objective duration and that how well or badly someone's life goes is naturally thought of as something to be assessed from her ...
