Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees
Ecological Entomology, EarlyView.We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Ecological Entomology, EarlyView.Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Ecological Entomology, EarlyView.Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

, 2010 Grasshoppers may at times become serious pests on ornamentals, vegetable and field crops. Grasses and other herbaceous plants are the most common food for these pests, but after those hosts are consumed the grasshoppers often turn to feeding on ...

Trans‐oceanic migration and wind utilization by Amur Falcons (Falco amurensis)
Ibis, EarlyView.The Amur Falcon Falco amurensis performs one of the world's longest raptor migrations, involving a non‐stop crossing of the Indian Ocean of approximately 2800 km. While the existence of this route is known, the mechanistic details of wind exploitation and seasonal navigation remain to be fully elucidated.

Grasshoppers confirm mild winter [PDF]
, 2002 If we use grasshoppers as a gauge of winter severity then the winter of 2001-2002 was certainly an insect-friendly winter. I noted in the December 2001 Integrated Crop Management newsletter that a few differential grasshoppers had survived around Ames ...

Assessing the Impact of Urbanization on Grasshopper Behaviour—A Fieldwork Approach
Journal of Applied Entomology, EarlyView.ABSTRACT Urbanization is one of the most significant land‐use changes globally, profoundly impacting biodiversity across taxa. Insects, including grasshoppers (Orthoptera), are particularly sensitive to urban pressures, often exhibiting both morphological and behavioural adaptations.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.
