Potential pollinator of Vanda falcata (Orchidaceae): Theretra (Lepidoptera: Sphingidae) hawkmoths are visitors of long spurred orchid

open access: yesEuropean Journal of Entomology, 2015
Vanda falcata is a species of orchid native to China, Korea and Japan. While it is arguably one of the most celebrated orchids in Japan there is no information on its pollinators. Although most species of the subtribe Aeridinae, to which V.

Octopamine regulates antennal sensory neurons via daytime-dependent changes in cAMP and IP3 levels in the hawkmoth Manduca sexta. [PDF]

open access: yesPLoS ONE, 2015
The biogenic amine octopamine (OA) mediates reward signals in olfactory learning and memory as well as circadian rhythms of sleep and activity. In the crepuscular hawkmoth Manduca sexta, OA changed pheromone detection thresholds daytime-dependently ...

Vortical Structure and Aerodynamics of Hawkmoth Hovering

open access: yesJournal of Biomechanical Science and Engineering, 2006
A multi-block-and overset grid-based computational fluid dynamic (CFD) study is conducted for the unsteady flows about a realistic body-wing model and the force-generation in the flapping flight of hawkmoth hovering.

Armament imbalances: match and mismatch in plant-pollinator traits of highly specialized long-spurred orchids. [PDF]

open access: yesPLoS ONE, 2012
Some species of long-spurred orchids achieve pollination by a close association with long-tongued hawkmoths. Among them, several Habenaria species present specialized mechanisms, where pollination success depends on the attachment of pollinaria onto the ...

The vortex wake of a ‘hovering’ model hawkmoth

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1997
Visualization experiments with Manduca sexta have revealed the presence of a leading–edge vortex and a highly three–dimensional flow pattern. To further investigate this important discovery, a scaled–up robotic insect was built (the ‘flapper’) which could mimic the complex movements of the ...

Historic DNA for taxonomy and conservation: A case-study of a century-old Hawaiian hawkmoth type (Lepidoptera: Sphingidae). [PDF]

open access: yesPLoS ONE, 2017
Analysing historic DNA from museum specimens offers the unique opportunity to study the molecular systematics and phylogenetics of rare and possibly extinct taxa.

Pollinator risks and recovery from air pollutant interactions during the fossil‐fuel transition

open access: yesFrontiers in Ecology and the Environment, EarlyView.
By altering the composition and concentration of floral scents, air pollutants such as ozone (O3) and nitrogen oxides (NOx) disrupt the ability of insect pollinators to locate flowers, threatening biodiversity and crop production. We examine the impact of these pollutants on pollinator performance and evaluate the short‐ and long‐term consequences of ...

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

open access: yesIbis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Ambition without alignment: Pollinators in the EU Nature Restoration Law

open access: yesReview of European, Comparative &International Environmental Law, EarlyView.
Abstract Pollinators are essential for life on Earth. They enable the reproduction of most flowering plants and support biodiversity as well as food systems. However, their numbers are in great decline. Research finds a continuing decrease in pollinating insects each year. This article reviews whether EU Law is fit to address this challenge.
