Identifizierung und Analyse von Ecdysteroid synthetisierenden Zellen mithilfe eines hämolytischen Plaque Assays [PDF]

open access: yes, 2005
Ecdysteroide spielen eine entscheidende Rolle in der hormonellen Regulation der Entwicklung von Arthropoden. Sie werden von einer spezialisierten Hormondrüse, der so genannten Prothorakaldrüse, sezerniert.

Contrasted effects of human pressure on biodiversity in the UK: a multi‐taxonomic assessment using airborne environmental DNA

open access: yesEcography, Volume 2025, Issue 12, December 2025.
Human activities have significantly modified habitats, resulting in a global biodiversity crisis. In this study, we leveraged the first national‐scale biodiversity survey based on airborne environmental DNA, comparing the effects of three human pressure indices increasing in complexity and scope – a binary urban–rural index, an index integrating land ...

Effect of Temperature on the Rate of Ageing: An Experimental Study of the Blowfly Calliphora stygia

open access: yesPLoS ONE, 2013
All organisms age, the rate of which can be measured by demographic analysis of mortality rates. The rate of ageing is thermally sensitive in ectothermic invertebrates and we examined the effects of temperature on both demographic rates of ageing and on ...

Sensory Enrichment and Deprivation During Development: Limited Effects on the Volumes of CNS Neuropils in Two Spiders With Different Ecology

open access: yesJournal of Comparative Neurology, Volume 533, Issue 11, November 2025.
Sensory enrichment did not increase modality‐specific brain region volumes in either Parasteatoda tepidariorum or Marpissa muscosa; variation was largely explained by shared maternal origin, suggesting that genetic or developmental factors may outweigh environmental sensory input in shaping spider brain structure.

Habitat and seasonal effects on blowfly ecology in possum carcasses in the Manawatu : a thesis presented in partial fulfilment for the requirements for the degree of Master of Science in Ecology at Massey University [PDF]

open access: yes, 1993
Flies were trapped on Keeble farm and in Keeble forest reserve between May 1992 to February 1993. Fewer Calliphoridae were trapped in pasture during summer than in autumn or winter and different fly species showed differing preferences for bush or ...

At the edge of darkness: A framework for the evolution of visual systems in dim light

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2626-2636, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Light is an important biological cue for all living things. For animals, where many behaviours are driven by sensory input from the eyes, light is also a critical environmental feature shaping animal eye evolution, with the intensity of light (i.e.

Impact of confinement in vehicle trunks on decomposition and entomological colonization of carcasses.

open access: yesPLoS ONE, 2020
In order to investigate the impact of confinement in a car trunk on decomposition and insect colonization of carcasses, three freshly killed pig (Sus scrofa domesticus Erxleben) carcasses were placed individually in the trunks of older model cars and ...

Silver gull carcasses host unique carrion insect communities on a nearshore island

open access: yesAustral Entomology, Volume 64, Issue 3, August 2025.
Abstract Island ecosystems offer unique opportunities to study the dynamics of species that rely on ephemeral resources such as carrion. This study investigated the necrophagous insect communities associated with carrion of silver gulls (Chroicocephalus novaehollandiae) on a small nearshore island off the east coast of Australia, to assess how ...

Molecular and Pharmacological Characterization of Serotonin 5-HT2α and 5-HT7 Receptors in the Salivary Glands of the Blowfly Calliphora vicina

open access: yesPLoS ONE, 2012
Secretion in blowfly (Calliphora vicina) salivary glands is stimulated by the biogenic amine serotonin (5-hydroxytryptamine, 5-HT), which activates both inositol 1,4,5-trisphosphate (InsP3)/Ca2+ and cyclic adenosine 3′,5′-monophosphate (cAMP) signalling ...

Lords of the flies: dipteran migrants are diverse, abundant and ecologically important

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1635-1659, August 2025.
ABSTRACT Insect migrants are hugely abundant, with recent studies identifying the megadiverse order Diptera as the major component of many migratory assemblages. Despite this, their migratory behaviour has been widely overlooked in favour of more ‘charismatic’ migrant insects such as butterflies, dragonflies, and moths.
