Sexual dimorphism in the structural colours of the wings of the black soldier fly (BSF) Hermetia illucens (Diptera: Stratiomyidae)

open access: yesScientific Reports
The black soldier fly (BSF) Hermetia illucens (Diptera: Stratiomyidae) plays a significant role at the larval stage in the circular economy due to its ability to convert organic waste into valuable products for energy, food, feed, and agricultural ...

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Latitudinal gradient in response of wing polymorphism to photoperiod in a flightless bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2001
The aim of this study was to determine if there is a latitudinal gradient in the photoperiodic regulation of wing dimorphism in the flightless bug, Pyrrhocoris apterus (L.).

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

open access: yesIbis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Life history correlates of adult size in the malaria vector Anopheles darlingi

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
Adult dry weights of laboratory-reared Anopheles darlingi were highly correlated with wing lengths, which were used to estimate size variation in natural populations of this species.

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Stable isotopes reveal dietary divergence between dispersal phenotypes in Tetrix subulata pygmy grasshoppers (Orthoptera: Tetrigidae)

open access: yesEuropean Journal of Entomology, 2013
In some species of insects, individuals with fully developed wings and capable of flying coexist with flightless individuals that lack functional wings.

Sexual selection in the Swallow Hirundo rustica - A review [PDF]

open access: yes, 2005
Darwinian theory of sexual selection and its development up to the present state of knowledge are sketched. The most important results of empirical studies on sexual selection in the Swallow Hirundo rustica are reviewed.

A new species of inseminating catfish of the genus Tympanopleura (Siluriformes: Auchenipteridae) from the Ituxi River, Amazon River basin, northern Brazil, revealed by integrative taxonomy

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...
