Integrative revision of the Australian carrion‐breeding Calliphorinae (Diptera: Calliphoridae): Revision of the Calliphora stygia‐ and ochracea‐groups

open access: yesMedical and Veterinary Entomology, EarlyView.
The Australian carrion‐breeding Calliphorinae are revised using an integrative approach combining morphology and mitogenomics. A new taxonomic key, morphological images and verified mitogenomic data, including COX1 barcodes, are provided to support the identification of species.

Evolution of proboscis musculature in Lepidoptera

open access: yesEuropean Journal of Entomology, 2004
The suctorial proboscis of adult Lepidoptera represents a key morphological innovation that enabled these insects to gain access to new food sources. In the ancestral condition of the lepidopteran proboscis only extrinsic galeal muscles are present in ...

Effectiveness of different blood anticoagulants for artificial feeding of Aedes aegypti mosquitoes in the laboratory Eficiência de diferentes anticoagulantes para alimentação sanguínea artificial de mosquitos Aedes aegypti em laboratório

open access: yesMedical and Veterinary Entomology, EarlyView.
Aedes aegypti females were allowed to feed, through an artificial feeder, on rabbit blood pre‐collected and defibrinated or treated with anticoagulants heparin or sodium citrate. The efficiency in producing a high percentage of engorged females and great fecundity and egg viability rates was compared among blood treatments and with females feeding ...

Antenatally diagnosed alobar holoprosencephaly: A report of two cases

open access: yesCHRISMED Journal of Health and Research, 2017
Holoprosencephaly is a complex developmental abnormality of the brain arising from the failure of cleavage of the prosencephalon. The condition termed “holoprosencephaly” includes cyclopia, cebocephaly, ethmocephaly, and median cleft.

Effects of essential amino acids on phagostimulation and reproduction in adults of the Mediterranean fruit fly Efectos de amino ácidos esenciales en la fago‐estimulación y reproducción en adultos de la mosca de las frutas del Mediterráneo

open access: yesPhysiological Entomology, EarlyView.
The phagostimulation and reproductive effects of individual essential amino acids, without other nutrient except fructose, were investigated. Methionine, Arginine and Leucine display significantly higher phagostimulation strength than fructose. Arginine and Methionine showed a significant improvement in reproductive activity compared to other tested ...

Size-associated Variation and Factors Affecting the Morphology of Brown Bodies in Glycera tridactyla (Polychaeta:Glyceridae)

open access: yesBrazilian Archives of Biology and Technology, 2014
Size-associated variations in brown body morphology (size and shape) were studied from the individuals of Glycera tridactyla. Variables related to size, length (BL) and width (BW) of the brown bodies were measured.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

open access: yesPlant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

A dual pollination strategy combining perfume attraction and food deception in Galeandra blanchetii E.S. Rand (Orchidaceae)

open access: yesPlant Biology, EarlyView.
Galeandra blanchetii exhibits a dual‐attraction strategy: male euglossine bees are lured by floral scents as a resource, while both sexes are deceived by non‐existent nectar. Pollination only occurs when bees enter the spur to search for nectar, highlighting an evolutionary transition towards the perfume flower syndrome in Catasetinae.

Morphology, biostratigraphy, and evolution of Pliocene-Pleistocene diatoms Proboscia barboi and Proboscia curvirostris

open access: yesGeologica Acta, 2019
Proboscia barboi and Proboscia curvirostris are two important diatom biostratigraphic markers from the high latitudes of the North Pacific and North Atlantic Oceans, dating back to the Pliocene-Pleistocene time.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2790-2837, October 2026.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
