Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Risk factors for visceral leishmaniasis in a new epidemic site in Amhara Region, Ethiopia [PDF]
, 2009 We conducted a case-control study to evaluate risk factors for visceral leishmaniasis during an epidemic in a previously unaffected district of Ethiopia. We also collected blood and bone marrow specimens from dogs in the outbreak villages.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans
Integrative Zoology, EarlyView.Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use
Agricultural and Forest Entomology, EarlyView.Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Identification of microorganisms in partially fed female horn flies, Haematobia irritans
Parasitology Research, 2012 The horn fly Haematobia irritans (Linnaeus, 1758) (Diptera: Muscidae) is one of the most important ectoparasites of cattle. The parasitism of horn flies interferes with cattle feeding, thus reducing weight gain and milk production. Additionally, horn flies are mechanical vectors of pathogens that cause disease in cattle.

Morphological re-description and molecular identification of Tabanidae (Diptera) in East Africa [PDF]
, 2018 Biting flies of the family Tabanidae are important vectors of human and animal diseases across continents. However, records of Africa tabanids are fragmentary and mostly cursory.

Who Makes the Far Right? Exploring Membership Application Data of the National Front of Australia
Australian Journal of Politics &History, EarlyView.This paper addresses a problem for scholars examining the question of who supports far right political parties or movements. Due to the semi‐clandestine or oppositional nature of far right groups, historians, as well as those in adjacent disciplines, have often been unable to gain access to sufficient records or data to conduct analysis of who supports

Revista Brasileira de Parasitologia Veterinária, 2009 To investigate the kdr (knockdown resistance) resistance-associated gene mutation and determine its frequency in pyrethroid-resistant horn fly (Haematobia irritans) populations, a total of 1,804 horn flies of 37 different populations from all Brazilian ...

Effect of Horn Flies on Vanilmandelic Acid Excretion of Dairy Cattle
Journal of Dairy Science, 1976 This study measured a physiological effect of known horn fly (Haematoba irritans L.) population densities on dairy cattle. Urinary excretion of the catecholamine metabolite, 3-methoxy-4-hydroxy mandelic acid, was an indicator of physiological response to the parasites. Six lactating Holstein cows were acclimated to the test room prior to a 3-wk control
