Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Genetic analysis of the infestation of females of the Caracu cattle breed by Horn Fly (Haematobia irritans irritans) (L.) (Diptera, Muscidae)

open access: yesGenetics and Molecular Biology, 2005
The objective of this study was to evaluate environmental factors that affect infestation of Caracu cattle breed by horn fly (Haematobia irritans) and to estimate genetic parameters for level of infestation.

Effect of horn fly (Diptera: Muscidae) control during the spring on calf production by fall-calving beef cows. [PDF]

open access: yes, 1995
In the spring of three consecutive years, horn fly, Haematobia irritans (L.), populations on fall-calving cows were reduced 82% for a 12-wk period using pyrethroid-impregnated ear tags.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Efeito da mosca-dos-chifres, Haematobia irritans (L.) (Diptera: Muscidae), no ganho de peso de bovinos Nelore Effects of the horn fly, Haematobia irritans (L.) (Diptera: Muscidae) in the weight gain on Nellore cattle

open access: yesCiência Rural, 2004
A presente investigação foi realizada devido à escassez, no Brasil, de informações sobre os possíveis danos decorrentes da ação hematófaga da mosca-dos-chifres, Haematobia irritans (L.), em bovinos da raça Nelore.

Pyrethroid and organophosphate pesticide resistance in field populations of horn fly in Brazil [PDF]

open access: yes, 2019
© 2018 The Royal Entomological Society Pesticides are used worldwide to control arthropod parasites in cattle herds. The indiscriminate and/or inappropriate use of pesticides without veterinary guidance is a reality in several countries of South America.

Convergent digestive adaptation to resource limitation in an insular lizard across a microgeographic archipelago

open access: yesJournal of Animal Ecology, EarlyView.
Replicated mainland–islet populations of the Skyros wall lizard reveal consistent divergence in digestive physiology, including gut morphology, passage time, digestive efficiency and enzyme activity. These results show how ecological variation in resource availability can shape digestive performance across populations in insular environments.

Horned-OWL: Flying Further and Faster with Ontologies.

open access: yesTGDK
Horned-OWL is a library implementing the OWL2 specification in the Rust language. As a library, it is aimed at processes and manipulation of ontologies, rather than supporting GUI development; this is reflected heavily in its design, which is for performance and pluggability; it builds on the Rust idiom, treating an ontology as a standard Rust ...

Digestive Enzymes in the Gut and Salivary Gland of the Adult Horn Fly Haernatobia irritans (Diptera: Muscidae) [PDF]

open access: yes, 1981
In the gut of the horn fly, significantly high proteinase activity was found in a broader pH range from 6.5 to 11.0 with pH optimum at 8.5. With reference to the substrates used, aminopeptidase (stronger), trypsin-like enzyme, carboxypeptidase A-like ...
