The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

open access: yesPest Management Science, EarlyView.
The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

Dual RNA-Seq Analysis Reveals Transcriptome Effects during the Salmon–Louse Interaction in Fish Immunized with Three Lice Vaccines

open access: yesVaccines, 2022
Due to the reduced efficacy of delousing drugs used for sea lice control in salmon aquaculture, fish vaccines have emerged as one of the most sustainable strategies in animal health. Herein, the availability of C.

Prevalence and drivers of ectoparasite abundance on Norway rats (Rattus norvegicus) in New York City residential complexes

open access: yesPest Management Science, EarlyView.
Norway rat ectoparasite burden varied by residential microhabitat, host traits, and trap type, showing that urban rodent management should address both rat burden and ectoparasite persistence in residential buildings. Abstract BACKGROUND Norway rats, Rattus norvegicus (Berkenhout), can carry ectoparasites of public health importance.

Disease of South American camelids in England and Wales: Analysis of diagnoses from Animal and Plant Health Agency laboratory submissions between 2012 and 2021

open access: yesVeterinary Record, EarlyView.
Abstract Background South American camelids (SACs) have become increasingly popular in the UK. Consequently, knowledge among veterinary practitioners about diseases in these non‐native species has improved, although gaps remain. The remit of this study was to identify common diseases of SACs based on Animal and Plant Health Agency (APHA) surveillance ...

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Salmon lice loads on Atlantic salmon smolts associated with reduced welfare and increased population mortalities

open access: yesAquaculture Environment Interactions, 2023
Modelling potential impacts of salmon lice Lepeophtheirus salmonis on Atlantic salmon Salmo salar requires estimation of the levels that cause serious sub-lethal physiological impacts and direct mortality.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Monitoring parasitic abundance in cage-based aquaculture : the effects of clustering [PDF]

open access: yes, 2006
Most discussions of sampling protocols within the literature on monitoring aquatic parasites are based on the assumptions of simple random sampling. There has been a growing recognition within the fields of human and terrestrial veterinary epidemiology ...
