Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Importância das vacinas sintéticas contra o carrapato Rhipicephalus microplus [PDF]

open access: yesPubvet, 2015
Rhipicephalus microplus, from an economic standpoint, is the most important parasite of cattle herds in Central and South America and Australia, it causes severe direct and indirect losses in animal production. Control of this parasite rests primarily on the use of acaricides drugs that are responsible for the selection of resistant of populations and ...

In silico analysis for identification of tick phagotopes selected by phage-displayed libraries Análises in sílico na identificação de fagotopos de carrapatos selecionados por bibliotecas de phage display

open access: yesRevista Brasileira de Parasitologia Veterinária, 2009
Phage display techniques have been widely employed to map epitope structures which have served as the basis for developing molecular vaccines. We have applied this technique to map specific epitopes of Rhipicephalus (Boophilus) microplus.

New host records for Amblyomma rotundatum (Acari: Ixodidae) from Grussaí restinga, Rio de Janeiro, Brazil Novos registros de hospedeiros para Amblyomma rotundatum (Acari: Ixodidae) da restinga de Grussaí, Rio de Janeiro, Brasil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2012
Amblyomma rotundatum Koch is a parthenogenetic tick usually associated with reptiles and amphibians. However, relatively few studies on occurrences of ticks in wild reptile populations in Brazil have been produced.

Immunogenic potential of Rhipicephalus (Boophilus) microplus aquaporin 1 against Rhipicephalus sanguineus in domestic dogs

open access: yesRevista Brasileira de Parasitologia Veterinária
This study evaluated a recombinant aquaporin 1 protein of Rhipicephalus (Boophilus) microplus (RmAQP1) as antigen in a vaccine against R. sanguineus. Five dogs were immunized with RmAQP1 (10 µg) + adjuvant (Montanide) (G1), and five were inoculated with ...

Survey of canine tick-borne diseases in Lábrea, Brazilian Amazon: ‘accidental’ findings of Dirofilaria immitis infection

open access: yesRevista Brasileira de Parasitologia Veterinária, 2014
Blood samples were collected from 99 domestic dogs from the urban and rural areas of the Lábrea municipality, state of Amazonas, Brazil. Canine serum samples were tested by immunofluorescence assay against Rickettsia spp., which revealed that only 3.0 ...

Spatial capture‐recapture can improve environmental impact assessments for large carnivores

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Most Environmental Impact Assessments for large carnivores rely on summary statistics or relative abundance indices, all of which ignore imperfect detection and may lead to biased and unreliable conclusions about population status and infrastructure impacts. By applying spatial capture‐recapture (SCR) models to georeferenced genetic data from wolves in

First molecular detection of Rickettsia sp. strain Atlantic rainforest in Amblyomma ovale ticks from Espírito Santo state, Brazil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2018
Espírito Santo state (southeastern Brazil) is considered an endemic area for spotted fever group rickettsioses. In February 2017, we received in our laboratory seven unfed Amblyomma ovale adult ticks collected by a farmer from his clothes and body (not ...

Environmental DNA Template Variation: Its Relevance for Species Detection and Conservation

open access: yesFreshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Accurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk.
