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

Journal 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 ...

Tripanosomatídeos similares a Trypanosoma theileri no carrapato dos bovinos Boophilus microplus [PDF]
Revista Brasileira de Parasitologia Veterinária, 2008 Descreve-se a ocorrência de formas epimastigotas de um tripanosomatideo na hemolinfa do carrapato do bovino Boophilus microplus no Estado do Rio Grande do Sul. Evidências morfológicas sugerem tratar-se de Trypanosoma theileri , espécie descrita como não patogênica aos bovinos e que usualmente é transmitida por tabanídeos.

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

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