La estructura de las comunidades de helmintos de Galaxias maculatus (Osmeriformes: Galaxiidae) en diferentes sitios de un lago de la Patagonia argentina

open access: yesEcología Austral, 2015
La variación espacial de las comunidades de helmintos en un sistema acuático puede atribuirse a diferentes factores bióticos y abióticos. En América del Sur, este tipo de estudios no ha sido realizado en ambientes de agua dulce.

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?

open access: yesJournal of Animal Ecology, Volume 93, Issue 9, Page 1338-1350, September 2024.
Sexual dimorphism in coadaptive host–parasite relationships are poorly understand. The comparative nature of the presented studied as well as the generalisation of the results for the geographic region sampled makes this study of general interest of ecologists, evolutionary biologists, physiologist and parasitologist, among others.

Pursuing Opacity: Geographies of Visibility in the Western Mediterranean

open access: yesAntipode, Volume 56, Issue 4, Page 1378-1398, July 2024.
Abstract The Moroccan and Spanish governments pursue the visibility of people and things. They observe and survey in order to codify, catalogue, classify, and calculate. Rather than trace the contours of such projects, this paper seeks to provoke a more sustained engagement with modes of errantry that confound their logics of command and control ...

The widespread keeping of wild pets in the Neotropics: An overlooked risk for human, livestock and wildlife health

open access: yesPeople and Nature, Volume 6, Issue 3, Page 1023-1035, June 2024.
Abstract Zoonoses constitute a major risk to human health. Comprehensive assessments on the potential emergence of novel disease outbreaks are essential to ensure the effectiveness of sanitary controls and to establish mitigating actions. Through a continental‐scale survey of rural human settlements conducted over 13 years in 15 Neotropical countries ...

Prevalence and diversity of avian malaria parasites in illegally traded white‐winged parakeets in Peruvian Amazonas

open access: yesAnimal Conservation, Volume 27, Issue 3, Page 364-373, June 2024.
Psittaciformes have the largest proportion of endangered species among all birds worldwide and is one of the most trafficked taxa in the pet trade. However, despite the large number of parrot species commercialized worldwide, the influence of illegally traded wild birds on the introduction of exotic pathogens is still poorly investigated. We found that

Population genomic evidence of structured and connected Plasmodium vivax populations under host selection in Latin America

open access: yesEcology and Evolution, Volume 14, Issue 3, March 2024.
Studying 1474 high‐quality genomes of P. vivax, the main cause of malaria outside Africa, reveals high global genetic diversity across 31 countries. Latin American P. vivax isolates form a unique population with sub‐populations and genetic adaptations linked to regional adaptation of the parasites to their hosts and different environmental challenges ...
