Ocurrencia del ácaro ectoparásito del género Ornithonyssus Sambon, 1928 (Mesostigmata: Macronyssidae) como potencial vector de enfermedades zoonóticas en roedores sigmodontinos (Cricetidae: Sigmodontinae) de la región andina, Perú

Neotropical helminthology
Los ácaros de la familia Macronyssidae Oudemans, 1936 son ectoparásitos de reptiles, aves y mamíferos, especialmente murciélagos y roedores. A pesar de ser una familia de importancia zoonótica y veterinaria, aún hay zonas en Perú donde no se ha abordado ...

Chromosomal rearrangements played an important role in the speciation of rice rats of genus Cerradomys (Rodentia, Sigmodontinae, Oryzomyini). [PDF]

Sci Rep
Rodents of the genus Cerradomys belong to tribe Oryzomyini, one of the most diverse and speciose groups in Sigmodontinae (Rodentia, Cricetidae). The speciation process in Cerradomys is associated with chromosomal rearrangements and biogeographic dynamics

Hassalstrongylus dollfusi (Nematoda, Heligmonellidae): rediscovery in native South American rodents, six decades after its description

Parasite, 2021
Hassalstrongylus dollfusi (Díaz-Ungría, 1963) Durette-Desset, 1971 was described in a wild house mouse, Mus musculus, from Venezuela and, since then, has never been reported again in the type host or in any other host.

A New Species of Heligmonellidae (Nematoda) in Euryoryzomys russatus (Rodentia: Sigmodontinae) in the Atlantic Forest of Northeast Brazil. [PDF]

Acta Parasitol
The genus Stilestrongylus (Freitas, Lent, and Almeida, 1937) is defined by having 24 or more subequal cuticular ridges, an asymmetrical caudal bursa, and a hypertrophied genital cone. It comprises 25 recognized species, mainly parasitizing cricetids, and

Systematics and diversification of the Ichthyomyini (Cricetidae, Sigmodontinae) revisited: evidence from molecular, morphological, and combined approaches. [PDF]

PeerJ, 2023
Ichthyomyini, a morphologically distinctive group of Neotropical cricetid rodents, lacks an integrative study of its systematics and biogeography. Since this tribe is a crucial element of the Sigmodontinae, the most speciose subfamily of the Cricetidae ...

Extensive Chromosomal Reorganization in the Evolution of New World Muroid Rodents (Cricetidae, Sigmodontinae): Searching for Ancestral Phylogenetic Traits. [PDF]

PLoS ONE, 2016
Sigmodontinae rodents show great diversity and complexity in morphology and ecology. This diversity is accompanied by extensive chromosome variation challenging attempts to reconstruct their ancestral genome.

Challenges with the current methodology for conducting Endangered Species Act risk assessments for pesticides in the United States

Integrated Environmental Assessment and Management, Volume 19, Issue 3, Page 817-829, May 2023., 2023
Abstract The US Environmental Protection Agency (USEPA or the Agency) is responsible for administering the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The Agency is also required to assess the potential risks of pesticides undergoing registration or re‐registration to threatened and endangered (i.e., listed) species to ensure ...

Disentangling direct from indirect effects of habitat disturbance on multiple components of biodiversity

Journal of Animal Ecology, Volume 91, Issue 11, Page 2220-2234, November 2022., 2022
Given that anthropogenic disturbance is one of the most important factors influencing ecological communities, a better understanding of the reciprocity of the various components of biodiversity is needed to predict the development of disturbed natural communities.

Cave use by the Broad-footed Climbing Rat Rhipidomys latimanus (Tomes, 1860) in Santander, Colombia.

Mammalogy Notes, 2020
In this note, I report two field observations of R. latimanus using caves. These records provide new data about the natural history of R. latimanus, previously, this species was considered mainly arboreal and solitary.

The influence of sugarcane pre‐harvest fire on hantavirus prevalence in Neotropical small mammals

Ecosphere, Volume 13, Issue 9, September 2022., 2022
Abstract The use of pre‐harvest fire in sugarcane fields surprisingly results in an increase in the abundance of Neotropical Sigmodontinae rodents, which might carry hantavirus. By contrast, fire suspension induces a decline in rodents in the first 5 years.
