Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

open access: yesEnvironmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

Native rodent species are unlikely sources of infection for Leishmania (Viannia) braziliensis along the Transoceanic Highway in Madre de Dios, Peru. [PDF]

open access: yes, 2014
An estimated 2.3 million disability-adjusted life years are lost globally from leishmaniasis. In Peru's Amazon region, the department of Madre de Dios (MDD) rises above the rest of the country in terms of the annual incidence rates of human leishmaniasis.

Two rodent suborders have evolved missing amino acids in the lipid-binding region of apolipoprotein E. [PDF]

open access: yesLipids
Abstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.

Aligning conservation and public health goals to tackle unsustainable trade of mammals

open access: yesConservation Science and Practice, Volume 4, Issue 11, November 2022., 2022
Abstract Unsustainable wildlife trade is a major driver of biodiversity loss and an important public health threat. Yet, effective wildlife trade regulation is currently at odds with food security and economic incentives provided by this global, multibillion‐dollar industry.

Behavioral repertoire of the Brazilian spiny-rats, Trinomys setosus and Clyomys laticeps: different levels of sociality

open access: yesBrazilian Journal of Biology, 2021
Behavior is a useful trait for comparative studies that provide the comprehension of phylogenetic relationships among species. Here, we present a description of two spiny-rats species’ behavioral repertoire, Clyomys laticeps and Trinomys setosus ...

Paleodietary reconstruction of endemic rodents from the precolumbian Dominican Republic: Discriminating wild feeding behavior from diets linked to human niche construction activities

open access: yesInternational Journal of Osteoarchaeology, Volume 32, Issue 5, Page 976-995, September/October 2022., 2022
Abstract In the Greater Antilles, certain animal taxa that have long been theorized to have been managed by indigenous peoples prior to AD1492, the main candidates being a group of endemic caviomorph rodents known as hutias (Capromyinae). This isotopic study investigates the paleodiets of several species of endemic rodents from three late precolonial ...

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

open access: yesGeo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

The mutualism–antagonism continuum in Neotropical palm–frugivore interactions: from interaction outcomes to ecosystem dynamics

open access: yesBiological Reviews, Volume 97, Issue 2, Page 527-553, April 2022., 2022
ABSTRACT Frugivory, that is feeding on fruits, pulp or seeds by animals, is usually considered a mutualism when interactions involve seed dispersal, and an antagonism when it results in the predation and destruction of seeds. Nevertheless, most frugivory interactions involve both benefits and disadvantages for plants, and the net interaction outcomes ...
