(Nature, 2022)The Octodon degus is a South American rodent that is receiving increased attention as a potential model of aging and sporadic late-onset Alzheimer's disease (AD). Impairments in spatial memory tasks in Octodon degus have ...
-
(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...
-
(MDPI, 2022)Xanthophyllomyces dendrorhous is a natural source of astaxanthin and mycosporines. This yeast has been isolated from high and cold mountainous regions around the world, and the production of these secondary metabolites ...
-
(Wiley, 2022)Investigating whether mating patterns are biased in relation to kinship in isolated populations can provide a better understanding of the occurrence of inbreeding avoidance mechanisms in wild populations. Here, we report ...
-
(MDPI, 2022)We undertook multi-proxy analyses on two sediment cores from Lago Pato, a small lake basin at 51 degrees S topographically separated from Lago del Toro in Torres del Paine (TdP), to provide insights into glacier dynamics ...
-
(Pensoft, 2021)This study provides the summary of the reports of the geographical distribution in the Maritime Antarctic and sub-Antarctic regions of Parochlus steinenii (Gercke, 1889) (Diptera, Chironomidae), the only flying insect ...
-
(Wiley, 2021)1. Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may ...
-
(MDPI, 2021)Simple Summary Triatoma infestans is the main vector of the Chagas disease transmission and has been for years one of the main sanitary problems in Bolivia, particularly for the movement between isolated population to ...
-
(BMC, 2021)Background The connection between testosterone and territoriality in free-living songbirds has been well studied in a reproductive context, but less so outside the breeding season. To assess the effects of seasonal androgenic ...
-
(Wiley, 2021)Extra-pair behavior is present in 76% of socially monogamous bird species with biparental care. This behavior may produce costs to females related to a reduction in paternal care. We estimated the percentage of extra-pair ...
-
(Wiley, 2020)Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
-
(Wiley, 2020)Globally, soils store two to three times as much carbon as currently resides in the atmosphere, and it is critical to understand how soil greenhouse gas (GHG) emissions and uptake will respond to ongoing climate change. ...
-
(Frontiers Media, 2020)High-elevation tropical lakes are excellent sentinels of global change impacts, such as climate warming, land-use change, and atmospheric deposition. These effects are often correlated with temporal and spatial beta diversity ...
-
(Oxford University Press, 2020)Over evolutionary time, pathogen challenge shapes the immunepheno type of the host to better respond to an incipient threat. The extent and direction of this selection pressure depend on the local pathogen composition, ...
-
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2020)Metridium senile is a circumboreally distributed sea anemone (Cnidaria: Anthozoa: Actiniaria) native to the northern hemisphere, and has been presumed as introduced to several locations in the southern hemisphere. Although ...
-
(Nature, 2020)Global patterns of species and evolutionary diversity in plants are primarily determined by a temperature gradient, but precipitation gradients may be more important within the tropics, where plant species richness is ...
-
(Nature, 2020)Parts of Antarctica were amongst the most rapidly changing regions of the planet during the second half of the Twentieth Century. Even so, today, most of Antarctica remains in the grip of continental ice sheets, with only ...
-
(Elsevier, 2020)By virtue of its location in the southern mid-latitudes, northwestern Patagonia (40 degrees-44 degrees S) offers the opportunity to unravel the mechanisms involved in the initiation and propagation of paleoclimate signals ...
-
(Elsevier, 2020)The first Global Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) found widespread, accelerating declines in Earth's biodiversity and associated benefits to people ...
-
(Wildlife Disease Association, 2020)No evidence of exposure to canine distemper virus (CDV) was detected in 70 samples corresponding to 58 wild-trapped Darwin's foxes (Lycalopex fulvipes) in Chile. Given its current endangered status and it being immunologically ...
