Helminth community from Azara's grass mouse (Akodon azarae) in three habitats with different land use in farming systems of Argentina

et al. 2018

In the Pampa region of Argentina, farming activities have been performed since the beginning of the 20th century, but in the 1990s, land-use patterns rapidly changed towards intensive agriculture and poultry breeding. This study compares the helminth community of Akodon azarae (Rodentia) among three habitats with different land use in pampean agroecosystems: poultry farms, mono-cultivated fields and abandoned fields (not used for 35 years), under the prediction that there will be greater helminth richness and diversity in mice from abandoned fields compared to those from the other habitats. Nevertheless, the highest abundance of A. azarae occurred on poultry farms, the habitat most disturbed by human activity, while cultivated fields showed the lowest. Helminth richness and diversity were significantly higher on poultry farms than in the other habitats, due to the presence of Trichuris laevitestis, Protospirura numidica criceticola and cysts of Taenia taeniaeformis. We suggest that the helminth fauna of A. azarae can survive on poultry farms despite disturbance from farming activities, because rodents can move and get shelter within farm perimeter fences, where dense and high vegetation grows. This farm area could offer good conditions for geohelminth development, while chicken sheds could attract insects that are intermediate hosts of helminths with indirect life cycles. On the contrary, agrochemicals applied in cultivated fields would negatively influence helminth diversity and composition, by decreasing host populations (arthropods and rodents) and affecting free larval stages of geohelminths.

Environmental drivers of long‐term variations in the abundance of the red hocicudo mouse (Oxymycterus rufus) in Pampas agroecosystems

During the 20th century, there has been an ongoing agricultural expansion and global warming, two of the main determinants influencing biodiversity changes in Argentina. The red hocicudo mouse (Oxymycterus rufus) inhabits subtropical grasslands and riparian habitats and has increased its abundance in recent years in central Argentina agroecosystems. This paper describes the long‐term temporal changes in O. rufus abundance in Exaltación de la Cruz department, Buenos Aires province, Argentina, in relation to weather fluctuations and landscape features, as well as analyzes the spatio‐temporal structure of captures of animals. We used generalized liner models, semivariograms, the Mantel test, and autocorrelation functions for the analysis of rodent data obtained from trappings conducted between 1984 and 2014. O. rufus showed an increase in abundance across the years of study, with its distribution depending on landscape features, such as habitat types and the distance to floodplains. Capture rates showed a spatio‐temporal aggregation, suggesting expansion from previously occupied sites. O. rufus was more abundant at lower minimum temperatures in summer, higher precipitation in spring and summer, and lower precipitations in winter. Weather conditions affected O. rufus abundance, but there was local variation that differed from global patterns of climate change.

The honey locust (Gleditsia triacanthos) is one of the most aggressive tree invaders of savannas and grasslands worldwide. The objective of the study was to determine whether landscape elements could act as potential determinants on honey locust invasion of woodlots of an agricultural matrix of the Pampean ecoregion. Specifically, we assessed the effect of distance to the previously established woodlots, to corridors such as riparian habitats, railway terraces and roads, and the presence of livestock and land use through generalized linear models. The study was carried out in a rural area of the Exaltaci on de la Cruz Department of the Buenos Aires Province (34°19' S and 59°14' W), located in the Pampean ecoregion, in the Rolling Pampa complex, Argentina. In each woodlot, the presence or absence of honey locust and the number of individuals intercepted along line transects were recorded. Furthermore, the presence of cattle and the land use around the woodlot were registered. All woodlots were geo-positioned to calculate distances to landscape elements of interest. According to our results, the colonization capacity and the abundance of honey locust increases as distance to the nearest woodlot with the presence of the species decreases, suggesting that propagule pressure is a key factor for honey locust invasion. Also, cattle promote the increase in the abundance of the species in woodlots of the agricultural system studied. The probability of presence was also increased with the proximity to main roads and decreased with the proximity to the nearest human settlement. Our results highlight the importance of reducing the abundance of the species in invaded woodlots and cattle pathways and in case of moving animals from an invaded to a non-invaded area. It is also recommended to maintain animals in quarantine before transporting them in order to allow animals to eliminate honey locust seeds.
