When african and european lineages meet: The genetic landscape of honey bees in Argentina by Avalos, Arian, Scannapieco, Alejandra Carla, Monmany Garzia, A. Carolina, Donthu, Ravi Kiran, Marcelino, José, Giordano, Rosanna, Giray, Tugrul, Galindo Cardona, Alberto

“…We also detected trace contributions from the O lineage (Middle Eastern), highlighting Argentina's complex admixture history. Despite Argentina's diverse ecoregions, we find limited evidence for ecotype-specific differentiation, suggesting gene flow may outweigh local adaptation—though sampling limitations warrant caution. …”

Herbicide-mediated promotion of Lotus tenuis (Waldst. & Kit. ex Wild.) did not influence soil bacterial communities, in soils of the Flooding Pampa, Argentina by Nieva, Amira Susana del Valle, Bailleres, Matias Andres, Corriale, Maria Jose, Llames, María Eugenia, Menéndez, Ana Bernardina, Ruiz, Oscar Adolfo

“…At each site, two paddocks were compared, one managed to promote the forage legume L. tenuis, and the other lacking of management history and hence, covered by natural grasses. To asses bacterial diversity we used 454-FLX pyrosequencing technology of the V4 region of the 16S rRNA gene, on genomic DNA extracted from soil samples. …”

Plant size dependent response of native tree regeneration to landscape and stand variables in loblolly pine plantations in the Atlantic Forest, Argentina by Ritter, Luis Javier, Campanello, Paula Inés, Goya, Juan Francisco, Pinazo, Martin Alcides, Arturi, Marcelo Fabian

“…In this work, we analyzed the relationship between native tree density, species richness and species composition in the understory of forest plantations and stand characteristics including stand age and density, canopy openness, proximity to native forests remnants and pre-planting land use history. The study was conducted in monoculture plantations of Pinus taeda in Misiones Province, Northeastern Argentina. …”

Robles in Lagunas de Epulauquen, Argentina: previous and recent evidence of their distinctive character by Azpilicueta, Maria Marta, Pastorino, Mario Juan, Puntieri, Javier Guido, Barbero, Fernando Alvaro, Martinez Meier, Alejandro, Marchelli, Paula, Gallo, Leonardo Ariel

“…The comparison of Lagunas de Epulauquen specimens with specimens from other areas in Argentina demonstrated their genetic distinction. Glacial history, in conjunction with hybridisation processes, provides support for the main hypothesis to explain these results. …”

Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina by Mora, Matias Sebastian, Mapelli, Fernando Javier, Lopez, Aldana, Gomez Fernandez, Maria Jimena, Mirol, Patricia Monica, Kittlein, Marcelo Javier

“…Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. …”

Water-mediated changes in plant–plant and biological soil crust–plant interactions in a temperate forest ecosystem by Pissolito, Clara, Garibotti, Irene Adriana, Varela, Santiago Agustin, Arana, María Veronica, Gonzalez Polo, Marina, Marchelli, Paula, Bruzzone, Octavio Augusto

“…The aim of this study is to assess whether water availability differentially affects the biotic effects of BSCs and pioneer shrubs on the early life-history stage of tree seedling growth.We conducted a greenhouse factorial experiment with soil surface cover (bare soil, soil covered by a creeping shrub and BSC covered soil) and water regime (control and drought) as factors. …”

Bovine coronavirus in Uruguay: genetic diversity, risk factors and transboundary introductions from neighboring countries by Castells, Matias, Giannitti, Federico, Caffarena, Rubén Darío, Casaux, María Laura, Schild, Carlos, Castells, Daniel, Riet‑Correa, Franklin, Victoria, Matias, Parreño, Gladys, Colina, Rodney

“…The aim of this study was to determine the frequency of BCoV infections and their genetic diversity in Uruguayan calves and to describe the evolutionary history of the virus in South America. The overall detection rate of BCoV in Uruguay was 7.8% (64/824): 7.7% (60/782) in dairy cattle and 9.5% (4/42) in beef cattle. …”

Wolbachia pipientis associated with tephritid fruit fly pests: from basic research to applications by Mateos, Mariana, Martinez Montoya, Humberto, Lanzavecchia, Silvia Beatriz, Conte, Claudia Alejandra, Guillén, Karina, Morán-Aceves, Brenda M., Toledo, Jorge, Liedo, Pablo, Asimakis, Elias D., Doudoumis, Vangelis, Kyritsis, Georgios A., Papadopoulos, Nikos T., Augustinos, Antonios A., Segura, Diego Fernando, Tsiamis, George

“…Herein, we review the current state of knowledge on Wolbachia-tephritid interactions including infection prevalence in wild populations, phenotypic consequences, and their impact on life history traits. Numerous pest tephritid species are reported to harbor Wolbachia infections, with a subset exhibiting high prevalence. …”

Immobilization and stabilization of volcanic ash in soil aggregates in semiarid meadows of Northern Patagonia by Enriquez, Andrea Soledad, Necpalova, Magdalena, Cremona, Maria Victoria, Peri, Pablo Luis, Six, Johan

“…Here, we studied processes of soil aggregates formation in the buried ash layer in an early stage of the succession as well as the influence of the biological legacy (previous land management history) on these processes after the 2011 volcanic event of the Puyehue–Cord´on Caulle Volcanic Complex. 5.5 years after the eruption we collected soil cores to a 10 cm depth in wet and mesic meadows with good and poor grassland conditions induced by light and heavy grazing intensity, respectively, in the East semiarid region of North Patagonia, Argentina. …”

How is soil carbon stock in old-growth boreal forests affected by management? by Dahl, Jenny

“…Boreal forests are able to store large amounts of carbon in soil and biomass, and forest management is considered an important strategy for mitigating climate change. Sweden has a long history of forest management that have intensified during the last century, but there are still old-growth forests that have not been disturbed by management. …”
