Socio-technical networks in rural contexts: Analysing shearing schedules and functioning in Patagonian sheep farming por Gonzalez, Ezequiel Bernardo, Easdale, Marcos Horacio, Crovetto, Maria Marcela

“…While some prioritised efficiency by maximizing work volume in fewer farms with shorter travel times, others adapted to wider temporal and geographical scopes. This highlights the complex interplay between socio-technical configurations and performance outcomes in scheduling implementation. …”

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

“…“chasiquensis” are moderate structured at regional level and this population pattern is probably the result of an asymmetric historical gene flow essentially from the South-West to the North-West, further of a recent demographic population expansion in the North-West, in conjunction with an important degree of isolation in some populations over its eastern geographical range. Evidently, historical gene flow seems to have been more frequently on the West. …”

Pathogenic diversity of soybean rust in Argentina, Brazil, and Paraguay por Akamatsu, Hajime, Yamanaka, Naoki, Yamaoka, Yuichi, Soares, Rafael Moreira, Morel, Wilfrido, Ivancovich, Antonio Juan, Bogado, Alicia Noelia, Kato, Masayasu, Yorinori, José Tadashi, Suenaga, Kazuhiro

“…This study demonstrated that P. pachyrhizi populations from South America vary geographically and temporally in pathogenicity and that the known Rpp genes other than Rpp1 in PI 587880A and Rpp5 have been less effective against recent pathogen populations in the countries studied.…”

Genetic studies of various Prosopis species (Leguminosae, Section Algarobia) co- occurring in oases of the Atacama Desert (northern Chile) por Bessega, Cecilia, Pometti, Carolina, Fortunato, Renee Hersilia, Greene, Francisca, Santoro, Calogero M., McRostie, Virginia

“…Pairwise differentiation comparisons among populations showed inconsistencies considering their distribution throughout the basins. Genetic and geographic distances were significantly correlated at global and within the basins considered (p < .02), but low correlation indices were obtained (r < .37). …”

The scale insect (Hemiptera: Coccomorpha) collection of the entomological museum “Universidad Nacional Agronomía Bogotá”, and its impact on Colombian coccidology por Caballero, Alejandro, Ramos Portilla, Andrea Amalia, Rueda Ramírez, Diana, Vergara Navarro, Erika Valentina, Serna, Francisco

“…Host-insect interaction analysis has shown that coffee is the host-plant with the largest number of associated scales, Rhizoecus cacticans (Hambleton, 1946) and Rh. colombiensis Ramos & Caballero, 2016 are the scale species with the largest host-plant range; and Geococcus coffeae Green, 1933 and Puto barberi (Cockerell, 1895) are the commonest scale species. Altitudinal and geographic distribution analysis have shown that sampling efforts have been concentrated in the central region, while the northern and southeastern regions of Colombia have been poorly collected. …”
