Behavioral Parameters of Planarians (Girardia tigrina) as Fast Screening, Integrative and Cumulative Biomarkers of Environmental Contamination: Preliminary Results por Córdova López, Ana M., De Souza Saraiva, Althiéris, Gravato, Carlos, Soares, Amadeu M. V. M., Almeida Sarmento, Renato

“…Behavioral responses are integrative and cumulative tools that reflect changes in energy allocation in organisms. Thus, feeding rate and locomotion velocity (pLMV) were determined to assess the effects induced by the laboratory exposure of adult planarians to water samples collected in the region of Tocantins-Araguaia, identifying the sampling points affected by contaminants. …”

Fading opportunities for mitigating agriculture-environment trade-offs in a south American deforestation hotspot por Law, Elizabeth A., Macchi, Leandro, Baumann, Mathias, Decarre, Julieta, Gavier Pizarro, Gregorio Ignacio, Levers, Christian, Mastrangelo, Matías Enrique, Murray, Francisco, Müller, Daniel, Piquer‐Rodriguez, María, Torres, Ricardo, Wilson, Kerrie A., Kuemmerle, Tobias

“…Finally, our results suggest the window of opportunity is closing rapidly: recent land-use changes since 2000 have rapidly moved the Chaco within the option space, with forest extent declining towards critical thresholds for maintaining balanced, multifunctional landscapes. …”

Temperature impact on the forage quality of two wheat cultivars with contrasting capacity to accumulate sugars por Lorenzo, Maximo, Assuero, Silvia Graciela, Tognetti, Jorge Alberto

“…Our results show that (i) low temperatures led to an increased hemicellulose content, in parallel with sugar accumulation; (ii) low temperatures produced negligible changes in in vitro dry matter digestibility while leading to a higher in vitro rumen gas production, especially in the higher sugar-accumulating cultivar; (iii) transferring plants from cool to warm conditions led to a sharp decrease in in vitro rumen gas production in both cultivars; and (iv) light intensity (in contrast to temperature) appeared to have a lower impact on forage quality.…”

Strategic control of Rhipicephalus (Boophilus) microplus infestation on beef cattle grazed in Panicum maximum grasses in a subtropical semi-arid region of Argentina por Morel, Nicolas, Signorini, Marcelo, Mangold, Atilio Jose, Guglielmone, Alberto, Nava, Santiago

“…The distribution of parasites among cattle in all counts was adjusted to the negative binomial distribution, but a temporal variation in the tick aggregation levels associated to changes in tick abundance was found. The higher the abundance of R. microplus, the lower the aggregation. …”

Optimizing resource productivity in soybean-based sequences through long-term crop intensification por Crespo, Cecilia, Novelli, Leonardo Esteban, Wyngaard, Nicolás, Martínez, Roberto Dionisio, Barraco, Miriam Raquel, Gudelj, Vicente Jorge, Barbagelata, Pedro Anibal, Barbieri, Pablo

“…Results: Intensification of cropping sequences increased soybean yield (17%) in one out of four sites, and did not significantly change in the other three sites. Soybean yield varied among cycles at all sites and was positively associated with rainfall during the growing season (r = 0.81). …”

Physiological and morphological short-term responses to light and temperature in two Nothofagus species of Patagonia, South America por Varela, Santiago Agustin, Fernandez, Marí­a Elena, Gyenge, Javier Enrique, Aparicio, Alejandro Gabriel, Bruzzone, Octavio Augusto, Schlichter, Tomas Miguel

“…The study of plant responses to environmental stress factors is essential for management of plant systems and for anticipating their response to climate change. The main goal of this study was to determine morphological and physiological responses of Nothofagus obliqua and N. nervosa seedlings to light and temperature, two of the main stress factors acting in their current natural distribution in NW Patagonia. …”
