Does aquaculture add resilience to the global food system? por Troell, M., Naylor, R.L., Metian, M., Beveridge, Malcolm C.M., Tyedmers, P.H., Folke, C., Arrow, K.J., Barrett, S., Crepin, A.S., Ehrlich, P.R., Gren, A., Kautsky, N., Levin, S.A., Nyborg, K., Osterblom, H., Polasky, S., Scheffer, M., Walker, B.H., Xepapadeas, T., Zeeuw, A. de

“…Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. …”

Using case studies for enhancing capacity in managing forest genetic resources por Boshier, D., Bozzano, M., Loo, J., Rudebjer, P.G., Cordero, J.

“…Lack of understanding of forest genetic resources (FGR) therefore constrains conservation of tree species, increases genetic risks in subsequent generations and hinders adaptation to climate change. Examination of tertiary forestry education curricula shows poor or no coverage of FGR issues, while biology teaching is often devoid of the social and practical realities. …”

Household Welfare Effects of Stress-Tolerant Varieties in Northern Uganda por Mwungu, Chris Miyinzi, Mwongera, Caroline, Shikuku, Kelvin Mashisia, Acosta, Mariola, Ampaire, Edidah L., Winowiecki, Leigh Ann, Läderach, Peter R.D.

“…Results showed that adoption of stress-tolerant varieties was positively influenced by household size, access to information from non-governmental organizations (NGOs), the perception of future climate change, the number of years an individual had lived in the village, and the number and type of assets owned as an indicator of household well-being. …”

Collecting wild potato species (Solanum sect. Petota) in Peru to enhance genetic representation and fill gaps in ex situ collections por Sotomayor Melo, Diego Alejandro, Ellis, David, Salas, Alberto, Gomez, Rene, Sánchez Díaz, Rosa Angélica, Carrillo Castillo, Fredesvinda, Girón Aguilar, Rita Carolina, Quispe, Violeta, Manrique Carpintero, Norma C., Anglin, Noelle L., Zorrilla Cisneros, Cinthya

“…Recent studies have shown that CWRs are threatened by several factors, including changes in land-use and climate change. A large proportion of CWRs are underrepresented in genebanks, making it necessary to take action to ensure their long-term ex situ conservation. …”

Narrow vessels cavitate first during a simulated drought in Eucalyptus camaldulensis por Barigah, Tete Severien, Gyenge, Javier, Barreto, Florencia, Rozenberg, Philippe, Fernandez, María Elena

“…Establishing drying-limits for mortality of different tree species and understanding the anatomical and physiological traits involved is crucial to predict forests' responses to climate change. The xylem of Eucalyptus camaldulensis presents a complex of solitary vessels surrounded by different imperforate tracheary elements and parenchyma that influence, in a poorly known way, its hydraulic functioning. …”

Extreme flooding increases poaching mortality in the southernmost stronghold of the endangered marsh deer por Pereira, Javier Adolfo, Varela, Diego, Thompson, Jeffrey J., Lartigau, Bernardo V., Fracassi, Natalia, Kittlein, Marcelo J.

“…Flood-related mortality significantly decreased the occurrence of the species in the study area after the flood, but changes in relative abundance between periods were heterogeneous across the landscape, probably because of local migrations. Since climate change is expected to increase the global frequency and magnitude of extreme flood events, our study provides valuable information for mitigating the negative synergistic effects of extreme flooding on marsh deer, as well as for global wildlife populations subjected to periodic extreme floods.…”
