Reproductive biology of cassava (Manihot esculenta Crantz) and isolation of experimental field trials por Halsey, ME, Olsen, KL, Taylor, Nigel J., Chavarriaga Aguirre, Paul

“…With the current state of knowledge on gene flow and seed dormancy in cassava, three methods for reproductive isolation of regulated experimental plots may currently be recommended: (i) removal of flower buds before flowering, (ii) destruction of plants before flowering, and (iii) floral bagging to contain pollen and seed. Areas for further research in cassava biology and biosafety are suggested.…”

Extinction filters mediate the global effects of habitat fragmentation on animals por Betts, Matthew G., Wolf, Christopher, Pfeifer, Marion, Banks-Leite, Cristina, Arroyo Rodríguez, Víctor, Bandini Ribeiro, Danilo, Barlow, Jos, Eigenbrod, Félix, Faria, Deborah, Somarriba, Eduardo

“…We tested the hypothesis that forest fragmentation sensitivity— affected by avoidance of habitat edges—should be driven by historical exposure to, and therefore species’ evolutionary responses to disturbance. Using a database containing 73 datasets collected worldwide (encompassing 4489 animal species), we found that the proportion of fragmentation-sensitive species was nearly three times as high in regions with low rates of historical disturbance compared with regions with high rates of disturbance (i.e., fires, glaciation, hurricanes, and deforestation). …”

The waste of time – how a lower opportunity cost could increase households’ recycling effort : an empirical analysis of the effect of curbsiderecycling on waste sorting efforts in... por Hoff Rudhult, Linda

“…In Sweden, three different systems for curbside collection are used for waste sorting; four-compartment bins, different coloured bags, and bags and containers. The purpose of this study is to empirically evaluate curbside recycling program and to estimate the change in waste sorting effort in Swedish municipalities when residents living in single-family houses makes a transition from drop-off recycling to curbside recycling of packaging waste and newspaper. …”

Välkommen : förslag till ny stadspark i Göteborg por Eriksson, Louise

“…The reason for choosing this place is that it is the only area around the costal area in Göteborg that has not been built on and that it contains a very varied landscape. The proposal is presented as three different broschures, dated 10-20 years ahead: A map of a possible system of urban parks including a detail of such a park, Västra Hisingen (the western parts of Hisingen) The idea with a system of urban parks is to make the landscape generally more accessible and maybe open it for people that do not use it today. …”
