Consensus guidelines for the use and interpretation of angiogenesis assays
The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference

Ormiscodes outbreaks dynamics: Impacts and perspectives in a warming world
Changes in the frequency and magnitude of insect outbreak appear to be occurring worldwide, but research has been mainly focused on northern hemisphere forests. In the temperate forests of the southern Andes, Nothofagus tree species experience severe defoliation caused by Ormiscodes caterpillars (Lepidoptera: Saturniidae). Current impacts of defoliation on tree health are relatively low and short term. Although relationships between Ormiscodes outbreaks and climate proved to be complex, defoliation events are generally associated with drier and warmer than average growing seasons. However, these probable climatic influences on outbreak occurrence are contingent on the sensitivity of Nothofagus and Ormiscodes to temperature and precipitation along environmental gradients. Relationships between Ormiscodes outbreaks and climate suggest that under predicted warmer and drier climates in the twenty-first century, these defoliator outbreaks may become more frequent and contribute to future forest decline in Nothofagus forests.Fil: Paritsis, Juan.
