Voicing Rivers through ontopoetics:A co-operative inquiry

A co-operative inquiry was established to explore the experience of a panpsychic world of sentient beings rather than inert objects, a world in which mind—sentience, subjectivity, and the will of self-realization—is a fundamental aspect of matter, just as matter is a fundamental aspect of mind. The nature of worldviews, the fundamental basis of our perceiving, thinking, valuing, and acting, is addressed and a brief outline of living cosmos panpsychism offered. The inquiry asks, could we humans, through intentional engagement, relate to the rivers as beings, subjects, or other-than-human persons in their own right? How might we engage with the rivers through personal relationship, ceremony, and invocation? What are the possibilities for reciprocal communication? In short, how might rivers speak?.</p

Temporal abundance of Aedes aegypti in Manaus, Brazil, measured by two trap types for adult mosquitoes

A longitudinal study was conducted in Manaus, Brazil, to monitor changes of adult Aedes aegypti (L.) abundance. The objectives were to compare mosquito collections of two trap types, to characterise temporal changes of the mosquito population, to investigate the influence of meteorological variables on mosquito collections and to analyse the association between mosquito collections and dengue incidence. Mosquito monitoring was performed fortnightly using MosquiTRAPs (MQT) and BG-Sentinel (BGS) traps between December 2008-June 2010. The two traps revealed opposing temporal infestation patterns, with highest mosquito collections of MQTs during the dry season and highest collections of BGS during the rainy seasons. Several meteorological variables were significant predictors of mosquito collections in the BGS. The best predictor was the relative humidity, lagged two weeks (in a positive relationship). For MQT, only the number of rainy days in the previous week was significant (in a negative relationship). The correlation between monthly dengue incidence and mosquito abundance in BGS and MQT was moderately positive and negative, respectively. Catches of BGS traps reflected better the dynamic of dengue incidence. The findings help to understand the effects of meteorological variables on mosquito infestation indices of two different traps for adult dengue vectors in Manaus
