Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time, and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space. While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes, vast areas of the tropics remain understudied. In the American tropics, Amazonia stands out as the world's most diverse rainforest and the primary source of Neotropical biodiversity, but it remains among the least known forests in America and is often underrepresented in biodiversity databases. To worsen this situation, human-induced modifications may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities are responding. To increase generalization and applicability of biodiversity knowledge, it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lost

Effect Of Sodium Bisulfite Application On The Bed Of Broiler On Survival Of Escherichia Coli And Coliforms [efeito Da Aplicação De Bissulfato De Sódio Sobre Cama De Frangos Na Sobrevivência De Escherichia Coli E Coliformes]

The effect of sodium bisulfate has been evaluated on survival of Escherichia coli and coliforms, when applied on the broiler beds, adopting different densities. It has been adopted densities of 12, 16 and 20 birds/m 2, using inoculations of E. coli strains. The results have shown the highest microbial development on the 21 st day of inoculation, with a trend of a microbial reduction afterwards. The sodium bisulfate was efficient during the first days of analyses, reducing its efficacy during the experiment.5916569ATKINSON, C.F., JONES, D.D., GAUTHIER, J., J. biodegradability and microbial activities during composting of poultry litter (1996) Poult.

Efeito da aplicação de bissulfato de sódio sobre cama de frangos na sobrevivência de Escherichia coli e coliformes Effect of sodium bisulfite application on the bed of broiler on survival of Escherichia coli and coliforms

Avaliou-se o efeito do bissulfato de sódio, aplicado sobre a cama de frangos, criados em diferentes densidades, na sobrevivência de Escherichia coli e coliformes, utilizando-se as densidades de 12, 16 e 20 aves/m², com a inoculação de uma cepa de E. coli. Houve maior desenvolvimento microbiano no 21º dia de criação, com tendência de redução a partir daí. A eficácia do bissulfato de sódio foi maior nos primeiros dias do experimento.<br>The effect of sodium bisulfate has been evaluated on survival of Escherichia coli and coliforms, when applied on the broiler beds, adopting different densities.
