Os habitats de inovação surgem como instrumentos incentivo à geração inovações a criação ambientes que possuem características tecnológicas, neste contexto emerge importância das universidades na conversão da ciência em tecnologia. Assim, novos modelos são criados, por exemplo o modelo aberta (open innovation), possui foco incorporar, compartilhar e demandar projetos com outras empresas, centro...

Research on the habitats protected by European Union's Habitats Directive (HD) has increased rapidly since its adoption in 1992. However, methods and tools used to assess their conservation status are varied. In this context, we reviewed summarized scientific literature related coastal Natura 2000 list sort parameters map status. We found 225 papers that specifically focused assessment of habit...

Forage is one of the main products of rangeland ecosystems, which is threatened by different anthropogenic disturbances. This study was conducted to assess the impact of urbanization, rural development, agriculture extension, road construction and industry on forage production in an arid and semiarid rangeland using InVEST habitat quality model in spring 2018. In 14 rangeland types, thirty 2×1m...

Geographic assessments of coral diseases are needed to understand their local and geographic spatial-temporal variability. Coral and octocoral diseases and their prevalence were assessed along 4 permanent 10 x 2 m band-transects in each of 3 depth habitats (<4, 5-12 and >15 m) in each of 2 reefs in each of 6 countries across the wider Caribbean during the summer and fall of 2005. A permutationa...

The hypothesis that Euroamerican settlement displaced some populations of large mammal taxa from lowland plains habitats to previously unoccupied highland mountain habitats was commonly believed in the late nineteenth and early twentieth centuries. By the middle twentieth century biologists had come to favor the hypothesis that Euroamerican colonization resulted in the extirpation of population...

This study quantified and compared hypoxia tolerance and swim performance among cyprinid fish species from rapid-, slow- and intermediate-flow habitats (four species per habitat) in China. In addition, we explored the effects of short-term acclimation on swim performance, maximum metabolic rate (M(O2,max)) and gill remodelling to detect habitat-associated patterns of plastic response to hypoxia...

The Gulf Coast contains some of the most important shorebird habitats in North America. This area encompasses a diverse mixture of estuarine and barrier island habitats with varying amounts of freshwater swamps and marshes, bottomland hardwood forests, and coastal prairie that has been largely altered for rice and crawfish production, temporary ponds, and river floodplain habitat. For the purpo...

We present a model for estimating a probabilistic map of ecological habitats using species presence/absence data and environmental covariate data observed at the sites where species presence data were collected. The model is notable because it treats spatially varying patterns of species distributions as the principle defining characteristic of habitats. The model also permits inference about t...

1. Although theory predicts a positive relationship between oviposition preferences and the developmental performance of offspring, the strength of this relationship may depend not only on breeding site quality, but also on the complex interactions between environmental heterogeneity and density-dependent processes. Environmental heterogeneity may not only alter the strength of density dependen...

As environmental sounds are used by larval fish and crustaceans to locate and orientate towards habitat during settlement, variations in the acoustic signature produced by habitats could provide valuable information about habitat quality, helping larvae to differentiate between potential settlement sites. However, very little is known about how acoustic signatures differ between proximate habit...
