Anaerobic degradation of marine algae, seagrass and tropical climbing vines to produce a renewable energy source and the analysis of their anaerobic microbial communities
(2013)
Energy demand by contemporary societies and the excessive consumption of fossil fuels have impulsed research and the employment of renewable energy systems. It has been proposed, in terms of renewable systems, the use of ...
Consequences of invasive grass removal on above and below ground ecosystem dynamics within abandoned agricultural land in the Laguna Cartagena National Wildlife Refuge, Puerto Rico
(2014)
In the tropics, abandoned pasturelands often remain in an arrested state of succession due to non-native grass invasions. Initial restoration approaches often focus on the direct removal of these species. To test if invasive ...
