Long-term decline of a winter-resident bird community in Puerto Rico

Creator:: Faaborg, John, Arendt, Wayne J., Toms, Judith D., Dugger, Katie M., Cox, W. Andrew, and Mora, Miguel Canals
Abstract:: Despite concern expressed two decades ago, there has been little recent discussion about continuing declines of migrant bird populations. Monitoring efforts have been focused almost exclusively on the breeding grounds. We describe the long-term decline of a winter-resident bird population in Guánica Commonwealth Forest, Puerto Rico, one of the last...

Composition and provenance of terrigenous organic matter transported along submarine canyons in the Gulf of Lion (NW Mediterranean Sea)

Creator:: Pasqual, Catalina, Goñi, Miguel A., Tesi, Tommaso, Sanchez-Vidal, Anna, Calafat, Antoni, and Canals, Miguel
Abstract:: Previous projects in the Gulf of Lion have investigated the path of terrigenous material in the Rhone deltaic system, the continental shelf and the nearby canyon heads. This study focuses on the slope region of the Gulf of Lion to further describe particulate exchanges with ocean’s interior through submarine canyons....

Effects of inoculations with pathogenic and beneficial microorganisms and ammonium of nitrate fertilization on Easter lily growth

Creator:: Valenciano Mora, Jose Roberto
Abstract:: Although chemical fungicides are commonly used to control fungal soil-borne diseases of Easter lilies, Lilium longiflorum Thunb., in field production and greenhouse forcing, cultural and biological controls may be alternatives or complementary to chemicals for control of pathogens. The influence of inoculations with beneficial, symbiotic, and biocontrol microorganisms to enhance...

Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

Creator:: Cifuentes Jara, Miguel
Abstract:: Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

Creator:: Barajas, Miguel F.
Abstract:: Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...

Reexposure and advection of 14C‐depleted organic carbon from old deposits at the upper continental slope

Creator:: Tesi, Tommaso, Goñi, Miguel A., Langone, Leonardo, Puig, Pere, Canals, Miquel, Nittrouer, Charles A., Durrieu de Madron, Xavier, Calafat, Antoni, Palanques, Albert, Heussner, Serge, Davies, Marueen H., Drexler, Tina M., Fabres, Joan, and Miserocchi, Stefano
Abstract:: Outcrops of old strata at the shelf edge resulting from erosive gravity‐driven flows have been globally described on continental margins. The reexposure of old strata allows for the reintroduction of aged organic carbon (OC), sequestered in marine sediments for thousands of years, into the modern carbon cycle. This pool of...

Sea-Salt Impacts On Nutrient Cycling In Oregon Coastal Soils

Creator:: Aleman, Ruben
Abstract:: Sea-salt aerosols (SSA) impact the cycling of nutrients within coastal soils, including the mobility of dissolved organic carbon (DOC) and ammonium, denitrification, and litter decomposition. These aerosols are formed during tumultuous weather in the open ocean and are transported and deposited inland by wind. Soils closer to the ocean are...

Distribution and sources of organic matter in surface marine sediments across the North American Arctic margin

Creator:: Goni, Miguel A., O’Connor, Alison E., Kuzyk, Zou Zou, Yunker, Mark B., Gobeil, Charles, and Macdonald, Robie W.
Abstract:: As part of the International Polar Year research program, we conducted a survey of surface marine sediments from box cores along a section extending from the Bering Sea to Davis Strait via the Canadian Archipelago. We used bulk elemental and isotopic compositions, together with biomarkers and principal components analysis, to...

Experimentation of Synchronous and Variable Speed Small Scale Hydropower Systems

Creator:: Jackson, Elliott C.
Abstract:: Hydropower is the one of the oldest renewable energy technologies and is wrongly thought of today as having little room to grow. The opportunity for new hydropower capacity is immense through both technology advancement and run-of-river new stream reach projects. Despite the age of hydropower, a divide in opinion is...
