Enso Controls Interannual Fire Activity In Southeast Australia, Michela Mariani, Michael-Shawn Fletcher, Andrés Holz, Petter Nyman

Geography Faculty Publications and Presentations

El Niño–Southern Oscillation (ENSO) is the main mode controlling the variability in the ocean-atmosphere system in the South Pacific. While the ENSO influence on rainfall regimes in the South Pacific is well documented, its role in driving spatiotemporal trends in fire activity in this region has not been rigorously investigated. This is particularly the case for the highly flammable and densely populated southeast Australian sector, where ENSO is a major control over climatic variability. Here we conduct the first region-wide analysis of how ENSO controls fire activity in southeast Australia. We identify a significant relationship between ENSO and both fire …

The Effects Of Sub-Lethal Predation On The Reproductive Output Of Acanthaster Planci (Crown-Of-Thorns Starfish), Emily Mucha

Independent Study Project (ISP) Collection

Wide-scale declines in live coral cover have been observed throughout history. Modern day coral populations face a multitude of environmental disturbances, however one of the most devastating to the reefs in the Indo-Pacific is the crown-of-thorns starfish (Acanthaster planci), which feeds on the tissues of live corals. The rate at which these individuals feed combined with the explosion of populations in times of outbreak have been seen to exert some of the biggest pressures on coral reefs to date. Following recent episodes of crown-of-thorns starfish (COTS) outbreaks, research on the organism has become increasingly prevalent on the scientific …

Failure To Communicate: Inefficiencies In Voluntary Incentive Programs For Private Forest Owners In Michigan, Mark. D. Rouleau, Jennifer F. Lind-Riehl, Miranda N. Smith, Audrey L. Mayer

College of Forest Resources and Environmental Science Publications

Coordinating forest management across thousands of nonindustrial private forest (NIPF) owners is a difficult yet necessary task for state land management agencies. Voluntary Incentive Programs (VIPs) can coordinate the decentralized activities of these owners in return for services or financial incentives. However, many VIPs typically have low enrollment. Our study investigates the implementation of VIPs to increase forest management coordination among NIPFs in Michigan. We present findings from 20 semi-structured interviews with leaders of state and local land management organizations, and government officials at state natural resource agencies, and contrast their answers with those recorded from 37 interviews of NIPF …

Conflict Of Interest In Exploitation And Utilisation Of Transboundary Natural Resources On Lake Victoria, Edmond M. Were

Journal of African Conflicts and Peace Studies

The management of Lake Victoria as a “regional common” is expected to adhere to the global principles of transboundary natural resource management. However, national interest and power asymmetry amongst riparian states buoyed by external demand have overwhelmed global and regional norms leading to incessant exploitation of the common resources. This paper uses idealist and realist perspectives of power relations to inform the analysis of conflicting interests in transboundary natural resource exploitation. It partly relies on 2012-2013 primary data from purposively selected Beach Management Units in Kenya and Uganda and secondary data from regional fisheries institutions. Notwithstanding the normative value of …

Removal Of Copper (Ii) From Aqueous Solutions Using Cuttlebone As Bio-Adsorbent, Pathompong Vibhatabandhu, Sarawut Srithongouthai

Applied Environmental Research

Biosorptionis an effective process for removal and recovery of heavy metal ions from aqueous solutions. In the present study, batch adsorption experiments were carried out for the removal of copper (Cu II) from aqueous solutions using cuttlebone powder (<100 µm)as a bio-adsorbent. The effects of initial pH, adsorbent dosage, initial concentration, and contact time on adsorption efficiency and capacity were studied to evaluate the optimum conditions for copper removal.The results found optimal conditions at initial pH of 5.0, 10 g L-1cuttlebone, 500 mg L-1initial concentration of Cu II in solution, and 150 min of equilibrium time.The Langmuir isotherm and pseudo-second order kinetic model were fitted to the experimental adsorption data. The maxi-mum adsorption capacity calculated from theLangmuir isotherm was 54.05 mg g-1. This result shows that cuttlebone is an effective bio-adsorbent, constituting a promising, efficient, low-cost, and eco-friendly technology bio-sorbent for reducing copper pollution during wastewater treatment.
