Coffee Hour with Gian Rocco
Of Timber Rattlesnakes, Red Beds, and Groundwater: in Pursuit of the “Holy Grail”
Biologists are known to spend inordinate amounts of time and resources seeking the animals they study. The endeavor becomes even more burdening when rare, imperiled or elusive species are targeted. An understanding of “where to look” is a critical first step in facilitating wildlife study and by extension, the protection of the targeted species or the specific environment critical to its survival. Snakes rarely come to mind when “species protection” is mentioned as no other vertebrate group is as feared, loathed or misunderstood.

“Landscape trap”: Severe fires turning forest to shrubland in California
Large tracts of forest in California are being destroyed by severe fires and some may struggle to recover, instead being replaced by dense shrubland, according to researchers.

A new study found that large, intense burns brought on by fire suppression, drought and other factors may result in historically forested areas of the state changing to shrubland. The shrubs are adept at growing after burns and can keep a hold on these large areas long term, even permanently.

Fulbright Features: Scholar getting firsthand knowledge of refugee research
[Editor’s note: Marina Burka is spending the 2015–16 academic year in Glasgow, Scotland, as a Fulbright Scholar pursuing a master’s degree in human geography and volunteering with an activist organization that supports asylum-seekers and migrants in Scotland.]
On my flight to Rome for the Easter holiday this year, I woke with my head pressed against the window and opened my eyes to an aerial view of the Mediterranean Sea. Even from 36,000 feet above sea level, I could see the white caps of waves far below, all the indication I needed that these were rough waters.

Integrating social network data into GISystems
By Clio Andris
In International Journal of Geographical Information Science
doi: 10.1080/13658816.2016.1153103
Today, online social media outlets provide new and plentiful sources of data on social networks (SNs) and location-based social networks (LBSNs), i.e., geolocated evidence of connections between individuals. While SNs have been used to show how the magnitude of social connectivity decreases with distance, there are few examples of how to include SNs as layers in a GISystem. If SNs, and thus, interpersonal relationships, could be analyzed in a geographic information system (GIS) setting, we could better model how humans socialize, share information, and form social groups within the complex geographic landscape.

Burstiness parameter for finite event sequences
By Eun-Kyeong Kim, Hang-Hyun Jo
In arXiv:1604.01125v1 [physics.soc-ph]
Characterizing inhomogeneous temporal patterns in natural and social phenomena is important to understand underlying mechanisms behind such complex systems, hence even to predict and control them. Temporal inhomogeneities in event sequences have been described in terms of bursts that are rapidly occurring events in short time periods alternating with long inactive periods.

Optimal bidding in a Day-Ahead energy market for Micro Grid under uncertainty in renewable energy production
By Gabriella Ferruzzi, Guido Cervone, Luca Delle Monache, Giorgio Graditi, Francesca Jacobone
In Energy
doi:10.1016/j.energy.2016.02.166
In this paper, a decision making model to formulate the optimal bidding in the Day-Ahead energy market and to evaluate the risk management for a LV grid-connected residential MG, taking into account the uncertainty of renewable power production, i.e., PV (photovoltaic), is proposed. Several investigators have analyzed the role played by MGs into the deregulated electricity market, their contribution to energy price reduction and to the reliability system increase, as well as their impact on the best strategy devising to minimize operating costs.
