Initial Limnological Observations At Five Small Lakes In Southern Pacific Costa Rica, Sally P Horn, Erik N. Johanson, Kurt A. Haberyan, Mathew S. Boehm, Jessie L. Johanson, Maureen Sánchez P., Mario Hernández V.

Geography Publications and Other Works

Costa Rica has hundreds of lakes, many of which have never been described or sampled by limnologists. Here we summarize initial observations of five small (0.2–1.7ha) lakes located at low elevation (365–490m) in the cantón of Buenos Aries. We collected basic limnological data and samples during visits in 2013 and 2014, and compiled environmental and archaeological data for their surroundings as a contribution to the documentation of lake diversity in Costa Rica, and to support parallel investigations of indicators of environmental history preserved in the sediments of the lakes. Lagunas Carse, Los Mangos, Danta, and Ojo ...

The Impacts Of Green Spaces On Crime In New York City, Matthew Edward Iannone Jr.

Student Theses 2015-Present

From the early 1960s through the mid-1990s, crime in New York City ran rampant. With a gradually dwindling police during this time, a high unemployment rate, and an rapidly increasing metropolitan population, crime peaked in the early 1990s, with the murder rate hitting a record-high of 2,245 in 1990. When Mayor Rudy Giuliani took office in 1994 and appoint Bill Bratton as the NYPD police commissioner, these rates immediately plunged. Numerous factors may have contributed to this sudden decline in crime: the police force grew significantly through the 1990s, more criminals were placed and held in prison, and the ...

This study considers the various factors that regulate nutrients supply in the Red Sea. Multi-sensor observation and reanalysis datasets are used to examine the relationships among dust deposition, sea surface temperature (SST), and wind speed, as they may contribute to anomalous phytoplankton blooms, through time-series and correlation analyses. A positive correlation was found at 0–3 months lag between chlorophyll-a (Chl-a) anomalies and dust anomalies over the Red Sea regions. Dust deposition process was further examined with dust aerosols’ vertical distribution using satellite lidar data. Conversely, a negative correlation was found at 0–3 months lag between SST ...

Becoming Human In The Land: An Introduction To The Special Issue Of Heritage: Landscapes, Drew Hubbell

Landscapes: the Journal of the International Centre for Landscape and Language

This introduction to the special issue of Landscapes theorizes the questions suggested by the theme, "Landscape: Heritage." Weaving personal narrative with literary criticism, cultural studies, human geography, and ecology, the essay examines the way humans become human by developing complex relationships with landscapes over time. As landscapes contain the physical traces of human habitation and development, certain narratives of human inhabitants are written and memorialized in and by those landscapes. The monumentalization of specific heritages leads to contests between human groups who require certain heritages to be memorialized, but not others. Greater awareness of one's humanity requires recovery of ...

Fisheries’ Property Regimes And Environmental Outcomes: A Realist Synthesis Review, Rebecca J. Mclain, Steven Lawry, Maria Ojanen

Geography Faculty Publications and Presentations

Our paper describes the application of a realist approach to synthesizing evidence from 31 articles examining the environmental outcomes of marine protected areas governed under different types of property regimes. The development of resource tenure interventions that promote sustainable management practices has been challenged by the difficulties of determining how contextual factors affect environmental outcomes given the complexity of socio-ecological systems. Realist synthesis is a promising evidence review technique for identifying the mechanisms that influence policy intervention outcomes in complex systems. Through a combination of inductive and deductive analysis of the links between context, mechanisms, and outcomes, realist synthesis can ...

Holocene Dynamics Of Temperate Rainforests In West-Central Patagonia, Virginia Iglesias, Simon G. Haberle, Andrés Holz, Cathy Whitlock

Geography Faculty Publications and Presentations

Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition. In this study, we (1) used lithology, pollen, and charcoal data from Mallín Casanova (47°S) to reconstruct the wetland, vegetation, and fire history of west-central Patagonia; and (2) compared the records with independent paleoenvironmental and archeological information to assess the effects of past climate and human activity on ecosystem dynamics. Pollen data indicate that Nothofagus-Pilgerodendronforests were established by 9,000 cal yr BP. Although the biodiversity of the ...

Expansion Of Major Urban Areas In The Us Great Plains From 2000 To 2009 Using Satellite Scatterometer Data, Lan H. Nguyen, Son V. Nghiem, Geoffrey M. Henebry

GSCE Faculty Publications

A consistent dataset delineating and characterizing changes in urban environments will be valuable for socioeconomic and environmental research and for sustainable urban development. Remotely sensed data have been long used to map urban extent and infrastructure at various spatial and spectral resolutions. Although many datasets and approaches have been tried, there is not yet a universal way to map urban extents across the world. Here we combined a microwave scatterometer (QuikSCAT) dataset at ~1 km posting with percent impervious surface area (%ISA) data from the National Land Cover Dataset (NLCD) that was generated from Landsat data, and ambient population data ...

Data: Pre-Fire Disturbance History Modulates Relationships Between Ground Cover And Post-Fire Conifer Regeneration, Nathan Gill, Dan Jarvis, Tom Veblen, John Rogan, Dominik Kulakowski

Student Works

Understory vegetation and ground cover drive many important ecosystem processes, including tree seedling regeneration. The exact effect of ground cover on tree seedling establishment, survival, and growth depends on biophysical context. In subalpine forests, this context is largely determined by disturbances such as beetle outbreak, blowdown, and fire. Compounded disturbances that overlap in short succession can alter stand properties and trajectories in ways that are not predictable from the additive impact of individual disturbances. The aim of this study is to examine how compounded Dendroctonus rufipennis (spruce beetle; SB) outbreak followed by fire and compounded wind blowdown followed by fire ...
