Modeling Spatiotemporal Variability Of The Bioclimate Envelope Of Homarus Americanus In The Coastal Waters Of Maine And New Hampshire, Kisei Tananka, Yong Chen
Modeling Spatiotemporal Variability Of The Bioclimate Envelope Of Homarus Americanus In The Coastal Waters Of Maine And New Hampshire, Kisei Tananka, Yong Chen
Publications
A bioclimate envelope model was developed to evaluate the potential impacts of climate variability on American lobster (Homarus americanus). Bioclimate envelopes were defined by season-, sex-, and stage- specific Habitat Suitability Indices (HSI) based on (1) bottom temperature, (2) bottom salinity, and (3) depth. The species’ association to each of these three environmental attributes was expressed using Suitability Indices (SIs) calibrated by standardized lobster abundance derived from 14 years of fishery independent survey. A regional ocean model (Finite-Volume Community Ocean Model) was integrated with the HSI to hindcast spatiotemporal variability of bioclimate envelopes for American lobster in coastal waters of …
Wintertime Weather-Climate Variability And Its Links To Early Spring Ice-Out In Maine Lakes, Mussie Beyene, Shaleen Jain
Wintertime Weather-Climate Variability And Its Links To Early Spring Ice-Out In Maine Lakes, Mussie Beyene, Shaleen Jain
Publications
In recent decades, Maine lakes have recorded their earliest ice-out dates in over a century. In temperate regions, seasonal lake ice-cover is a critical phenomenon linking climate, aquatic ecosystem and society. And the lengthening of the ice-free period due to warmer climate has been linked to increased algal growth and declining lake water quality, warming of water temperatures leading to alterations in aquatic biodiversity, and the shortening of ice-fishing period and other traditional winter activities over lakes. In this study, historical record of eight lakes and six benchmarked meteorological stations in Maine for the period 1950–2010 were analyzed to (1) …
Nonstationarity In Seasonality Of Extreme Precipitation: A Nonparametric Circular Statistical Approach And Its Application., Nirajan Dhakal, Shaleen Jain, Alexander Gray, Michael Dandy, Esperanza Stancioff
Nonstationarity In Seasonality Of Extreme Precipitation: A Nonparametric Circular Statistical Approach And Its Application., Nirajan Dhakal, Shaleen Jain, Alexander Gray, Michael Dandy, Esperanza Stancioff
Publications
Changes in seasonality of extreme storms have important implications for public safety, storm water infrastructure, and, in general, adaptation strategies in a changing climate. While past research on this topic offers some approaches to characterize seasonality, the methods are somewhat limited in their ability to discern the diversity of distributional types for extreme precipitation dates. Herein, we present a comprehensive approach for assessment of temporal changes in the calendar dates for extreme precipitation within a circular statistics framework which entails: (a) three measures to summarize circular random variables (traditional approach), (b) four nonparametric statistical tests, and (c) a new nonparametric …
On The Travel Emissions Of Sustainability Science Research, Timothy M. Waring, Mario F. Teisl, Eva Manandhar, Mark Anderson
On The Travel Emissions Of Sustainability Science Research, Timothy M. Waring, Mario F. Teisl, Eva Manandhar, Mark Anderson
Publications
This paper presents data on carbon emissions generated by travel undertaken for a major sustainability science research effort. Previous research has estimated CO2 emissions generated by individual scientists, by entire academic institutions, or by international climate conferences. Here, we sought to investigate the size, distribution and factors affecting the carbon emissions of travel for sustainability research in particular. Reported airline and automobile travel of participants in Maine’s Sustainability Solutions Initiative were used to calculate the carbon dioxide emissions attributable to research-related travel over a three-year period. Carbon emissions varied substantially by researcher and by purpose of travel. Travel for the …

Demographic Amplification Of Climate Change Experienced By The Contiguous United States Population During The 20th Century, Jason Samson, Dominique Berteaux, Brian Mcgill, Murray Humphries
Demographic Amplification Of Climate Change Experienced By The Contiguous United States Population During The 20th Century, Jason Samson, Dominique Berteaux, Brian Mcgill, Murray Humphries
Publications
Better understanding of the changing relationship between human populations and climate is a global research priority. The 20th century in the contiguous United States offers a particularly well-documented example of human demographic expansion during a period of radical socioeconomic and environmental change. One would expect that as human society has been transformed by technology, we would become increasingly decoupled from climate and more dependent on social infrastructure. Here we use spatially-explicit models to evaluate climatic, socio-economic and biophysical correlates of demographic change in the contiguous United States between 1900 and 2000. Climate-correlated variation in population growth has caused the U.S. …

Anticipating the effects of climate change on biodiversity is now critical for managing wild species and ecosystems. Climate change is a global driver and thus affects biodiversity globally. However, land-use planners and natural resource managers need regional or even local predictions. This provides scientists with formidable challenges given the poor documentation of biodiversity and its complex relationships with climate. We are approaching this problem in Quebec, Canada, through the CC-Bio Project (http://cc‑bio.uqar.ca/), using a boundary organization as a catalyst for team work involving climate modelers, biologists, naturalists, and biodiversity managers. In this paper we present the CC-Bio Project and its …
