From an island biogeography perspective, the lungs of children and adults could be considered as small versus large island systems, respectively. As such, theoretical predictions from island biogeography anticipate that smaller islands have lower species richness and greater turnover, whereas larger island...
Today systems ecologists are interacting increasingly with physical and social scientists to study coupled human and natural (socio-ecological, socio-environmental) systems (SES). Our premise is that modellers of SES, regardless of their disciplinary background, in all share common roots in General ...
The socioecological model provides a useful theoretical framework that can help to understand how society, community, and individual level factors affect lifestyles and health outcomes of community residents [26,27]. However, the social-ecological model has also been criticized for lacking an agency d...
To further complicate functional conclusions, the ChrXXI inversion has diverged in opposed directions between lake and stream stickleback in the Lake Constance and the Lake Geneva systems. This unexpected trend is unlikely to arise from drift in the young Geneva system: among the 50 most extreme ...
In this study, we reused the IEMS from the Albemarle-Pamlico watershed to model the CRB. We did not change either the modeling infrastructure (FRAMES v.2, Framework for Risk Assessment in Multimedia Environmental Systems) nor the science models SWAT (Soil Water Assessment Tool), WASP (Water ...
(Baltimore, Chicago, New York City), we use community garden networks as a model system to demonstrate how biophysical and social features of urban landscapes control the pattern and magnitude of ecosystem service flows through these systems. We show that community gardens within a city are ...
To prevent cross contamination, water samplers and filtration systems were washed with sterile water and thoroughly rinsed with the local water at each station before water collection and filtration. Water temperature, salinity, and pH of water samples were measured in situ. Chlorophyll-a, chemical ...
Colonial systems’ impacts at large scales over ~400 years included: the substitution of native flora and fauna with newly imported species (Crosby, 1986); extensive deforestation (Grove, 1995; Tucker, 2000; Williams, 2006); and the replacement of Indigenous land use and food production with ...
Recently, a sublinear population growth model exhibited a form of population self-regulation analogous to the individual ontogenetic model and confirmed the conclusion that diversity begets stability34. Third, the synchrony of high-trophic species decreased and that of low-trophic species increased with ...
