Crime rates affect everything from home values, to the quality of education. Through the use of Social Disorganization Theory this paper will support the hypothesis that there is a correlation between neighborhood upkeep and crime rates within neighborhoods. Social Disorganization theory itself aims to show the correlation between the place...
Meiotic chromosome counts from 200 populations of Claytonia
(Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based
on three morphologically different, chemically distinct, and geographically
defined diploids. The basic chromosome number is x=6.
Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid
mature basal leaves ranges southeastward from...
Claytonia perfoliata is a west-American polyploid complex of
common annuals (x=6). The species is polymorphic; exomorphic
characters are often variable within local populations. In a transect
of the Columbia River Gorge diploids, tetraploids, hexaploids, octoploids,
and decaploids were collected, which varied in shape of basal
and cauline leaves, degree of...
The field of conservation genetics, when properly implemented, is a constant juggling act integrating molecular genetics, ecology, and demography with applied aspects concerning managing declining species or implementing conservation laws and policies. This young field has grown substantially since the 1980s following the development of polymerase chain reaction and now...
Time can be a limiting constraint for consumers, particularly when resource
phenology mediates foraging opportunity. Though a large body of research has explored
how resource phenology influences trophic interactions, this work has focused on the topics
of trophic mismatch or predator swamping, which typically occur over short periods, at
The traceability practices and systems of 48 separate seafood businesses were assessed as part of an evaluation
of 9 global seafood value chains (from catch to point of sale to the consumer). The purpose was to gain insights and
provide knowledge about the impact of traceability on improving seafood industry...
Native lamprey species in the Central Valley of California serve important ecological roles in rivers and tributaries and face similar conservation challenges as salmonids. Concerns of declining lamprey populations have led to collaboration of tribes, local, state, and federal agencies to increase understanding of ecology and life history. Pacific Lamprey...
High-elevation aquatic ecosystems are highly vulnerable to climate change, yet relatively few records are available to characterize shifts in ecosystem structure or their underlying mechanisms. Using a long-term data set on seven alpine lakes (3126 to 3620 m) in Colorado, USA, we show that ice-off dates have shifted 7 days earlier over...
Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model that represents primary ecohydrological networks to examine how connectivity between ecosystem components impacts...
