Near the end of Notes on the State of Virginia (1785), Thomas Jefferson offers a notably ambivalent assessment of Captain John Smith: “To his efforts principally may be ascribed [the colony's] support against the opposition of natives. He was honest, sensible, and well-informed; but his style is barbarous and uncouth. His history, however, is almost the only source from which we derive any knowledge of the infancy of the state” (177). Such ambivalence registers the degree to which late 18th-century ideologies of civility and refinement mediated historical accounts of Virginia's colonial past,

Balanced harvesting has been proposed as a fisheries management strategy to mitigate the impacts of fisheries removal on ecosystem structure. One definition of balanced harvest is that all species should be harvested in proportion to their annual production. However, most marine ecosystems lack comprehensive production estimates necessary to empirically measure the degree of balance. We developed and tested 2 new methods for estimating fish biomass production at the species level with limited data requirements. Application of our techniques to 4 ecological production units in the northwest Atl

Multiple types of flesh browning can occur as storage disorders in ‘Honeycrisp’ apple (Malus ×domestica Borkh.) fruit. Predicting its occurrence is hindered by differing definitions of the types of browning, incomplete understanding of their etiologies, and difficulty in assessing harvest maturity of ‘Honeycrisp’ fruit. In 2013, of ‘Honeycrisp’ fruit grown, harvested over multiple weeks, and stored in Maine, Minnesota, Ontario, and Quebec, only the Quebec fruit developed diffuse flesh browning. A detailed comparison showed that the Quebec fruit differed in size, but not in other quality attrib

For over 80 years, chlorobenzenes were discharged into the Sebasticook River, Maine, from a woollen mill. Environmental conditions were assessed using invertebrate and bacterial techniques that were applied to river bed sediments at three contaminated and two reference sites. Invertebrate densities and species richness did not differ markedly among the impacted sites, one reference site, and data in the literature from clean waters. Paradoxically, the highest diversity and densities of invertebrates and their eggs occurred at the most contaminated site. Insect representation was low compared w

State-space models explicitly separate uncertainty associated with unobserved, time-varying parameters from that which arises from sampling the population. The statistical aspects of formal state-space models are appealing and these models are becoming more widely used for assessments. However, treating natural mortality as known and constant across ages continues to be common practice. We developed a state-space, age-structured assessment model that allowed different assumptions for natural mortality and the degree of temporal stochasticity in abundance. We fit a suite of models where natural

Postdispersal weed seed predation is a significant source of weed mortality in agroecosystems. The magnitude of seed predation, however, is variable. Understanding the relative importance of factors driving variability in seed predation rates will increase the potential utility of seed predation to farmers. We conducted landscape-scale field experiments to quantify and compare the effects of space, time of sampling, and habitat on weed seed predation. Seed predation assays, with and without vertebrate exclosures, measured seed predation rates at spatially explicit sample sites across 8.5 ha of

Previous studies suggest that L. triangularis negatively affects native linyphiid species, with competition for webs as one mechanism. We documented phenological differences between L. triangularis and three native species that illustrate the potential for the reversal of size-based competitive advantage over the course of the year.
