Tracing Personalized Health Curves during Infections

It is difficult to describe host–microbe interactions in a manner that deals well with both pathogens and mutualists. Perhaps a way can be found using an ecological definition of tolerance, where tolerance is defined as the dose response curve of health versus parasite load. To plot tolerance, individual infections are summarized by reporting the maximum parasite load and the minimum health for a population of infected individuals and the slope of the resulting curve defines the tolerance of the population.

The Resilience of the Taku River Ecosystem to Mining Impacts

The Taku River ecosystem supports a vital fishery to many individuals and user groups. It is a transboundary river, with its headwaters in British Columbia, Canada, and is therefore subject to the Pacific Salmon Treaty. There are a large number of potential mines, both along the Taku River or its tributaries
and their drainage areas. Chieftain Metals Corporation plans to revive the Tulsequah and Big Bull mines. This construction poses risk to the drainage, associated fisheries, and coastal communities of the river.

Effects on Bivalves and Associated Ecology in the Chukchi Sea Due to Changing Sea Ice Conditions

The Arctic Ocean sea ice extent has been rapidly declining since 1979. Positive feedback loops are expected to increase the rate of melting, posing a serious threat to the entire Arctic marine ecosystem. The Arctic Ocean ecosystem, including the Chukchi Sea, is currently benthic dominated, but is expected to become pelagic dominated due to changes in algal and zooplankton dominance.

The Effects of pH on the Abundance of Phytoplankton for Mariculture

Very little research has been done on the effects changing ocean pH has on the food source of shellfish. However, since one of the issues shellfish have with changing ocean pH is that they have less energy to take care of other vital needs like obtaining food, researching how changing ocean pH affects the phytoplankton could be significant.

Independently Evolving Species in Asexual Bdelloid Rotifers

Species are fundamental units of biology, but there remains uncertainty on both the pattern and processes of species existence. Are species real evolutionary entities or convenient figments of taxonomists’ imagination [1–3]? If they exist, what are the main processes causing organisms to diversify [1,4]? Despite considerable debate, surprisingly few studies have formally tested the evolutionary status of species [1,5,6].

Novel Hybrid Polymer Composite

A novel low cost hybrid polymer composite, using coir dust and fly ash particle reinforcements is proposed in this paper. Investigation of the dielectric behavior of this hybrid polymer composite proves its potential as a marketable product.

Offshore Drilling And Potential Impacts On Alaska

The topic of developing oil prospects in Alaska by offshore drilling concerns of damaging the Arctic environment and the marine life in many ways. The consequences of an oil spill are waters off Alaska are not only financial but oceanic. The offshore drilling affects wildlife directly.

Bouncing Back After an Eruption of Makushin Volcano

This paper investigates the possible outcomes of an eruption of Makushin Volcano, specifically depicted in this paper, the impact on the community of Unalaska. It has been determined that the ash from a volcanic eruption would be the most threatening aspect of an eruption of Makushin Volcano.

What Makes a Reach Movement Effortful?

Should I rather bring the groceries from the car trunk to the kitchen in 1 trip or in 2 trips? Even in a seemingly simple decision like this, multiple decision parameters are at odds. When doing a single trip, this bothersome task will certainly be finished more quickly but will require an intense physical effort

Increasing Efficiency of Preclinical Research By Group Sequential Designs

Group sizes in preclinical research are seldom informed by statistical power considerations but rather are chosen on practicability [1, 2]. Typical sample sizes are small, around n = 8 per group (, and are only sufficient to detect relatively large sizes of effects. Consequently, true positives are often missed (false negatives), and many statistically significant findings are due to chance (false positives).
