Video survey techniques are now commonly used to estimate animal abundance under the assumption that estimates relate to true abundance, a key property needed to make video a valid survey tool. Using the spiny lobster Palinurus elephas as our model organism, we evaluate the effectiveness of baited underwater video (BUV) for estimating abundance in areas with widely different population density....

Abstract Body size influences the effect of individuals and assemblages on ecosystem functioning defines how they respond to changes. We evaluated body structure fish functional groups human modifications at catchment, riparian local scales in 40 streams Pampa grasslands, southern Brazil. To describe structure, we calculated mean, coefficient variation, skewness, kurtosis, using individual biom...

Microarrays have become a routine tool for biomedical research. Data quality assessment is an essential part of the analysis, but it is still not easy to perform objectively or in an automated manner, and as a result it is often neglected. Here, we compared two strategies of array-level quality control using five publicly available microarray experiments: outlier removal and array weights. We a...

It is the position of American Association of Diabetes Educators (AADE) that all inpatient interdisciplinary teams include a diabetes educator to lead or support improvement efforts that affect patients hospitalized with diabetes or hyperglycemia. This not only encompasses patient and family education but education of interdisciplinary team members and achievement of diabetes-related organizati...

In overlay networks, both local and long-distance links appear as a single hop to a routing protocol. Traditional routing metrics (based on hop count or packet loss) fail to take the differences between such links into account. In this paper, we study a metric based on packet delay that has been designed to improve routing in overlay networks. We show a lightweight technique for measuring delay...
