With more than 407 species of freshwater and brackish water fishes, Gabon is a country rich in ichthyological biodiversity, but its aquatic environments remain poorly explored. We present and describe a new species of Enteromius, adding to the 16 species of Enteromius currently recorded from that country. This new species...
Two myxozoan species were observed in the kidney of topsmelt, Atherinops affinis, during a survey of parasites of estuarine fishes in the Carpinteria Salt Marsh Reserve, California. Fish collected on 3 dates in 2012 and 2013 were sectioned and examined histologically. Large extrasporogonic stages occurred in the renal interstitium of...
Surface transient storage (STS) has functional significance in stream ecosystems because it increases solute interaction with sediments. After volume, mean residence time is the most important metric of STS, but it is unclear how this can be measured accurately or related to other timescales and field-measureable parameters. We studied mean...
Since most wolf (Canis lupus) diet studies have been conducted in inland ecosystems, comparatively few data are available on diets of wolves in coastal systems. We investigated the diet of wolves in Glacier Bay, Alaska, from 12 May to 28 June in both 2010 and 2011. Although we identified 12...
The development and widespread implementation of best practices in transportation engineering classrooms is important in attracting and retaining the next generation of transportation engineers. Engineering education professionals have uncovered many best practices in the field; however, the process of effectively disseminating and ultimately achieving the widespread adoption of these best...
Prediction of year-class strength is a critical challenge for fisheries managers. Theoretically,
predictions of recruitment should be better when they are based on estimates of cohort
size taken close to the age of recruitment and may improve if the effects of environmental factors
that influence pre-recruit mortality are accounted for....
dependence and regulation of relatively large local populations? If so, what are the causative mechanisms and their implications? We conducted an eight-year multigeneration study of population dynamics of bicolor damselfish (Stegastes partitus) inhabiting four large coral reefs in the Bahamas. After a four-year baseline period, it was clear that two...
In an enhancement-mode, n-channel (p-channel) oxide thin-film transistor (TFT), current arises as a consequence of electron (hole)
transport within a narrow accumulation layer. The square-law model accurately describes enhancement-mode TFT behavior and
establishes the equations appropriate for carrier mobility extraction. In contrast, in a depletion-mode oxide TFT, carrier transport
can...
Species distribution models (SDMs) are currently being used to identify essential fish habitat and guide
fisheries management worldwide. We present SDMs based on generalized linear mixed models (GLMM) of
the fall distribution or occurrence of juvenile American shad (Alosa sapidissima) and juvenile striped bass
(Morone saxatilis) in the Hudson River...
This paper presents a new Rock Share Estimation (RSE) procedure that can estimate the cost
of forest road construction. One of the key elements of the total cost in road construction is the
cost of embankment. The proportion of the rock directly influences the price of this activity.
Hence, a...
