Here, we report a draft genome sequence of a picorna-like virus associated with brook trout, Salvelinus fontinalis, gill tissue. The draft genome comprises 8,681 nucleotides, excluding the poly(A) tract, and contains two open reading frames. It is most similar to picorna-like viruses that infect invertebrates.

Adaptive radiations are known for rapid morphological and species diversification in response to ecological opportunity, but it remains unclear if distinct mechanisms drive this pattern. Here, we show that rapid rates of morphological diversification are linked to the evolution of novel ecological niches in two independent Cyprinodon radiations nested within a wide-ranging group repeatedly isol...

A survey of trout species was carried out to assess the stocks' quality inhabiting Palena River Basin, one most important rivers for recreational angling in Chilean Patagonia. Six sampling campaigns were over 16 selected stretches river between February 2012 and June 2013. total 912 collected, 57% rainbow (Oncorhynchus mykiss), 33.3% brown (Salmo trutta), 9.6% brook (Salvelinus fontinalis). Als...

At temperate and boreal latitudes, seasonal transitions drive large fluxes in resource availability. For both terrestrial aquatic predators, pulses have the capacity to shape physiological ecological strategies. However, our ability detect seasonally dynamic trophic interactions is limited by logistical difficulty of year-round monitoring. Here, we document a novel, pulse freshwater predator ac...

Brook trout Salvelinus fontinalis have been used worldwide to stock fishless alpine lakes, negatively affecting native biota. Understanding its spatial ecology in invaded ecosystems can provide information to interpret and contrast its ecological impact. We opportunistically used capture points of brook trout gillnetted during an eradication campaign to assess the distribution patterns of four ...

Brook trout (Sahelinus fontinalis Mitchill) with a chronically implanted dorsal aortic cannula were exposed to acidic environments. During exposure, trout developed severe metabolic acidosis as shown by decreases in standard plasma bicarbonate levels as well as negative base excess values. Reduced oxygen consumption seen in acidotic trout resulted from decreased gill oxygen transfer and reduced...

New records of water mites of the genus Monatractides (Acari: Hydrachnidia, Torrenticolidae) from streams in Australia are presented. Four new species are described: Monatractides polypapillatus, M. ironicus, M. harveyi and M. fontinalis. A first description of the female is given for M. australicus (Cook, 1986). A key to the species of Monatractides from Australia is presented.
