“…Substrate composition is thought to be a factor affecting Eastern Sand Darter habitat utilization because of their characteristic burrowing (Drake et al 2008), and our aquarium study supports the observations of others (see Grandmaison et al 2004 * ) that sand darters tend to burrow. Therefore, changes in substrate composition could impact the fish's ability to use certain areas.…”

“…The Eastern Sand Darter may be unable to burrow easily into 244 THE CANADIAN FIELD-NATURALIST Vol. 122 Drake et al (2008) showed that age-0 Eastern Sand Darters grew better in areas with more sand than in areas with more silt, and argued that sand-dominated substrates would be energetically beneficial because of higher oxygen levels and greater prey availability. Some regulations for protecting river water quality, including prevention of excess sediment input, have probably decreased silt loads and improved habitat for the Eastern Sand Darter.…”

“…The burrowing behavior makes the species sensitive to siltation, which can decrease oxygen availability and may affect prey availability. Drake et al (2008) found that growth rates of age-0 Eastern Sand Darter were higher in sand-dominated substrates than in silt-dominated substrates. This sensitivity to clean, sandy substrates makes the Eastern Sand Darter a good indicator of habitat quality.…”

“…Agricultural and industrial pollution, channelization, the creation of impoundments, and land use practices such as removal of riparian vegetation and urban/suburban development which increase erosion and runoff all potentially alter the substrate composition within rivers (Clay 1975;Smith 1979). As a result, formerly sandy areas that had supported sand darters may no longer be suitable, resulting in de clines in local populations (Scott and Crossman 1973;Smith 1985;Daniels 1993;Holm and Mandrak 1996;Grandmaison et al 2004 * ;Drake et. al 2008).…”

The declines in Eastern Sand Darter populations associated with increased sedimentation and other human impacts have resulted in the species being classi fied as globally rare (G3) and receiving protected designa tions in the Canadian provinces of Ontario and Quebec (COSEWIC 2008 * ; Drake et al 2008), and several U.S. states including Vermont, New York, and Mich i gan (Grandmaison et. al 2004 * ).…”

O'Brien, Shannon M., and Douglas E. Facey. 2008. Habitat use by the Eastern Sand Darter, Ammocrypta pellucida, in two Lake Champlain tributaries. Canadian Field-Naturalist 122(3): 239-246.The Eastern Sand Darter (Ammocrypta pellucida) is endangered or threatened throughout much of its range, which includes the St. Lawrence-Lake Ontario drainage of southern Ontario and Quebec and several Vermont tributaries of Lake Champlain. The species is known for its tendency to burrow, and field observations have suggested that habitat use may depend on substrate particle size. To determine whether Eastern Sand Darter densities were correlated with substrate particle size, fish and substrates were sampled in 156 plots in two Vermont rivers during the summers of 2001 and 2002. The Eastern Sand Darter occurred mainly in areas in which substrate composition was over 45% fine to medium sand (0.24-0.54 mm); they were much less abundant in areas in which substrate composition exceeded 25% particles greater than 1.9 mm. Substrate preference was tested by allowing 49 fish kept in aquaria to choose among four different substrates. The fish showed a significant preference (P<0.005) for the finer substrate categories (0.24-0.54 mm, 0.55-1.0 mm), and mostly avoided the coarser substrates (1.0-1.9 mm, 2.0-4.1 mm). This suggests that the Eastern Sand Darter is selective regarding substrate composition, and therefore might be affected by fluctuations or changes in substrate composition within its habitat, such as those caused by changes in flow.

Secondary invasion of the round goby into high diversity Great Lakes tributaries and species at risk hotspots: potential new concerns for endangered freshwater species

et al. 2009

The round goby (Neogobius melanostomus) first invaded North America in 1990 when it was discovered in the St. Clair River. Despite more than 15 years of potential invasion, many Great Lakes' lotic systems remained uninvaded. Recently, we captured the round goby from several Great Lakes tributaries known as species-at-risk hotspots. With a combination of field sampling of round gobies and literature review of the impact of round gobies on native taxa, we assess the potential impacts of the secondary invasion to native species using three mechanisms: competition; predation; and indirect impacts from the loss of obligate mussel hosts. We estimate that 89% (17/19) of benthic fishes and 17% (6/36) of mussels that occur in these systems are either known or suspected to be impacted by the secondary invasion of round goby. In particular, we note that the distribution of potential impacts of round goby invasion was largely associated with species with a conservation designation, including seven endangered species (1 fish, 6 mussels). As these recent captures of round goby represent novel occurrences in high diversity watersheds, understanding the potential impacts of secondary invasion to native biota is fundamental to prevent species declines and to allow early mitigation.
