Seasonal resource selection by blue suckers Cycleptus elongatus

Abstract

Telemetry data were used to quantify seasonal resource selection and rank-preferred habitat types for blue suckers Cycleptus elongatus in the middle Missouri River and its tributaries, Iowa, Nebraska, South Dakota, U.S.A. Habitat diversity required by C. elongatus to complete its annual lifehistory cycle was evident by interseasonal variation in habitat selection. Tributaries and unchannelized portions of the middle Missouri River system were selected during the inferred spawning season (spring), habitats along shorelines in the channelized middle Missouri River were selected for postspawning (summer) and areas of reduced current were generally selected for the period preceding spawning (autumn). This study provides insight into mature C. elongatus behaviour throughout its annual life cycle. Furthermore, these results document the interseasonal variability in habitat selection of C. elongatus and highlight the need for development of habitat selection models for other imperilled fish species in aquatic systems affected by anthropogenic developments.

“…BEND, SCC; Galat et al , ). Our results agree with Neely et al () who found that blue suckers did not use tributaries; however, our model further identified that secondary flowing channels were important to blue suckers whereas non‐flowing channels were not.…”

Our results agree with Neely et al (2010) who found that blue suckers did not use tributaries; however, our model further identified that secondary flowing channels were important to blue suckers whereas non-flowing channels were not. Smallmouth buffalo are found throughout Missouri and Mississippi rivers, primarily, in pools with slower, clearer water (Pflieger, 1997).…”

Scale‐Dependent Seasonal Pool Habitat Use by Sympatric Wild Brook Trout and Brown Trout Populations

“…Information on trout habitat use could assist future management, conservation, and restoration efforts in several ways (Neely et al 2010). For example, it may aid in the identification of specific habitats that are necessary for completing certain life history requirements (Saiget et al 2007).…”

An accuracy assessment of ultrasonic transmitter locations determined by mobile telemetry in aquatic systems

“…When the GPSderived accuracy estimates were compared with the measured accuracy, an additional mean error of~1.7 m was apparent, but this source of variation was not statistically significant. Because GPS-derived accuracy was not different than measured accuracy, the use of GPS provides a simpler alternative to quantify accuracy and probably would not affect accuracy of geographic coordinate locations often collected in telemetry studies (Jordan et al 2006;Neely et al 2010;Trested et al 2011). Use of high precision GPS units, location augmentation techniques (e.g.…”
