TLDR
The preponderance of spatial variation in species abundances combined with minimal temporal variation suggests temporal consistency of species abundance throughout the year, and the highly dynamic hydrologic regime may not be a disturbance for Sister Grove Creek fishes.Abstract:
-Fish were sampled monthly at seven sites for 1 yr in Sister Grove Creek, an intermittent prairie stream in N-central Texas. Despite drastic seasonal fluctuations in discharge, abundance of individual species varied more spatially among sites than temporally at individual sites. Spatial differences in assemblage structure were attributed to differences in habitat and to migration from a downstream reservoir. The preponderance of spatial variation in species abundances combined with minimal temporal variation suggests: (1) temporal consistency of species abundance throughout the year, and (2) the highly dynamic hydrologic regime may not be a disturbance for Sister Grove Creek fishes.read more

Modelling stream fish species distribution in a river network: the relative effects of temperature versus physical factors
TL;DR: A dual-approach, quantifying the relative contribution of each environmental factor, appears particularly useful to understand the spatial distribution of stream fish species, which is crucial to accurately predict species distribution modifications in the current context of global change.

Effects of Spates and Drying on Macroinvertebrate Assemblages of an Intermittent and a Perennial Prairie Stream
TL;DR: In this article, the authors compared macroinvertebrate population and assemblage responses to seasonal spates and dewatering in an intermittent and a perennial prairie stream in southern Oklahoma.

Fish community responses to drying disturbances in an intermittent stream: a landscape perspective
TL;DR: An 18-month quantitative electrofishing survey was undertaken on the Selwyn River to determine how the direction and distance to refugia affect the response of fish populations to drying, and how landscape context interacts with flow permanence to produce spatial patterns in communities.

Seasonal and spatial variation in a prairie stream-fish assemblage
Kenneth G. Ostrand,Gene R. Wilde +1 more
TL;DR: In this paper, the authors used stream-fish assemblage and environmental data for 13 sites in the upper Brazos River, Texas, USA during 1997 and 1998 to assess the relationship between environmental conditions, and seasonal and spatial variation in fish species abundance and distribution patterns.

TL;DR: The longitudinal distribution ofSalmo trutta andGalaxias olidus, a small salmoniform fish, was mapped over four summers in the upper reaches of the Lerderderg River, an intermittent stream in central Victoria to suggest a shifting pattern ofS.

Similarity indices, sample size and diversity
TL;DR: It is recommended that the Morisita index be used whenever possible to avoid the complex dealings with effects of sample size and diversity; however, when previous logarithmic transformation of the data is required, theMorisita-Horn or the Renkonen indices are recommended.
