“…By spring 2007, dissolved oxygen levels returned to pre-Katrina levels, and the abundance of longear sunfish had markedly increased. This species was the most abundant upstream fish species prior to Hurricane Katrina, and it is known for its ability to reestablish in habitats after being displaced Gunning and Berra 1969;Berra and Gunning 1970). A similar longitudinal recovery was observed with stream biota exposed to low dissolved oxygen caused by sewage discharge (Hynes 1960).…”

Hurricane Katrina struck southeastern Louisiana on 29 August 2005 and thereby created an opportunity to examine the effects of a catastrophic storm on fish assemblages in a coastal stream. Bayou Lacombe is a small (46.1 river kilometers), primarily freshwater stream that drains into the northeastern portion of Lake Pontchartrain, a large oligohaline estuary located north of New Orleans. In summer 2005 (prior to the hurricane), three upstream and three downstream reaches of Bayou Lacombe were surveyed by electrofishing. These same six reaches were resurveyed in the summer of 2006 to assess the effects of the hurricane on fish assemblages. There were significant changes in fish assemblages at the downstream and upstream reaches. At the downstream reaches, centrarchid species such as bluegill Lepomis macrochirus, warmouth L. gulosus, and redspotted sunfish L. miniatus increased in abundance after the hurricane, as did inland silverside Menidia beryllina and striped mullet Mugil cephalus, both estuarine‐dependent species. At the upstream reaches, longear sunfish L. megalotis decreased after the hurricane and weed shiners Notropis texanus, goldstriped darters Etheostoma parvipinne, and warmouth were absent from posthurricane samples. Principal components and BEST analyses showed that differences in dissolved oxygen between years were related to fish assemblage changes in the upstream reaches. Salinity and temperature were associated with fish assemblage changes in the downstream reaches. Similar significant changes could occur in other coastal streams prone to increased hurricane activity.

ABSTRACT/To evaluate the relative effect of autecologic factors, site-specific factors, disturbance characteristics, and community structure on the recovery of temperate-stream fish communities, we reviewed case histories for 49 sites and recorded data on 411 recovery end points. Most data were derived from studies of low-gradient third-or fourth-order temperate streams located in forested or agricultural watersheds. Species composition, species richness, and total density all recovered within one year for over 70% ot systems studied. Lotic fish communities were not resilient to press disturbances (e.g., mining, logging, channelization) in the absence of mitigation efforts (recovery time >5 to >52 yr) and in these cases recovery was limited by habitat quality. Following pulse disturbances, autecological factors, site-specific factors, and disturbance-specific factors all affected rates of recovery. Centrarchids and minnows were most resilient to disturbance, while salmonid populations were least resilient of all families considered. Species within rock-substrate/nest-spawning guilds required significantly longer time periods to either recolonize or reestablish predisturbance population densities than did species within other reproductive guilds. Recovery was enhanced by the presence of refugia but was delayed by barriers to migration, especially when source populations for recolonization were relatively distant. Median population recovery times for systems in which disturbances occurred during or immediately prior to spawning were significantly less than median recovery times for systems in which disturbances occurred immediately after spawning. There was little evidence for the influence of biotic interactions on recovery rates.While studies of the effect of natural and anthropogenie disturbances on fish populations are common, relatively few studies examine the recovery of fish populations and communities (Niemi and others 1990). Data on recovery rates of aquatic communities are necessary not only for establishing exceedance criteria for water quality standards (Platkin 1988), but also for testing current ecological theory (Resh and others 1988, Yount and. Theories concerning the role of biotic versus abiotic control of fish communities (Schoener 1987), the role of succession in streams (Fisher 1983), island biogeugraphy theory (Minshall and others 1983), life history strategies, zoogeographical constraints, the effects of euvironmenud wiriability, and the effect of food web complexity on the stability of fish communities (Horwi~ 1978, DeAngelis and others 1989, Poff and Ward 1990, Reice and others 1990 are all relevant to the study of recovery processes.

“…Gammarus limnaeus recovered in one day in the summer and in four days in the winter. The experiment was repeated in this same stream with similar results and in a second stream with somewhat different results (Gunning and Berra 1969). In a similar experiment, Townsend and Hildrew (1976) investigated the colonization rate of benthic invertebrates as well as the relative contribution of drift and movement along the substrate.…”

We present a narrative account of case studies of the recovery of flowing water systems from disturbance, focusing on the investigators' conclusions about recovery time and the factors contributing to recovery. We restrict our attention to case studies in which the recovery of some biological property of the system has been examined, excluding those that deal only with physical or chemical properties. Although natural processes and rates of recovery are emphasized, studies of reclamation or restoration of damaged eco-systems are included where they contribute to an understanding of recovery processes.For the majority of studies examined, the systems recovered quite rapidly. The most commonly cited reasons for short recovery times were: (1) life history characteristics that allowed rapid recolonization and repopulation of the affected areas, (2) the availability and accessibility of unaffected upstream and downstream areas and internal refugia to serve as sources of organisms for repopulation, (3) the high flushing rates of Iotic systems that allowed them to quickly dilute or replace polluted waters, and (4) the fact that Iotic systems are naturally subjected to a variety of disturbances and the biota have evolved life history characteristics that favor flexibility or adaptability. In general, longer recovery times were observed in disturbances, such as channelization, that resulted in alterations to physical conditions. This review also indicates that much of our knowledge of recovery in Iotic ecosystems is fragmented and uncoordinated. In addition to establishing the bounds of recovery time, our review identifies some research gaps that need to be filled.The relative stability of communities and ecosystems is determined not only by their resistance to disturbance, but also by their rate of recovery from disturbance others 1975, 1983), Disturbance is now recognized as an important area of ecological research (Gerritsen and Patten 1985) because disturbance affects the organization of communities and contributes to ecological and evolutionary processes. Here we present a narrative account of case studies of the recovery of flowing water systems from disturbance, focusing on the investigators' conclusions about recovery time and the factors contributing to recovery. Selected data from these case studies have been codified for statistical analysis, the results of which are presented in a companion paper (Niemi and others 1990).
