Tropical insular fish assemblages are resilient to flood disturbance

ECOSPHERE, 6(12).

By: W. Smith n & T. Kwak n

author keywords: Agonostomus monticola; amphidromous fishes; assemblage; Caribbean island; community; disturbance; Eleotris perniger; flooding; Gobiomorus dormitor; Sicydium; stochastic processes; tropical stream fishes
TL;DR: The native fish assemblage appeared resilient to flood disturbance, rapidly compensating for mortality and displacement with increased recruitment and recolonization of upstream habitats and rapid recovery processes at the population level appeared to dampen effects at the assemblages level.

By: D. Pender* & T. Kwak*

TL;DR: The fecundity and condition factor of prespawning brown trout were significantly lower at Beaver Tailwater, a reach known for reproductive failure, than at other sites, among which no differences were found. (via Semantic Scholar)

1999 journal article

Modeling the effects of land use and climate change on riverine smallmouth bass

ECOLOGICAL APPLICATIONS, 9(4), 1391–1404.

By: J. Peterson* & T. Kwak n

author keywords: climate change; floodplain; flow regime; global warming; Kankakee River; USA; land use; Micropterus dolomieu; population model; simulation; smallmouth bass; streamflow; watershed restoration
TL;DR: It is suggested that land-use changes may be a greater detriment to riverine fishes than projected climate change and that the combined effects of both factors may lead to local species extinction, but the negative effects of increased temperature and precipitation associated with future global warming could be mitigated by river channel, floodplain, and watershed restoration.

By: T. Kwak* & J. Zedler*

author keywords: food web; restoration; salt marsh; stable isotopes; wetland
TL;DR: The demonstration of a salt marsh–channel linkage in these systems affirms that these habitats should be managed as a single ecosystem and that the restoration of intertidal marshes for endangered birds and other biota is compatible with enhancement of coastal fish populations.

TL;DR: Tournament mortality of the population was minimal relative to other causes of mortality; total tournament mortality estimates for 1992 represented 2.3% of angling mortality and 1.3–3.0% of total mortality in Lake Minnetonka. (via Semantic Scholar)

PRODUCTION DYNAMICS OF SMALLMOUTH BASS IN A SMALL MINNESOTA STREAM

TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY, 122(4), 588–598.

By: T. Waters*, J. Kaehler*, T. Polomis* & T. Kwak*

TL;DR: Annual production by smallmouth bass was much lower than trout production in similarly fertile streams in southern Minnesota and Wisconsin, and more-restrictive creel regulations may be needed for smallmouthbass than for trout, even in streams of similar basic productivity.

author keywords: CATOSTOMIDAE; HYBRIDIZATION; MICROHABITAT; REPRODUCTION; SPECIATION; SUCKERS
TL;DR: It is suggested that differences in spawning habitat, behavior, and morphology act as reproductive isolating mechanisms between the species and that the dichotomy in habitat and behavior may be due to competitive interactions. (via Semantic Scholar)
