Hatch timing of largemouth bass: implications for recruitment at the Northern edge of their native range

Autor: Giancarlo Coppola, Craig J. Kelling, Daniel J. Dembkowski, Daniel A. Isermann

Publikováno v: Journal of Freshwater Ecology, Vol 39, Iss 1 (2024)

Climate-related shifts in hatch timing could mean that age-0 largemouth bass Micropterus salmoides in north temperate lakes reach larger sizes and experience higher survival, which may contribute to increased prevalence of this species in many lakes.

Linking Pedigree Information to the Gene Expression Phenotype to Understand Differential Family Survival Mechanisms in Highly Fecund Fish: A Case Study in the Larviculture of Pacific Bluefin Tuna

Autor: Motoshige Yasuike, Kazunori Kumon, Yosuke Tanaka, Kenji Saitoh, Takuma Sugaya

Publikováno v: Current Issues in Molecular Biology, Vol 43, Iss 3, Pp 2098-2110 (2021)

Mass spawning in fish culture often brings about a marked variance in family size, which can cause a reduction in effective population sizes in seed production for stock enhancement. This study reports an example of combined pedigree information and

Unbalanced population structure and reliance on intraspecific predation by largemouth bass in an agricultural pond with no available prey fish

Autor: Natsuru Yasuno, Yasufumi Fujimoto, Tetsuo Shimada, Shuichi Shikano, Eisuke Kikuchi

Publikováno v: Journal of Freshwater Ecology, Vol 35, Iss 1, Pp 523-534 (2020)

The carnivorous largemouth bass Micropterus salmoides has been introduced to many regions and poses a threat to native aquatic organisms due to predation, resulting in a significant decrease in biodiversity. Under conditions of prey scarcity, the lar

Influence of intra‐ and interspecific variation in predator–prey body size ratios on trophic interaction strengths

Autor: Ross N. Cuthbert, Ryan J. Wasserman, Tatenda Dalu, Horst Kaiser, Olaf L. F. Weyl, Jaimie T. A. Dick, Arnaud Sentis, Michael W. McCoy, Mhairi E. Alexander

Publikováno v: Ecology and Evolution, Vol 10, Iss 12, Pp 5946-5962 (2020)

Abstract Predation is a pervasive force that structures food webs and directly influences ecosystem functioning. The relative body sizes of predators and prey may be an important determinant of interaction strengths. However, studies quantifying the

Introduced European minnow Phoxinus phoxinus in alpine lakes may increase total mercury concentration in brown trout Salmo trutta

Autor: Reidar Borgstrøm, Sigurd Rognerud, Sondre Meland, Bjørn Olav Rosseland

Publikováno v: Fauna Norvegica, Vol 41 (2021)

In Norway, the cyprinid European minnow Phoxinus phoxinus has been spread far outside its previous natural distribution area, with lots of establishments in mountain lakes where brown trout Salmo trutta originally was the only fish species. We have a

Age-0 walleye Sander vitreus display length-dependent diet shift to piscivory

Autor: Christopher S. Uphoff, Casey W. Schoenebeck, Keith D. Koupal, Kevin L. Pope, W. Wyatt Hoback

Publikováno v: Journal of Freshwater Ecology, Vol 34, Iss 1, Pp 27-36 (2019)

The ontogenetic diet shift to piscivory can be energetically beneficial for fish growth and allows larger, more energetically profitable prey to be consumed. A shift to piscivory may be easier for longer individuals within a cohort due to larger gape

Cormorant abundance, diet, and foraging habits in Arizona

Autor: Larisa E. Harding, Jacob I. Mesler

Publikováno v: Journal of Field Ornithology, Vol 93, Iss 3, p 6 (2022)

In Arizona, USA, Double-crested Cormorants (Nannopterum auritum) primarily overwinter, whereas Neotropic Cormorants (N. brasilianum) are common residents year round. Concern exists that both species are increasing in numbers and may have a negative i
