Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Natural variability of macro-zooplankton and larval fishes off the Kimberley, north-western Australia: Preliminary findings [PDF]

open access: yes, 2011
During the austral autumn, spatial (regional cross-shelf) and temporal (tidal cycle and spring-neap cycle) variability of macro-zooplankton and larval fishes off the Kimberley coast were examined in conjunction with the physical oceanography.

Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

Cyclonic Mesoscale Eddy Impact on Zooplankton Vertical Migration at Station ALOHA in the Coast of Hawaii

open access: yes, 2021
Light intensity over the course of a day sets the circadian rhythm for the vertical movement of microorganisms across the entire ocean. This research focused on the distribution of zooplankton at station ALOHA off the coast of Hawaii and examines the ...

Species composition, density and biomass of Rotatoria, Protozoa and Meroplanktons in the south of the Caspian Sea (Babolsar) [PDF]

open access: yesبوم‌شناسی آبزیان, 2017
In this study, species composition, density and biomass of zooplanktons including Rotatoria, Protozoa and Meroplanktons were sampled using Juday net with mesh size of 100 µ at depths of 5, 10 and 20 meters in southern Caspian Sea (Babolsar) in two ...

Mesophotic octocoral larval settlement preferences and behaviors

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

Seasonal variation of zooplankton abundance, composition and biomass in the Chabahar Bay, Oman Sea

open access: yesInternational Journal of Aquatic Biology, 2014
Temporal and spatial variation of zooplankton abundance, composition and biomass were examined on the Chabahar Bay, Oman Sea. The Chabahar Bay, a subtropical and semi-enclosed bay, provides an ideal breeding ground for many fish and shellfish.

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Omnivory by planktivores stabilizes plankton dynamics, but may either promote or reduce algal biomass [PDF]

open access: yes, 2010
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by planktivorous fish.
