Hydrodynamics of microbial filter feeding [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Microbes compose the majority of life in aquatic ecosystems and are crucial to the transfer of energy to higher trophic levels and to global biogeochemical cycles. They have evolved different foraging mechanisms of which our understanding is poor.

The combined effects of filter-feeding bivalves (Cristaria plicata) and submerged macrophytes (Hydrilla verticillate) on phytoplankton assemblages in nutrient-enriched freshwater mesocosms [PDF]

open access: yesFrontiers in Plant Science, 2023
Freshwater ecosystems are threatened by eutrophication, which causes persistent and harmful algal blooms. Filter-feeding bivalve mollusks and submerged macrophytes (SMs) alleviate the eutrophication effects by inhibiting phytoplankton biomass blooms ...

Top‐down effects of filter‐feeding fish and bivalves moderate bottom‐up effects of nutrients on phytoplankton in subtropical shallow lakes: An outdoor mesocosm study [PDF]

open access: yesEcology and Evolution, 2023
Biomanipulation has been widely used in the ecological restoration of eutrophic lakes for decades. However, biomanipulation is prone to failure if external nutrient loads are not reduced.

Earliest filter-feeding pterosaur from the Jurassic of China and ecological evolution of Pterodactyloidea [PDF]

open access: yesRoyal Society Open Science, 2017
Pterosaurs were a unique clade of flying reptiles that were contemporaries of dinosaurs in Mesozoic ecosystems. The Pterodactyloidea as the most species-diverse group of pterosaurs dominated the sky during Cretaceous time, but earlier phases of their ...

An integrated approach to understanding the role of the long neck in plesiosaurs [PDF]

open access: yesActa Palaeontologica Polonica, 2017
The evolution and function of the long neck in plesiosaurs, and how the problems associated with stiffness or flexibility were overcome during feeding, or rapid swimming during predator avoidance, are explored, and a new interpretation for the function ...

A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest [PDF]

open access: yesRoyal Society Open Science, 2015
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen ...

Hydrodynamic analysis of bioinspired vortical cross-step filtration by computational modelling

open access: yesRoyal Society Open Science, 2023
Research on the suspension-feeding apparatus of fishes has led recently to the identification of novel filtration mechanisms involving vortices. Structures inside fish mouths form a series of ‘backward-facing steps' by protruding medially into the mouth ...

Bivalve Feeding on the Brown Tide Aureoumbra lagunensis in a Shallow Coastal Environment

open access: yesFrontiers in Marine Science, 2021
Brown tides formed by Aureoumbra lagunensis decrease light penetration in the water column and are often followed by hypoxic events that result in the loss of fish and shellfish.

Salishicetus meadi, a new aetiocetid from the late Oligocene of Washington State and implications for feeding transitions in early mysticete evolution [PDF]

open access: yesRoyal Society Open Science, 2018
Living baleen whales, or Mysticeti, lack teeth and instead feed using keratinous baleen plates to sieve prey-laden water. This feeding strategy is profoundly different from that of their toothed ancestors, which processed prey using the differentiated ...

Hydrodynamics of sponge pumps and evolution of the sponge body plan

open access: yeseLife, 2020
Sponges are suspension feeders that filter vast amounts of water. Pumping is carried out by flagellated chambers that are connected to an inhalant and exhalant canal system.
