A Hypothesis on Suspension Feeding in Early Chelicerates (Offacolidae)
DiversityThe Cambrian–Ordovician Plankton Revolution played a crucial role in the Great Ordovician Biodiversification Event (GOBE) or Ordovician Radiation, as a driver of diversification.

Cambrian suspension-feeding tubicolous hemichordates. [PDF]
BMC Biol, 2016 The combination of a meager fossil record of vermiform enteropneusts and their disparity with the tubicolous pterobranchs renders early hemichordate evolution conjectural. The middle Cambrian Oesia disjuncta from the Burgess Shale has been compared to annelids, tunicates and chaetognaths, but on the basis of abundant new material is now identified as a

Gregarious suspension feeding in a modular Ediacaran organism. [PDF]
Sci Adv, 2019 Simulations show fossil Ernietta (548 Ma ago) lived gregariously to aid feeding, providing one of the oldest examples of commensalism.

The effect of tethering on the clearance rate of suspension-feeding plankton. [PDF]
Proc Natl Acad Sci U S A, 2020 Many planktonic suspension feeders are attached to particles or tethered by gravity when feeding. It is commonly accepted that the feeding flows of tethered suspension feeders are stronger than those of their freely swimming counterparts. However, recent flow simulations indicate the opposite, and the cause of the opposing conclusions is not clear.

A possible case of inverted lifestyle in a new bivalved arthropod from the Burgess Shale [PDF]
Royal Society Open Science, 2019 The origin of the arthropod carapace, an enlargement of cephalic tergites, can be traced back to the Cambrian period. However, its disparity and evolution are still not fully understood.

Cambrian suspension-feeding lobopodians and the early radiation of panarthropods. [PDF]
BMC Evol Biol, 2017 Arthropoda, Tardigrada and Onychophora evolved from lobopodians, a paraphyletic group of disparate Palaeozoic vermiform animals with soft legs. Although the morphological diversity that this group encompasses likely illustrates the importance of niche diversification in the early radiation of panarthropods, the ecology of lobopodians remains poorly ...

Frontiers in Marine Science, 2022 The adhesion between food particles and mucus is a fundamental process in particle sorting in suspension-feeding bivalves that requires specific recognition. Interactions between carbohydrate-binding proteins (lectins) expressed on the feeding organs and

Silymarin accumulation in Silybum marianum suspension culture via precursor feeding [PDF]
Catrina: The International Journal of Environmental Sciences, 2021 Silymarin and phenolic compounds have great pharmaceutical applications, particularly as hepatoprotective agents. Silymarin content in Silybum marianum wild populations is low with significant differences between the individuals and the areas of these ...

Frontiers in Ecology and Evolution, 2023 IntroductionThe Early Ordovician Fezouata Shale Formation (485–475Ma, Morocco) is a critical source of evidence for the unfolding Great Ordovician Biodiversification Event (GOBE), the largest radiation in animal diversity during the Paleozoic.

Compounded Apixaban Suspensions for Enteral Feeding Tubes [PDF]
Hospital Pharmacy, 2017 Objective: There is limited information on compounded apixaban formulations for administration via enteral feeding tubes. This study was designed to identify a suitable apixaban suspension formulation that is easy to prepare in a pharmacy setting, is compatible with commonly used feeding tubes, and has a beyond-use date of 7 days.
