Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils
Advanced Science, EarlyView.We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Advanced Science, EarlyView.Schematic illustration of the Pluronic F127 diacrylate/gelatin methacryloyl/poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)/celastrol hydrogel (FGPC) for localized myocardial ischemia–reperfusion injury treatment. FGPC combines sustained celastrol delivery with PEDOT:PSS‐mediated conductive support to attenuate acute oxidative/inflammatory ...

Seed banks and seed dispersal: important topics in restoration ecology§
Acta Botanica Neerlandica, 1996Restoration ecology deals with the scientific and ecological background of nature management practices aiming at the re-establishment of plant species which have disappeared. As we focus on semi-natural landscapes, these disappearances can be caused by intensification of agricultural practices or cessation of human interference.

Functional Ecology
Abstract The process of seed dispersal that underpins ecosystem maintenance is performed by diverse arrays of fruit‐eating animals. However, seed dispersal studies are primarily focused on a subset of these animal communities that disperse seeds by endozoochory. Stomatochory (seed dispersal in which seeds are carried externally and are not swallowed)

What strategies do plants use in trying to disperse their seeds, so as to colonize distant areas? Is it more advantageous to have tiny seeds as light as a feather, or tough and heavy acorns?

Science, 2006
Weta are giant, flightless grasshoppers that are endemic to New Zealand. In the absence of native mammals, weta are thought to perform similar ecological functions. As such, they might be expected to be important seeds dispersers. However, insects are not known to consume fleshy fruits and to disperse seeds after gut passage.

Seed dispersal by neotropical seed predators
American Journal of Primatology, 1998From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms.

Loss of seed dispersal before the loss of seed dispersers
Biological Conservation, 2016(Uploaded by Plazi for the Bat Literature Project) Cryptic function loss occurs when the ecological function of an animal population is significantly altered as a result of disturbance, even though the species is still present in the ecosystem. We reviewed the evidence for cryptic function loss to be widespread among seed disperser populations that ...
