Immigration reduces selection in water microbial community assembly

Frontiers in Microbiology
To investigate the influence of immigration on the selection in structuring local water bacterial communities, we conducted a new community assembly experiment using microcosms filled with sterile original water medium under outdoor conditions.

Neutral models of short-term microbiome dynamics with host subpopulation structure and migration limitation

Microbiome, 2018
Background Most empirical studies tend to focus on microbiome dynamics within hosts or microbiome compositional differences between hosts over short periods.

Niche incumbency, dispersal limitation and climate shape geographical distributions in a species-rich island adaptive radiation

, 2012
Aim: To test the role of climate, dispersal limitation and biotic interactions in limiting species' distributions within an island adaptive radiation by integrating species traits, phylogeny and estimates of dispersal cost into climate-based species ...

Seed dispersal, herbivory and recruitment failure of Persoonia elliptica (Proteaceae) in Western Australian Jarrah (Eucalyptus marginata) forest

, 2012
Persoonia elliptica is a resprouting understorey tree species of the jarrah (Eucalyptus marginata) forests of South-Western Australia. All known populations are lacking in seedlings and saplings, resulting in population structures made up solely of ...

Tree migration-rates : narrowing the gap between inferred post-glacial rates and projected rates [PDF]

, 2013
Faster-than-expected post-glacial migration rates of trees have puzzled ecologists for a long time. In Europe, post-glacial migration is assumed to have started from the three southern European peninsulas (southern refugia), where large areas remained ...

Crop size influences pre-dispersal seed predation in the Brazilian Cerrado

Acta Botânica Brasílica, 2017
Many pre-dispersal seed predators are specialized insects that rely on seeds for larval development. These insects may respond to the amount of seeds produced by a plant (i.e.

Cryptic dispersal networks shape biodiversity in an invaded landscape

, 2019
Species interact with the physical world in complex ways, and life-history strategies could cause species to differ in how they experience the connectedness of the same landscape.

The evolution of flower size and flowering behaviour in plants: The role of pollination and pre-dispersal seed predation

, 2008
This thesis describes research into the effects of insect mediated pollination, and pre-dispersal seed predation, in common species of Asteraceae, varying both between and throughout growing seasons, and suggests that these exert selective pressures ...

Uncovering biodiversity deficits: Experimental evidence for dispersal limitation of woody species in Mediterranean forest patches

Deforestation and habitat disturbance are major drivers of local species extinctions within remnant forest patches. In plants, seed dispersal plays a key role in recolonising patches following disturbance.

Solid dispersion: application and limitations

Journal of Drug Delivery and Therapeutics
Solubility and dissolution rate are essential factors in the bioavailability of a drug. The drug must be well-soluble in water to have good bioavailability. Solid dispersion is among the most widely used and effective methods for increasing solubility and releasing inadequately water-soluble medications.
