Model Systems of Human Intestinal Flora, to Set Acceptable Daily Intakes of Antimicrobial Residues [PDF]

, 2000
The veterinary use of antimicrobial drugs in food producing animals may result in residues in food, that might modify the consumer gut flora. This review compares three model systems that maintain a complex flora of human origin: (i) human flora ...

Successional Growth Dynamics of Woody Saplings in Tropical Dry Forest Understory

Biotropica, Volume 57, Issue 3, May 2025.
The factors that drive sapling growth in tropical dry forest succession remain unclear. Growth rates are higher in the early stages of succession and then decrease. Light and not water seems to be the main factor limiting sapling growth along succession. The successional guild of species and the taxonomic identity as a Leguminosae were the main factors

Remove saplings early: Cost‐effective strategies to contain tree invasions and prevent their impacts

Journal of Applied Ecology, Volume 62, Issue 3, Page 661-676, March 2025.
Our highest‐ranking strategies represent management actions to start implementing in the field as part of an adaptive management plan that iteratively evaluates the validity of our simulation model and updates the management recommendations. Our study can be applied to guide management of invasive pines and replicated with any invasive woody species ...

Avian seed dispersal out of the forests: A view through the lens of Pleistocene landscapes

Journal of Ecology, Volume 113, Issue 3, Page 510-517, March 2025.
Many European woody species are light‐demanding and fail to regenerate in the shaded interiors of temperate forests. Most of these species are dispersed by frugivorous and seed‐caching birds. The spatial patterns of avian seed dispersal in fragmented anthropogenic landscapes are congruent with an ecological and evolutionary history with open and semi ...

Nitrogen and Phosphorus Allocation Strategies in a Chronosequence of Tropical Dry Forests: Plant Coordination and Environmental Drivers

Biotropica, Volume 57, Issue 2, March 2025.
We explored the allocation strategies of N and P in leaves and fine roots (metabolic organs) and, in stems and coarse roots (woody organs) of nine dominant tree species in secondary tropical dry forests using scaling analysis. The scaling relationships of P versus N concentrations in non‐leaf organs were isometric across secondary succession and ...
