Seed mass diversity along resource gradients: the role of allometric growth rate and size-asymmetric competition

open access: yes, 2018
The large variation in seed mass among species inspired a vast array of theoretical and empirical research attempting to explain this variation. So far, seed mass variation was investigated by two classes of studies: one class focuses on species varying ...

Numerical and functional response of phagotrophic aquatic protists: the ideal experiment—and why we cannot get it

open access: yesFrontiers in Microbiology
Protists are paramount for biogeochemical cycling in every aquatic ecosystem due to their vast population sizes and physiological versatility. Numerical response (NR) and functional response (FR) experiments are cornerstones of trait-based functional ...

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]

open access: yes, 2017
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Impacts of farming practice within organic farming systems on below-ground ecology and ecosystem function [PDF]

open access: yes, 2006
Maintaining ecosystem function is a key issue for sustainable farming systems which contribute broadly to global ecosystem health. A focus simply on the diversity of belowground organisms is not sufficient and there is a need to consider the contribution

Predation effects on mean time to extinction under demographic stochasticity

open access: yes, 2012
Methods for predicting the probability and timing of a species' extinction are typically based on a combination of theoretical models and empirical data, and focus on single species population dynamics.
