Estimating macrobenthic secondary production from body weight and biomass: a field test in a non-boreal intertidal habitat [PDF]
Production (P) and biomass (B) data of different species from 3 stations in the intertidal zone of the Ria Formosa (southern Portugal, 37-degrees-N) were analysed.

How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments [PDF]
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources.

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]
Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically

Lack of genetic structure suggests high connectivity of Parnassius phoebus between nearby valleys in the Alps [PDF]
The spatial scale of intraspecific genetic connectivity and population structure are important aspects of conservation genetics. However, for many species these properties are unknown.

Isotopic niche variability in macroconsumers of the East Scotia Ridge (Southern Ocean) hydrothermal vents: What more can we learn from an ellipse? [PDF]
Aspects of between-individual trophic niche width can be explored through the isotopic niche concept. In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex.
