Seagrass beds are common features of coastal ecosystems worldwide, and their associated infauna are often more productive and diverse than in unvegetated habitats. Little is known, however, about the…
Long-term trends in loblolly pine productivity and stand characteristics in response to thinning and fertilization in the West Gulf region

Accurate and efficient estimation of forest growth and live biomass is a critical element in assessing potential responses to forest management and environmental change. The objective of this study…

This paper presents a probabilistic procedure called least-squares regression (LSR) for estimating the parameters of an equation to represent the relationship between two variables.
Macroinvertebrate diet in intertidal seagrass and sandflat communities: A study using C, N, and S stable isotopes
C, N, and S stable isotopes were used to characterise the diet of the dominant macroinvertebrates found in intertidal Zostera capricorni and sandflat communities of southern New Zealand in late summer and winter to highlight the importance of accounting for spatial and temporal variability in primary producer isotopic signatures.
A multi-method approach for identifying meiofaunal trophic connections
The contribution of primary producers to the diet of meiofauna and to bulk and fine sediment organic matter was investigated in Papanui Inlet, southern New Zealand, using stable isotopes and fatty acid analyses in the field and in a microcosm experiment to circumvent limitations associated with the indi- vidual methods.
Unusually high food availability in Kaikoura Canyon linked to distinct deep-sea nematode community
Unimodal relationship between biomass and species richness of deep-sea nematodes: implications for the link between productivity and diversity
These findings support earlier suggestions of a uni- modal productivitydiversity relationship in the deep sea that were based on other proxies (e.g. water depth, modelled particulate organic carbon flux) and argue that the 'productivity context' is of primary importance when determining the strength and nature of the relationship between other environmental factors and diversity.
