Quantifying the relative impacts of top‐down vs. bottom‐up control of ecosystems remains a
controversial issue, with debate often focusing on the perennial question of how predators …

Brodifacoum, an anticoagulant used in cereal‐based baits for the control of vertebrate pests,
especially rodents, may be accidentally ingested by non‐target species. In birds, its acute …

Food webs in nature have multiple, reticulate connections between a diversity of consumers
and resources. Such complexity affects web dynamics: it first spreads the direct effects of …

This study quantifies the flow of energy and biomass from a productive marine system to a
relatively unproductive terrestrial system. Biomass from marine food webs (here, the Gulf of …

This paper evaluates the multiple factors that determine the production of plant biomass and
its distribution among producers and various trophic groups of consumers. In rough order of …

1. Introduced predators account for a large part of the extinction of endemic insular species,
which constitutes a major component of the loss of biodiversity among vertebrates …

Some islands in the Gulf of California support very high densities of spiders. Spider density
is negatively correlated with island size; many small islands support 50-200 spiders per m3 …

Evidence from subfossils and from present distributions confirming range contractions and
extinctions of New Zealand amphibians and reptiles is consistent with that from New …

We define an ecosanctuary in a New Zealand context as 'a project larger than 25 ha
implementing multi-species, pest mammal control for ecosystem recovery objectives, and …

This paper summarises evidence for low rates of annual reproductive output (no. of offspring
or eggs/female/yr) in New Zealand reptiles. Tuatara (Sphenodon spp.) and the geckos …
