| inducing whole-assemblage change by experimental manipulation of habitat structure. | 1. habitat structure long has been identified as a primary factor influencing local assemblage composition. most evidence has been in the form of correlations of species occurrence and assemblage composition over a range of habitats, with experimental verification of relationships being relatively uncommon because of the difficulties of enacting precise manipulations of habitat structure. 2. fallen timber (also known as coarse or large woody debris) is one of the few habitat-structural elements ... | 2007 | 17584369 |
| habitat selection and behaviour of a reintroduced passerine: linking experimental restoration, behaviour and habitat ecology. | habitat restoration can play an important role in recovering functioning ecosystems and improving biodiversity. restoration may be particularly important in improving habitat prior to species reintroductions. we reintroduced seven brown treecreeper (climacteris picumnus) social groups into two nature reserves in the australian capital territory in south-eastern australia. this study provided a unique opportunity to understand the interactions between restoration ecology, behavioural ecology and ... | 2013 | 23349923 |
| habitat selection and post-release movement of reintroduced brown treecreeper individuals in restored temperate woodland. | it is essential to choose suitable habitat when reintroducing a species into its former range. habitat quality may influence an individual's dispersal decisions and also ultimately where they choose to settle. we examined whether variation in habitat quality (quantified by the level of ground vegetation cover and the installation of nest boxes) influenced the movement, habitat choice and survival of a reintroduced bird species. we experimentally reintroduced seven social groups (43 individuals) ... | 2012 | 23227192 |
| positive effects of helpers on reproductive success in the brown treecreeper and the general importance of future benefits. | 1. numerous studies of cooperatively breeding species have tested for effects of helpers on reproductive success to evaluate hypotheses for the evolution of cooperation, but relatively few have used experimental or statistical approaches that control for the confounding effects of breeder and territory quality. 2. in the brown treecreeper climacteris picumnus, most helpers are male offspring of the breeding pair that have delayed dispersal. we analysed 5 years of data (97 territory-years) using ... | 2007 | 17714275 |
| integrated models to support multiobjective ecological restoration decisions. | many objectives motivate ecological restoration, including improving vegetation condition, increasing the range and abundance of threatened species, and improving species richness and diversity. although models have been used to examine the outcomes of ecological restoration, few researchers have attempted to develop models to account for multiple, potentially competing objectives. we developed a combined state-and-transition, species-distribution model to predict the effects of restoration acti ... | 2017 | 28339135 |
