Decision tools for managing biological invasions: existing biases and future needs

Exploiting Allee effects for managing biological invasions.

Biological invasions are a global and increasing threat to the function and diversity of ecosystems. Allee effects (positive density dependence) have been shown to play an important role in the establishment and spread of non-native species. Although Allee effects can be considered a bane in conservation efforts, they can be a benefit in attempts to manage non-native species. Many biological in...

Managing sparse data in biological invasions: a simulation study

Despite recent progress, estimating species spread and the risk of different sites becoming invaded remains a major challenge in invasion biology. One of the most common problems is sparse data: we will have rarely sampled all areas for invaders and consequently do not know where all the invaded sites are. This is problematic because the entire system of sites determines invasion probability fo...

Problems with Existing Prediction Studies and Future Research Needs

Biological invasions

Where do basal bodies come from? The basal body is considered to be a self-replicating organelle. In a process that is not yet completely understood, the daughter basal body is assembled adjacent and orthogonal to the mother organelle. Although this was long speculated to be a templated assembly process, it is likely that the mother basal body acts as the site where components required for asse...

Managing attention deficit/hyperactivity disorder: unmet needs and future directions.

The management of attention deficit/hyperactivity disorder (ADHD) requires a multimodal approach. Although shared-care protocols are suggested, uptake by general practice has been tentative. Behavioural management, both on its own and in combination with pharmacotherapy, reduces core symptoms and associated behaviours, such as oppositional defiant disorder (ODD). Links with education and social...
