Eradication of invasive mammals on islands inhabited by humans and domestic animals

Non-native invasive mammal species have caused major ecological change on many islands. To conserve native species diversity, invasive mammals have been eradicated from several islands not inhabited...

Estimating population size of a nocturnal burrow-nesting seabird using acoustic monitoring and habitat mapping

Population size assessments for nocturnal burrow-nesting seabirds are logistically challenging because these species are active in colonies only during darkness and often nest on remote islands where ...

Divergent foraging strategies during incubation of an unusually wide-ranging seabird, the Murphy’s petrel

Divergent foraging strategies may emerge within a population due to a combination of physiological and environmental factors; yet to persist, neither strategy should offer a consistent selective advantage over the alternative in the long term. Murphy’s petrels...

Density of three skink species on a sub-tropical Pacific Island estimated with hierarchical distance sampling

 

Henderson Island, an island in the United Kingdom Overseas Territory of the Pitcairn Islands, is an uninhabited oceanic raised coral atoll with four endemic land birds, nine endemic flowering plants, and at least 18 endemic invertebrate species (Graves 1992; Benton 1995; Benton and Lehtinen 1995; Florence et al. 1995). Despite a wealth of knowledge about most native biodiversity, very little is known about the reptile species that are present on the island. Because previous reptile surveys on Henderson Island...

Use of Machine Learning (ML) for Predicting and Analyzing Ecological and 'Presence Only' Data: An Overview of Applications and a Good Outlook

Machine learning (ML) has been established and used in science-based applications since the 1970s. The advent and maturation of mathematical algorithms and concepts like Neural Networks, Entropy, Classification and Regression Trees (CARTs), as well as the enhancement of computational power on personal computers worldwide have allowed for the development of many new applications

Studying the demographic drivers of an increasing Imperial Eagle population to inform conservation management

Assessing whether conservation management actions are effective requires a good understanding of the demographic parameters that contribute to the population growth rate. Among the key demographic parameters influencing a population...

Temporary captive population and rapid population recovery of an endemic flightless rail after a rodent eradication operation using aerially distributed poison bait

Operations to eradicate non-native invasive predators from islands generally have large conservation benefits, but may put native species at risk where poison bait is used for eradication. Whether the risk of unintentionally poisoning native...

Spatial scales of marine conservation management for breeding seabirds

Knowing the spatial scales at which effective management can be implemented is fundamental for conservation planning. This is especially important for mobile species, which can be exposed to threats across large areas, but the space use requirements...
