Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, EarlyView.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Quantifying functionally equivalent species and ecological network dissimilarity with optimal transport distances

Methods in Ecology and Evolution, EarlyView.
Abstract Quantifying the structure and dynamics of species interactions in ecological communities is fundamental to studying ecology and evolution. While there are numerous approaches to analysing ecological networks, there is not yet an approach that can (1) quantify dissimilarity in the global structure of ecological networks that range from ...

Effects of Anthropogenic Introduction of Substrates on Egg Camouflage and Nesting Success in Ground‐Nesting Birds

Animal Conservation, EarlyView.
We show that the introduction of artificial substrates, in this case, dredged materials to act as nesting substrate for ground‐nesting birds, reduced the effectiveness of egg camouflage for Kentish plovers compared to natural substrates. However, nesting success was not impacted, likely because the community of nest predators was diverse and used a ...

Complementarity in alliances: How strategic compatibility and hierarchy promote efficient cooperation in international security

American Journal of Political Science, EarlyView.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Distance Measures for Unweighted Undirected Networks: A Comparison Study

Australian &New Zealand Journal of Statistics, EarlyView.
ABSTRACT Networks are mathematical structures that allow the representation of complex systems by jointly modelling the elements of the system and the relationships that exist among them. To analyse different contexts or systems, methodological tools are necessary to allow for the quantitative estimation of the differences existing between two or more ...

Two‐year outcomes of epicranial focal cortex stimulation in pharmacoresistant focal epilepsy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to report on the long‐term safety and efficacy of epicranial focal cortex stimulation (FCS) using the EASEE device as adjunctive neuromodulatory therapy in improving seizure control in adults with pharmacoresistant epilepsy originating from one predominant epileptogenic zone.
