Plastic pollution is killing marine megafauna, but how do we prioritize policies to reduce mortality?

open access: yesConservation Letters, 2021
Pollution by plastic and other debris is a problem affecting the world's oceans and is increasing through time. The problem is so large that prioritizing solutions to effect meaningful change may seem overwhelming to the public and policy makers.

Aerial Drone Surveys Reveal the Efficacy of a Protected Area Network for Marine Megafauna and the Value of Sea Turtles as Umbrella Species

open access: yesDrones, 2022
Quantifying the capacity of protected area networks to shield multiple marine megafauna with diverse life histories is complicated, as many species are wide-ranging, requiring varied monitoring approaches.

The making of novel ecosystems: A process‐based framework for measurement, analysis and application

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

A Comprehensive Survey of Pelagic Megafauna: Their Distribution, Densities, and Taxonomic Richness in the Tropical Southwest Indian Ocean

open access: yesFrontiers in Marine Science, 2017
The distribution and density of pelagic megafauna (marine mammals, seabirds, elasmobranches, and sea turtles) are important indicators of marine biodiversity, reflecting the condition of the underlying ecosystems.

Enter the Anthropocene : an epoch of time characterised by humans [PDF]

open access: yes, 2009
In the first years of the 21st century Earth was being influenced by forces greater than our own and yet as vulnerable. With infinite complacency men and women went to and fro over this globe about their affairs, serene in their assurance of their ...

Anthropogenic seed dispersal: rethinking the origins of plant domestication

open access: yes, 2020
It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as

Challenges of Monitoring Endangered Bryde's Whales During a Period of Rapid Environmental Change

open access: yesAnimal Conservation, EarlyView.
Estimating population size is challenging for rare and elusive species that occur at low densities and are difficult to detect during sampling. We estimated the abundance of a Nationally critical whale species—Aotearoa New Zealand Bryde's whales—using a custom‐formulated POPAN model which incorporated transience to account for their complex residency ...

Traits Shared by Marine Megafauna and Their Relationships With Ecosystem Functions and Services

open access: yesFrontiers in Marine Science, 2019
Traditional ecological research has focused on taxonomic units to better understand the role of organisms in marine ecosystems. This approach has significantly contributed to our understanding of how species interact with each other and with the physical

Megafauna in Salt Marshes

open access: yesFrontiers in Marine Science, 2020
Megafauna shape ecosystems globally through trophic interactions, ecology of fear, and ecosystem engineering. Highly productive salt marshes at the interface of terrestrial and marine systems have the potential to support megafauna species, but a recent ...
