Connectivity of Striped Marlin From the Central North Pacific Ocean

Frontiers in Marine Science, 2022
Striped marlin, Kajikia audax, have been in overfished condition in the Western and Central North Pacific, and overfishing is still occurring, prompting an urgent need to devise conservation and management measures based on the best, current information ...

Integrating multiple technologies to understand the foraging behaviour of Hawaiian monk seals [PDF]

Royal Society Open Science, 2017
The objective of this research was to investigate and describe the foraging behaviour of monk seals in the main Hawaiian Islands. Specifically, our goal was to identify a metric to classify foraging behaviour from telemetry instruments.

Phylogeny of Hawaiian Melicope (Rutaceae): RAD-seq Resolves Species Relationships and Reveals Ancient Introgression

Frontiers in Plant Science, 2019
Hawaiian Melicope are one of the major adaptive radiations of the Hawaiian Islands comprising 54 endemic species. The lineage is monophyletic with an estimated crown age predating the rise of the current high islands.

An Assessment of Mobile Predator Populations along Shallow and Mesophotic Depth Gradients in the Hawaiian Archipelago

Scientific Reports, 2017
Large-bodied coral reef roving predators (sharks, jacks, snappers) are largely considered to be depleted around human population centers. In the Hawaiian Archipelago, supporting evidence is primarily derived from underwater visual censuses in shallow ...

Rapid forest carbon assessments of oceanic islands: a case study of the Hawaiian archipelago

Carbon Balance and Management, 2016
Background Spatially explicit forest carbon (C) monitoring aids conservation and climate change mitigation efforts, yet few approaches have been developed specifically for the highly heterogeneous landscapes of oceanic island chains that continue to ...
