The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

U.S. Extended Continental Shelf Cruise to Map Gaps in Kela and Karin Ridges, Johnston Atoll, Equatorial Pacific Ocean [PDF]

open access: yes, 2014
The objectives for cruise KM14-17 are to map the bathymetry of two gaps in two submarine ridges in the vicinity of Johnston Atoll. One ridge gap occurs along the informally named Keli Ridge (Hein et al., 2005) south of Johnston Atoll and the other ridge ...

Institutional Entrepreneurship and Work for Enhanced Sustainability at the Base of the Pyramid

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Promoting sustainability at the base of the pyramid (BoP) often falls short of inclusive development due to informal and fragmented institutions, creating institutional voids. Although institutions are critical in BoP settings, there is limited clarity on how institutional mechanisms can address sustainability challenges in low‐income contexts
