After the Hype: Resilience Seeking in Emerging Technology Ecosystems

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Hype often helps emerging technology ecosystems gain early support for their innovative value propositions, but the initial excitement around the technology typically vanishes at some point. This decrease in excitement and support may lead some ecosystems to fail while others are resilient and recover.

Heat stress induces organelle alterations in Macrocystis pyrifera gametophytes

Journal of Phycology, EarlyView.
Abstract Kelp, brown macroalgae in the order Laminariales, provide ecosystem services vital to ocean biodiversity. However, kelp forests worldwide are declining due to abiotic stressors such as ocean warming. In this study, we present results from high‐resolution confocal microscopy and in vivo imaging system imaging using protocols developed to ...
