So Long and Thanks for All the Fish: Overexploitation of the Regionally Endemic Galapagos Grouper Mycteroperca olfax (Jenyns, 1840)
The regionally endemic Galapagos Grouper, locally known as bacalao, is one of the most highly prized finfish species within the Galapagos Marine Reserve (GMR). Concerns of overfishing, coupled with a lack of fishing regulations aimed at this species raises concerns about the current population health. We assessed changes in population health over a 30-year period using three simple indicators: (1) percentage of fish below reproductive size (Lm); (2) percentage of fish within the optimum length interval (Lopt); and (3) percentage of mega-spawners in the catch. Over the assessed period, none of the indicators reached values associated with healthy populations, with all indicators declining over time. Furthermore, the most recent landings data show that the vast majority of the bacalao caught (95.7%,) were below Lm, the number of fish within the Lopt interval was extremely low (4.7%), and there were virtually no mega-spawners (0.2%). Bacalao fully recruit to the fishery 15 cm below the size at which 50% of the population matures. The Spawning Potential Ratio is currently 5% of potential unfished fecundity, strongly suggesting severe overfishing. Our results suggest the need for bacalao-specific management regulations that should include minimum (65 cm TL) and maximum (78 cm TL) landing sizes, slot limits (64–78 cm TL), as well as a closed season during spawning from October to January. It is recognized that these regulations are harsh and will certainly have negative impacts on the livelihoods of fishers in the short term, however, continued inaction will likely result in a collapse of this economically and culturally valuable species. Alternative sources of income should be developed in parallel with the establishment of fishing regulations to limit the socio-economic disruption to the fishing community during the transition to a more sustainable management regime.

Wild Berry Harvests Less Reliable According to Alaskan Local Observers
A new study from USGS, ANTHC, and the Local Environmental Observer (LEO) Network, provides a view statewide trends in wild berry harvests. The authors conclude that monitoring and experimental studies are needed to understand how climate change may affect the species of wild berries that are important to Alaskans. They also recommended that methods by which rural communities can increase their resilience to declining or more variable berry harvests be explored.

Climate change threatening Indigenous ways of life
Cecelia Brooks remembers a time when the deep forest of New Brunswick was so cold, snow could still be found in its depths in August. That rarely happens anymore. Brooks, who lives on St. Mary's First Nation in Fredericton, is one of many Indigenous people in the Wabanaki region who say climate change is threatening traditional plants and medicines. Those changes, Brooks says, could alter their way of life.
