Galapagos Penguin

Long-term monitoring of the Galapagos Penguin (Spheniscus mendiculus) indicates that the population is fluctuating, primarily as a result of marine perturbations that may be becoming more extreme through climate change. These perturbations have caused an overall very rapid population reduction over the last three generations (31 years). In addition, the species has a small population…

Jico Deer Mouse

Jico Deer Mouse (Habromys simulatus) is listed as Critically Endangered because it is known from only two subpopulations: one is likely now extinct, and the other has extremely low population numbers (less than or equal to 50). Most of the mature individuals from are in one subpopulation. If more habitat continues to disappear, this species…
