Zooplankton abundance reflects oxygen concentration and dissolved organic matter in a seasonally hypoxic estuary. Journal of Marine Science and Engineering, 10(3), (2022): 427, https://doi.org/10.3390/jmse10030427., Ocean deoxygenation, warming, and acidification resulting from global change and increasing nutrient inputs are major threats to marine ecosystems. Despite this, spatial and temporal patterns of oxygen availability and their impacts on marine life are understudied compared to warming and acidification, particularly in coastal tropical ecosystems. We measured the abundance of major groups of zooplankton in the context of five covarying environmental parameters [temperature, salinity, dissolved oxygen (DO), dissolved organic matter (DOM), and chlorophyll concentration] in a tropical estuary for one year. Partial least squares demonstrated that environmental conditions explained 20% of the variation in the community and found that temperature, salinity, DO, and DOM were most important (Variable Importance in Projection [VIP] > 0.8). A generalized linear model identified depth, DO, salinity, and chlorophyll as significant main effects, and temperature and DOM were also significant via two-way interactions (p < 0.05). When examined separately, the abundance of each zooplankton group was explained by a slightly different combination of environmental factors, but in all cases DO had large, significant effects, and in most cases DOM or its interactions were also significant. These results demonstrate that the seasonal cycle of hypoxia in this system significantly impacts the abundance of major zooplankton groups and likely also recruitment of benthic fauna through impacts on meroplankton and benthic-pelagic food webs., This research was funded by a Fulbright Fellowship awarded to J.B.W. and a Smithsonian Tropical Research Institute internship awarded to L.V.

This exhibition catalogue documents the work of 20 international artists and comprises five essays on the theme of the relationship between representation and sexuality. The authors consider Freud's remarks on Da Vinci, examine the psychological problem of representing sexuality, resketche the rise of a new counter-cinema and its commitment to decoding social convention of sexuality, explore this theme in regard to video art, and refer to the scopic drive. Biographical notes. Circa 100 bibl. ref.
