Phytoplankton is a sentinel of marine ecosystem change. Composed by many species with different life-history strategies, it rapidly responds to environment changes. An analysis of the abundance of 54 phytoplankton species in Galicia (NW Spain) between 1989 and 2008 to determine the main components of temporal variability in relation to climate and upwelling showed that most of this variability was stochastic, as seasonality and long term trends contributed to relatively small fractions of the series. In general, trends appeared as non linear, and species clustered in 4 groups according to the trend pattern but there was no defined pattern for diatoms, dinoflagellates or other groups. While, in general, total abundance increased, no clear trend was found for 23 species, 14 species decreased, 4 species increased during the early 1990s, and only 13 species showed a general increase through the series. In contrast, series of local environmental conditions (temperature, stratification, nutrients) and climate-related variables (atmospheric pressure indices, upwelling winds) showed a high fraction of their variability in deterministic seasonality and trends. As a result, each species responded independently to environmental and climate variability, measured by generalized additive models. Most species showed a positive relationship with nutrient concentrations but only a few showed a direct relationship with stratification and upwelling. Climate variables had only measurable effects on some species but no common response emerged. Because its adaptation to frequent disturbances, phytoplankton communities in upwelling ecosystems appear less sensitive to changes in regional climate than other communities characterized by short and well defined productive periods.

Dealing with Shifting Labor Employment Sands

Changes in regulations and tighter interpretations of existing regulations engaged participants in 14th annual Labor and Employment Roundtable, hosted by the Cornell Institute for Hospitality Labor and Employment Relations. They also reviewed changes in union organizing rules. Two Supreme Court decisions dealt with the challenging application of accommodating workers’ health and religious needs, while a new ruling by the National Labor Relations Board calls into question the supposedly arm’s length relationship of employee leasing firms and their clients, as well as franchisors and franchisees. The NLRB also has shortened the campaign time for union elections. In one Supreme Court case, Young v. United Parcel Services, Inc., the Court pointed to a simple principle when employers implement policies for those with illness or medical conditions. Policies must be consistent with regard to how on-job and off-job health issues are treated, and the company’s policy must not be driven by economic considerations. That is, the Court stated that an employer’s denial of a light-duty assignment for an employee could not be based on cost or convenience. The case relating to religious accommodation also involved an economic hinge. In an earlier case, the Court had held that religious accommodations are limited to that which would have no more than a de minimus cost on the employer. In this case, EEOC v. Abercrombie & Fitch Stores Inc., Abercrombie had declined to hire a woman wearing a headscarf on the assumption that she would need a religious accommodation. The Court frowned on the idea that an employer would take religious accommodations into account when deciding whether to hire a person. The franchising industry is attempting to make sense of the NLRB ruling regarding joint employment, in which the board ruled that franchisors that maintain some kind of control over their franchisees’ employees should be considered joint employers of those employees. This is a complicated matter, and the situation is still in flux. Finally, with regard to the telescoped union campaign ruling, these are supposed to benefit the unions. So far, however, there’s no indication that the change has affected the overall outcome of union election campaigns.
