Adaptive Management and Climate Change Adaptation: Two Mutually Beneficial Areas of Practice

Adaptive management (AM) is a rigorous approach to implementing, monitoring, and evaluating actions, so as to learn and adjust those actions. Existing AM projects are at risk from climate change, and current AM guidance does not provide adequate methods to deal with this risk. Climate change adaptation (CCA) is an approach to plan and implement actions to reduce risks from climate variability and climate change, and to exploit beneficial opportunities. AM projects could be made more resilient to extreme climate events by applying the principles and procedures of CCA. To test this idea, we analyze the effects of extreme climatic events on five existing AM projects focused on ecosystem restoration and species recovery, in the Russian, Trinity, Okanagan, Platte, and Missouri River Basins. We examine these five case studies together to generate insights on how integrating CCA principles and practices into their design and implementation could improve their sustainability, despite significant technical and institutional challenges, particularly at larger scales. Although climate change brings substantial risks to AM projects, it may also provide opportunities, including creating new habitats, increasing the ability to quickly test flow‐habitat hypotheses, stimulating improvements in watershed management and water conservation, expanding the use of real‐time tools for flow management, and catalyzing creative application of CCA principles and procedures.     

The prenatal diagnosis of the cerebro-hepato-renal syndrome of Zellweger

The prenatal diagnosis of the cerebro-hepato-renal syndrome of Zellweger (CHRS) was made by assaying the levels of very long chain fatty acids (VLCFAs) in amniotic fluid cell cultures, obtained by amniocentesis at 16 1/2 weeks of pregnancy. The family-at-risk, because they had previously borne a child with CHRS, accepted these results as indications of an affected fetus, and chose to terminate the pregnancy at 20 1/2 weeks of gestation. The diagnosis was confirned by the phenotype of the aborted fetus and the presence of markedly elevated levels of VLCFAs in fetal liver homogenates. The prenatal diagnosis of CHRS, which can now readily be determined from amniotic fluid cell cultures, is an important step in genetic counselling of families-at-risk for this disease.     

STORMWATER DETENTION BASINS AND RESIDENTIAL LOCATIONAL DECISIONS1

ABSTRACT: Residents of seven subdivisions with wet and dry stormwater basins were questioned about the role the basin played in their decision to purchase their home. They were asked to estimate the impact of such basins on the image of residential developments and on lot values. Respondents believed that wet basins contributed positively to subdivision image and that lots in developments with wet basins were more valuable than comparable lots in dry basin subdivisions. Lots adjacent to wet basins were perceived as the most valuable, while those adjacent to dry basins were considered the least valuable.     

A closer look at the effects of subordinate–supervisor age differences

Relational demography research has emphasized a similarity–attraction paradigm in explaining employees' reactions to demographic differences from other organizational members. This study examined similarity–attraction (nondirectional age differences) and status incongruence (directional age differences) predictions of age difference effects. The nondirectional and directional differences between the age of a subordinate and the ages of his or her immediate and higher‐level supervisors were used to predict employee absenteeism, citizenship, and work change behaviors. Results revealed that there were more significant and marginally significant directional age difference effects than nondirectional age difference effects on work outcomes. The implications of these results for organizations are discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Ironic evaluation processes: effects of thought suppression on evaluations of older job applicants

This research explored ironic evaluation processes initiated by suppression instructions conveyed during diversity training. Raters watched one of three training videos: a video providing information about age diversity and recommending that they try to suppress age‐related thoughts; a video providing information about age, sex, race, and ethnic diversity and recommending that they try to suppress demography‐related thoughts; or a control video containing no suppression recommendations. All raters then evaluated a series of job applicants. During the evaluation task, some raters were cognitively busy while others were not. Ironically, busy raters instructed to suppress age‐related thoughts evaluated an older applicant less favorably than raters in other conditions. These results suggest that organizational diversity training including instructions to suppress stereotypic thoughts may have detrimental effects on evaluations of non‐traditional job applicants if raters are cognitively busy when they implement these instructions.

Correction to: Status and trends of circumpolar peregrine falcon and gyrfalcon populations

While collating contributions and comments from 36 researchers, the coordinating authors accidentally omitted Dr. Suzanne Carrière from the list of contributing co-authors. Dr. Carrière’s data are described in Tables 1 and 3, Figure 2 and several places in the narrative. The new author list is thus updated in this article.
