    Records and descriptions are given for the 10 known species in six genera of Bruchidae from the Archipelago including Sennius falcatus New Species and Acanthoscelides rossi New Species. Amblycerus (Spermophagus) insulamm (Blair) is synonymized with Amblycems piurae (Pierce), New Synonymy. Five of the species herein treated are new records for the Archipelago, and 8 of the 10 are also known from mainland South America, principally Ecuador

    Talk of \u27Broken Borders\u27 and Stone Walls: Anti-immigrant Discourse and Legislation from California to South Carolina

    Get PDF
    The anti-immigrant sentiments that propelled the passage of California Proposition 187 in 1994 – linked to an economic downturn and worries about NAFTA – have been echoed across the U.S. over the intervening sixteen years. This article briefly reviews public discourse about anti-immigrant legislation in a wave of other states from California to South Carolina, and discusses the convergence of anti-immigrant and white supremacist projects in the U.S., using the concepts of market citizenship and citizen surveillance. As new anti-immigrant legislation is proposed in the South, understanding it within its national and historical context is important. This discussion includes consideration of the role of metaphor in both fueling and countering anti-immigrant discourse

    A Selected Bibliography of Insect-Vascular Plant Associations in the United States and Canada

    This item was bound with Insect Identification Notes 1-3, and has a handwritten note on the title page "Identification Note no. 4". It also has a typewritten "F-4" in the lower left corner which is not present in other issues of the series. The topic seems out of scope for the Insect Identification Note series, and it may in fact not be part of this series.Ope

    Quantifying thermal extremes and biological variation to predict evolutionary responses to changing climate

    Get PDF
    Central ideas from thermal biology, including thermal performance curves and tolerances, have been widely used to evaluate how changes in environmental means and variances generate changes in fitness, selection and microevolution in response to climate change. We summarize the opportunities and challenges for extending this approach to understanding the consequences of extreme climatic events. Using statistical tools from extreme value theory, we show how distributions of thermal extremes vary with latitude, time scale and climate change. Second, we review how performance curves and tolerances have been used to predict the fitness and evolutionary responses to climate change and climate gradients. Performance curves and tolerances change with prior thermal history and with time scale, complicating their use for predicting responses to thermal extremes. Third, we describe several recent case studies showing how infrequent extreme events can have outsized effects on the evolution of performance curves and heat tolerance. A key issue is whether thermal extremes affect reproduction or survival, and how these combine to determine overall fitness. We argue that a greater focus on tails-in the distribution of environmental extremes, and in the upper ends of performance curves-is needed to understand the consequences of extreme events.This article is part of the themed issue 'Behavioural, ecological and evolutionary responses to extreme climatic events'

    Visualizing genetic constraints

    Get PDF
    Principal Components Analysis (PCA) is a common way to study the sources of variation in a high-dimensional data set. Typically, the leading principal components are used to understand the variation in the data or to reduce the dimension of the data for subsequent analysis. The remaining principal components are ignored since they explain little of the variation in the data. However, evolutionary biologists gain important insights from these low variation directions. Specifically, they are interested in directions of low genetic variability that are biologically interpretable. These directions are called genetic constraints and indicate directions in which a trait cannot evolve through selection. Here, we propose studying the subspace spanned by low variance principal components by determining vectors in this subspace that are simplest. Our method and accompanying graphical displays enhance the biologist's ability to visualize the subspace and identify interpretable directions of low genetic variability that align with simple directions.Comment: Published in at http://dx.doi.org/10.1214/12-AOAS603 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org
