Symbiont 'bleaching' in planktic foraminifera during the Middle Eocene Climatic Optimum
Many genera of modern planktic foraminifera are adapted to nutrient-poor (oligotrophic) surface waters by hosting photosynthetic symbionts, but it is unknown how they will respond to future changes in ocean temperature and acidity. Here we show that ca. 40 Ma, some fossil photosymbiont-bearing planktic foraminifera were temporarily ‘bleached’ of their symbionts coincident with transient global warming during the Middle Eocene Climatic Optimum (MECO). At Ocean Drilling Program (ODP) Sites 748 and 1051 (Southern Ocean and mid-latitude North Atlantic, respectively), the typically positive relationship between the size of photosymbiont-bearing planktic foraminifer tests and their carbon isotope ratios (?13C) was temporarily reduced for ?100 k.y. during the peak of the MECO. At the same time, the typically photosymbiont-bearing planktic foraminifera Acarinina suffered transient reductions in test size and relative abundance, indicating ecological stress. The coincidence of minimum ?18O values and reduction in test size–?13C gradients suggests a link between increased sea-surface temperatures and bleaching during the MECO, although changes in pH and nutrient availability may also have played a role. Our findings show that host-photosymbiont interactions are not constant through geological time, with implications for both the evolution of trophic strategies in marine plankton and the reliability of geochemical proxy records generated from symbiont-bearing planktic foraminifera
New biostratigraphic, magnetostratigraphic and isotopic insights into the Middle Eocene Climatic Optimum in low latitudes
The Middle Eocene Climatic Optimum (MECO) was a warming event that interrupted the long-term Eocene cooling trend. While this event is well documented at high southern and mid-latitudes, it is poorly known from low latitudes and its timing and duration are not well constrained because of problems of hiati, microfossil preservation and weak magnetic polarity in key sedimentary sections. Here, we report the results of a study designed to improve the bio-, magneto- and chemostratigraphy of the MECO interval using high-resolution records from two low-latitude sections in the Atlantic Ocean, Ocean Drilling Program (ODP) Sites 1051 and 1260. We present the first detailed benthic foraminiferal stable isotope records of the MECO from the low latitudes as well as the biostratigraphic counts of Orbulinoides beckmanni and new magnetostrati-graphic results. Our data demonstrate a similar to 750 kyr-long duration for the MECO characterized by increasing delta(13)C and decreasing 6180, with minimum 6180 values lasting similar to 40 kyr at 40.1 Ma coincident with a short-lived negative delta(13)C excursion. Thereafter, 6180 and delta(13)C values recover rapidly. The shift to minimum 6180 values at 40.1 Ma is coincident with a marked increase in the abundance of the planktonic foraminifera O. beckmanni, consistent with its inferred warm-water preference. O. beckmanni is an important Eocene biostratigraphic marker, defining planktonic foraminiferal Zone E12 with its lowest and highest occurrences (LO and HOs). Our new records reveal that the LO of O. beckmanni is distinctly diachronous, appearing similar to 500 kyr earlier in the equatorial Atlantic than in the subtropics (40.5 versus 41.0 Ma). We also show that, at both sites, the HO of O. beckmanni at 39.5 Ma is younger than the published calibrations, increasing the duration of Zone E12 by at least 400 kyr. In accordance with the tropical origins of O. beckmanni, this range expansion to higher latitudes may have occurred in response to sea surface warming during the MECO and subsequently disappeared with cooling of surface waters.

Author Correction:A cattle graph genome incorporating global breed diversity
The original version of this Article omitted from the author list the 12th and 13th authors Dennis Muhanguzi and Wilson Amanyire, who are from the ‘School of Biosecurity, Biotechnology and Laboratory Sciences (SBLS), College of Veterinary Medicine, Animal Resources and Biosecurity, Makerere University, P.O Box 7062, Kampala, Uganda’.

Czyje jest miasto? Kilka uwag o jednej powieści K.M. Bakowa
The article looks at the question of using urban studies as a set of interpretive techniques in analyzing popular literature – especially in its most popular genre – crime fiction. On the basis of K.M. Bakow’s debut novel Albatros i hiena [Albatross and hyena], set in Bielsko-Biała, the author of the article shows how the criminal intrigue is enriched by a specific way of showing urban space and how it relates to the main character, detective Ewa Orlowska. The proposed model of interpretation can be used
in discussing subsequent novels by the author of Padlinożercy [Scavengers] and fits into the framework of geopoetics and text [email protected] Literaturoznawstwa, Uniwersytet ŚląskiBakow K. M.

Internet Identifiability and Beyond: A Model of the Effects of Identifiability on Communicative Behavior
K.M. Douglas and C. McGarty (in press) demonstrated that being identifiable to an ingroup
audience in a computer-mediated communication (CMC) setting leads people to describe
anonymous outgroup targets in more abstract, or stereotypical ways. Based on these findings,
and on the social identity model of deindividuation effects (SIDE: S.D. Reicher, R. Spears,
& T. Postmes, 1995), we aimed to test a model of the effects of identifiability on
communicative behavior, in and beyond CMC. Participants in three studies, one CMC and
two pen/paper, were asked to write responses to controversial messages. In all three studies,
communicators who were identifiable to an ingroup audience used more stereotypical
language to describe anonymous outgroup targets. Although Study 1 suggested that this
increase in stereotypical language use may be strategic, Studies 2 and 3 suggested instead that
it may result from more subtle, or implicit communicative processes. These results are
discussed in relation to the revised SIDE model and a final model is proposed
