Our Lady of Guadalupe : contemporary explorations of personal and cultural identity

Since it first appeared, the image of Our Lady of Guadalupe has remained relatively unchanged. In the last thirty-five years, however, this has been changing. Artists are creating new variations of the icon to represent and express their reinterpretations. In some of these more contemporary images, the figure of Guadalupe has changed dramatically, but still retains enough traditional elements to be easily recognizable. Some of these images have been received with mixed results and have even sparked major controversy. These new, and sometimes controversial depictions of Guadalupe, specifically those created by Ester Hernández, Yolanda M. López and Alma López, will be explored here. Although each artist has her own individual motivations and intentions, all of the images presented here explore personal and cultural identity, as well as seek in some way to honor ordinary, human women through the sacred iconography of Our Lady of Guadalupe.

Recent advances in our knowledge of the biology and conservation of mahseers

Mahseers (Tor khudree), at one time considered to be of single species, are now represented by 6 valid species distributed all over India. Studies on their food habits, ecology of spawning grounds, eggs, larval development and especially methods of artificial propagation have advanced in recent years. Transport of eggs of Tor khudree by air in moist cotton has been possible for easy distribution. Breeding of T. khudree not only by hypophysation, but even without it in small ponds by manipulation of flow of water, exercise and feed has also been possible. Fry and fingerlings of T. khudree are being distributed to many of the states in the country to help conserve the species.

Holocene environmental changes in the lower Thames Valley, London, UK: implications for our understanding of the history of Taxus woodland

A radiocarbon-dated multiproxy palaeoenvironmental record from the Lower Thames Valley at Hornchurch Marshes has provided a reconstruction of the timing and nature of vegetation succession against a background of Holocene climate change, relative sea level movement and human activities. The investigation recorded widespread peat formation between c. 6300 and 3900 cal. yr BP (marine ‘regression’), succeeded by evidence for marine incursion. The multiproxy analyses of these sediments, comprising pollen, Coleoptera, diatoms, and plant and wood macrofossils, have indicated significant changes in both the wetland and dryland environment, including the establishment of Alnus (Alder) carr woodland, and the decline of both Ulmus (Elm; c. 5740 cal. yr BP) and Tilia (Lime; c. 5600 cal. yr BP, and 4160–3710 cal. yr BP). The beetle faunas from the peat also suggest a thermal climate similar to that of the present day. At c. 4900 cal. yr BP, Taxus (L.; Yew) woodland colonised the peatland forming a plant community that has no known modern analogue in the UK. The precise reason, or reasons, for this event remain unclear, although changes in peatland hydrology seem most likely. The growth of Taxus on peatland not only has considerable importance for our knowledge of the vegetation history of southeast England, and NW Europe generally, but also has wider implications for the interpretation of Holocene palaeobotanical records. At c. 3900 cal. yr BP, Taxus declined on the peatland surface during a period of major hydrological change (marine incursion), an event also strongly associated with the decline of dryland woodland taxa, including Tilia and Quercus, and the appearance of anthropogenic indicators.
