Mediterranean Type Ecosystems

The world’s mediterranean-type climate regions (including areas within the Mediterranean, South Africa, Australia, California, and Chile) have long been of interest to biologists by virtue of their extraordinary biodiversity and the appearance of evolutionary convergence between these disparate regions. Comparisons between mediterranean-type climate regions have provided important insights into questions at the cutting edge of ecological, ecophysiological and evolutionary research. These regions, dominated by evergreen shrubland communities, contain many rare and endemic species. Their mild climate makes them appealing places to live and visit and this has resulted in numerous threats to the species and communities that occupy them. Threats include a wide range of factors such as habitat loss due to development and agriculture, disturbance, invasive species, and climate change. As a result, they continue to attract far more attention than their limited geographic area might suggest. This book provides a concise but comprehensive introduction to mediterranean-type ecosystems. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate these regions although their management, conservation, and restoration are also considered.

Abstract Abu Bakr Khaal’s African Titanics (written in Arabic) and Jonny Steinberg’s A Man of Good Hope (written in English) track diasporic movements from the former Italian colonies of Eritrea and Somalia. Focusing on mobility as well as memory, both books trace complicated and unpredictable patterns of forced displacement and precarious settlement. African Titanics charts the journey from Eritrea to the shores of the Mediterranean and the sea crossing to Europe, while A Man of Good Hope follows the movement overland from Somalia to South Africa. Both texts delineate communities networked across national borders and propose an alternative geography formed by cultural commonality rather than geopolitical division. The essay draws on Christina Sharpe’s concept of the ‘wake’ as a means of understanding how migrant subjectivity and community are formed through the multiple forms of racialized violence experienced in transnational mobility.

Abstract. Recent years have seen a number of severe droughts in different regions around the world, causing agricultural and economic losses, famines and migration. Despite their devastating consequences, the Standardised Precipitation Index (SPI) of these events lies within the range of internal climate variability, which we estimate from simulations from the 5th phase of the Coupled Model Intercomparison Project (CMIP5). In terms of drought magnitude, regional trends of SPI over the last decades remain mostly inconclusive in observations and CMIP5 simulations, although Soil Moisture Anomalies (SMAs) in CMIP5 simulations hint at increased drought in a few regions (e.g. the Mediterranean, Central America/Mexico, the Amazon, North-East Brazil and South Africa). Also for the future, projections of meteorological (SPI) and agricultural (SMA) drought in CMIP5 display large uncertainties over all time frames, generally impeding trend detection. Analogue analyses of the frequencies rather than magnitudes of future drought display, however, more robust signal-to-noise ratios with detectable trends towards more frequent drought until the end of the 21st century in the Mediterranean, South Africa and Central America/Mexico. Other present-day hot spots are projected to become less drought-prone, or to display unsignificant changes in drought occurrence. A separation of different sources of uncertainty in drought projections reveals that for the near term, internal climate variability is the dominant source, while the formulation of Global Climate Models (GCMs) generally becomes the dominant source of uncertainty by the end of the 21st century, especially for agricultural (soil moisture) drought. In comparison, the uncertainty in Green-House Gas (GHG) concentrations scenarios is negligible for most regions. These findings stand in contrast to respective analyses for a heat wave indicator, for which GHG concentrations scenarios constitute the main source of uncertainty. Our results highlight the inherent difficulty of drought quantification and the uncertainty of drought projections. However, high uncertainty should not be equated with low drought risk, since potential scenarios include large drought increases in key agricultural and ecosystem regions.

First Time

Bluetongue virus (BTV) is the prototype species of the genus Orbivirus within the family Reoviridae. There are 24 (possibly 25) distinct serotypes of BTV, eleven of which have entered, or have been identified in Europe and the Mediterranean region since 1998 (types 1, 2, 4, 6, 8, 9, 11, 15, 16, 24 and 25). The first BTV to arrive in Greece during 1998 was serotype 9 (iso­late GRE1998/01), followed by BTV-16 (GRE1999/13) during 1999. BTV-9 spread to mainland Greece, South-Eastern Bulgaria and European Turkey during 1999, to Italy during 2000, then to Serbia, Montenegro, Kosovo, Macedonia, Bulgaria, Croatia, mainland Italy and Sicily in 2001. In 2002, BTV-9 was again identified in Bosnia, Bulgaria, Montenegro, Yugoslavia and Albania, and was identified in Libya for the first time in 2008. The whole genome was sequenced for representative field and vaccine strains of BTV-9 and 16 from the Mediterranean region, identifying the levels of genetic heterogeneity in each genome segment. The early European isolates of BTV-9 (1998 onwards) were identified as ‘eastern’ strains related to those from India, Indonesia and Australia. BTV-16 isolates are also eastern strains that are most closely related to strains from Turkey and the South African reference strain of type 16 (originally from Pakistan). Analyses of the more conserved genome segments coding for structural and non-structural proteins of BTV-9 (from Bosnia, Bulgaria, Greece and Turkey) and BTV-16 (from Greece and Turkey) show that the Eastern European isolates of these two serotypes have the remaining eight genome segments (1, 3, 4, 5, 7, 8, 9 and 10) with more than 99% similarity, in each case belonging to the same eastern lineage. These data show that the BTV-9 and 16 isolates that were circulating in the Mediterranean region are reassortants, with the majority of their genome seg­ments derived from a single parental lineage. However, the BTV-9 isolate from Libya (LIB2008/08) is more closely related to the western BTV-9 reference strain from South Africa than to the earlier BTV-9 isolates from Eastern Europe. Analysis of the more conserved segments of LIB2008/08 showed only 79.8–80.2% similarity with the eastern European BTV-9 isolates from the Eastern Mediterranean region, but 89–93.5% similarity with the BTV-9 reference and vaccine strains from South Africa. BTV-9 from Libya belongs to a distinct western lineage of viruses and represents both a new introduction to the Mediterranean region and a new threat to Europe.

Accidental Introduction

The Natal fruit fly, Ceratitis rosa Karsch, was described in 1887 from specimens collected at Delagoa Bay, Mozambique. By 1900 it was recognized as a pest of orchard fruits throughout much of KwaZulu Natal Province, Republic of South Africa, and is considered to be the most common fruit fly of economic importance in Rhodesia. Following its accidental introduction into the island of Mauritius about 1953, this fly became firmly established and largely replaced the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), as a pest of fruits. In South Africa the Natal fruit fly ranks second in importance only to the Mediterranean Fruit Fly, and at times it is an even more serious pest. This document is EENY-257 (originally published as DPI Entomology Circular 51), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
