  • Hybrids and Hybrid Zones
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Digital.CSIC Hybrids and hybrid zones Arnold’s new book on hybridization1, recently reviewed by Ritchie in TREE 2, has brought attention to an old, controversial but revitalized topic in evolutionary biology. The two reviews2,3 we have read share a sceptical attitude towards studies of hybridization lying outside the hybrid zone theory. They consider Arnold’s book too ‘opinionated’2 and ‘an argument for a greater emphasis on the positive role of hybridization in evolution’ rather than a ‘comprehensive review’3. However, one of the merits of the book is that it devotes a great deal of effort towards reconciling divergent approaches to the topic. Arnold dedicates equal importance to animal and plant studies, as acknowledged by Ritchie2, and also puts much emphasis on the analysis of hybrid zones. In fact, when proposing a model for the birth of new evolutionary hybrid lineages he places his ‘new conceptual framework (the evolutionary novelty model)’ within the hybrid zone framework. Our criticism of this proposal is that it may be too rigid to fit scenarios departing from the specific model of hybrid speciation proposed by Grant4, that is, recombinational speciation. In our opinion, relying exclusively on the hybrid zone framework to assess the role of hybrids in evolution is misleading. Hybrid zones usually imply relatively recent events and species with strong reproductive barriers. The tension zone model assumes that hybrid zones are maintained by a balance between selection against hybrid individuals and dispersal of parental individuals into the hybrid zone5.

Despite the genetic tractability of many of Drosophila species, the genus has few examples of the ``classic'' type of hybrid zone, in which the ranges of two species overlap with a gradual transition from one species to another through an area where hybrids are produced. Here we describe a classic hybrid zone in Drosophila that involves two sister species, Drosophila yakuba and D. santomea, on the island of SaÄo TomeÂ. Our transect of this zone has yielded several surprising and anomalous ®ndings. First, we detected the presence of an additional hybrid zone largely outside the range of both parental species. This phenomenon is, to our knowledge, unique among animals. Second, the genetic analysis using diagnostic molecular markers of the ¯ies collected in this anomalous hybrid zone indicates that nearly all hybrid males are F1s that carry the D. santomea X chromosome. This F1 genotype is much more dif®cult to produce in the laboratory compared to the genotype from the reciprocal cross, showing that sexual isolation as seen in the laboratory is insuf®cient to explain the genotypes of hybrids found in the wild.

ABSTRACT Lake Uluabat, having an international significance and subject to the Ramsar Convention, is fed by the basin of Musta- fakemalpaşa Stream which runs through fertile lands utilized for livestock breeding and agriculture. In this study, total amount of nitrogen (TN) and phosphorus (TP) loads of non-point pollutants (agriculture, livestock breeding, vegetation, surface runoff and small settlements) was calculated. It was found out that most intensive pollution load stemmed from livestock breeding which causes dispersion of 13653.57 tons·year−1 of TN and 3224.45 tons·year−1 of TP into the Lake Uluabat. Additionally, seasonal changes in concentration of TN and TP were observed during the period of 2008-2009 in Lake Uluabat. It was concluded that the rise of agricultural activities in summer months was the reason underlying the increase in pollution during the months in question.

These two well-defined species are of special interest because of complex interactions at their contact zone, which include hybridization, species replacement and asymmetric mitochondrial DNA introgression. In common garden experiments, females were introduced to conspecific males, to males of other species and to hybrid males. We monitored the total number and size of the deposited eggs, as well as the dynamics and duration of oviposition during three consecutive years. The number of deposited eggs of Triturus species was much higher than previously reported. Triturus macedonicus lay more eggs that were of larger size in comparison to T. ivanbureschi. Also, the onset of T. macedonicus oviposition was considerably delayed compared to T. ivanbureschi. These are fundamental data, important for understanding complex species interactions in their contact zones.

  • Hybridization & Conservation Natural Hybridization Can Create Genetic
    Hybridization & Conservation Natural hybridization can create genetic diversity, e.g. plant species of hybrid origin, genetic exchange among micro-organisms. But genetic hybridization due to human disturbances (particularly introduced species, but also habitat fragmentation modification) can compromise the genetic integrity of existing species to the point of causing extinctions. New Zealand grey duck (Anas superciliosa) hybridizes with introduced mallards (Anas platyrynchos). · Mallards are common but NZ greys are rare. · So NZG tend to mate with mallards, simply b/c more readily available. · So pure NZG are disappearing rapidly. · The same pattern is true for mallards hybridizing with and genetically swamping endemic Hawaiian ducks (A wyvilliana) and Australian black ducks (A rogersi). Northern spotted owls (Strix occidentalis caurina) declined to low numbers by loss of old growth forest. NSO now rare and logged habitat is being colonized by barred owl (Strix varia), which produces fertile hybrids with NSO. If BO become more common than NSO, genetic swamping is a risk. Example shows how habitat modification can create hybridization problems. Ethiopian wolf (Canis simensis) and domestic dog (C. familiaris). C. simensis has become rare (< 500 individuals) as afro-alpine habitat has become fragmented.

Due to concerns about potential pollution resulting from watershed sources and adjacent agricultural lands, a study of the trophic state of lake Uluabat was conducted during the period February 2003 to January 2004. Total nitrogen (TN), total phosphorus (TP), Secchi disc depth (SD) and chlorophyll a (Chly a) were analyzed monthly in order to assess the trophic state of the lake. According to calculated nutrient ratios, phosphorus was found to be the primary limiting nutrient in lake Uluabat.

As it was the case during his productive academic years, we wish successful, happy and healthy years to Professor Kiziroglu during his retirement years as well. A short resume of Professor Kiziroğlu is presented below. Symposium Organizing Committee Resume of Professor Dr. İLHAMİ KİZİROĞLU İlhami Kiziroğlu, born in Elazığ/Harput, graduated from Istanbul University, having a Senior Forest Engineering diploma in 1968. He has been awarded a scholarship and went to Germany for his masters and doctorate studies. He carried out his pre-doctorate study on spiders at the “Institut für angewandte Zoologie” in Munich Ludwigs- Maximillian University.

Invasions, 2011, 2 Abstract Distribution and impacts of Carassius species (Cyprinidae) in Turkey: a review Biological invasions have caused considerable disruption to native Deniz INNAL ecosystems throughout the world through predation, habitat alteration, competition and hybridisation with Introduction, Hypotheses and species have been introduced in native species and introduction of Problems for Management Turkey as eggs, fry or fingerlings for diseases or parasites. Species of the different purposes over the last five genus Carassius [C. auratus (Linnaeus, In Europe, three species of the decades. Some of these fish have 1758), C. carassius (Linnaeus, 1758) and genus Carassius Nilsson 1832, are been used only in closed systems C. gibelio (Bloch, 1782)] were known; the goldfish, Carassius while others have been released transported to numerous inland water auratus (Linnaeus, 1758), the into open inland waters throughout bodies throughout Turkey.
