The diet of Bubo ascalaphus was studied in a steppe at the Mergueb nature reserve. The analysis of 141 pellets indicated that mammals were most abundant (89 %). The most frequent prey, on a numerical basis (82 %) as well as in term of biomass (96 %) was Meriones shawi trouessarti (Gerbillidae). Other preys included Jaculus orientalis (Dipodidae), and two insectivores: Crocidura russula and Hemiechinus aethiopicus. Among the avifauna, only the Spanish sparrow (Passer hispaniolensis) was a significant part of the Eagle owl dietn especially in spring. Arthropods were represented by Scarabeidae in spring and Scorpionidae in summer but they played a minor role in the food of the Eagle owl. The originality of this diet lies in the absence of Brown hare (Lepus capensis) and the presence of only one specimen of the desert hedgehog. Although its food spectrum was very narrow in this site, the Eagle owl can be regarded as opportunistic as it concentrated on the most available prey: Meriones shawi. [less ▲]

The diet of European marsh harrier was studied from 555 pellets collected in the Marais de Brouage (Charente-Maritime) during four winters distributed over a 17 years period (1985-86 / 2001-02). A total of 1074 prey items (70 taxa) were identified. The mammals are the most numerous (62.6%); three rodents represent half of the prey. The increase of coypu (Myocastor coypus) is the most important interannual variation, they currently represent more than the thrid of the prey [less ▲]

Over the course of last two decades, Mexico’s policies towards its population abroad has moved from a situation characterized by a general lack of interest to being one of the most active state in this field. The recent development of dual national and external voting policies as well as the creation of a dedicated government agency and of a consultative body all epitomize the radical change through which Mexico has gone. In this chapter, I argue that the transformation of Mexico’s attitude towards its emigrants is strongly connected to the evolution of its political regime characterized by a transition towards democracy, a strong desire to take part actively in the global economy and the increasing interest of regional actors in migration issues. Focusing on the issue of external voting, the chapter concludes by discussing the evolution of the power relations between the emigrant community and the Mexican state. [less ▲]

Fifty six otter spraints were collected along three oligotrophic streams of Central Brittany, from 1982 to 1985. Pry items were identified, enumerated, and their size estimated, using the same criteria as those previousely used by Hallet (1977-1985) in her study of the diet of the Kingfisher (Alcedo atthis). Among the 251 prey items belonging to 11 taxa, small fish species such as the bullhead (Cottus gobio) and the minnow (Phoxinus phoxinus) were the most abundant. From the trophic point of view, however, their importance was rather negligible, since their biomass made up 10 % only of the overall biomass ingested. Large prey, such as trout (Salmo trutta), birds and mammals, made up the bulk of the otter diet in this area. [less ▲]

Otter spaints were collected in 1991 on a seasonal basis in the river Chavanon catchment, a tributary of the river Dordogne, in central France. Small sized species (bullhead, three-spined stickleback, gudgeon and minnow) are the most numerous items in the diet: they account for more than 50% of the 3,148 identified preys. However, when expressed in relative biomass, their importance falls down (8 %). In fact, the brown trout, large cyprinid fish, birds and mammals make up the bulk of the diet. We found strong differences linked to the general habitat types and also seasonal ones. Frogs are mainly preyed upon during the spring whereas the snakes are exclusively taken in the summer and autumn months. Gudgeon and insects are also mainly summer and autumn preys. Perch and large cyprinid fish remais are more frequent during winter and even spring. The present results confirm the opportunistic way of predation of the otter and the fact that its hunting takes place more on the bottom and along the river banks than in the open water. [less ▲]

More than 1500 otter spraint samples have been collected in different aquatic habitats throughout the present geographic range of the otter in France. Prey remains were identified, the relative occurrence and abundance of each species was assessed and the biomass of each individual prey estimated. When available, data about the fish communities (size frequency- distributions, relative abundance) were compared with the diet of the mustelid. The main conclusions of the study are as follows: 1. The otter is mainly piscivorous but some other aquatic (crayfish) or semiaquatic preys (frogs, Natrix-snakes, some birds and mammals) are of major dietary importance in oligotrophic habitats. 2. The composition of the diet is determined by the local fish resources. The otter is an opportunistic predator, its diet varying greatly from one place to another. The diet can also change depending upon the season or upon some special circumstances such as frog or fish reproduction or strong prey-community changes. 3. Small fish are dominant in the diet. No size selection has been evidenced at least in the eel and in the cyprinid fishes. As far as the trout is concerned, it seems that the otter consumes preferably medium sized individuals. 4. The proportion of some prey species is lower in the diet than in the habitat. These are the more pelagic (bleak, sander, breams), rheophilic (dace, chub) or group-living species (minnow, roach). Bottom- (bullhead, eel, tench, gudgeon, barbel) or plant-living (rudd, pike) species are more frequent. [less ▲]
