  • Supplementary Materials Section S1. Tabernas
    SUPPLEMENTARY MATERIALS SECTION S1. TABERNAS BADLANDS The climatological conditions and the sparsely vegetated landscape of the study area justify the local name of “Desierto de Tabernas” (Tabernas Desert) (Lázaro, Rodrigo, Gutiérrez, Domingo, & Puigdefábregas, 2001). However, it does not meet the demanding climatic criteria for entry into the desert category. The main argument that can be given for it is that the climate of the zone is semi-arid. In addition, the vegetation cover is thick where it can be. The asymmetry present in many of the small catchments integrating these badlands is linked to the vegetation pattern. North to east facing hillslopes are larger, more stable and less steep. Here plant cover ranges from 20% to 40% in the area (Puigdefabregas, Sole, Gutierrez, del Barrio, & Boer, 1999). The opposite slopes are affected by erosion, shorter, steeper, and bare (Calvo- Cases et al., 2014). The Tabernas badlands cannot be considered as the result of a desertification process. There has been no misuse of resources here (at least until recently, see next section). In other words, this desolate landscape is not the result of overexploitation. The reason is that this territory, due to its complicated orography, has never harbored an economy capable of promote substantial land degradation. On the upper hillslopes, M. tenacissima used to be harvested for cellulose, while the footslope sedimentary fill was cultivated with rainfed cereal crops. Both types of land use ceased about 50 years ago (Puigdefabregas et al., 1999). It was also possible to find some irrigation confined to small areas by then. In Almería, the use of subsoil water in irrigation is a long-established and dominant practice (Sánchez-Picón, Aznar-Sánchez, & García-Latorre, 2011) and, although by far the greater part of the agricultural lands was not irrigated, irrigation has been the economic basis of Almería because of the high yields it produced (Latorre, García-Latorre, & Sanchez-Picón, 2001).

To provide more insights into this issue, we Microbiotic crust collected samples of moss biocrusts, fixed sand, and mobile sand from a watershed with semi-arid climate on the Microbial community composition Loess Plateau of China. The relative abundances and community diversities of soil bacteria and fungi of the Microbial community diversity samples were determined using high-throughput DNA sequencing. Finally, we analyzed the characteristics of Relative abundance of species bacterial and fungal community of the moss biocrusts and their relationships to the content of soil nutrients. Our High-throughput sequencing results showed that the moss biocrusts had 1048 bacterial OTUs (operational taxonomic units) and 58 fungal OTUs, and their Shannon diversity indexes were 5.56 and 1.65, respectively.

The status of CASG 71892 as the oldest known record of either of the two spp. of Uria was recently confirmed by the review of Watanabe et al. (2016). The younger of the two marine transgressions at the Tolstoi Point corresponds to the Bigbendian transgression (Olson, 2013), which contains the Gauss-Matuyama magnetostratigraphic boundary (Kaufman and Brigham-Grette, 1993). Attempts to date this reversal have been recently reviewed by Ohno et al. (2012); Singer (2014), and Head (2019). In particular, Deino et al. (2006) were able to tightly bracket the age of the reversal using high-precision 40Ar/39Ar dating of two tuffs in normally and reversely magnetized lacustrine sediments from Kenya, obtaining a value of 2.589 ± 0.003 Ma.

The history of this and other breeding colonies is outlined. The colony is in an oasis at the south-east side of the Hofsjökul in the centre of Iceland at a height of 2000 feet. Studies were mainly concentrated on marking, with a view to population measurement, and on behaviour. It was estimated that there were probably about 2300 nests in the oasis and that the population including adults and goslings may have been of the order of 13,000 birds. Recaptures of marked birds were used in making these estimates. Food, predation, nests, eggs and goslings, behaviour of parents and broods are described and discussed. Methods of capture were discovered which throw light on the functions of ancient ruined ‘goose-folds’ found in the area. Five large drives were made, in one of which 267 geese were caught. During the whole period 1151 geese and goslings were marked, some with Swedish-type wing-tags.

  • The Natural Magic of Aragon the Plus Points
    The Natural Magic Of Aragon This is a truly magical region in the foothills of the Spanish Pyrenees. It is packed with dramatic landscapes, thousand-year-old castles, hermitages built into cliff-faces, exceptionally quaint villages, great weather, wonderful walking, original places to stay, and distinctively Aragonese cuisine. 7 nights, 6 walking days Minimum required 2 From point to point With luggage transportation Self-guided Code : FP2PURI The plus points • Transfers from and to Zaragoza (other transfers available) • Luggage transfers every day so you only carry a daysack • Typical Arogonese hotels with dinner included • 24/7 customer service Before departure, please check that you have an updated fact sheet. https://www.purelypyrenees.com/natural_magic_aragon.html FP2PURI Last update 29/12/2020 1 / 14 Aragon is a truly enchanting kingdom, a world unto itself, and your walking holiday includes a village they say is at the end of the world. But the "magic" comes from the frequent surprises (natural and man made) you get whilst walking through this panoramic landscape. For example, on just one walk you will find stunning, pink cliffs rising a sheer 1,000 feet above you; ancient hermitages cut into rock; almost hidden shepherds' huts; panoramic views of the Ebro plain and the High Pyrenees mountains; an abandoned village; a Roman bridge; a lovely waterfall. And that is without talking about the "magical" light that characterises Aragon, or its distinctive cuisine and hotels. It is a real surprise that, with all this on offer, there are not many more foreign visitors. Unsurprisingly, we thoroughly recommend it. THE PROGRAMME DAY 1 Arrival at Zaragoza or Loarre Standard option: You drive yourself to you first night's hotel, which will be in Loarre.
