Uppermost Limit, Extent, and Fluctuations of the Timberline and Treeline Ecocline in the Swiss Central Alps during the past 11,500 Years

Pollen and macrofossils were analyzed at two sites above today's treeline (or tree limit) in the Swiss Central Alps (Gouillé Loéré, 2503 m a.s.l., and Lengi Egga, 2557 m a.s.l.) to test two contrasting hypotheses about the natural formation of timberline (the upper limit of closed forest) in the Alps. Our results revealed that Pinus cembra--Larix decidua forests near timberline were rather closed between 9000 and 2500 B.C. (9600-4000 ¹⁴C yr BP), when timberline fluctuations occurred within a belt 100-150 m above today's tree limit. The treeline ecocline above timberline was characterized by the mixed occurrence of tree, shrub, dwarf-shrub, and herbaceous species, but it did not encompass more than 100-150 altitudinal meters. The uppermost limit reached by timberline and treeline during the Holocene was ca. 2420 and 2530 m, respectively, i.e., about 120 to 180 m higher than today. Between 3500 and 2500 B.C. (4700-4000 ¹⁴C yr BP) timberline progressively sank by about 300 m, while treeline was lowered only ca. 100 m. This change led to an enlargement of the treeline-ecocline belt (by ca. 300 m) after 2500 B.C. (4000 ¹⁴C yr BP). Above the treeline ecocline, natural meadows dominated by dwarf shrubs (e.g., Salix herbacea) and herbaceous species (e.g., Helianthemum, Taraxacum, Potentialla, Leontodon t., Cerastium alpinum t., Cirsium spinosissimum, Silene exscapa t., and Saxifraga stellaris) have been present since at least 11,000 cal yr ago. In these meadows tree and tall shrub species (>0.5 m) never played a major role. These results support the conventional hypothesis of a narrow ecocline with rather sharp upper timberline and treeline boundaries and imply that today's treeless alpine communities in the Alps are close to a natural stage. Pollen (percentages and influx), stomata, and charcoal data may be useful for determining whether or not a site was treeless. Nevertheless, a reliable and detailed record of past local vegetation near and above timberline is best achieved through the inclusion of macrofossil analysis.

A potential case of attitude change: The Spanish spoken in the city of Malaga and used on social network sites

The Spanish spoken in the city of Malaga, as Andalusian Spanish in general, was in the past often times considered an incorrect, low prestige variety of Spanish which was strongly associated with the poor, rural, backward South of Spain. This southern Spanish variety is easily recognised because of its innovative phonetic features that diverge from the national standard, even though in the past years in the case of some features a convergence to the standard could be observed. Despite its low prestige the local variety of Spanish is quite often used on social network sites, where it is considered as urban, fashion and cool. Thus, this paper aims at analysing whether the Spanish used in the city of Malaga is undergoing an attitude change. The study draws on naturally occurring speech, data extracted from Facebook and a series of questionnaires about the salience, attitude and perception of the local variety of Spanish. The influence of the social factors age and gender is analysed, since they are both known to play a crucial role in many instances of language change. The first is of special interest, as during the Franco dictatorship dialect use was not accepted in schools and in the media. Results show that, on the one hand, people from Malaga hold a more positive attitude towards non-standard features used on social network sites than in spoken language. On the other hand, young female users employ most non-standard features online and unsurprisingly have an extremely positive attitude towards this use. However, in spoken Spanish the use and attitude of some features is led by men and speakers educated during the Franco dictatorship, while other features, such as elision of intervocalic /d/, elision of final /ɾ/, /l/ and /d/ and ceceo, are predominantly employed by and younger speakers and women. These features are considered as salient in the local variety and work as local identity markers.
