First record in France and Italy of the high-altitude-living moth Dahlica wehrlii (Müller-Rütz, 1920) in the Mont-Blanc massif (Lepidoptera, Psychidae). The Lepidoptera Psychidae Dahlica wehrlii (Müller-Rütz, 1920), a species inhabiting high-altitude biotopes and up to now recorded only from Switzerland, is mentioned from the Mont-Blanc massif, both in France and in Italy. Observation conditions as well as biological elements are given.

Dinoflagellates of the genus Ceratium are generally marine organisms, but rare occurrences in freshwater have been observed in Brazil. In this paper we are recording for the first time the presence of Ceratium furcoides, an invasive species, in a shallow, natural intermittent pool formed at a high-altitude at the southern end of the Iron Quadrangle, an iron-mining district of Minas Gerais State (Southeast Brazil). Samples were collected in October and November of 2010 (rainy period). The population density of this organism observed in Lagoa Seca (“Dry Pool”) was very low, at most 4 ind L–1. Mountain lakes are extremely vulnerable to atmospheric deposition of organisms, making them valuable witnesses both of the many forms of impact arising from human activities and of the extended global connections that facilitate the dispersion and introduction of new species over great distances. Studies on the population dynamics of C. furcoides in natural tropical systems are still rare and very recent to the brazilian scenario and hence the monitoring of its dynamics and the potential impact on aquatic communities of its becoming established are essential to an understanding of the process of bioinvasion by this species.

Avec le réchauffement du climat, la dégradation du permafrost est à l'origine d'une intensification des processus géomorphologiques sur les versants de haute montagne. Dans les parois rocheuses, les écroulements se multiplient et leur volume augmente, posant des problèmes de sécurité non seulement à haute altitude (infrastructures, alpinistes), mais également pour les fonds de vallée. Cet article présente les travaux récemment menés dans le massif du Mont-Blanc sur la relation entre climat et écroulements à différentes échelles de temps, les effets des épisodes caniculaires et la répartition et l'évolution du permafrost de paroi. Under global warming, permafrost degradation tends to intensify geomorphological processes on high mountain slopes. In the perennially frozen rock walls, the number and volume of rockfalls is increasing, causing safety problems not only at high altitude (infrastructure, mountaineers) but also for the valleys. This article summarizes recent work carried out in the Mont-Blanc massif on the climate-rockfall relationship at different time scales, the effects of heat waves, and the distribution/evolution of rock wall permafrost.

There is a lack of knowledge regarding Lepidoptera species in altitudinal grassland areas, especially in the state of Santa Catarina, in southern Brazil. Here we report some records of Vanessa braziliensis (Moore, 1883) and Urbanus zagorus (Plötz, 1880) in high altitude areas. We have likely registered both the first record of U. zagorus for the state of Santa Catarina and the highest altitudinal record of V. braziliensis in Brazil.

Arria muscoamicta Unnahachote & Shcherbakov, sp. nov. is described based on a male from central Thailand. This is the first record of Arria Stål, 1877 from the country. The new species is closely allied to A. leigongshanensis (Ge & Shen, 2008) from China, differing by the absence of prozonal tubercles, the elongated pronotum, nine tibial anteroventral spines, and the truncated hindwings. The new species is a moss-camouflaging mantis living at high altitude. The taxonomic problems of the genus are briefly discussed.

Cypriconcha hypsophila n. sp. is described and illustrated from high-altitude freshwater bodies within the Argentine province of Catamarca, which represents the first record of this genus in South America. This paper also presents a taxonomical key for identification of all species within the genus. Some comments concerning how this particular species could have spread from the high mountains from the Nearctic region to those of the northwestern Andes are provided.

Parastacus brasiliensis promatensis subsp. n. is described from São Francisco de Paula, Rio Grande do Sul, Brazil. The animals were collected at an elevation of 850 m, representing the first record of Parastacidae at high altitude in Brazil. Subspecies recognition was performed through the analysis of morphometrical characters. Discriminant analysis was applied to compare P. brasiliensis promatensis subsp. n. with the known populations of P. brasiliensis (Von Martens, 1869) using residuals from 23 morphometric regressions (Canonical Correlation = 0.948). All variance was explained by function 1 (Pbrasiliensis promatensis centroid equal to 3.04; P. brasiliensis centroid equal to -2.78).
