The evergreen laurel forest is a relic of ancient subtropical/tropical forests, of which the best remnant in the Canary Islands is in Garajonay National Park, on La Gomera island. The soil microbiome associated with a mature undisturbed (unburned) laurel forest was characterized at two locations at different topographical positions on the mountain: The slope and the ridge crest. Given the unusual circumstance of an intense wildfire that severely affected part of this forest, the burned soils were also studied. The soil in undisturbed areas was relatively uniform. The bacterial community composition was dominated by bacteria from phyla Proteobacteria, Acidobacteria, and Actinobacteria. The wildfire changed the composition of the bacterial communities. The Acidobacteria, Actinobacteria, and Alphaproteobacteria (dominant class in unburned forests) significantly decreased in burned soils along with a parallel high increase in Betaproteobacteria, Bacteroidetes, and Firmicutes. We further showed the dramatic effect of a wildfire on the soil microbiome of the laurel forest, appearing as a loss of species richness and diversity, species dominance, and changes in the composition of the bacterial communities.

Abstract. Field measurements from February 2003 to January 2004 in a humid (but dry in summer) crest heath wood-land (degraded laurel forest) in the National Park of Garajonay, Canary Islands (Spain), were combined to calculate water balance components. The water balance domain is at the surface of the catchment and is controlled by atmospheric processes and vegetation. This study found that annual water income (rainfall plus fog water) was 1440 mm year-1, half of which was occult (or fog) precipitation, while stand transpiration estimated from measurements of sap flow amounted, annually, to 40% of potential evapotranspiration calculated from measurements of meteorological variables. The positive role of crest laurel forests, which transpire less water than is incoming from rain and fog is emphasised. Keywords: laurel forest, fog interception, stand transpiration, sap flow, hydrological cycle

Yanes et al. (2011) assume that the endemic Discidae from the Madeiran and Canarian Islands are members of the single genus Atlantica Ancey, with Atlantica s.str. and Canaridiscus Alonso & Ibañez as subgenera. As long as the anatomy of the type-species of Atlantica [Discus guerinianus (R.T. Lowe) from Madeira] is not known however, we do not follow this designation but maintain the genus Discus with the subgenera Atlantica and Canaridiscus. The subgenus Canaridiscus has been established by Alonso & Ibañez (in Yanes et al. 2011) for two newly discovered Canarian species, anagaensis Ibañez & D. Holyoak from the northeastern Anaga mountains (Tenerife), and saproxylophagus Alonso, G. Holyoak & Yanes from the National Park of Garajonay (La Gomera). The most remarkable feature of the new taxon is the genital system with a long or very long penis, unknown in other Discidae. Here we deal with the occurence of an additional Canaridiscus species, living near Casas de Encherada in the eastern part of La Gomera, where it has been found hidden in narrow rock crevices.

A catalogue of epiphytic lichens from La Gomera (Canary Islands) is presented, especially from Garajonay National Park. 207 species are treated, many of which are new records from the island. Gyalideopsis muscicola var. gomerae is proposed as new. Gyalideopsis calabrica and Porina isidiata are proposed as synonyms of G. muscicola and Porina guaranitica, respectively. Helocarpon corticolum is reported for the first time from North America. New for Macaronesia are Arthonia vinosa, Arthopyrenia cinereopruinosa, Bacidina egenula, B. phacodes, Gyalecta truncigena, Lauderlindsaya acroglypta, Lecidea botryosa, L. erythrophaea, Lecidella achristotera, Lichinodium ahlneri, Ochrolechia arborea, Opegrapha vermicellifera, Pertusaria amara var. slesvicensis, Pseudevernia furfuracea var. ceratea, Pseudosagedia obsoleta, Strigula smaragdula and S. taylorii. New for the Canary Islands are Arthonia anglica, Arthothelium norvegicum, Blarneya hibernica, Calicium lenticulare, Catinaria montana, Haematomma sorediatum, Hypotrachyna taylorensis, Lecanora argentata, L. strobilina, Melaspilea diplasiospora, Micarea melaena, Ochrolechia androgyna, Pertusaria ophthalmiza, Psoroglaena stigonemoides, Pyrenula dermatodes, Scoliciosporum pruinosum and Trapeliopsis granulosa.

Five different species of Copepoda were extracted from a leaf litter sample collected on the top (at 2000 m a.s.l.) of a cloud forested mountain in El Cusuco National Park, Honduras. Three of them, one Cyclopidae and two Canthocamptidae are new to science, and are described herein. Olmeccyclops hondo sp. nov. is the second representative thus far known of this New World genus. Moraria catracha sp. nov. and Moraria cusuca sp. nov. are the first formally described members of the genus occurring in Central America. The concept of a “Moraria-group” is considered to be an artificial grouping and is limited here to the genera Moraria and Morariopsis only. The distributional range of this group is essentially Holarctic, with the mountainous regions inHonduras, and probably in westNicaragua, as the southernmost limits in theNew World.
