The Atacama “puna” (high-altitude plateau) is situated among the high peaks of the Andes at over 4000 m a.s.l. This ecosystem covers parts of north-eastern Chile, north-western Argentina, south-eastern Peru, and mid-western Bolivia. The puna brings together several types of wetlands, such as salt-flats, lakes, rivers, high marshes, and highland bogs. Highland bogs are peatlands associated with endorheic basins. The object of this study was to analyse the specific composition and structure of the zooplankton of the bogs of the Putana River, on the Altiplano of northern Chile. In 2012, zooplankton samples were taken for qualitative and quantitative analysis at nine stations of the bog. Nine taxa of zooplanktonic crustaceans were recorded. The species richness is higher than records in other high Andean wetland at a similar altitude, although the species found have been reported for other high Andean wetlands and Andean lakes in Chile and from neighbouring countries.

Abstract The Atacama is the world’s driest desert. It contains various types of wetlands. In general, the diversity and structure of the zooplankton in these wetlands have been very little studied. The object of the present study was to analyse the specific composition and structure of the zooplankton in a transect which included highland bogs and an endorheic mountain river in the Altiplano of northern Chile. In 2017, samples of zooplankton were collected for qualitative and quantitative analysis in two types of wetlands. Eight taxa of zooplanktonic crustaceans were recorded. The results of null models revealed the absence of regulator patterns for all sites in species co-occurrence. Cluster analysis generated two groups with low similarity between them. The results observed in the correlation matrix showed significant direct associations between some species and the level of dissolved oxygen, conductivity and salinity.

Study Sites

An important aim of fish ecology is to understand and predict patterns of distribution and abundance in marine communities. Such patterns were examined at four kelp-dominated sites along the northern coast of Chile (19° through 30° S) over 1 year. Fish species richness, diversity and abundance estimates obtained via observational and destructive sampling methods were compared among sites as were habitat and environmental variables that characterised the sites; including sea water temperature below the surface, nutrients, productivity, visibility, density of macroalgae stands, and percentage cover of observed microhabitats (including understorey algae and faunal assemblages). In total, 19 fish species belonging to 14 families were observed from all sites. Species richness and diversity were highest in sites where kelp canopy was composed of two species and where kelp was densest, although only species diversity was significantly different among sites. The sites with high kelp density, in turn, sustained abundant habitat-forming species in the kelp understorey. Principal coordinate analysis indicated that the composition and structure of the fish assemblages varied significantly with depth at all study sites. The depth distribution of fishes was correlated with the arrangement of site-specific biological microhabitats, defined by the algae or invertebrate species that form the microhabitat. Temperature, productivity, and nutrients did not vary consistently across study sites, but did vary within individual sites. We suggest that kelp cover and composition strongly affects the diversity and distribution of fishes at shallow coastal habitats in northern Chile through the availability of microhabitats.

Sindhupalchok is one of the largest districts of central Nepal with area occupancy of about 2542 km². The northern side of this district exhibits complex physical feature where this study was carried out within the elevation of 850m to 4300m. The changing elevation gradients along mountain habitats act to control the distribution of butterflies at its ascending range. This study made on different periods in 2009 and 2012 brought a list of 114 species of butterflies from three different destinations of the northern side that included areas like Melamchi, Timbu (central-northern), Helambu (northern) Nakote (north-western) Panch Pokhari and adjoining region (north-eastern). The diversity of butterflies declined gradually above 3500m towards Panch Pokhari whereas species richness was noticed high at 900-2700 m from Melamchi to Helambu route including Nakote, Shermathan and Tarkyghyang. Ecotourism promotional activity can also be linked to the butterfly watch that includes rare and attractive species carrying high interest to the visiting tourists to this region. These tourists intend to watch, document and photograph these butterflies besides birds and other wildlife species. The supplementary information on these insects including other faunal components can be helpful to provide impressive knowledge to the visiting tourists to this part.

In spite of the importance of the "uruçu" bee as honey producer of excellent quality, as well, potential pollinator both in agricultural and natural ecosystems, mainly in North-eastern Brazil, just some information is found in literature about sources that such bees utilize to collect nectar and pollen. The identification of the plants visited by Melipona scutellaris was accomplished with base on the analysis of pollen types found in the honey samples collected every two months, from March 1997 to February 1998, in 15 colonies located in Catu, State of Bahia, Brazil (12°21'00"S, 38°22'40"W, 76 m of altitude). Qualitative and quantitative analysis of the pollen types were carried out determining the percentage and occurrence classes. Twenty-eight pollen types were found, being considered dominant pollen, the Eucalyptus spp. and Psidium sp. types and secondary pollen, Bauhinia sp., Caesalpinia sp. and Mimosa verrucata types. It was verified dominant pollen of Eucalyptus spp. in honeys produced in November/December 1997 and January/February 1998. The families Caesalpiniaceae (14%), Mimosaceae (25%) and Myrtaceae (56%) were the most represented in the pollen spectrum.

The Relationship

Is it possible to transform stone into a technological and innovative device? The meeting with one of the main stone transformers in Europe produced the intention of a disruptive operation that could affect the strategy of the whole company. A contagious singularity. By intertwining LEAN methodologies and the human-centric approach of design thinking, we mapped the value creation in the company activating a dialogue with the workers and the management, listening to people, asking for ambitions, discovering problems and the potential of production. This qualitative and quantitative analysis conducted with a multidisciplinary approach by designers, architects and marketing strategists allowed us to define a new method. We used it to design a platform that could let all the players express their potential to the maximum. This is how the group's research laboratory was born, with the aim of promoting the relationship between humans and stone through product innovation. With this goal, we coordinated the new team, developing technologies that would allow creating a more direct relationship between man and surface, making the stone reactive. The result was the first responsive kitchen ever.
