Purification Of Water

The high Andean wetlands of Peru provide not only the well-known ecosystem services such as water storage, flood mitigation, erosion control, and purification of water, but are also a source of income for local economies (as fodder), have medicinal properties, are a source of food, contribute to the development of ecotourism among many other uses. Economic and population growth have already damaged many parts of the high Andean wetlands including their rich flora. In order to promote the conservation of its diversity and unique flora, this study conducted extensive botanical explorations to identify and map the floristic composition of the high Andean wetlands of La Libertad, Peru, as well as their influence on local communities. The authors conducted explorations taking taxonomic, biogeographic and ethno biological data of the flora species as well as their therapeutic and economic botany. The study identified 64 species of flora distributed in 46 genera and 27 families including Asteraceae (with 8 species), Juncaceae (with 7 species), Poaceae (with 6 species), Cyperaceae (with 5 species), Licopodiaceae and Rosaceae (with 4 species each), Apiaceae, Gentianaceae, Orobanchaceae and Sphagnaceae (with 3 species each) and Poligonaceae (with 2 species). With reference to economic botany, it was found that 32.8% of species constitute resources with a very good economic benefit. The study concludes that it is imperative to take actions to protect the high Andean wetlands as they are ecosystems with great biodiversity. This study contribution expects to raise concerns regarding the increasing impact of economic and population growth on the loss of not only natural habitats but species as well. Conservation efforts will help protect the heritage of the Andes wetlands for future generations.

Montane forests of southern Mexico have been severely fragmented and their structure and floristic composition have been altered because of traditional agriculture and population growth. In extensive areas of Chiapas, forest restoration is not only an urgent need, but it also represents a viable option for the recovery of products and services that could be used in the future in a sustainable way. Forest restoration should be based upon the understanding of basic ecological processes followed by the design of appropriate practices, and taking into account economic and social issues that may guide an adaptive approach of the action programs. Research, development, and outreach experiences spanning more than a decade lead us to suggest models for some of the ecological, technical, and social issues underlying the recovery, conservation, and rational use of forest resources

Sea daffodil (Pancratium maritimum L.) is the only known Pancratium species that is naturally grown in Turkey, belongs to the Amaryllidaceae family, a group of monocotyledons. P. maritimum L. is a perennial Mediterranean plant. It grows naturally in the sandy coasts of Tukey. P. maritimum, which finds a living area right next to the sea, is a drought-tolerant plant that is exposed to direct sea breezes and strong radiation with constantly high air humidity. The roots of modified stem bulbs sink down to 80 cm in the sand. The self-fertilized Sea daffodil is flowering in June-October. It was reported that P. maritimum is one of the rare and endangered plants of Turkey because of usage natural habitats of sand lilies as coasts, excessive collection flowers and bulbs. The landscape value of this geophyte is high with white and fragrant flowers. In addition to their potential usage as ornamental plants, their usage in pharmacology especially in the treatment of cancer, Alzheimer and AIDS due to the medical properties of the modified stems and in other related industries increases their importance. It is also important to protect this genetic resource for biodiversity. In this review, botanical, biological and medicinal properties of P. maritimum as well as potential usage as ornamental plant, threats and importance of this species for Turkey were given and discussed.

Environmental Limits

AbstractEnvironmental limits of animal life are invariably revised upwards when the animals themselves are investigated in their natural habitats. Here we report results of a scientific mountaineering expedition to survey the high-altitude rodent fauna of Volcán Llullaillaco in the Puna de Atacama of northern Chile, an effort motivated by video documentation of mice (genus Phyllotis) at a record altitude of 6205 m. Among numerous trapping records at altitudes >5000 m, we captured a specimen of the yellow-rumped leaf-eared mouse (Phyllotis xanthopygus rupestris) on the very summit of Llullaillaco at 6739 m. This summit specimen represents an altitudinal world record for mammals, far surpassing all specimen-based records from the Himalayas and elsewhere in the Andes. This discovery suggests that we may have generally underestimated the altitudinal range limits and physiological tolerances of small mammals simply because the world’s highest summits remain relatively unexplored by biologists.

Areas near human disturbance may become prey refugia when predators avoid human activities more than their prey leading to decreased predation rates and/or increased prey population growth. Alberta’s Athabasca oil sands region (AOSR) is home to moose (Alces alces) and wolf (Canis lupus) populations and is characterized by extensive human disturbance including open pit mines, tailings ponds and industrial facilities. We examined the extent to which moose could be released from predation near Alberta’s Athabasca oil sands due to wolf avoidance of mining infrastructure. Using moose and wolves GPS telemetry, we compared the use of natural habitats and distance to mining features to the availability of these variables. We split mining features into high human-use facilities and low human-use pit mines and tailings ponds. We binned distance to mining features variables into distance buffers covering the range of moose home range diameters resulting in buffers of < 2.5 km, 2.5-5 km and 5-10 km. Moose models included an interaction between distance to mining features buffers and the distribution of wolves to assess whether moose exposure to wolves varies with proximity to human activity. We compared a habitat model including forest cover type, streams and rivers to a disturbance model using AIC. The model fitting habitat and distance to facilities was top-ranked for both species. Moose selection for areas near facilities was higher than wolves. Wolves avoided areas within 10 and 5 km of facilities but exhibited an equivocal response within 2.5 km. Moose exposure to wolves increased with distance to mines indicating that use of areas in proximity to human disturbance releases moose from predation by wolves. Human induced prey refugia could increase moose population growth and increase human-moose conflict. Additionally, moose dispersal out of the refuge areas could produce subsequent increases in the wolf population.

Sideritis scardica (S. scardica) is an endemic medicinal species of the Central Balkan Peninsula. The aerial parts are traditionally used in folk medicine and, therefore, have been collected extensively from natural habitats. Overexploitation in combination with climate change has resulted in severely fragmented populations. In this context, the purpose of this study was to access the abundance and phenotypic diversity of S. scardica populations in relation to plant community structure and environmental and anthropogenic factors in six mountainous areas of Northern Greece. For this reason, the floristic composition and diversity was determined by accessing the number of plant species, number of individuals per plant species, and plant cover in each study area. In addition, the soil properties of the studied areas were determined and the phenotypic diversity of S. scardica populations was accessed through the imaging of leaf and inflorescence main characteristics. As a result, 141 plant species were identified in all studied areas, while the floristic composition clearly distinguished the North-Central from the North-Eastern studied areas. S. scardica was the predominant species in the habitats where the presence of forbs was favored, while a high presence of graminoid and shrub species in the study areas depressed its presence. A high coefficient of variations was recorded among the six populations, varying from 12.2%–29.2% and 13.3%–43.1% for inflorescence and leaf traits.

Abstract: This study was developed in Ibitipoca State Park (ISP), a mountainous massif that stands out in the Serra da Mantiqueira, in the Southeastern Region of Brazil. The vegetation is represented by a phytophysiognomic mosaic where areas of campos rupestres interspersed with cloud dwarf forests predominate, at altitudes of 1100 to 1700 m.s.m. The cloud dwarf forests exist in narrow altitude belts on the mountain peaks, immersed in a layer of clouds. They form a peculiar landscape high in the mountains by the short stature of the arboreal elements and richness of lichens and bryophytes, which develop under constant condensation of humidity, low temperatures, and frequent winds. The objective of the present work was to determine the floristic composition and phytogeography of the cloud dwarf forests of ISP. Twelve monthly campaigns were conducted to collect botanical material during the years 2014 and 2015. The collected material was deposited in the collection of the CESJ Herbarium. A total of 372 species, 209 genera, and 73 families of phanerogams were found. The richest families were Orchidaceae (84 spp.), Asteraceae (39 spp.), and Melastomataceae (21 spp). The genera with the greatest wealth were Leandra (09 spp.), Epidendrum (09 spp.), Pleurothallis (09 spp.), Mikania (07 spp.), and Miconia (07 spp). The arboreal habit was predominant with 103 species (27.7%), followed by 83 shrubs (22.3%), 82 epiphytic herbs (22%), 80 terrestrial herbs (21.5%), and 23 lianas (6.5%). The floristic composition presents elements typical of altitude vegetation, including species of campos rupestres and high epiphytes richness, especially of the families Orchidaceae and Bromeliaceae. The genera with tropical distribution represent 86.5%, whereas the temperate elements represent 13.5% of the total. The cloud dwarf forests presented similarity, at the family and gender levels, with the upper montane forests of the Andes, besides phytogeographic characteristics that allow to associate them to a transition environment between the campos rupestres and the upper montane forests of the Southeast Region of Brazil.
