Spatiotemporal Evolution of Lakes Under Rapid Urbanization: a Case Study in Wuhan, China
water Article Spatiotemporal Evolution of Lakes under Rapid Urbanization: A Case Study in Wuhan, China Chao Wen 1, Qingming Zhan 1,* , De Zhan 2, Huang Zhao 2 and Chen Yang 3 1 School of Urban Design, Wuhan University, Wuhan 430072, China; [email protected] 2 China Construction Third Bureau Green Industry Investment Co., Ltd., Wuhan 430072, China; [email protected] (D.Z.); [email protected] (H.Z.) 3 College of Urban and Environmental Sciences, Peking University, Beijing 100871, China; [email protected] * Correspondence: [email protected]; Tel.: +86-139-956-686-39 Abstract: The impact of urbanization on lakes in the urban context has aroused continuous attention from the public. However, the long-term evolution of lakes in a certain megacity and the heterogeneity of the spatial relationship between related influencing factors and lake changes are rarely discussed. The evolution of 58 lakes in Wuhan, China from 1990 to 2019 was analyzed from three aspects of lake area, lake landscape, and lakefront ecology, respectively. The Multi-Scale Geographic Weighted Regression model (MGWR) was then used to analyze the impact of related influencing factors on lake area change. The investigation found that the total area of 58 lakes decreased by 15.3%. A worsening trend was found regarding lake landscape with the five landscape indexes of lakes dropping; in contrast, lakefront ecology saw a gradual recovery with variations in the remote sensing ecological index (RSEI) in the lakefront area. The MGWR regression results showed that, on the whole, the increase in Gross Domestic Product (GDP), RSEI in the lakefront area, precipitation, and humidity Citation: Wen, C.; Zhan, Q.; Zhan, contributed to lake restoration. -
Environmental Sustainability Strategies for Counteracting Erosion Effects and Soil Degradation in the Tatacoa Dessert

All rights reserved. www.arpnjournals.com ENVIRONMENTAL SUSTAINABILITY STRATEGIES FOR COUNTERACTING EROSION EFFECTS AND SOIL DEGRADATION IN THE TATACOA DESSERT Jennifer Katiusca Castro, Nestor Enrique Cerquera and Freddy Humberto Escobar Universidad Surcolombiana, Avenida Pastrana, Neiva, Huila, Colombia E-Mail: [email protected] ABSTRACT Three procedures aimed at establishing environmental sustainability strategies to counter the effects of erosion and soil degradation which contribute to improve productivity and biodiversity in the ecoregion of the Desert Tatacoa located in Neiva, Huila State, Colombia (South America). Phytogeographicalindex affinity of the Tatacoa Desert with other areas of tropical dry forest (bs-T) of Colombia were determined; the results allowed establishing the most suitable species living in this area for regreening work, promoting the conservation of native species of tropical dry forest in the Tatacoa Desert and knowing an existing phytogeographic affinity between other parts of the country to improve plant cover of all affected areas. Likewise, a model to estimate the gross value of agricultural production was built and found that the advance of the desertification process of this ecoregion has a significant reducing effect on soils’ production. Finally, a comparative analysis of respiratory activity and the mineralization rate of soil organic matter from different localities of the tropical dry forest (bs-T)of Huila state, which showed a different behavior for each treatment reflected as significant respiration changes and a mineralization rate whichprove that the potential degradation of soil microorganisms, for middle- and low organic matter content is low. -

Divergent Natural Selection with Gene Flow Along Major Environmental
Molecular Ecology (2012) doi: 10.1111/j.1365-294X.2012.05540.x Divergent natural selection with gene flow along major environmental gradients in Amazonia: insights from genome scans, population genetics and phylogeography of the characin fish Triportheus albus GEORGINA M. COOKE,*§ NING L. CHAO† and LUCIANO B. BEHEREGARAY*‡ *Molecular Ecology Laboratory, Department of Biological Sciences, Macquarie University, Sydney, NSW 2109, Australia, †Departamento de Cieˆncias Pesqueiras, Universidade Federal do Amazonas, Manaus, Brazil, ‡Molecular Ecology Lab, School of Biological Sciences, Flinders University, Adelaide, SA 5001, Australia Abstract The unparalleled diversity of tropical ecosystems like the Amazon Basin has been traditionally explained using spatial models within the context of climatic and geological history. Yet, it is adaptive genetic diversity that defines how species evolve and interact within an ecosystem. Here, we combine genome scans, population genetics and sequence-based phylogeographic analyses to examine spatial and ecological arrange- ments of selected and neutrally evolving regions of the genome of an Amazonian fish, Triportheus albus. Using a sampling design encompassing five major Amazonian rivers, three hydrochemical settings, 352 nuclear markers and two mitochondrial DNA genes, we assess the influence of environmental gradients as biodiversity drivers in Amazonia. We identify strong divergent natural selection with gene flow and isolation by environment across craton (black and clear colour)- and Andean (white colour)-derived water types. Furthermore, we find that heightened selection and population genetic structure present at the interface of these water types appears more powerful in generating diversity than the spatial arrangement of river systems and vicariant biogeographic history. The results from our study challenge assumptions about the origin and distribution of adaptive and neutral genetic diversity in tropical ecosystems. -

Abstract We report results of an ichthyological survey of the upper Rio Yuruá in southeastern Peru. Collections were made at low water (July-August, 2008) near the headwaters of the Brazilian Rio Juruá. This is the first of four expeditions to the Fitzcarrald Arch - an upland associated with the Miocene-Pliocene rise of the Peruvian Andes - with the goal of comparing the ichthyofauna across the headwaters of the largest tributary basins in the western Amazon (Ucayali, Juruá, Purús and Madeira). We recorded a total of 117 species in 28 families and 10 orders, with all species accompanied by tissue samples preserved in 100% ethanol for subsequent DNA analysis, and high-resolution digital images of voucher specimens with live color to facilitate accurate identification. From interviews with local fishers and comparisons with other ichthyological surveys of the region we estimate the actual diversity of fishes in the upper Juruá to exceed 200 species.

Abstract We present a checklist of the melittofauna from La Tatacoa Desert, Department of Huila, a remnant of highly disturbed tropical dry forest located in the upper valley of the Magdalena River. The list consists of 33 species in 20 genera of three families. The most abundant species was the emphorine bee Melitomella schwarzi (Michener, 1954), which accounted for 43% of the specimens collected. Exomalopsis (Phanomalopsis) trifasciata Brèthes, 1910 and Paratetrapedia connexa (Vachal, 1909) are newly recorded for Colombia.

Colombia Curriculum Guide 090916.Pmd
National Geographic describes Colombia as South America’s sleeping giant, awakening to its vast potential. “The Door of the Americas” offers guests a cornucopia of natural wonders alongside sleepy, authentic villages and vibrant, progressive cities. The diverse, tropical country of Colombia is a place where tourism is now booming, and the turmoil and unrest of guerrilla conflict are yesterday’s news. Today tourists find themselves in what seems to be the best of all destinations... panoramic beaches, jungle hiking trails, breathtaking volcanoes and waterfalls, deserts, adventure sports, unmatched flora and fauna, centuries old indigenous cultures, and an almost daily celebration of food, fashion and festivals. The warm temperatures of the lowlands contrast with the cool of the highlands and the freezing nights of the upper Andes. Colombia is as rich in both nature and natural resources as any place in the world. It passionately protects its unmatched wildlife, while warmly sharing its coffee, its emeralds, and its happiness with the world. It boasts as many animal species as any country on Earth, hosting more than 1,889 species of birds, 763 species of amphibians, 479 species of mammals, 571 species of reptiles, 3,533 species of fish, and a mind-blowing 30,436 species of plants. Yet Colombia is so much more than jaguars, sombreros and the legend of El Dorado. A TIME magazine cover story properly noted “The Colombian Comeback” by explaining its rise “from nearly failed state to emerging global player in less than a decade.” It is respected as “The Fashion Capital of Latin America,” “The Salsa Capital of the World,” the host of the world’s largest theater festival and the home of the world’s second largest carnival.
