The Factors for the Extinction of Jaguars and Cougars in El Salvador

Human population increase, intensified land use and attitudes to wildlife, as well as habitat losses, hunting and pollution have devastated the global biodiversity, even in ecological “hotspots” such as Central America.

Extinction of Jaguars
Of all wild mammal species, half have declining populations and one quarter is threatened with extinction. Large carnivores are particularly affected, due to low population densities, human fear and attitudes, physical conflict, their mobility and requirement of large tracts of land and wide ranging prey species, and consequent difficulties of conservation.

Consequently, the creation of reserves may be fruitless, due to land use conflicts with other pressing requirements, such as urbanization and agriculture, and the difficulty of restricting large carnivores to land inside the reserves.

Infill Development: an Approach to the Optimal and Intelligent Development of Cities - Case Study: Zone 8 of Tabriz

Today, about 50% of the world population or three and a half billion live in cities but it is expected that by 2050, the urban population of the world increases by 84%; namely, 3.6 billion people.

Development of Cities
Although population growth is the primary cause of the spread of cities, the same irrational distribution or horizontal expansion and new construction around the city caused socio-economic damages and destruction of environmental resources in the cities and surroundings.

Due to a substantial effect of the form of a city on its stability, it is necessary to know study and understand its dimensions and guide it to achieve sustainable development. After 1970s and the World War II, severe reactions to uncontrolled growth of cities began.

Simulated Impact of Intensification of Irrigation on Indian Monsoon Rainfall and Surface Fluxes

Agriculture, human health, major weather and climate phenomenon are impacted by climate change. Indian subcontinent is home to one-sixth of world population, where the Indian summer monsoon rainfall (ISMR) is important for irrigation activities.

Indian Monsoon Rainfall
Within India, there is also evidence that intensive irrigation has led to changes in monsoon rainfall patterns with Lohar and Pal reporting that doubling of the area covered by summer paddy crops in West Bengal is a possible cause for mean monthly rainfall from 1983-1992, less than half that observed from 1973-1982.

The two-dimensional numerical simulations indicate that wetter soils along the coast reduce the temperature gradient between the land and the sea, hence reducing the intensity of sea breeze circulations and, therefore, lead to diminished pre-monsoon rainfall.

Renovated Breeding Habitat use in Wild & Captive-bred Populations of an Endangered Desert Pupfish

Habitat loss is a persistent threat for endangered species, with both natural and human factors contributing to the devastating fragmentation of natural environments. In extreme cases, this fragmentation can result in species having little to no natural habitat remaining in which to repopulate.

Desert Pupfish
Attempts to combat this growing phenomenon have emerged in the form of rebuilding or expanding natural habitats in order to facilitate population re-growth. However, the success of such projects has been limited, and as a result, habitat restoration alone is considered an unreliable method of mitigating species loss.

This is largely due to restoration attempts facing a myriad of constraints that can impact both short and longterm progress, and a large proportion of restoration projects being deemed insufficient in terms of increasing population size.

THIS BACTERIA CAN REDUCE SODIUM LEVELS IN WASTE WATER

Water is the most vital resource for all kinds of life, but it is being adversely affected both quantitatively and qualitatively. Today, most of the rivers receive millions of litre of sewage and industrial effluents containing varying characteristics from simple nutrients to highly toxic substances.

Because of increasing population and industrial developments, a huge amount of wastewater is discharged to the environment above the level that the nature can eliminate. One of the most important industrial activities in India with its magnitude of economy is the textile industry.

Textile industry discharges a complex huge volume of waste water containing various chemicals used in dyeing, printing and finishing processes. The effluent generated in different steps or processes is well beyond the standard and thus it is highly polluted and dangerous

A Negative Binomial with a Non-Homogenous Gamma Distributed Mean for Robustifying Pseudo R2 Regression Values of Immature Vector and Nuisance Mosquito

Automobile tires discarded in undeveloped land plots near anthropogenic and animal habitations are a health hazard because they can support an immature population of vector mosquitoes.

Nuisance Mosquito
These mosquitoes may transmit several zoonotic arboviral diseases. Hillsborough County, Florida has recorded anthropogenic cases of locally-acquired West Nile virus, Eastern equine encephalitis, and La Crosse encephalitis in the past few years.

Unfortunately, there are no means to locate waste tires dumped near georeferenced human dwellings besides ground-based searches. Thus, location techniques for waste tires that conserve limited funds and human resources are needed for arboviral disease prevention via tire removal in Hillsborough County.

Assessment of Ambient Air Quality with Special Reference to NO2 in the Waste Dump Site at Osisoma Ngwa LGA, Nigeria

Air pollution is woven throughout the fabric of our modern life. Pollution problems began with the growth of cities and population and their related water, industrial and disposal needs. With the increase of urbanization man began to intrude on the beautiful, balanced mechanism of the atmosphere.

Ambient Air Quality
Nitrogen oxides include chiefly NO, NO2 and HNO3 mostly released by automobiles, power-plants and chemical from industries. The industries manufacturing HNO3 and other chemicals and the automobile exhausts are the chief source of the Nitric Oxide (NO) gas to the environment.

At high temperature, combustion of gasoline produces this gas. A number of chemical reactions serially convert a large amount of NO to more toxic NO2 in the atmosphere. NO is responsible for the several photochemical reactions in the atmosphere, particularly in the formation of several secondary pollutants like PAN, O3, Carbonyl compounds, etc.,

Facies Study of the Halang Formation Turbidites in Cibalung Area, Cimanggu District, Cilacap Regency, Central Java

Well preserved outcrops of the Late Miocene Early Pliocene turbidites Halang formation exposed around Cibalung area in Central Java. A continuous exposure of the Halang Formation found along Cimindi and Cikawung River are considered highly representative for detailed facies studies (Irawan).

Halang Formation Turbidites
However, it has not been extensively studied, until now. This study focuses on the sedimentation structure, vertical and lateral sedimentary facies association to determine the depositional environment of the Halang formation.

The study area lies on the Bogor Zone which is defined as a 30 km-long anticlinorium stretching in east-west trend. Anticlinorium stretching from West to East. Based on the works from Kastowo and Suwarna.

Fold-thrust Style and Fluid Reservoir Potential of Eocene Sakesar Limestone

Surghar Range is the outer most fold-and-thrust belt of the sub- Himalayas making the easternmost extension of the Tran-Indus ranges (TIR) bifurcated by the KaIabagh fault system from the western Salt Range of North Pakistan.

Eocene Sakesar Limestone
The range follows east-west structural trend along the sothern margin of the Kohat plateau and switches to north-south trend along the easternmost flank of Bannu Basin. Along the range front the non-outcropping Permian to Eocene rocks underneath the Kohat and Bannu Basin are exposed at surface.

The range displays arcuate structural style in plan and exhibits distinct mountain forefront geometries along its map trace. It is characterized by south facing structures along its east-west trending segment. Whereas the north-south trending segment of the range is dominated east vergent fold-thrust assemblages.

Seed Germination and Seedling Survival Percentage of Shorea robusta

The greater parts of the forest area of Similipal Biosphere Reserve (SBR) are covered by moist deciduous forests, where Shorea robusta dominating in the overstorey layer. It is not only a dominant overstorey (tree) species of moist deciduous forest covers of Similipal but also one of the major species of tropical moist deciduous forests of Odisha and India.

Shorea robusta
In such forests the seeds of Sal have been the subject of great interest for the forest researchers and plantation managers as they are categorized under recalcitrant seeds and possess a very short period of viability.

Though the plants produce flowers and fruits luxuriantly in the plains and foothills, its overall natural regeneration is very poor. As a result, the Sal forests are becoming reduced its size gradually. Even worse is the fact that it exhibits largescale mortality or die-back at the seedling stage due to drought.

Thermodynamics Reason for Dying of Urmia Lake, This is not Just an Aral Syndrome!

Urmia Lake is located in a closed basin between both the West and Eastern Azerbaijan provinces in the north-west of Iran (37°4’-38°17’ N and 45°-46°E). The shape of the lake can be seen as a semi-triangle with a maximum length of 135 km and the surface area is between 5000 and 6000 km2.

Dying of Urmia Lake
The lake in its current form can be seen in Figure 1. Urmia Lake is one of the most saline lakes, as well as the second largest, in the world and the largest lake on the Iranian Plateau. It is considered as a UNESCO biosphere and a Ramsar wetland because the lake has a unique eco-system.

Surface flow, direct rainfall, and groundwater create the majority of the sources for the lake. In the Urmia lake basin, there are twenty-one permanents and thirty-nine episodic rivers. Among the thirteen main rivers, Zarrinerood is the largest river with total annual discharge value of about 2 × 109 m3.

A Multistage Technique to Minimize Overestimations of Slope Susceptibility at Large Spatial Scales

Rainfall induced landslides are one of the most frequent natural hazards on slanted terrains. They usually result in great economic losses and fatalities globally. Worldwide at least 32,322 deaths between 2004 and 2010 have been reported and in the United States alone, landslides cause $1-2 billion in damages and more than 25 fatalities in average each year.

Multistage Technique to Minimize Overestimations
Understanding, mapping, modeling and preventing the aftermath of these devastating events represents an important scientific and operational endeavor.The term “Landslide” describes the downward and outward movement of slope-forming materials that include rock, earth, and debris or a combination of these.

Although landslides are considered to be dependent on the complex interaction of several static and dynamic factors slope angle has great influence on the susceptibility of a slope to sliding. Increased slope angle usually correlates to increased likelihood of failure even if the material distribution on the slope is uniform and isotropic.

The Impact of the Natural Hazard Flooding in East Part of Croatia-Reducing Possible Consequences

In recent decades we have witnessed more frequent and stronger weather and climate extremes: more frequent heat waves, heavy precipitation but also prolonged drought and strong winds. This trend was significant not only for Croatia but also the whole world, and it is a result of global climate changes.

Natural Hazard Flooding
This study highlights the potential health exposure risks (communicable diseases occurrence and spread) according to which recovery phase activities were taken, as well as the synoptic analysis of the weather situation which describes the terms and processes that led to a record rain fall and flooding of massive proportions.

During a weather front that passed over north-east of Croatia on May 2014, extreme rainfall events were triggered causing several severe flash floods. Ground and altitude synoptic analysis of weather situation describes the terms and processes that led to extreme rainfall.

Ethnobotany and Ethnopharmacology, the First Step towards Bioprospecting

The Journal of Biodiversity, Bioprospecting and Development is a good context to evaluate from a scientific point of view the importance of biodiversity and its use and effects on social development, including economic development. Humans have always used natural resources because they are part of the environment and inevitably interact with it.

Bioprospecting
Foods, medicines, home all have their origin in nature. In the evolutionary process of human society, the use of natural resources based on direct experience became a use based first on cultural tradition, and later on scientific research and evidence. It is important to understand the role of ‘ethno’ sciences and other social sciences for the development of human societies, as well as the significance of science, which is reflected in scientific publications.

The conflict of interests between various parties involved in bioprospecting has already started, and social actors have a relevant role because ethno sciences are involved. We present the problem in this editorial article, in the best framework: this journal.
