Understanding the extent to which ecological divergence is repeatable is essential for predicting responses of biodiversity to environmental change. Here we test the predictability of evolution, from genotype to phenotype, by studying parallel evolution in a salmonid fish, Arctic charr (Salvelinus alpinus), across eleven replicate sympatric ecotype pairs (benthivorous-planktivorous and planktivorous-piscivorous) and two evolutionary lineages. We found considerable variability in eco-morphological divergence, with several traits related to foraging (eye diameter, pectoral fin length) being highly parallel even across lineages. This suggests repeated and predictable adaptation to environment. Consistent with ancestral genetic variation, hundreds of loci were associated with ecotype divergence within lineages of which eight were shared across lineages. This shared genetic variation was maintained despite variation in evolutionary histories, ranging from postglacial divergence in sympatry (ca. 10-15kya) to pre-glacial divergence (ca. 20-40kya) with postglacial secondary contact. Transcriptome-wide gene expression (44,102 genes) was highly parallel across replicates, involved biological processes characteristic of ecotype morphology and physiology, and revealed parallelism at the level of regulatory networks. This expression divergence was not only plastic but in part genetically controlled by parallel cis-eQTL. Lastly, we found that the magnitude of phenotypic divergence was largely correlated with the genetic differentiation and gene expression divergence. In contrast, the direction of phenotypic change was mostly determined by the interplay of adaptive genetic variation, gene expression, and ecosystem size. Ecosystem size further explained variation in putatively adaptive, ecotype-associated genomic patterns within and across lineages, highlighting the role of environmental variation and stochasticity in parallel evolution. Together, our findings demonstrate the parallel evolution of eco-morphology and gene expression within and across evolutionary lineages, which is controlled by the interplay of environmental stochasticity and evolutionary contingencies, largely overcoming variable evolutionary histories and genomic backgrounds.
Broad academic training in the sciences and math in combination with specialized training within the NRC concentrations prepare students for professional employment in state, federal, and non-profit conservation organizations, as well as environmental consulting firms and the green industry, or if students choose, to continue to graduate training. There are a wide variety of careers in natural resources conservation, including:
professional foresters and plant ecologists; wildlife and fisheries technicians and biologists; park managers and rangers;naturalists, environmental educators and outdoor recreation specialists; watershed scientists; water and landuse planners; environmental lawyers, policy-makers and conservation law enforcement officers.
The Natural Resources Conservation (NRC) major provides students with rigorous academic training in the natural, conservation, and social sciences with hands-on field skills and field experiences. Students in the Natural Resources Conservation major focus on one of the following six concentrations:
Students then take specialized courses designed to provide them with the knowledge and skills necessary for entry-level employment, graduate training, and professional certification in a conservation concentration. Hands-on field skills integrated into the coursework and field experiences from summer jobs, internships, and cooperative education positions are essential components of the professional training in natural resources conservation.

Along with the eco-friendly benefits, there are also personal benefits that coincide with using all-natural products. Plastics, for example, are known to have BPA, lead, and other harmful chemicals that can cause many different illnesses and diseases in both children and adults. For adults, the risks include diabetes, heart disease, autoimmune diseases, and reproductive system abnormalities. For children, it can cause premature puberty, diabetes, stunted growth, and autoimmune disorders. Eco-friendly, all natural products ensure safety from all dangerous chemicals, and allows families to avoid risky additives that can cause any of these issues. Using eco-friendly products improves quality of life in terms of mortality, age, diseases, and illnesses. They ensure the safety of families and the planet.
House Décor: A lot of businesses are beginning to create eco-friendly home décor that encourage all natural decorations. Some of the most practical (and stylish!) options for all natural home décor are:
The EIA reports that the U.S. residential sector consumed 4.65 trillion cubic feet of natural gas in 2021.3 We divided that number by the total number of households in the United States (122,354,2194) to determine that the average home consumed 38,004 cubic feet of natural gas in 2021. At an average cost of $15.19 per thousand square feet for natural gas in the six months ending in June 2022, we estimate the average household spends $577.19 on natural gas per year.
Biological stains are generally used to add color to animal and plant tissues, microbes and spores to make them optically distinct. This technique of visual labeling is known as staining. Before synthetic dyes came into use, natural stains were already available and were used for various purposes. However, their use was limited, and to compensate for their shortcomings, superior and more effective synthetic dyes are still in use. They are superior in terms of rapidity and versatility and are widely available at an economical price.[2] However, most synthetic stains are carcinogenic while others may cause hypersensitivity reactions on long-term exposures. Their toxic properties also pose a problem in their safe disposal. This consequently led to the development of stains which are not only environmentally safe but are also harmless.[3] The most sought nuclear stain, hematoxylin, is obtained from the Mexican tree Haematoxylon campechianum; it is an example of a natural dye which is widely used in histochemistry. On the contrary, its counterstain eosin is a synthetic dye which belongs to the xanthene group.[2] These dyes are not only efficient but also has deleterious effects which are hazardous to human and animal health. With the increasing awareness of a green earth, it is advisable to use more of environment-friendly and biodegradable material. This can be effectively achieved by the use of natural dyes obtained from plants and other natural sources. Moreover, as many developing countries can no longer afford the ever-increasing cost of synthetic dyes, the use of cost-effective and naturally occurring dyes from plants is always a better option.[4]
Although you cannot put a value on all the ways the natural world enriches our lives, there are many tangible benefits to living in a world with strong and healthy ecosystems. We have a stronger economy, diverse food products, and advancements in medical research as a result of wildlife and natural ecosystems.
1. Provisioning ServicesWhen people are asked to identify a service provided by nature, most think of food. Fruits, vegetables, trees, fish, and livestock are available to us as direct products of ecosystems. A provisioning service is any type of benefit to people that can be extracted from nature. Along with food, other types of provisioning services include drinking water, timber, wood fuel, natural gas, oils, plants that can be made into clothes and other materials, and medicinal benefits.
2. Regulating ServicesEcosystems provide many of the basic services that make life possible for people. Plants clean air and filter water, bacteria decompose wastes, bees pollinate flowers, and tree roots hold soil in place to prevent erosion. All these processes work together to make ecosystems clean, sustainable, functional, and resilient to change. A regulating service is the benefit provided by ecosystem processes that moderate natural phenomena. Regulating services include pollination, decomposition, water purification, erosion and flood control, and carbon storage and climate regulation.
3. Cultural ServicesAs we interact and alter nature, the natural world has in turn altered us. It has guided our cultural, intellectual, and social development by being a constant force present in our lives. The importance of ecosystems to the human mind can be traced back to the beginning of mankind with ancient civilizations drawing pictures of animals, plants, and weather patterns on cave walls. A cultural service is a non-material benefit that contributes to the development and cultural advancement of people, including how ecosystems play a role in local, national, and global cultures; the building of knowledge and the spreading of ideas; creativity born from interactions with nature (music, art, architecture); and recreation. 2ff7e9595c
