Rock surfaces provide a challenging habitat for a broad diversity
of micro- or small-sized organisms. They interact with each other
forming complex communities as well with their substrate causing
biodeterioration of rock. Extreme fluctuation in light, temperature
and hydration are the main factors that determine the rock surface
habitats. The habitat includes epilithic organisms which thrive on
the surface without penetrating the rock, endolithic organisms
which live just beneath the surface using a thin layer of the rock
surface for protection against adverse conditions of the
environment (e.g. light protection, storage of water) and
chasmo-endolithic organisms which use fractures of the rock surface
for a more habitable environment. The book will provide an overview
of the various organismal groups, from prokaryotes to vascular
plants and arthropods, as well as survey organism-mediated
interactions with the rock surface. The latter include biogenic
weathering (biogeochemistry, state-of-the art imaging methods),
photosynthesis and nitrogen fixation at and inside the rock
surface.

An increasing population has put tremendous pressure on
agricultural productivity to fulfill the demands of human
consumption. Numerous agricultural activities and techniques have
been developed to raise annual crop production globally. While
agriculture has succeeded in enhancing the yearly crop
productivity, this achievement is at the cost of environmental
degradation by applying synthetic persistent substances, such as
industrial fertilizers, pesticides, herbicides, etc. Chemical
fertilizers are nearly as destructive as they are productive,
causing monocultures and consequences associated with elimination
of diversity, nutrient pollution as evidenced by algae blooms,
eutrophication, water quality issues, lower oxygen levels and
dangers to fish stocks. Therefore, the scientific approach to
maintain sustainable fertility in soil and plants is to switch over
to biofertilisers.Biofertilisers are compounds of organic matter
that are applied to crops for growth and health. Their constituent
micro-organisms interact in an ecofriendly manner with the soil,
root and seeds of plants, promoting the growth of micro-flora that
enhances soil fertility. They are known to play a number of vital
roles in soil fertility, crop productivity and production in
agriculture. Application of biofertilisers results in increased
mineral and water uptake, root development, vegetative growth and
nitrogen fixation. They liberate growth promoting substances and
vitamins and help to maintain soil fertility. They act as
antagonists and play a pivotal role in neutralising the soil borne
plant pathogens, thereby assisting in the bio-control of diseases.
Application of biofertilisers in lieu of synthetic fertilizers
could be the promising technique to raise agricultural productivity
without degrading the environmental quality. The present book
focuses on the latest research approaches and updates from the
microbiota ecosystem and their applications in agriculture
industry. It also highlights the great potential and possible
future of action of microbiota in the development of sustainable
agricultural systems.
This textbook aims to describe the role of minerals in plant life
cycle; how these nutrients are absorbed, distributed, stored; what
functions each mineral plays and the disorders that their excess or
absence may cause. From an agronomic perspective, such knowledge is
key to boost crop production and improve its quality, and it also
helps understand how to better manage fertilizers and prevent
environmental issues. The book has focus on tropical agriculture
and its specific demands, providing examples of major crops (such
as sugarcane, soybeans, coffee etc), silviculture and pasture
species.

This edited book is focused on SDG 15. This volume covers aspects
of species and ecosystem modeling in understanding the complexity
of ecological systems, restoration, protected area management, and
species conservation. The book follows a systematic and
situation-sensitive approach to discuss ecosystem and species
modeling tools, approaches, science, case studies, opportunities,
and gaps for enhancing conservation efforts, ensuring ecosystem
resilience, and addressing sustainability issues. The book
emphasizes on science, innovations, case studies, and strategic
relevance as main pillars of using ecosystem and species modeling
tools and implementing the outcomes and results. In addition, clear
conceptual frameworks, elaborated methodologies, and their
applications are included to support policy planning and
interventions to reduce and reverse human encroachment in
human-dominated natural ecosystems, their degradation, and loss of
important species and ecosystem services. Essential information
with a special focus on advances and opportunities in advancing the
implementation of results and outputs of the modeling tools,
challenges and constraints for addressing loss of ecosystem
services, designing and implementing sustainable landscape
restoration, environmental risk assessment, and finally
understanding policy implications and concerns for mainstreaming
modeling results in conservation planning and decision-making is
included in the book. Further topics include ultimate translational
value of modeling tools and efforts across transitional ecosystems
and species habitat to provide better evidence to influence the
nature-based solutions (NbS) and ecosystem health assessment using
Red List of Ecosystems (RLE). The emerging roles of integrative
socio-ecological as well as techno-cultural factors in promoting
the relevance of ecosystem and species modeling is one of the key
features of this book. This edited volume is of interest and useful
to researchers, students, scholars, policy makers, forest managers,
consultants, and policy makers in the fields of protected area
management, forest department, conservation, modeling, climate
change, and sustainability science, and also authors engaged in
IPBES, IPCC, and several other assessments.
This book highlights modern methods and strategies to improve
cereal crops in the era of climate change, presenting the latest
advances in plant molecular mapping and genome sequencing.
Spectacular achievements in the fields of molecular breeding,
transgenics and genomics in the last three decades have facilitated
revolutionary changes in cereal- crop-improvement strategies and
techniques. Since the genome sequencing of rice in 2002, the
genomes of over eight cereal crops have been sequenced and more are
to follow. This has made it possible to decipher the exact
nucleotide sequence and chromosomal positions of agroeconomic
genes. Most importantly, comparative genomics and
genotyping-by-sequencing have opened up new vistas for exploring
available biodiversity, particularly of wild crop relatives, for
identifying useful donor genes.
Agriculture is considered as a backbone of developing nations as it
caters the needs of the people, directly or indirectly. The global
agriculture currently faces enormous challenges like land
degradation and reduced soil fertility, shrinking of land, low
production yield, water accessibility and a dearth of labor due to
evacuation of individuals from farming. Besides, the global
population increases at an exponential rate and it is predicted
that the global population will be 9 billion by 2050 that in turn
leads to food crisis in near future. Although, green revolution
revolutionizes the agriculture sector by enhancing the yield but it
was not considered as a sustainable approach. Exorbitant use of
chemical fertilizers and pesticides to boost the crop yield is
definitely not a convenient approach for agriculture sustainability
in the light of the fact that these chemical fertilizers are
considered as double-edged sword, which on one hand enhance the
crop yield but at the same time possess deleterious effect on the
soil microflora and thus declines its fertility. Besides, it cause
irreversible damage to the soil texture and disrupts the
equilibrium in the food chain across ecosystem, which might in turn
lead to genetic mutations in future generations of consumers. Thus,
the increased dependence on fabricated agricultural additives
during and post green revolution has generated serious issues
pertaining to sustainability, environmental impact and health
hazards. Therefore, nano-biotechnology has emerged as a promising
tool to tackle the above problems especially in the agriculture
sector. Nano-agribusiness is an emerged field to enhance crop
yield, rejuvenate soil health, provide precision farming and
stimulate plant growth. Nano-biotechnology is an essential tool in
modern agriculture and is considered as a primary economic driver
in near future. It is evaluated that joining of cutting edge
nanotechnology in agribusiness would push the worldwide monetary
development to approximately US$ 3.4 trillion by 2020 which clearly
indicates that how agri-nanobiotechnology plays a pivotal role in
the agricultural sector, without any negative impact on the
environment and other regulatory issues of biosafety.
Agri-nanobiotechnology is an innovative green technology, which
provides the solution to global food security, sustainability and
climate change. The current book is presenting the role of
nano-biotechnology in modern agriculture and how it plays a pivotal
role to boost the agri-business.
Traditional methods in synthetic chemistry produce chemical waste
and byproducts, yield smaller desired products, and generate toxic
chemical substances, but the past two centuries have seen
consistent, greener improvements in organic synthesis and
transformations. These improvements have contributed to substance
handling efficiency by using green-engineered forerunners like
sustainable techniques, green processes, eco-friendly catalysis,
and have minimized energy consumption, reduced potential waste,
improved desired product yields, and avoided toxic organic
precursors or solvents in organic synthesis. Green synthesis has
the potential to have a major ecological and monetary impact on
modern pharmaceutical R&D and organic chemistry fields. This
book presents a broad scope of green techniques for medicinal,
analytical, environmental, and organic chemistry applications. It
presents an accessible overview of new innovations in the field,
dissecting the highlights and green chemistry attributes of
approaches to green synthesis, and provides cases to exhibit
applications to pharmaceutical and organic chemistry. Although
daily chemical processes are a major part of the sustainable
development of pharmaceuticals and industrial products, the
resulting environmental pollution of these processes is of
worldwide concern. This edition discusses green chemistry
techniques and sustainable processes involved in synthetic organic
chemistry, natural products, drug syntheses, as well various useful
industrial applications.
Fungi are an understudied, biotechnologically valuable group of
organisms. Due to their immense range of habitats, and the
consequent need to compete against a diverse array of other fungi,
bacteria, and animals, fungi have developed numerous survival
mechanisms. However, besides their major basic positive role in the
cycling of minerals, organic matter and mobilizing insoluble
nutrients, fungi have other beneficial impacts: they are considered
good sources of food and active agents for a number of industrial
processes involving fermentation mechanisms as in the bread, wine
and beer industry. A number of fungi also produce biologically
important metabolites such as enzymes, vitamins, antibiotics and
several products of important pharmaceutical use; still others are
involved in the production of single cell proteins. The economic
value of these marked positive activities has been estimated as
approximating to trillions of US dollars. The unique attributes of
fungi thus herald great promise for their application in
biotechnology and industry. Since ancient Egyptians mentioned in
their medical prescriptions how they can use green molds in curing
wounds as the obvious historical uses of penicillin, fungi can be
grown with relative ease, making production at scale viable. The
search for fungal biodiversity, and the construction of a living
fungi collection, both have incredible economic potential in
locating organisms with novel industrial uses that will lead to
novel products. Fungi have provided the world with penicillin,
lovastatin, and other globally significant medicines, and they
remain an untapped resource with enormous industrial potential.
Volume 1 of Industrially Important Fungi for Sustainable
Development provides an overview to understanding fungal diversity
from diverse habitats and their industrial application for future
sustainability. It encompasses current advanced knowledge of fungal
communities and their potential biotechnological applications in
industry and allied sectors. The book will be useful to scientists,
researchers, and students of microbiology, biotechnology,
agriculture, molecular biology, and environmental biology.
The term 'botanical aesthetics' refers to the visual and embodied
modes which inform the perception, understanding, and appreciation
of plant life. Green Sense is an interdisciplinary study of human
aesthetic relationships to wild plants and the 'cultures of flora'
that may characterise a region. The book explores botanical
aesthetics through a study of the South-West region of Western
Australia; a biodiversity 'hotspot' of international standing.
Through a diverse range of materials, approaches, and perspectives,
this title points to the interplay of values informing cultures of
flora-from visual aesthetics and scientific knowledges, to embodied
appreciations and sensory entanglements. The book provides a model
for better understanding human relationships to wild plants, and
offers an intriguing journey through science, poetry, philosophy,
ethnography, Indigenous Australian knowledges, regional tourism,
and memory studies. John Charles Ryan is a Postdoctoral Research
Fellow in the Centre for Research in Entertainment, Arts,
Technology, Education, and Communications (CREATEC) and the School
of Communications and Arts at Edith Cowan University in Mount
Lawley, Western Australia. Prior to his appointment, he completed a
research doctorate with a focus on ecocultural studies of
Australian biodiversity and creative responses to place. In 2003,
he was awarded a Master of Arts degree in Values and the
Environment (MAVE) from the University of Lancaster, UK. With the
artist Ellen Hickman, he is co-author of Two with Nature, published
in 2012. He is also a contributor to a forthcoming collection
Fremantle Poets 3: Performance Poets. His ecocultural research has
appeared in Continuum; Australian Humanities Review; Australian
Garden History; Nature and Culture; New Scholar; and
Transformations. Green Sense will appeal to readers interested in
the sensory and embodied aspects of human relationships to plants.
Advances in Phytonanotechnology: From Synthesis to Application
guides readers through various applications of nanomaterials on
plants by presenting the latest research related to nanotechnology
and nanomaterials on plant systems. The book focuses on the effects
of these applications on plant morphology, physiology,
biochemistry, ecology and genetics. Sections cover the impact on
plant yield, techniques, a review of positive and negative impacts,
and an overview of current policies regarding the use of
nanotechnology on plants. Additionally, the book offers insights
into the appropriate application of nanoscience to plants and crops
for improved outcome and an exploration of their bioavailability
and toxicity in the environment.
This two-volume book, Biomolecules and Pharmacology of Medicinal
Plants, will be a valuable desk reference book on bioactives and
pharmacology of medicinal plants. Listing the medicinal plants by
species, each of these 77 chapters detail the plants' bioactive
phytocompounds and their chemical structures along with their
pharmacological activities and properties. These include the
plants' antiviral, antibacterial, antifungal, antioxidant,
anticancer, anti-inflammatory, anti-diabetic, hepatoprotective,
cardioprotective, and nephroprotective properties. Bioactive
compounds typically occur in small amounts, and they have more
subtle effects than nutrients. Bioactive compounds influence
cellular activities that modify the risk of disease and cure and
alleviate disease symptoms. These compounds can act as
antioxidants, enzyme inhibitors and inducers, inhibitors of
receptor activities, and inducers and inhibitors of gene expression
among other actions. A wide array of biological activities and
potential health benefits of medicinal plants have been reported,
which include antiviral, antimicrobial, antioxidant, anti-cancer,
anti-inflammatory, antidiabetic properties as well as protective
effects on the liver, kidney, heart, and nervous system. The
volumes will be a must-have reference for pharmacy institutes and
pharmacy professors, phytochemists and research scholars, botanists
working with medicinal plants, and postgraduate students of
pharmacy and medicine round the world. The comprehensive
information presented here provides an invaluable source to aid in
the development of new drugs.
