Abstract
Ecology
is the study of the interaction between organisms and their environment. To
fulfill the food requirements of increasing population, human activities are
affecting the ecosystem. It has never been extra important to comprehend what
regulates the dispersal and richness of species, how they intract with each
other and their environment, and how biodiversity rejoins to threats by
change in climate, invasive species, over-exploitation and destruction of
habitat.
??????????? Issues
arising due to climate change, understanding the ecosystem, and the measures
required to sustain Earth's life-support systems has become progressively
important. In this evolutionary process, human activities have played a
prominent role, and those who study vegetation cannot afford to neglect this
aspect.
??????????? Conversion
of natural habitats into industrial and agricultural landscapes, and finally
into tainted land, is the major influence of humans on the natural
environment, posing a great threat to biodiversity. Restoration of ecosystem
is an emerging discipline which provides a more suite of tools for the
recovery of degraded lands. Restoration of ecology offers a crucial
accompaniment to nature reserves as a way for the preservation of
biodiversity. An unified understanding of human population growth and changes
in agricultural practices with natural recovery processes and restoration
ecology offers hope for the future of the environment. Even though ecologists
have documented the role of history and historical legacy concept in
determining present-day ecological systems, few international conservation
assessments consider time scales more than 50 years. Conservation biology is
prearranged management of natural resources and natural balance retention,
diversity and evolutionary processes in the environment. Conservation
strategies in a rapidly changing world need to consider the dynamic
biological processes of species and their interactions with their
environment: it is here that insights from long-term ecology can guide
conservation.
??????????? Palaeoecological
techniques like macrofossils, pollen analysis and sediment chemistry in
long-term ecology uses to resolve critical questions to resolve long-term
ecological changes and the processes behind such changes. Palaeoecological
record uses that preserved in lake and bog sediments as a long-term
ecological laboratory. The record delivers exclusive information about
ecological impact of environmental change on population, organisms,
communities, landscapes and ecosystems over time scales from 50 to 12000 years.
New developments mean that palaeoecological studies have high taxonomic
precision, fine temporal resolution (typically of ~5 years, and sometimes 1
or 2 years), appropriate numerical methods of analysis, and can benefit from
synergies of multi-proxy studies. Palaeoecological studies can help to answer
questions such as
? In the change of
ecosystem what are the major drivers at different time scales?
? In a specific
ecosystem how much natural variability is there?
? How have
landscapes changed over time?
? What is the native
status of particular species?
? Which ecological
processes are important for maintaining target ecosystems?
? How do human
activities affect the resilience of ecosystems to climate change?
? What time-lags can
be expected between climate change and ecosystem response?
? How will climate
change affect the distribution and impacts of climate-dependent disturbance
regimes such as fire?
??????????? Within
the application of long-term ecological data to conservation and management
there are many controversies, challenges, and compromises. Recently, a study
has emphasized a serious question in practical conservation: Do we know what
we want to conserve and how to conserve it? Two opposite ideas are
preservation of cultural landscapes and creation of partially 'wild' areas
with re-wilding. Long-term ecology has much to pay to conservation as the
complexity of processes and patterns in the past, when prudently decrypted,
can help to make? new ideas about management in the future. Biodiversity loss
is a local phenomenon and an in-depth understanding of individual locations
is needed to devise solutions.
??????????? This
special issue provides focused study on ecological forecasting and customized
decision support tools for a variety of topics. In this Special issue,
researchers spatially explicit modeling approaches to address complex
interactions, and relationships to solve the following issues:? Wildfire,
Climate Change Impacts, Species Population Modeling, Wildlife Connectivity,
Green Energy Development and Environmental Risk Avoidance conservation
problems.
