Historical Factors

Ectomycorrhizal fungi (EcMF) are involved in soil nutrient cycling in forest ecosystems. These fungi can promote the uptake of nutrients (e.g., nitrogen (N) and phosphorus (P)) and water by host plants, as well as facilitate host plant growth and resistance to stresses and diseases, thereby maintaining the aboveground primary productivity of forest ecosystems. Moreover, EcMF can acquire the carbon (C) sources needed for their growth from the host plants. The nutrient regulation mechanisms of EcMF mainly include the decay of soil organic matter via enzymatic degradation, nonenzymatic mechanism (Fenton chemistry), and priming effects, which in turn promote C and N cycling. At the same time, EcMF can secrete organic acids and phosphatases to improve the availability of soil P, or increase mycelium inputs to facilitate plant acquisition of P. The spatiotemporal distribution of EcMF is influenced by a combination of historical factors and contemporary environmental factors. The community of EcMF is associated with various factors, such as climate change, soil conditions, and host distribution. Under global climate change, investigating the relationships between the nutrient cycling functions of EcMF communities and their distribution patterns under various spatiotemporal scales is conducive to more accurate assessments of the ecological effects of EcMF on the sustainable development of forest.

<p>Deforestation occurs around the world; though tropical rainforests are particularly targeted, it is considered to be one of the contributing factors to global climate change. While Nigeria is probably best known today for its oil deposits, according to the World Resources Institute, Nigeria is home to 4,715 different types of plant species, and over 550 species of breeding birds and mammals, making it one of the most ecologically vibrant places of the planet. It is also one of the most populous country with appalling deforestation record. This situation is hence making our ecosystems, biodiversity, agriculture and other natural endowments highly unsecured. The Forest provides excellent resources for bees and beekeeping, and bees are a vital part of forest ecosystems. Bees are essential for sustaining our environment because they</p><p>Pollinate flowering plants and conserves biological biodiversity along with their products (honey, propolis, bee wax, royal jelly and bee venom) which are beneficial to man. Conservation of the forest is therefore imperative for sustainable beekeeping. The study reviews the different causes of climate change and how they affect different natural forest activities which are weather-dependent. Also how climate change and other causes (both natural and man-made) lead to deforestation, which in turn distort sustainable honey production in Nigeria. Different sustainable measures hoped to alleviate the effects of climate change and deforestation where also discussed. </p>

Abstract Increase in atmospheric CO2 concentration ([CO2]) and associated soil warming along with global climate change are expected to have large impacts on grain mineral nutrition in wheat. The effects of CO2 elevation (700 μmol l−1) and soil warming (+2.4 °C) on K, Ca and Mg concentrations in the xylem sap and their partitioning in different organs of wheat plant during grain filling were investigated. Results showed that the combination of elevated [CO2] and soil warming improved wheat grain yield, but decreased plant K, Ca and Mg accumulation and their concentrations in the leaves, stems, roots and grains. The reduced grain mineral concentration was attributed to the lowered mineral uptake as exemplified by both the decreased stomatal conductance and mineral concentration in the xylem sap. These findings suggest that future higher atmospheric [CO2] and warmer soil conditions may decrease the dietary availability of minerals from wheat crops. Breeding wheat cultivars possessing higher ability of mineral uptake at reduced xylem flux in exposure to climate change should be a target.

Abstract Tropical regions are biodiversity hotspots and are well suited to explore the potential influence of global climate change on forest ecosystems. Bryophytes have essential ecological functions in tropical forest ecosystems. Knowledge of the potential impact of global warming and possible changes in water availability patterns on terrestrial bryophytes is limited. We transplanted eight moss species from two elevations (900 and 500 m) to warmer and drier elevations (500 and 100 m) during a half-year observation period on Tai Mo Shan, southern China. The simulated climate change resulted in a marked decrease in growth and a negative effect on the health of the transplanted species. Few moss species survived six months after transplanting to the warmer and drier lowlands, and their health status deteriorated severely. Three moss species, Sematophyllum subhumile, Pseudotaxiphyllum pohliaecarpum, and Brachythecium buchananii, were highly susceptible to changes in temperature and moisture and might be used as suitable bioindicators. As the tropics are expected to become hotter and drier, terrestrial mosses might be negatively affected or even be at risk of extinction. The cascading negative effects on the forest ecosystem might be induced by the dying back or even disappearance of terrestrial moss species. Thus, conservation of bryophyte communities is important to sustain and improve the stability and resilience of tropical forest ecosystems to climate change.

The Crimean Peninsula

Studying the response of forest ecosystems to climate change is one of the urgent tasks of modern ecology. Regional manifestations of global climate change lead to special reactions of forest ecosystems. The main source of energy for all processes in ecosystems is solar radiation. It starts all the processes of transformation of matter, energy and information in the ecosystem. A change in its income leads to a restructuring of the ecosystem functioning system. For the Crimean Peninsula today the response of forest ecosystems to climate change remains poorly studied. This determines the relevance and purpose of this work. On the base of the landscape-typological map of the Crimean Peninsula, open reanalysis databases, and GIS modeling, the elements of the radiation balance of the oak forest ecosystems of the Crimean peninsula are estimated under the conditions of modern climate changes. The basic laws of the radiation balance formation of oak forest ecosystems and the features of its interannual dynamics are shown.

The Impact

The paper deals with the impact of climate change on the forest resources of the Republic of Bashkortostan. The basis of forest cover is formed by stands with a predominance of pine, spruce, birch, linden, alder, aspen, and oak. Climate changes directly or indirectly affect the state of forest ecosystems and, as a result, the development of the entire forestry complex of the Republic. The climate affects the productivity, species composition of forests, as well as their resistance to destructive natural and anthropogenic factors. One of the most pressing issues today is the assessment of the significance of the ongoing climate changes for forest ecosystems, both in the field of fundamental research and in the planning of socio-economic development of regions. Indicator plants confirm ecological displacement of the distribution areas of plant species due to changes in temperature and hydrological regimes, as well as anthropogenic factors. Proceeding from the fact that the type of forest is derived from climate, terrain, groundwater level, soil conditions, there is a problem of forecasting the climatically determined dynamics of the forest based on the current relief of the area and soils in the Republic of Bashkortostan

Indonesia is one of the mega-biodiversity countries that have a great responsibility in maintaining the balance of the global climate and forest ecosystems. Drought causes shifting of ecosystems causing disturbances on animal life leading to death of species. Alongside fires in the savanna, drought is a recurrent problem in the park, which occurs every year. This study aims to detect the abundance of water by using satellite imagery in Baluran National Park (BNP). The research analyzed using Landsat satellite imagery ETM7 + in 1999 and 2010 and three (3) main factors that have great potential abundance of water, are: (1) plant density (GI = Greenness Index), (2) soil moisture (WI = Wetness Index), and (3) soil conditions (SBI = Soil Brightness Index). Three factors are summed and divided by three to get 5 levels of water abundance: 1) Very abundant, 2) Abundant, 3) Medium, 4) Few, and 5) Very little. The results showed that the abundance of water decreased between 1999 and 2010 for moderate conditions from 85% to 38%, if the abundance of low water (slightly) increased from 15% to 60%. The level of accuracy of the abundance of water in the field of more than 80% is exactly 91%. The extreme drought conditions will be very dangerous for the survival of flora and fauna in Baluran National Park that are in desperate need of water and potentially in danger of a fire. Construction of water reservoirs and water supply continuously using a water tank in the dry season is very necessary in the Baluran National Park.
