“…2a). Many past studies have shown that the height of trees decreases with increasing altitude because the low temperatures at high altitudes limit tree growth, photosynthesis, and the supply of soil nutrients (Lindborg et al 2021;Xu et al 2018). At the same time, at high altitudes, environmental stress is prominent, and plants can reduce the heat flow under the canopy by limiting their height, thereby preserving heat.…”

A positive diversity–productivity relationship has been demonstrated in planned experiments, but the evidence from field studies of natural forests is contradictory. We studied aboveground forest productivity in 28 subtropical montane forests on Mt. Fanjingshan and assessed the relationship between productivity and tree diversity, as well as climatic, edaphic, topography, and stand structural factors likely to influence productivity. The main determinants of aboveground net primary productivity (NPP) were climate factors and stand properties. They explained 35% of the variance in NPP. The percentage of the variance in NPP explained by stand properties, climate, soil properties, topography, and species richness were 55%, 30%, 7%, 5%, and 3%, respectively. Topography had no direct effect on production, but they had a significant indirect effect. Elevation had an indirect effect on production via tree height, and slope steepness had a significant indirect effect through climate factors. However, tree diversity had nonsignificant direct and indirect effects on productivity. We concluded that the productivity of highly diverse montane forests is primarily controlled by climate factors and stand structural properties rather than species diversity.

“…The increased growth of dwarf shrubs in general as well as for Vaccinium species is common in tundra or timberline sites (Shevtsova et al, 1997;Walker et al, 2006;Anadon-Rosell et al, 2017;Fazlioglu and Wan, 2021). Most warming studies, however, do not offer contrasts with lowland or southern populations of same plant species, but Lindborg et al (2021) found that northern-most populations of a common wetland species (Caltha palustris) showed the strongest growth responses to experimental warming along a latitudinal climate gradient. The contrast in warming-induced growth responses between high-and lowland populations (Table 5) may support theory that predicts increased growth with climate warming if other resources (i.e., moisture, nutrients etc) are not limiting.…”

Climate change impacts on species and ecosystem functioning may depend on climatic context and study systems. Climate warming and intensified herbivory are two stressors to plants that often appear in combination and are predicted to increase in cold environments. Effects of multiple drivers on plant performance are difficult to predict and warrant studies that use experimental manipulations along climatic gradients to produce more realistic knowledge. Our three study sites by the Sognefjord in Norway, that differed mainly in climatic conditions (ca. 5°C growing season difference), ranged from hemi-boreal lowland (100 masl, Low), via boreal mid-montane (500 masl) to alpine timberline (900 masl, High) bioclimates. At each site, in a randomized block design, we simulated growing-season warming using open-top chambers (OTCs) and experimentally induced herbivory resistance using the plant hormone methyl jasmonate (MeJA). We recorded growth, mortality, flower and fruit numbers, and insect herbivory on tagged ramets in permanent plots across three years (2016-2018) in three open woodland populations of two functionally important plant species with contrasting traits, Vaccinium myrtillus (bilberry) and V. vitis-idaea (lingonberry). Growth of both dwarf shrubs decreased with warming in the warm lowland populations (Low) but increased in the alpine populations (High). Shoot mortality increased most with warming at Low but was reduced at High. Reproduction, both flowering and fruiting, decreased with induced resistance treatment, but the effect was larger when warmed for bilberry and increased with elevation for both species. Leaf herbivory in bilberry increased with warming at Low but decreased at High. The combined warming and resistance treatment had only synergistic negative interaction effects on fruit numbers in bilberry. The clear context- and species-dependent effects of climate warming and increased resistance in this study may predict a potential decline in performance, as well as abundance and distribution, of these functionally important Vaccinium species at our lowest site. Bilberry reproduction appeared to be particularly susceptible to both climate warming and induced resistance in the manipulated populations. Such combined negative effects on plant performance are likely to have considerable knock-on effects via altered species’ interactions and ecosystem functioning.

“…For instance, global warming, which indicates the rising in temperature, affects both plants 'functions in their traits and ecosystems. Since wetlands are essential ecosystems and conditions within those highly depend on vegetation, the change in plants 'function can affect the ecological condition of wetlands to a great extent [8]. In Lindborg's study, a group of researchers conducted a temperature manipulation experiment along the latitudinal gradient.…”

Wetlands are an important part of the biosphere. Wetlands not only impact the natural environment but also play vital roles in human life. This paper starts with the classification, distribution, and main functions of wetlands, then analyzes the relationship between wetlands and the biosphere from several aspects, including the factors that affect wetlands, the biomass of wetlands, the importance of wetlands for carbon storage, and the threats that wetlands may face. Based on previous research, wetlands can be impacted by environmental factors, such as water supply and temperature, and biological factors, including aboveground biomass and below-ground biomass. When interacting with these factors, wetlands can play crucial roles in the biosphere, such as facilitating the circulation of energy and materials and the storage of carbon. However, wetlands are facing threats. After analyzing the current state of wetlands, possible solutions are considered. Both research and society can make efforts to improve wetlands ecosystems. This report is significant for understanding the current situation and the direction of future development of wetlands. It is crucial to study the environmental factors affecting wetlands, considering the protection, improvement, and future development of wetland ecosystems depend on their surroundings to a great extent. Interactions between wetlands and the environment directly or indirectly determine the state of wetlands.
