Impacts of global climate change on terrestrial ecosystems are imperfectly constrained by ecosystem models and direct observations. Pervasive ecosystem transformations occurred in response to warming and associated climatic changes during the last glacial-to-interglacial transition, which was comparable in magnitude to warming projected for the next century under high-emission scenarios. We reviewed 594 published paleoecological records to examine compositional and structural changes in terrestrial vegetation since the last glacial period and to project the magnitudes of ecosystem transformations under alternative future emission scenarios. Our results indicate that terrestrial ecosystems are highly sensitive to temperature change and suggest that, without major reductions in greenhouse gas emissions to the atmosphere, terrestrial ecosystems worldwide are at risk of major transformation, with accompanying disruption of ecosystem services and impacts on biodiversity.

The cerambycid beetles are important components in the terrestrial ecosystem as they play a dual role in both degrading dying trees and killing healthy plants. The factors including human activity, habitat contraction, climate changes and pesticide use have been shaping the adaptation of beetles to host plants and the environment. As suggested in research on the functions of beetles' olfactory proteins, odorant binding proteins (OBPs) have been found to be involved in insecticide resistance other than chemoreception.

Terrestrial ecosystems are a key component in the biogeochemical cycle of Hg. About 50% of atmospheric Hg is captured in the system because of the ability of vegetation to retain and subsequently transfer it to the soil surface through litterfall. In a stand dominated by Scots pine (Pinus sylvestris), the widest spatially distributed tree species in the northern hemisphere and the second worldwide, this two-year study evaluated monthly the litterfall Hg deposition fluxes (FHg) through all litterfall fractions involved (needles, twigs, bark, miscellaneous, and male inflorescences).

With the growing global emphasis on forest resource monitoring, evaluating the accuracy of retrieving key individual tree parameters-such as tree position, tree height, and diameter at breast height (DBH)-using Terrestrial Laser Scanning (TLS) has become an important research focus. TLS has been widely applied in forest surveys due to its significant advantages in data acquisition efficiency and measurement precision. However, studies on the accuracy of extracting forest parameters from single-station, single-scan TLS data remain limited, underscoring the need for systematic evaluation and validation.

Soil green algae play a crucial role in terrestrial ecosystems and enhance soil health. However, research on algal diversity and ecology in crop field soils, particularly in untilled perennial tree plantations, is scarce, and the factors influencing algal contributions to soil health and fertility management are not well understood. Therefore, an extensive study was conducted on the ecology and diversity of green algae in rubber crop plantations in South India, spanning diverse agroclimatic zones, soil orders, soil series, and seasons.

Though in the presence of enormous reducing power, life in serpentinizing systems is limited by oxidant and carbon availability. The forms of carbon that support the serpentinite-hosted microbiome, and their rates of biological assimilation, remain poorly understood.
