“…In this regard, geographical gradients represent a broad range of environments, especially along latitudes from north to south. Over altitude and latitudinal–longitudinal gradients, multiple environmental factors, including total solar and UV-B radiation, temperature, precipitation, nitrogen availability, aridity indices, soil fertility and acidity, exposure, and even land-use history, varied substantially [ 26 ]. Consequently, geographical gradients can be treated as factors generating environmental effects and are expected to influence specialized metabolism in plants.…”

The traditional widely used raw material of Achillea millefolium is currently mainly derived from wild populations, leading to diversification and uncertainty in its quality. The aim of the study was to determine the accumulation differences of phenolic compounds between geographically distant populations of Achillea millefolium from northern and southern gradients. Plant material was collected from Gaziantep and Nevşehir provinces in Turkey and from wild populations in Lithuania. A complex of nine hydroxycinnamic acids and eleven flavonoids was identified and quantified in the methanolic extracts of inflorescences, leaves, and stems using the HPLC-PDA method. Caffeoylquinic acids predominated in leaves, while inflorescences tended to prevail in flavonoids. The PCA score plot model represented the quantitative distribution pattern of phenolic compounds along a geographical gradient of populations. The content of phenolic compounds in plant materials from northern latitudes was more than twice that of plants from southern latitudes. A significant correlation of individual phenolic compounds with latitude/longitude corresponded to their differences between two countries. Differences in accumulation of caffeoylquinic acids and flavonoids revealed several intraspecific groups within A. millefolium. Our findings suggest that spatial geographical data on the distribution of phenolic compounds in A. millefolium populations could be used as a tool to find potential collection sites for high-quality raw materials.

“…Forest dynamics describe how forests grow, change, and react to environmental pressures, with key components of tree mortality, growth, and recruitment [30,31]. Anthropogenic influences, especially agricultural activities, are the primary cause of tropical dry forest alteration.…”

Tropical Dry Forest Diversity, Climatic Response, and Resilience in a Changing Climate

Central and South America tropical dry forest (TDF) is a water-limited biome with a high number of endemic species and numerous ecosystem services which has experienced a boom in research in the last decade. Although the number of case studies across these seasonal, water-limited, tropical forests has increased, there has not been a comprehensive review to assess the physiological variability of this biome across the continent and assess how these forests respond to climatic variables. Additionally, understanding forest change and resilience under climatic variability, currently and in the future, is essential for assessing the future extent and health of forests in the future. Therefore, the objective of this paper is to provide a literature review on the variability of TDF diversity and structure across a latitudinal gradient and to assess how these components respond to differences in climatic variables across this geographic area. We first assess the current state of understanding of the structure, biomass, phenological cycles, and successional stages across the latitudinal gradient. We subsequently review the response of these five areas to differences in precipitation, temperature, and extreme weather events, such as droughts and hurricanes. We find that there is a range of adaptability to precipitation, with many areas exhibiting drought tolerance except under the most extreme circumstances, while being susceptible to damage from increased extreme precipitation events. Finally, we use this climatic response to provide a commentary on the projected resilience of TDFs under climatic changes, finding a likelihood of resilience under drying scenarios, although model projections do not agree on the magnitude or direction of precipitation change. This review of quantitative studies will provide more concrete details on the current diversity that encompasses the TDF, the natural climatic ranges under which this ecosystem can survive and thrive, and can help inform future forest management practices under climate change scenarios.

Sustaining subsistence culture in Mamar agroforestry management in West Timor, is it possible?

et al. 2020

View full text Add to dashboard Cite

A subsistence culture which has moral values related to the protection of ancestral territories and the environment, must be maintained in the management of Mamar agroforestry. On the other hand, subsistence culture is often seen as a counter-modernization culture because it is not commercially oriented. This paper aims to provide an overview of the subsistence culture and its relationship to the preservation of Mamar agroforestry and the potential stresses it faces, as well as quantify the opportunities for sustaining a subsistence culture in today’s West Timorese society. The method used is literature study using Google Scholar and other relevant literature. As it is known, the demands of life necessities and lifestyles, global climate change, and government policies are the pressing factors for land conversion, including in Mamar. On the other hand, a culture of subsistence tends to maintain moral values in cultivating land that preserves nature, thereby reducing pressure for Mamar land conversion. The conclusion obtained is that a subsistence culture needs to be maintained and become a locomotive for maintaining the sustainability of development as a whole, by reducing the causes of vulnerability in society. Economic and social interests can be integrated due to compliance with strong social structures.
