“…The plants at higher elevations have smaller leaf areas and thicker leaves [ 7 ]. Ke et al [ 35 ] documented that the leaf area of 39 herbaceous species decreased with increasing altitude in the northern Qinghai-Tibetan Plateau. In our study, the SLA first declined and subsequently increased with elevation.…”

Parthenium hysterophorus L. (Asteraceae) is a highly prevalent invasive species in subtropical regions across the world. It has recently been seen to shift from low (subtropical) to high (sub-temperate) elevations. Nevertheless, there is a dearth of research investigating the adaptive responses and the significance of leaf functional traits in promoting the expansion to high elevations. The current study investigated the variations and trade-offs among 14 leaf traits (structural, photosynthetic, and nutrient content) of P. hysterophorus across different elevations in the western Himalayas, India. Plots measuring 20 × 40 m were established at different elevations (700 m, 1100 m, 1400 m, and 1800 m) to collect leaf trait data for P. hysterophorus. Along the elevational gradient, significant variations were noticed in leaf morphological parameters, leaf nutrient content, and leaf photosynthetic parameters. Significant increases were observed in the specific leaf area, leaf thickness, and chlorophyll a, total chlorophyll and carotenoid content, as well as leaf nitrogen and phosphorus content with elevation. On the other hand, there were reductions in the amount of chlorophyll b, photosynthetic efficiency, leaf dry matter content, leaf mass per area, and leaf water content. The trait-trait relationships between leaf water content and dry weight and between leaf area and dry weight were stronger at higher elevations. The results show that leaf trait variability and trait-trait correlations are very important for sustaining plant fitness and growth rates in low-temperature, high-irradiance, resource-limited environments at relatively high elevations. To summarise, the findings suggest that P. hysterophorus can expand its range to higher elevations by broadening its functional niche through changes in leaf traits and resource utilisation strategies.

The genetic diversity of beneng taro can be known by analyzing morphological characters. This study aimed to determine the differences in morphological characters in beneng taro plants influenced by altitude using PCA and identify the level of uniformity of morphological characters in beneng taro plants using cluster analysis. This research is a qualitative study with a descriptive approach that is an exploratory survey. Sampling was carried out using a purposive sampling technique. In this study, samples were taken from three different altitudes, namely 343 masl (low), 615 masl (medium), and 761 masl (high) located in Serang Regency and Pandeglang Regency. Ten samples were taken in each location, so 30 taro beneng plants were collected. The research was conducted from January 2024 to March 2024. The variables observed in this study were morphological characters consisting of leaf blade color, leaf bone color, petiole color, plant height, leaf length, leaf width, and petiole length. The results showed that based on PCA, the characters that differed due to altitude were plant height, leaf blade color, leaf bone color, petiole color, petiole length, leaf length, and leaf width. In cluster analysis, 4 clusters were formed, indicating that the uniformity of the characters is relatively broad. Suggestions for further research on root and tuber morphology. Suggestions for farmers to continue cultivating beneng taro. The government should counsel the surrounding community about beneng taro, especially farmers who can preserve local commodities and support conservation efforts.

“…For desert plants and animals, these areas are crucial refuges. According to the stress-gradient hypothesis, as environmental stress, such as droughts and high temperatures, decreases, competition between plants and other organisms becomes more intense [7,8]. Facilitative interactions may be more prevalent on less stressful microsites.…”

The Hotan River, the sole river traversing the Taklimakan Desert in northwest China, sustains a critical desert riparian ecosystem dominated by Populus euphratica. This riparian habitat is integral to biodiversity maintenance. However, global climate change and anthropogenic disturbances have profoundly impacted the Taklimakan desert landscape, leading to fragmentation and reduced environmental heterogeneity. Consequently, there has been a notable decline in P. euphratica populations. This study aimed to assess the physiological resilience of P. euphratica under harsh conditions and analyze the vegetation distribution patterns along the desert riparian zone. Laboratory tests were employed to determine the physiological indexes including Relative Water Content (RWC), Chlorophyll (Chl), Soluble Sugar (SS), Free Proline (Pro), and Peroxidase Activity (POD) of P. euphratica, providing insights into its capacity to endure challenging environmental conditions. Quadrat surveys were conducted at varying distances from the riverbed to examine vegetation distribution patterns. Plant growth indexes were analyzed to unveil the resistance of the desert riparian forest to drought. The study identified 45 shrubs and herbs belonging to 17 families in the Hotan River understory, with P. euphratica exhibiting the highest abundance. In river flats, annual herbs dominated due to favorable water conditions, while shrub grasslands displayed a relatively complete community structure with trees, crowns, and grasses. As the distance increased from the river channel, more perennial herb and shrub species prevailed, leading to a decline in overall species richness as annual herbs diminished. Physiological assessments revealed that P. euphratica in a medium growth grade (VS3) exhibited the highest physiological indexes, indicating its adaptability to environmental changes. The findings underscore the significance of water conditions in the growth and development of vegetation in desert riparian forests, particularly highlighted by the physiological indexes of P. euphratica. This research contributes valuable insights that can inform the preservation and restoration of desert riparian forests, providing a scientific basis and technical guidance for conservation efforts.
