Abstract
adapt to variety of environments. Dynamics of a nematode community are highly associated with the condition, which can serve as an indicator for monitoring the impact of human activity on the soil ecosystem. However, a systematic study on nematode fauna is lacking in many regions across Taiwan. In this study, we provide morphological and molecular identification for the soil nematodes collected during the cultivation process of the first crop rice in , Taiwan. Within the three-year survey, 26 morphospecies of 18 genera were identified in the soil from the rice paddy fields. Each morphospeices was initially identified based on morphology, and 11 were further examined using 18S rDNA sequences. Among these, nine predominant morphospeices represented over 90% of the abundance, while juveniles of the plant pathogenetic nematode, Meloidogyne, were the most abundant one. Bacterivore was the most diverse and abundant functional group in the nematode community. Eight morphospecies were supported by the molecular identification at the genus level, while three require further consideration due to inconsistencies between morphological and molecular analyses.

Abstract
To study how species composition and physiognomical structure of mixed cloud forest in changes along main soil, topographical and microclimatic variables on a small scale, we established a 1-ha Forest Dynamics Plot in northern Taiwan (24°43ʹ N, 121°26ʹ E, elevation 1758–1782 m a.s.l.). Plot is affected by prevailing NE wind direction related to winter monsoon, and by seasonal fog frequency with highest fog density in autumn and winter. We finished the first census of all woody species in August 2020, and collected environmental factors related to soil and topographical properties, measured microclimate and soil moisture within the plot. In total, we recorded 5220 individuals with diameter at breast height ≥ 1 cm. These belong to 65 species, 42 genera and 29 families, with a basal area of 69.1 m2 ha-1, and are dominated by Chamaecyparis obtusa var. formosana, Rhododendron formosanum and Quercus sessilifolia. Modified classified vegetation into three types (ridge, east-facing slope and valley). Unconstrained ordination showed that the main gradients behind species composition changes are related to windwardness and convexity. Both east-facing slope type and valley type have relatively lower temperatures than ridge type, especially during summer. Convexity is related to soil moisture gradient (from dryer convex to wet concave sites). From soil properties, pH is negatively and phosphorus is positively related to topographical convexity. Collected data will serve as a baseline for future resurveys and monitoring changes within this montane cloud forest.

Abstract
A new species, ( : ), is described from Taiwan. It is found exclusively on the scree slopes of Mt. Zhongyangjian in the Central Range of . This species is distinctive in having shallowly trilobed, trident-like leaves with densely white arachnoid-tomentose abaxial surfaces. Its leaf morphology resembles A. tridentata, A. integrifolia and A. stolonifera to some extent, but can be readily distinguished by its smaller leaf size, pattern of leaf lobes and relatively uniform leaf shape. Both capitulum morphology and molecular phylogenetic analysis indicate that A. tyuosenicola belongs to A. subg. Artemisia. A detailed description and a distribution map of A. tyuosenicola are also provided herein.

Taiwania 2024 vol.69 no.3: pp.321-335
Abstract
Communal forests are recognized to be of critical importance for the attainment of sustainable development goals (SDGs) but these are often understudied. Such is the case in Cordillera Central Range with its unique biodiversity and urban biodiversity sites requiring protection like the Alapang Communal Forest in Benguet, Northern Philippines. This study documented the floral diversity, carbon stock and the community perspectives as baseline for conservation. A total of 187 plant species belonging to 145 genera and 70 families were recorded with Pinus kesiya as the most dominant species. The forest exhibited high species richness, evenness, and diversity including indigenous, endemic species and some conservation important species. The total forest carbon was estimated at 6,931.44 t with an average of 192.54 t/ha. An interesting trade off was documented in the study with the pine dominated ridge stations having lower diversity but higher carbon stock while broad-leaf dominated depressed stations have higher diversity but lower carbon stock. Community surveys revealed the willingness to protect the forest due to its crucial role as a water source, highlighting its value and the importance of preservation. These findings offer empirical evidences on the role of communal forest on biodiversity conservation, carbon stock as well as forest goods and services. Locally, these findings offer insights for conservation and sustainable management of the Alapang Communal Forest and other local urban forests.

Abstract
Several individuals of an unidentified taxon were discovered in City, Prefecture, . Detailed morphological analysis suggests that this taxon is a natural hybrid between Goodyera schlechtendaliana and Goodyera henryi, based on characteristics such as leaf margins, texture, venation patterns, rachis length, hair morphology on the o***y, and the shapes of the lip apex and rostellum. Supporting this, molecular data from genome-wide markers using next-generation sequencing (MIG-seq data) indicate that G. ×kazumae is a hybrid between G. schlechtendaliana and G. henryi. Neighbor-Net phylogenetic analysis shows G. ×kazumae occupies an intermediate position between the putative parent species. STRUCTURE analysis further confirms that G. ×kazumae comprises genetic components from both species. Therefore, we conclude that this taxon is a natural hybrid based on comprehensive morphological and molecular evidence.

Although India belongs to one of the 17 megadiverse countries of the world, little is known about its ectomycorrhizal fungi in general, and in particular. In the present communication, with the combined approach of multigene molecular phylogeny and morphological study, the diversity within sensu lato has been revealed and has supported the recognition of at least eight species in this complex. Moreover, a new species in this complex namely, Sutorius apleurocystidiatus, is also proposed and described from India with morphological details and molecular phylogeny.

Abstract
Collecting basic biological information of a species is crucial for developing effective conservation strategies and ensuring its sustainable management. is considered a vital, possibly the primary, nursery ground for the endangered sicklefin lemon shark ( ) in the South China Sea. In this study, we employed acoustic telemetry to investigate the habitat utilization and preferences of N. acutidens at different life stages in Dongsha Atoll. A total of 44 sharks, including 16 juveniles, 14 small sharks, 11 sub-adults, and three adults, were tagged and tracked for 1–848 days. Results of this preliminary assessment revealed that: (1) juvenile and small sharks commonly utilize the shallow seagrass flats around Dongsha Island, with juveniles spending a significant amount of time in the embedded lagoon; (2) sharks of all sizes utilize the lagoon mouth area, especially small and sub-adult sharks; (3) adult sharks exhibit a broader activity range within the atoll and are unlikely to enter the embedded lagoon. We hypothesize that the embedded shallow lagoon of Dongsha Island serves as a shelter area for newborns and juveniles, while the lagoon mouth may function as an important hunting ground for small and sub-adult sharks. Adult sharks may have the broadest home range around the atoll and close to Dongsha Island during the breeding season. This study underscores the importance of considering habitat shifts and changes in home range size throughout the ontogeny of N. acutidens when planning effective spatial management strategies.

We conducted a comprehensive analysis of an eBird dataset, a global citizen science initiative, to systematically assess the winter waterbird biodiversity hotspots at a 1-km grid scale throughout Taiwan. This assessment considered five criteria: species richness, abundance, and national, regional, and local importance values. We identified 994 grids as hotspots, with 132, 154, 137, 205, and 366 grids meeting all five, four, three, two, and one of the five criteria, respectively. The hotspots are located in the coastline region, and only 32.60% are located within the protected areas, implying that winter waterbird hotspots extend beyond the protected areas and significantly overlap with anthropogenic activity area. Our findings highlight the limitations of traditional protected areas in effectively conserving winter waterbird hotspots, thereby demanding the adoption of more proactive and strategic management approaches to promote sustainable coexistence between humans and nature. By analyzing the crowdsourced scientific data, this study fills spatial gaps and provides a systematic method for rapidly assessing biodiversity distribution, generating up-to-date information for biodiversity management that aligns with the current status.

Abstract
Mining of manganese leads to significant heavy metal contamination, affecting the adjacent ecosystems. Therefore, it is crucial to monitor heavy metal levels in mining areas. This study examined heavy metal concentrations (Cr, Mn, Cu, Zn, Sr, Mo, Cd, and Pb) in vegetation and soil within the wetland area of the slag discharge field in County, Province, . The assessment utilized the single-factor pollution index method (P_i), Nemerow comprehensive pollution index method (P_n), and correlation analysis. Two local plant species, Philonotis and Spirogyra, were used as sample materials. The findings revealed varying degrees of heavy metal contamination across all sites, with intensity increasing closer to the slag discharge area. Notably, Philonotis displayed a higher heavy metal accumulation capacity than Spirogyra. Statistical analysis revealed a significant positive correlation (P < 0.05) between Philonotis and soil heavy metals (Mn, Zn, and Cd) and between Spirogyra and specific soil heavy metals (Mn and Sr). Linear fit analysis indicated a strong association between Philonotis and soil manganese, suggesting that Philonotis is an effective bioindicator for monitoring environmental heavy metal pollution in slag discharge field wetlands. The manganese content in Philonotis exceeded 10,000 mg/kg, indicating potential as a hyperaccumulator, warranting further investigation. This research supports the use of Philonotis as a biological tool for monitoring heavy metal pollution in wetland ecosystems affected by manganese mining.
