“…Our findings agree with previous studies done by Díaz Villa et al [32], and Laurindo et al [14], that reported high SOC content, and high abundance of C. etunicatum, F. geosporum, F. mosseae, and R. aggregatum, in invaded environments by Pinus taeda. We must consider that the IAPS uses different pathways to build new habitat around its rhizosphere through changes in the chemical, physical, and biological compartments into the soil ecosystem [13].…”

Invasive alien plant species (IAPS) have the ability to change the biochemical properties and the arbuscular mycorrhizal fungal (AMF) community structure in their rhizosphere. Organic acids, microbial activity, and AMF play a key role in the invader's spread and also has interactions with the soil chemical factors. Our aim here was to assess the rhizosphere's biochemical factors, AMF community composition, and soil chemical properties associated with Cryptostegia madagascariensis (IAPS) and Mimosa tenuiflora (endemic plant species) from the Brazilian Seasonal Dry Forest. The highest values of total glomalin (5.87 mg g−1 soil), root colonization (54.5%), oxalic and malic acids (84.21 and 3.01 μmol g−1, respectively), microbial biomass C (mg kg−1), Na+ (0.080 cmolc kg−1), Ca2+ (7.04 cmolc kg−1), and soil organic carbon (4.59 g kg−1) were found in the rhizosphere of C. madagascariensis. We found dissimilarities on AMF community structure considering the studied plant species: (i) Racocetra coralloidea, Dentiscutata heterogama, Dentiscutata cerradensis, Gigaspora decipiens, and AMF's richness were highly correlated with the rhizosphere of M. tenuiflora; and (ii). The rhizosphere of C. madagascariensis was highly correlated with the abundance of Claroideoglomus etunicatum, Rhizoglomus aggregatum, Funneliformis mosseae, and Funneliformis geosporum. The results of our study highlight the importance of considering C. madagascariensis as potential hosts for AMF species from Glomerales, and a potential plant species that increase the bioavailability of exchangeable Na and Ca at semi‐arid conditions.

“…Selain itu penelitian dari Villa, et al (2022) yang berfokus pada perubahan kapasitas penyerapan karbon (C) melalui modifikasi struktur vegetasi dan fungsi ekosistem akibat adanya perubahan penggunaan lahan dan kegiatan yang dilakukan manusia di atas permukaan tanah. Tujuan penelitian ini adalah untuk menganalisis produktivitas primer bersih dari aktivitas yang berada di permukaan tanah (aNPP) terhadap umpan balik karbon tanah dan unsur hara di subtropis yang Lembap.…”

“…Tujuan penelitian ini adalah untuk menganalisis produktivitas primer bersih dari aktivitas yang berada di permukaan tanah (aNPP) terhadap umpan balik karbon tanah dan unsur hara di subtropis yang Lembap. Hasil penelitian ini menunjukkan bahwa aktivitas manusia tidak secara langsung mengakibatkan adanya degradasi proses ekosistem di atas permukaan tanah tetapi aktivitas manusia memiliki dampak pada proses di bawah tanah dan stok tanaman pinus yang juga berpengaruh pada pengelolaan hutan (Villa et al, 2022). Persamaannya adalah sama-sama membahas peran manusia dalam mengolah alam (lingkungan) yang dalam hal ini adalah pengelolaan hutan.…”

Penelitian ini dilatarbelakangi dengan adanya Kalimantan sebagai wilayah Hutan Tropis Lembab memiliki pengaruh pada pembangunan Ibu Kota Nusantara sebagai barometer khususnya dalam bidang pendidikan. Oleh karena itu, penting untuk mempersiapkan Sumber Daya Manusia yang mampu berdaya saing khususnya tahun 2045. Maka dari itu, tujuan penelitian ini meneliti bagaimana Perspektif Dosen di Magister Pascasarjana Universitas Islam Negeri Sultan Aji Muhammad Idris Samarinda terkait Sumber Daya Manusia berbasis Hutan Tropis Lembab dan Lingkungannya. Metode penelitian ini menggunakan penelitian lapangan dengan pendekatan kualitatif deksriptif. Sumber data dari hasil observasi, dokumentasi, dan wawancara. Kemudian dilakukan triangulasi dan dianalisis dengan teknik kondensasi, penyajian data, dan kesimpulan. Berdasarkan perencanaan, pengorganisasian, pelaksanaan, dan pengawasan, hasil penelitian menunjukkan bahwa belum ada realisasi pelaksanaan secara tersistem dan terstruktur melalui Mata Kuliah Hutan Topis Lembab dan Lingkungannya dan minimnya literatur kampus dan juga penelitian mengenai hal tersebut. Namun, dalam tata kelola kampus telah mendukung Ibu Kota Negara melalui implementasi makna slogan "Kampus Hijau". Dosen berharap akan ada keseimbangan dengan cara Universitas Islam mempertimbangkan Ayat-ayat Kauniyah untuk bersanding dengan Hutan Tropis Lembab dan Lingkungan ke depannya.

“…The allochthonous carbon in the form of leaves, fruits, flowers, and wood has been recognised as the main energy source to forested headwaters as their dense riparian vegetation limits light penetration and consequently instream autochthonous primary production [4,5]. Agricultural and forestry activities in basins can significantly alter the sources of carbon entering stream ecosystems and, at the same time, alter light entrance to streams, affecting carbon production by primary producers [6,7]. Moreover, changes in the native tree riparian vegetation affect the quantity and quality of organic matter inputs reaching streams that may have consequences on the functioning of these ecosystems [8,9].…”

Despite the reported allelopathic nature of the Eucalyptus genus, eucalypt leachates have unknown effects on the trophic base of stream green food webs. Eucalypt plantations have increased worldwide, including riparian ecosystems. We aimed to test whether short-term eucalypt leachates might alter water chemistry, periphytic algal biomass and diatoms, and herbivorous invertebrates’ (i.e., scrapers). We studied two oligotrophic and well-preserved headwaters from NW Spain. The experiment followed a before-after control-impact paired (BACIp) design, with weekly sampling before and after eucalypt leaves addition to streams. In the stream with lower discharge, the eucalypt treatments seemed to affect increases in biomass accrual (Chl-a) and diatom assemblages, disfavouring sensitive species (e.g., Eunotia minor and Achnanthidium pyrenaicum). Therefore, the ecological status was reduced from high to good. In the stream with higher discharge, invertebrate assemblages changed with scrapers having their abundances modified in comparison with the control (e.g., Habrophlebia sp. and Elmidae). Results suggest that eucalypt leaves leachates exert toxic effects on periphyton and on diatom and invertebrate assemblages, and this effect might be mediated by discharge. Alterations at the base of stream food webs may compromise their good ecological status. Further studies are necessary to identify whether this toxicity is due to allelopathic processes.
