Trinidad is a type locality for two widely applied names with poorly defined species concepts: <em>Arthrostylidium pubescens</em> and <em>A. excelsum</em>, and two potentially endemic species: <em>Chusquea cylindrica</em> and <em>Rhipidocladum prestoei</em>. Few resources exist for the islands to adequately identify all the woody bamboo species that putatively grow there. The serialized vascular flora of Trinidad and Tobago (1928–1992), for instance, lacks a treatment for Poaceae. Moreover, the most speciose native genus, <em>Arthrostylidium</em>, is only partially revised, with the emphasis on the South American species and not those of the West Indies. Our objective is to critically review the woody bamboos of Trinidad and Tobago, clarify which species are or have been known from the islands, and provide an identification key, species accounts and distribution maps for the revised list of taxa. We conducted fieldwork campaigns in 2021–2023, and reviewed herbarium specimens and human observation records of woody bamboos from the islands. Newly collected specimens were vouchered and all woody bamboo records were georeferenced and plotted using QGIS. We confirmed two species of native woody bamboo and four species of introduced woody bamboo were extant on Trinidad. An additional three Western Hemisphere species have historic records of occurrence on the islands. Native species diversity correlated well with previously identified floristic hotspots. One introduced species, <em>Bambusa vulgaris</em>, is common on both islands. To the best of our knowledge, there are currently no native woody bamboo species present on Tobago, however, <em>A. pubescens</em> appears to have been growing along the Main Ridge in the past. The historic presence of some species not currently found may be the result of dynamic and/or stochastic colonization events among the islands and mainland South America.</p></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277313912400003X/pdfft?md5=dbac8d2e45ec2e71257e13b4f1a21537&pid=1-s2.0-S277313912400003X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139487594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bamboo offers an affordable, renewable, CO₂-absorbent material with high tensile strength. This research supported low-income communities by exploring the application of bamboo-reinforced concrete (PB) foundation plates. Technical feasibility, such as load capacity, crack pattern, and failure, were examined and compared with steel-reinforced concrete (PS) plates. Four foundation specimens with dimensions of 70 × 70 × 15 cm³ consisting of three PB foundation plates and one PS foundation were analyzed. The bamboo reinforcement had dimensions of 15 mm × 15 mm, and the steel reinforcement had a diameter of 10 mm. Different spacing variations were tested, including bamboo reinforcement spacings of 100 mm, 125 mm, and 150 mm, with a steel reinforcement spacing of 130 mm. During testing, a concentrated load was applied at the four corners of each foundation. The results showed that the PB foundation plate with a reinforcement spacing of 100 mm exhibited a 3.16% higher load capacity compared to PS foundation plate with a 10 mm reinforcement spaced at 130 mm. The stress zones, crack patterns, and failure modes of the PB foundation plates exhibited similarities to the PS foundation serving as the control. Based on these findings, PB foundation plates are a feasible option for a simple rural house foundation.</p></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773139124000016/pdfft?md5=eb361ea47f9290336dca2077a40ad864&pid=1-s2.0-S2773139124000016-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139494208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As bamboo ecosystems in Cameroon are poorly known, this study sought to evaluate the distribution of bamboo, develop allometric equations for it and estimate carbon stocks associated with bamboo in the Western Highlands of Cameroon. Landsat 8 OLI imagery was used to increase data on the distribution and carbon stocks of <em>Phyllostachys aurea</em> Carrière ex Rivière &amp; C. Rivière in the study area. <em>P. aurea</em> is reportedly the most exploited species for ecological, socioeconomic and cultural activities in the region, posing a challenge for the sustainability of the species. Twelve circular plots were established in <em>P. aurea</em> stands in the Western Highlands. Five per cent of the bamboo stems were harvested. Every stem was sorted into leaves, branches, and culms. These were weighed, and sub-samples taken to the laboratory. Sub-samples were oven-dried for biomass estimation. Regression analysis was used to develop the allometric equations. The best equation was used to estimate the carbon stocks. The Western Highlands region of Cameroon is estimated to have 241,296 ha of bamboos. The dominant bamboo species identified in the study area include <em>Oldeania alpina</em> (K.Schum.) Stapleton (syn. <em>Yushania alpina</em> K.Schum.), <em>Bambusa vulgaris</em> Schrad. ex J.C.Wendl. and <em>P. aurea</em>. Focusing on <em>P. aurea</em> the best fit equation with a bias of − 6.98%, Adj.R² = 0.711, AIC = 17 and RSE = 0.262, was selected. The mean density of <em>P. aurea</em> was 38,017 ± 4510 culms.ha⁻¹. The mean culm aboveground biomass was 3.15 ± 0.94 kg. The AGB of <em>P. aurea</em> was estimated at 119.05 ± 3.63 t.ha⁻¹, mean AGC was 55.95 ± 5.81 t C.ha⁻¹ and mean aboveground carbon dioxide equivalence (AGCO_2eq) was 205.35 ± 58.01.22 t CO₂.ha⁻¹. <em>P. aurea</em> constitutes a significant carbon sink in the Western Highlands of Cameroon.
