(Zingiberaceae) is represented by 141 species distributed mainly in tropical forests of Asia. From Maharashtra 7 species have been reported (Sharma et al. 1996, Almeida 2009, Chandore et al. 2012). These plants are characterized by inflorescence arising directly from the rhizome with peduncle very short or absent. Earlier floristic studies in Satpuda hills of Khandesh region have not recorded any wild ginger species belonging to the genus Zingiber (Patil 2003, Kshirsagar 2008, Khan 2019). During our botanical survey of Satpuda hills, we came across a colony of herbaceous plants with distichous leaves with basal sheaths overlapping to form pseudostem, in Aamba Pani forest of Satpuda hills of Jalgaon district, on hill slopes dominated by Bamboo Dendrocalamus strictus (Roxb.) Nees and Karvi Strobilanthes callosa Nees vegetation, sharing habitat with Cheilocostus speciosus (J. Koenig) C. Specht, and Habenaria plantaginea Lindl. Detailed morphological examination of the specimen observed with the help of literature confirmed it as Zingiber roseum (Roxb.) Roscoe. Close examination with the help of pertinent literature revealed that this species is not recorded earlier from Satpuda hill ranges of Jalgaon district, and Khandesh region of Maharashtra. It is the new distributional record of this species from Satpuda ranges, Maharashtra state. The occurrence of this rare wild ginger species underlines its range extension from western ghats to Satpuda hills, signifying floral wealth of Satpuda hill ranges.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77812745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The seasonal variation in the elemental composition of the three red algae species showed that most of the minerals were found to accumulate during the summer season followed by premonsoon season. This could perhaps be due to the ambient concentration of these minerals were high during these seasons; thereby facilitating their uptake by seaweeds. The accumulation factor of certain irons by the algae were also discussed in this paper.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74747258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed yield models for the young Tectona grandis stands in Nnamdi Azikiwe University Awka, Southeastern Nigeria. These models were necessary to the guide forest managers in timber valuation as well as monitoring growth of the stand. Data for this study was collected through complete enumeration method, tree height and stem diameters of the 295 Teak stands were measured. Non-destructive method (Newton’s formula) was used in computing individual tree volumes. The tree growth variables data were subjected to descriptive statistics and used for fitting five nonlinear regression functions. The mean stem height, diameter at breast height and volume were 10.6 m, 8.9 cm, 0.032 m3, respectively. Out of the five yield equations fitted; the generalized combined variable model had the best predictive ability; with the lowest root mean square error (0.0084 m3) and Akaike information criterion (-2809). Therefore, the generalized combined variable model was recommended for yield estimation of Tectona grandis.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78751309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was undertaken to assess the firewood consumption pattern by households living near community forests of East Khasi Hills District, Meghalaya and the impact of such activity on species diversity and population structure on such forests. Data on firewood consumption and preferred firewood species, and impacts of firewood harvesting on species diversity and population structure were collected through household surveys and phytosociological studies respectively. The surveyed households showed high dependency on firewood and the consumption pattern varies with the family size. The preferred firewood species are those of hardwood trees such as Quercus spp., Lithocarpus spp., Castanopsis spp. and Myrica spp. Firewood extraction have negative impact on forests, resulting in decrease in species diversity and population of the preferred firewood species. Statistical analysis revealed that species richness and diversity and density differ significantly in protected and unprotected forests. Despite low per capita consumption of firewood and precautionary measures like regulated harvesting in the study area, firewood harvesting cannot be ignored as an important cause of forest degradation and biodiversity loss. More research into local ecological and cultural contexts and perceptions concerning costs and benefits can help devise sustainable management options, including alternative sources of fuel.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84809617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatoprotective potential of the plant extract was evident from the normalized biochemical parameters of hepatic injury like ALT, AST, ALP, GGT, SB, TGL, TC and TP along with the estimation of antioxidant status of the liver tissue (levels of Catalase, Superoxide dismutase, Glutathione and Malondialdehyde levels). The histopathological studies of liver samples showed recovery from Paracetamol-induced necrosis with almost normalized hepatic architecture in A. chelonoides extract-treated animals.

Br., are represented by one and two species in Bangladesh respectively (Siddiqui et al. 2007, Rahman 2018). In Bangladesh, these genera were known to contain the following three species: Arenga pinnata (Wurmb) Merr., Livistona chinensis (Jacq.) R.Br. ex Mart. and Livistona speciosa Kurz. (Siddiqui et al. 2007, Rahman 2018). Sangu-Matamuhuri Reserve Forest is one of the last strongholds of biodiversity in Bangladesh (Creative Conservation Alliance 2016). Sangu Reserve Forest (SRF hereafter) is located in the south of Boro Modok in Thanchi Upazila of Bandarban District, Bangladesh (Fig. 1). The actual floral diversity of SRF is still unknown. We conducted a field exploration at this remote forest during February 2019. SRF is a part of the Indo-Burma Biodiversity hot spot (Myers et al. 2000). SRF is the Sangu Wildlife Sanctuary (SWF), which was declared by the Forest Department of Bangladesh (Creative Conservation Alliance 2016). The climate of the region is tropical, with a mean annual rainfall of 2,666 mm. A dry and cool season occurs in that region from November to March, followed by a hot and sunny pre-monsoon season from April to May, and a warm, cloudy, and wet monsoon season from June to October (Khan 2015). During vegetation observation inside the forest, we found two species of unusual wild palms that are grown on hill slope sporadically associated with other vegetation and bearing fruits. Further, we reviewed the Siddiqui et al. (2007) and Rahman (2018) and confirmed these two palms are not reported from Bangladesh. Then the field photographs were sent to a palm specialist and finally examined as Arenga westerhoutii Griff. and Livistona jenkinsiana Griff. Hence, we reported these two species as new wild palms for Bangladesh. Direct observation has been done by a random walk inside the SRF (Fig. 1) and from the boat while moving in Sangu River. The field visit was from 20 th to 28 th February 2019. Clear photographs have taken for unknown plant species and also for the two unusual wild palms. We failed to collect any plant samples because they are grown on the top hills. Therefore, we took pictures with a telephoto lens. The photos are uploaded on a global database (inaturalist.org). The identification of these palms confirmed through field photographs that were examined by tropical Asian palm specialists.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77587832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
