“…These values indicate that the present tropical deciduous forest in a species diverse system. The concentration of dominance (Simpson's index) in the present study is within the reported range 0.21-1.0 for tropical forests by several workers (Kumar et al 2010;Visalakshi 1995;Sahu et al 2012c). The evenness index values fall within the range between 0.64-1.34 in other forests (Lalfakwma et al 2009;Sahu et al 2012a).…”

Premavani D, Naidu MT, Kumar OA, Venkaiah M. 2017. Diversity and distribution of tree species in tropical forests ofNorthcentral Eastern Ghats, India. Asian J For 1: 27-32. The diversity and distribution of tree species were studied in three 1 ha sites oftropical forests in the northcentral Eastern Ghats of India. The phytosociological data from forest sites were analyzed quantitatively todetermine the basal area, species diversity, richness and stand density. A total of 1,507 individuals of 104 plant taxa, pertaining to 82genera under 41 families were enumerated at â‰¥15 cm gbh using belt transects (5 m Ã— 1000 m). Tree stand density varied from 371-660individuals per ha while average basal area ranged from 14.54 â€“ 46.51 m2 ha-1. Shannon-Weiner Index (H') ranged from 0.97-0.98,Equitability or evenness index ranged from 0.70-0.79 and Margalef richness index ranged from 10.54 â€“ 10.82. The most dominantfamilies were Rubiaceae, Euphorbiaceae, Fabaceae, Moraceae, and Verbenaceae. Our results suggest further development of forestmanagement and biodiversity conservation in Eastern Ghats region.

“…The dominant therophytes, cryptophytes and chamaephytes altogether constituted 51.61% of the life forms proportion. Therophytes showed the maximum divergence of the normal spectrum; a similar phytoclimatic association had also been reported by other workers for different tracks of vegetation (da Costa et al 2007;De Mera and Vicente Orellana 2007;Sahu et al 2012;Ceschin and Caneva 2013;Raju et al 2014;Jakhar 2015;Yifru et al 2015;Hamid and Raina 2019;Das et al 2020;Zeb et al 2020).…”

“…The results also agree with those of Sher and Khan (2007), who also stated that therophytes and nanophanerophyes were characteristics of subtropical habitats. Sahu et al (2012) discovered that therophytes and nanophanerophytes predominated in Odisha, India. Structurally and floristically the sub-tropical dry forests are less complex than wet forests, comprising about half or less of the tree species of the wet forest (Castro-Esau and Kalacska 2008).…”

Abstract. Sen UK, Bhakat RK. 2021. Quantitative evaluation of biological spectrum and phenological pattern of vegetation of a sacred grove of West Midnapore District, Eastern India. Asian J For 5: 83-100. Sacred groves, small forests patches devoted to deities and ancestral spirits, are classic examples of community-based, culturally aware, natural resource management. To indigenous groups that care for them, display rich biodiversity, and provide ecological services to local groups that have sustained the environment over the years, sacred groves have cultural and spiritual significance. This studied sacred forest hosts 312 plant species belonging to 257 genera under 78 families of 34 orders according to APG IV. Poales, 73, 23.40% and Poaceae, 48, 15.38% were the dominant order and family. Therophytes, cryptophytes and chamaephytes constitute a higher percentage 16.81%, 3.62% and 3.18% respectively than the normal spectrum exhibiting “thero-crypto-chamaephytic” phytoclimate. Leaf size spectra showed that the plant with leptophyll, 83, 26.60% and ovate, 59, 18.91% type's leaf lamina were dominant. The findings may have a heuristic value in developing future monitoring schemes and assessing the effects of global change in this varied but poorly studied area.

“…The comparative percentage of dissimilar life form to an existing flora in a specific region or spot is called its biological spectrum [ 29 ]. The biological spectrum reveals how plants have changed to cope with their micro- and macro-climates, and it contains significant physiognomic traits that are frequently used in vegetation research [ 30 , 31 ]. The most common group of biological forms were therophytes, followed by hemicryptophytes and geophytes.…”

Weeds are a major threat to agriculture and horticulture cropping systems that reduce yield. Weeds have a better ability to compete for resources compared to the main crops of various agro-ecosystems and act as a major impediment in reducing overall yield. They often act as energy drains in the managed agroecosystems. We studied weed infestation for five different agro-ecosystems in the part of Indian Western Himalayas represented by paddy, maize, mustard, apple and vegetable orchards. Systematic random sampling was done to record flowering phenology and diversity of weeds during the assessment period 2015–2020. We recorded 59 weed species, taxonomically distributed among 50 genera in 24 families. The Asteraceae family has the most species (15% species), followed by Poaceae (14% species), and Brassicaceae (12% species). The Therophytes were the dominant life form followed by Hemicryptophytes. The majority of the weeds were shown to be at their most blooming in the summer (predominantly from June to July). The Shannon index based diversity of weeds ranged from 2.307–3.325 for the different agro-ecosystems. The highest number of weeds was in the horticulture systems (apple > vegetable) followed by agriculture fields (maize > paddy > mustard). Agriculture and horticulture cropping systems were distinguished using indicator species analysis, which was supported by high and significant indicator values for a number of species. Persicaria hydropiper, Cynodon dactylon, Poa annua, Stellaria media, and Rorippa palustris had the highest indicator value in agriculture cropping systems, while Trifolium repens, Phleum pratense, and Trifolium pratense had the highest indicator value in horticulture cropping systems. We found that eleven weed species were unique to apple gardens followed by nine in maize, four in vegetables, two in mustard and one in paddy fields. Spatial turnover (βsim) and nestedness-resultant components (βsne) of species dissimilarity revealed dissimilarity lower than 50% among the five cropping systems. The study is expected to assist in formulating an appropriate management strategy for the control of weed infestation in the study region.
