“…Algal community structure is influenced by specific climate condition, particular soil type and specific vegetation of the locality (Bohlen & al., 2001). Canopy cover formed by the higher plants along with the physical and chemical characteristics of the soil affected the composition of the algal population in the forest floor (Bakieva & al., 2012). Positive influences of nutrients, moisture content and the degree of soil compaction have been observed on the growth of soil algae (El-Gamal & al., 2008).…”

In the present study, soil algal community inhabiting in two different forest types i.e., pine forest and subtropical broadleaf forest (Mawphlang sacred grove) in East Khasi Hills District of Meghalaya have been investigated. Light availability to the forest floor and soil physico-chemical parameters were examined. A total of 124 taxa of soil algae were recorded from both the forests. Members from Chlorophyta, Xanthophyceae, Eustigmatophyceae contributed the most (72%-80%). Mawphlang sacred grove was characterised by more abundance of Cyanobacteria (21%) and less diatoms (2%), while in pine forest diatoms abundance was high (20%) and less Cyanobacteria (13%). Algal species composition differed significantly between the two forest types. Correlation between species diversity with light and soil characteristics indicated that vegetation along with pH, moisture content, organic carbon and nitrogen played important role in determining the composition of algal community. lkjka 'k orZ eku v/;;u es a ] es ?kky; ds iw ohZ [kklh ftys es a phM+ ou o miks ".kdfVca /kh; pkS M+ s IkRrs okys nks iFkd ouks a es a ¼ekoQyka x ifo= ou½ eǹk 'kS oky oxZ dh foos puk dh xbZ gS A ou lrg es a iz dk'k miyC/krk ,oa eǹk HkkS frd jlk;u iS jkehVj dh ta kp dj yh xbZ gS A nks uks a ouks a ls eǹk 'kS oky dk dq y 124 VS Dlk vfHkys f[kr fd;k x;k gS A Dyks jks QkbVk] tS a Fkks Qkblh] b;w LVhXekes Vks Qk;lh vo;o dk lokZ f/kd ek=k ¼72%-80% ½ jgkA ekoQyks a x ds ifo= ou es a lkbuks cs DVs fj;k dk vf/kd ek=k ¼21%½ ,oa Mk;Ve dh de ek=k ¼2%½ tka ph xbZ A tcfd phM+ ds ouks a es a Mk;Ve dh vf/kd ek=k ¼20%½ ,oa lkbuks cs DVs fj;k dh de ek=k ¼13%½ tka ph xbZ A nks ouks a ds iz dkj es a 'kS oky tkfr dk la ;ks tu dkQh vyx gS A iz dk'k vkS j eǹk dh fo'ks "krkvks a ds lkFk tkfr;ks a dh fofo/krk ds chp la ca / kks a ls ba fxr feyrk gS fd ih,p-vknz Z rk dh ek=k] tS fod dkcZ u ,oa ukbVª ks tu ds lkFk ouLifr us 'kS oky oxZ ds la ;ks tu es s a egRoiw .kZ Hkw fedk fuHkkbZ gS A es ?kky; dh iw ohZ [kklh igkfM+ ;k¡ ds cz kW MyhQ ifo= ou vkS j phM+ ouks a es a eǹk 'kS oky dh fofo/krk vkS j ikfjfLFkfrdh lh-,e-fMjcks UkZ ,oa ikfi;k jkekuq te

“…Since then, a number of new species have been attributed to the genus (e.g., [9][10][11][12][13][14][15][16][17]). To date, according to the Algaebase (https://www.algaebase.org; accessed on 11 August 2023), the genus Luticola includes 264 species that are widely distributed throughout these regions of the world: Eurasia [18][19][20], Europe [8], South America [11,21], islands in the southern Indian Ocean [9], Africa [17], Madagascar [12], Asia [10,22], and Antarctica [23][24][25].…”

Diatoms inhabit different aquatic and non-aquatic environments, including soils. The naviculoid genus Luticola is widespread in various habitats and accounts for 264 species that are only based on morphological and morphometric characteristics. These parameters can greatly vary during the life cycle, making the species very similar to each other and complicating their unambiguous identification. During a study on soil algal diversity in the Russian Far East (Jewish Autonomous Region), we isolated a strain of naviculoid diatom and examined it using an integrative approach (phylogenetic, morphological, ultrastructural data, and life cycle). Phylogenetic analyses, based on chloroplast rbcL gene data, showed affinity of the new strain with the genus Luticola. Our alga shares morphological features typical of the genus members but differs from them by having valves with a larger width and hook-shaped external proximal raphe ends deflected to the side opposite the stigma. It was revealed that the strain reproduces via two types of sexual reproduction—isogamy and cis-anisogamy. Based on these phenotypic traits, we described the new isolate as Luticola tenera sp. nov.

“…Additionally, we were able to distinguish four different sites (12,7,4,2) within those samples, suggesting that species' composition of the communities is quite different from each other and that the composition generally does not change much over time (Figure 3.2). Indeed, site 12, a deciduous forest located on marls, had repeatedly very high abundances of Humidophila Additionally, we examined which factors were responsible for the (dis)similarities between the different communities over the sampling period.…”

Chapter 5: Ecological optima and ranges of common diatom species occurring on soils are defined for pH and soil moisture and compared with previously established autecological values. For this chapter, several datasets are merged including the data gathered in Chapter 2, in order to obtain more robust results.Chapter 6: The potential for the Phillips sampler, a time-integrated mass-flux sampler, is explored to provide a representative sample of the diatom assemblage of a whole storm run-off event. Its representativeness is evaluated by comparing the diatom community composition of the sampler to the composite community collected by automatic samplers for three events. 11 CHAPTER 2 STUDY AREA AND METHODOLOGY 2.1 STUDY AREA Two distinct geomorphological regions dominate the landscape of Luxembourg (Figure 2.1). The southern half of the country, the Gutland region, is characterized by deep valleys cut into the Luxembourg sandstone, alternated with large valleys located in the Keuper marls, while in the northern Oesling (or Eislek) region, Devonian bedrock and deeply incised Vshaped valleys dominate. Altitudes in Luxembourg vary from 140 to 440 m.a.s.l. in the Gutland and from 225 to 559 m.a.s.l. in the Oesling (Cammeraat et al., 2018). Lying in the contact zone between these two contrasted regions, the Attert River basin (249 km²; 49°46′13.0″ N, 5°59′9.2″ E) is representative of the wider physiographic setting of Luxembourg. The Gutland covers 76% of the total Attert basin area and extends through the middle and southern part of it, whereas the Oesling, situated in the north, represents 24% of the basin (Cammeraat et al., 2018). The basin can be divided into three distinctive physiogeographic units. The first unit, the so-called Luxembourg plateau, is located in the southern part of the Attert River basin and mainly consists of Luxembourg sandstone locally covered by marls, and Luxembourg red sandstone ("Bundsandstein"). Land use in the area is dominated by forests and farmland supported by sandy to clayey soils such as podzols, luvisols, stagnosols, cambisols and regosols. The centre of the basin, called the marly depression, represents 68% of the total basin area. It comprises of very clayey soils (vertisols, planosols, cambisols and stagnosols) that support mainly forests and grassland (Cammeraat et al., 2018). The lithology of the third unit (i.e. the Oesling) mainly consists of schists and phyllades. The regosols and cambisols present in the northern part mainly have a silty soil texture and are mixed with gravels, while forests make up the dominant land use in that area. Farmland in the basin is primarily used for growing corn, wheat and rapeseed, while grasslands are predominantly used for cattle grazing. European beech (Fagus sylvatica L.) and spruce (Picea abies L.) dominate the forested areas. The climate regime of the basin is semi-oceanic.Due to its complex physiogeographic characteristics, the basin has been the focal point of many (eco)hydrological studies, including studies on hydrological processes, ...
