The source of this slab in Bathtub Gorge is the surface of a thick red sandstone with pseudomorphs of gypsum desert roses, which is interpreted as a Gypsid paleosol of the Muru pedotype. On this “snakes and ladders slab” (nicknamed for snake–like Aulozoon and ladder–like Phyllozoon), four specimens of Dickinsonia are poorly preserved above rounded terminations of Aulozoon. Aulozoon also has been discovered in five other thin sections cut below Dickinsonia basal surfaces, and in one case it is attached to Dickinsonia. Aulozoon has a high width to thickness ratio (14 ± 0.7), even after accounting for burial compaction. Burrows this much wider than high are unknown and would be mechanically difficult for a burrower. Stronger objections to a burrow interpretation come from taper of Aulozoon to half its width and local lateral crimping. Unlike deep sea tube worms, animal or algal stolons, Aulozoon is not cylindrical and lacks a finished inside wall outline. Outer finished wall grading inwards to sandstone fill of Aulozoon scoliorum is most like a fungal rhizomorph with loose internal hyphae, and this biological interpretation is supported by growth within a paleosol with desert roses.\u0000सारांश \u0000औलोज़ून स्कोलियोरम दक्षिण ऑस्ट्रेलिया के रॉन्सले क्वार्टजाइट के नीलपेना सदस्य से एक बड़े स्लैब से भलीभांति जाना जाता है और  एक एडियाकरन पुरासमुदाय का प्रतिनिधित्व करता है, जिसमें फ़िलोज़ून हैंसेनी, डिकिन्सोनिया कोस्टाटा, एस्पिडेला टेरानोविका, स्यूडोरहिज़ोस्टोमाइट्स हाउचिनी और सोमाटोहेलिक्स सिनुओसस शामिल हैं। बाथटब गॉर्ज में इस स्लैब का स्रोत जिप्सम डिज़र्ट रोजेस के स्यूडोमोर्फ्स के साथ एक मोटे लाल बलुआ पत्थर की सतह है, जिसकी मुरु पेडोटाइप के जिप्सिड पेलियोसोल के रूप में व्याख्या की गई है। इस \"साँप और सीढ़ी स्लैब\" पर (साँप-जैसे औलोज़ून और सीढ़ी-जैसे फ़िलोज़ून के लिए उपनाम), डिकिन्सोनिया के चार नमूने औलोज़ून के गोल सिरे के ऊपर खराब रूप से संरक्षित हैं। औलोज़ून को पाँच अन्य थिन सेक्शन में भी खोजा गया है, डिकिन्सोनिया बेसल सतहों के नीचे, और एक मामले में यह डिकिन्सोनिया से जुड़ा हुआ है। संरक्षण संघनन के लिए लेखांकन के बाद भी औलोज़ून में मोटाई चौड़ाई का अनुपात (14± 0.7) अधिक है। ऊंचाई की तुलना में इतनी चौड़ी बर्रो अज्ञात हैं और  बर्रो बनाने वाले के लिए यंत्रात्मक रूप से कठिन है। औलोज़ून के टेपर से इसकी आधी चौड़ाई और स्थानीय पार्श्व ऐंठन से एक बर्रो की व्याख्या के लिए प्रबल आपत्तियां हैं। गहरे समुद्र ट्यूब वर्म, जन्तु या शैवालीय स्टोलन के विपरीत, औलोज़ून बेलनाकार नहीं है, और आंतरिक भित्ति की पूर्ण रूपरेखा की कमी को दर्शाता है। औलोज़ून स्कोलियोरम के बलुआ पत्थर के अंदर की ओर बाहरी तैयार दीवार की ग्रेडिंग ढीले आंतरिक हायफी के साथ एक कवक राइज़ोमॉर्फ की तरह है, और यह जैविक व्याख्या एक पेलियोसोल के भीतर डिज़र्ट रोजेस के साथ वृद्धि द्वारा समर्थित है।","PeriodicalId":383463,"journal":{"name":"Journal of Palaeosciences","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125946899","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 review provides an important compendium of evidences for Carthamus and related species in different geographical locations of the world through the ages as well as in the modern era. The archaeological records so far indicate that Carthamus sp. was established in northwestern India during the chalcolithic culture around 3rd–2nd millennium BCE in Indian subcontinent and then distributed to the other regions. However, the origin and domestication of the crop has been recorded from the Middle East around ~4000 years ago. Carthamus tinctorius L. (safflower) is the cultivated representative of this genus and has great economic importance as it is used for making different varieties of oil or dyes, today and in the past.\u0000सारांश\u0000यह लेख वनस्पति और पुरातात्विक साक्ष्य की वर्तमान स्थिति जो कि भारतीय उपमहाद्वीप और दुनिया के अन्य भागों में कार्थमस एसपी की उत्पत्ति, वितरण, आनुवंशिक विविधता और खेती को धारण करने की समीक्षा करता है। यह समीक्षा युगों के साथ-साथ आधुनिक युग में दुनिया के विभिन्न भौगोलिक स्थानों में कार्थमस और संबंधित प्रजातियों के साक्ष्य का एक महत्वपूर्ण संग्रह प्रदान करती है। अब तक के पुरातात्विक आलेखों से संकेत मिलता है कि कार्थमस  एसपी पश्चिमोत्तर भारत में तीसरी-दूसरी सहस्राब्दी ईसा पूर्व के आसपास चालकोलिथिक संस्कृति के दौरान भारतीय उपमहाद्वीप में स्थापित किया गया था और फिर अन्य क्षेत्रों में फैला। यद्यपि, लगभग 4000 वर्ष पूर्व मध्य पूर्व से फसल की उत्पत्ति को आलेखित किया गया है। कार्थमस टिंक्टरियस एल (कुसुम) इस जीनस का खेती वाला प्रतिनिधि है और इसका एक बड़ा आर्थिक महत्व है क्योंकि इसका उपयोग आज और अतीत में विभिन्न प्रकार के तेल या रंग बनाने के लिए किया जाता है।","PeriodicalId":383463,"journal":{"name":"Journal of Palaeosciences","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129886366","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 attempt to integrate sampling of pollen–vegetation spectrum through Crackles Protocols for vegetation surveys, at three spatial zones with intervals of 0–10 m (A), 10–100 m (B) and 100–1000 m (C) at Shaheed Chandra Shekhar Azaad Bird Sanctuary in Uttar Pradesh with tropical dry deciduous forest, is a maiden approach. In these studies, the standard vegetation survey around the pollen surface sampling sites is prerequisite for quantifying pollen–vegetation relationship in modern analogues of the past. The underlying theory of this approach is based on the fact that the relative pollen productivity (RPP) is constant in space and time within a region or biome. The floristic survey of the sanctuary is integral to this pilot study, Crackles Bequest protocol, and is intrinsic to run the Extended R–Value (ERV) model for obtaining estimates of relative pollen productivities (RPPs) for quantitative palaeoecological interpretations from tropical to subtropical forest covers in northern India. The modern pollen assemblage from surface sediment samples established the dominance of Poaceae pollen, along with those of Acacia, Albizia and Mimosa species. The multivariate principal component analysis (PCA), applied to quantify the data on the survey of different vegetation communities revealed that out of the four identified vegetation communities, community D consisted of herbaceous patches including Ageratum, Parthenium, Rumex, Tephrosia, Eclipta alba, Oxalis, Cannabis and Launea, community B mainly comprised of tree taxa like Terminalia, Barringtonia and Pongamia, whereas the communities A and C represented mixed vegetation comprising of trees, shrubs and herbs. The present maiden analysis through the Crackles Bequest protocol method served as a preliminary step to establish the quantitative ‘pollen–based’ vegetation reconstruction in the Gangetic Plains of Central India and is expected to serve as a model for similar studies in other regions.\u0000सारांश\u0000अतीत के भू-आवरण को चित्रित करने वाले वनस्पति पुनर्निर्माण की सटीकता पराग उत्पादन, फैलाव और उनके मात्रात्मक जमाव के सावधानीपूर्वक विश्लेषण पर आधारित है। शहीद चंद्र शेखर आज़ाद (एससीएसए) पक्षी अभयारण्य, मध्य गंगा मैदान से 0-10 मीटर (ए), 10-100 मीटर (बी) और 100-1000 मीटर (सी) के अंतराल में तीन स्थानिक क्षेत्रों में, वनस्पति सर्वेक्षण के लिए क्रैकल्स प्रोटोकॉल के माध्यम से पराग-वनस्पति स्पेक्ट्रम के नमूने को एकीकृत किया गया। यह भारत के उष्णकटिबंधीय शुष्क पर्णपाती वन से किया गया प्रथम प्रयास था। पुरावनस्पति एवं पुरापारिस्थितिकी को समझने के लिए पराग-वनस्पति संबंधों को निर्धारित करने की आवश्यकता है। आधुनिक सादृश्य को स्थापित करने के लिए पराग सतह नमूना स्थलों के आसपास मानक वनस्पति सर्वेक्षण अनिवार्य है। इस दृष्टिकोण का अंतर्निहित सिद्धांत इस तथ्य पर आधारित है कि सापेक्ष पराग उत्पादकता (आरपीपी) एक क्षेत्र या बायोम में स्थानिक व लौकिक रूप से स्थि","PeriodicalId":383463,"journal":{"name":"Journal of Palaeosciences","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124121119","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}

Such surveys are particularly important in ecologically sensitive transitional climatic zones but logistically difficult terrains, where meteorological data is scarce and minor changes in climatic parameters can have unanticipated consequences for the local ecosystem. The current research is focused on one of such climate-sensitive areas, in the northwestern Himalaya. A binary question-based survey (interview) was conducted in the high-altitude, cold desert region – Ladakh, which covered all the five subdivisions of the union territory. According to the climate perception data, the majority of respondents are aware of climate change or global warming regardless of age, gender, and background. The exponential growth in tourist inflow over the last two decades (attributed to ‘war tourism’) equates with the increasing number of vehicles and is well perceived by the locals. Approximately 86 percent of respondents believe that humans have had a negative impact on the environment. They appear to be quite optimistic about curbing the effects of climate change, with approximately 91 percent willing to participate in mitigation efforts. The results of this study show an overall agreement between people’s perceptions of climate change and the scientific evidence of these changes. These findings are eventually intended to serve as an important parameter in developing adaptation and mitigation strategies in this ecologically sensitive and vulnerable region.","PeriodicalId":383463,"journal":{"name":"Journal of Palaeosciences","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737059","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 monsoon has provided the means of survival to many civilizations, besides sculpting the drainages and the paleogeography of the subcontinent. The evolution of the Himalayas has played a critical role in the evolution of the summer monsoon, which gave life to rivers, crops and human settlements.
