ABSTRACT: Exploration of the vascular plant flora of the Canadian Arctic has been ongoing for almost two hundred years, yet substantial gaps remain in our floristic understanding of this large, rapidly changing and difficult-to-access ecozone. Detailed baseline information on thediversity and distribution of Arctic plants is urgently needed to understand the potential impacts of climate change on the region’s flora. In July 2014 we explored the rich flora along a Subarctic to Arctic gradient along the Coppermine River valley in western Nunavut, including Bloody Falls/Kugluk Territorial Park and Kugluktuk and vicinity. In this botanically underexplored area the treeline reaches its northern limit in Nunavut, just 40 km south of the Arctic coast. Study of our >1000 new and all previous collections of vascular plants document some 304 species in the area, comprising a mixture of boreal taxa (most at their northern limit), Arctic taxa (some at their southern limit), and amphi-Beringian taxa (some at their eastern limit). Among our collections are many first records for Nunavut (Allium schoenoprasum, Botrychium tunux, Draba lonchocarpa, Eleocharis quinqueflora, Eremogone capillaris subsp. capillaris, Festuca altaica, Polygonum aviculare, Salix ovalifolia var. arctolitoralis, S. ovalifolia var. ovalifolia, Stuckenia pectinata), mainland Nunavut (Carex gynocrates, C. livida, Cryptogramma stelleri, Juncus alpinoarticulatus subsp. americanus, Salix pseudomyrsinites), numerous northern and southern range extensions for boreal and Arctic species (Anthoxanthum arcticum, Arctostaphylos uva-ursi, Betula occidentalis, Carex adelostoma, C. capitata, C. lachenallii, C. norvegica, C. petricosa subsp. petricosa, Castilleja raupii, Draba simmonsii, Epilobium arcticum, E. davuricum, Festuca viviparoidea subsp. viviparoidea, Hordeum jubatum subsp. intermedium, Juniperus communis subsp. depressa, Linnaea borealis subsp. americana, Potamogeton gramineus, Rubus arcticus subsp. acaulis, Sagina nodosa subsp. borealis, Stellaria borealis subsp. borealis, Shepherdia canadensis, Taraxacum phymatocarpum, Utricularia intermedia, U. vulgaris) and many first records for the study area, which fill in gaps in the known distributions of Arctic species. Several species in the area reach their known northern limits in Nunavut in Kugluk/Bloody Falls Territorial Park, a protected site. The many floristic novelties identified for the study area underscore the fact that there remains much to learn about vascular plant biodiversity in Canada's low Arctic.

ABSTRACT: Core functions of museums are the collection, long-term preservation, stewardship and curation of specimens, facilitating access to these specimens – physically and digitally – for research purposes, and engaging and educating the public about the world around them. Biological and geological specimens from the Arctic and their associated collection data are a diverse, important and increasingly valuable component of the polar information spectrum. Natural history specimens are data themselves, documenting the distribution of species in time and space; they serve as vouchers for datasets, allowing future workers to go back to original material to confirm or revise identifications; and they are also sources of new data (morphology, anatomy, toxicology, genetic information). The development of international standards (e.g., the Darwin Core) and best practices to facilitate interoperability and sharing of biodiversity occurrence data has allowed
institutions to easily share their collection data on their own websites, and through national, regional and international indexing portals such as the Global Biodiversity
Information Facility (GBIF). This successful example of data management and interoperability could serve as a model for the polar community. The research and public
outreach potential of Arctic collections data is enormous, but a challenge that many natural history museums are facing is the massive task of databasing and imaging the collection so that it may be mobilized, discovered, shared and used. The Canadian Museum of Nature, founding member of the international Arctic Natural History Museums Alliance, houses the largest – and continually growing – collection of natural
history specimens from the Canadian Arctic, with ca. 260K Arctic specimens (including >550 type specimens). Some 154K of our specimens from north of 60 degrees are digitized and freely accessible online (http://collections.nature.ca/en/Search) and shared through GBIF. Natural history museums need to be more involved in Arctic science discussions to raise awareness and increase usage of their rich data resources.

Bird ringing has therefore been part of this analysis. Indian Skimmer and other riverine birds like the Black-bellied Tern Sterna acuticauda, Little Tern Sternula albifrons, Small Pratincole Glareolalactea, Black-winged Stilt Himantopus himantopus, the River Lapwing Vanellus duvaucelii, Great Thick-knee Esacus recurvirostris and the River Tern Sterna aurantia, totaling 203 birds, were ringed from May to July 2018. The birds were marked with numbered metal ring and the colored flag (white flag with alpha numeric number engraved in red colour). In January 2019, we observed that a few of the ringed skimmers have started returning to the ringing sites in Sanctuary. The tome “Important Bird Areas in India” was released in October 2004 by the Minister of Environment and Forests, Government of India; and later it was released in many of the states and distributed to the Forest Department officials and the individuals who had contributed during the IBA selecting proces

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Editor's Notes
At the end of the trip we will explore and collect plants in and around the community of Kugluktuk, including along the Arctic coast.
Reported in FNA for Nuvavut, but source of record unknown.
In Nunavut this taxon was known previously only from northern Ellesmere Island (Aiken et al. 2007; Aiken and Darbyshire 1990); our collections are the first ones from mainland Nunavut. In adjacent Northwest Territories, it is known from Tuktut Nogait National Park and vicinity (Saarela et al. 2013a) and Arctic Yukon further west (Aiken and Darbyshire 1990, as Festuca vivipara subsp. glabra Fred.).
In Nunavut the taxon is recorded only from Akimiski Island
Reported from Big Bend Area of coppermine by Cody et al. and SW Nunavut – new to *Arctic* ecozone.
Earlier records from Bathurst Inlet *NOT* included in FNA.
Our collections of this species are the first ones from western Nunavut and represent a northern range extension from the nearest sites along the eastern arm of Great Bear Lake (Cody and Britton 1989; Porsild and Cody 1980). Elsewhere in Nunavut it is known from two Arctic mainland collections: Thelon River ca. 28 mi SW of Beverly Lake, 64°36’N, 100°30’W, 11 July 1960, E. Kuyt 62, CAN-561540, mapped in {Porsild, 1980 #1444@@author-year}; east of South Bay of Griffin Lake, Reading s.n., DAO [east side of Queen Maud Bird Sanctuary, east side] (Cody 1996); and the Belcher Islands (Sanikiluaq, Consaul et al. 3875, CAN-599928). There are non-Arctic Nunavut records from southern Nunavut adjacent to the Manitoba border (Nueltin Lake, Harper 2378, CAN-3849) (Hauke 1993; Porsild and Cody 1980) [not mapped in Cody and Britton (1989)] and Akimiski Island (Blaney and Kotanen 2001). All of the Nunavut collections are along the northern edge of this primarily boreal species’ range. It also reaches the Arctic in the Anderson River Delta (Grizzly Bear Creek, 69°42’N, 129°W, 24 August 1959, T.D. Barry 457, CAN-287853) and on the north slope of Alaska (specimens at ALA; Porsild and Cody 1980).
