“…Take, for example, desert plants, which grow under extreme temperatures, higher light intensity, and low water conditions, or plants which grow at high altitudes where the air is thinner and oxygen is less abundant (Figure 2A,B). 95‐97 Further temperature tolerance mechanisms may be gleaned from Antarctic plants, or plants that have survived dramatic events such as forest fires and prolonged flood 98‐100 .

Planet Earth has experienced many dramatic atmospheric and climatic changes throughout its 4.5-billion-year history that have profoundly impacted the evolution of life as we know it. Photosynthetic organisms, and specifically plants, have played a paramount role in shaping the Earth's atmosphere through oxygen production and carbon sequestration. In turn, the diversity of plants has been shaped by historical atmospheric and climatic changes: plants rose to this challenge by evolving new developmental and metabolic traits. These adaptive traits help plants to thrive in diverse growth conditions, while benefiting humanity through the production of food, raw materials, and medicines. However, the current rapid rate of climate change caused by human activities presents unprecedented new challenges to the future of plants. Here, we discuss the potential effects of modern climate change on plants, with specific attention to plant specialized metabolism. We explore potential avenues of future scientific investigations, powered by cutting-edge methods such as synthetic biology and genome engineering, to better understand and mitigate the consequences of rapid climate change on plant fitness and plant usage by humans.

Research Question To what extent is local flora influenced by ornithogenic soil biochemical-composition in the South Sandwich Islands, with special attention given to Zavodovski, and what are the down-stream effects on the geology of the islands? Hypothesis Areas supplied by fluvial run-off from penguin colonies, especially cr&circ;eches, host the most productive and species rich floral landscapes, even after controlling for geothermal activity.

“…As mudanças climáticas para a Antártica, especialmente o aumento das temperaturas, resulta em maior disponibilidade de água e levará a (i) aumento das taxas de colonização local e de longa distância, e (ii) expansão da população em escala local, levando a (iii) maior diversidade terrestre, biomassa e complexidade trófica, (iv) estrutura ecossistêmica mais complexa (Singh, Singh, & Khare, 2018). Para o caso da geleira Collins, Simões et al (2015) indicam sua retração nas últimas décadas e Rückamp et al (2011) indicam o quase total desaparecimento da geleira para os próximos 200 anos.…”

O objetivo do artigo é avaliar a variação de área e localização dos campos de musgos na Península Fildes, Antártica, utilizando a técnica de NDVI e imagens LANDSAT, para o período 1986 - 2016, frente a cenários de mudanças climáticas. A técnica de NDVI foi aplicada em 7 datas de imagens LANDSAT e os produtos foram avaliados pelo índice Kappa. A área de vegetação aumentou de 1,5 para 2,7 km² no período. Os resultados do índice Kappa indicam a variação entre 0,81 a 0,93 de acurácia, com mais de 70% das áreas mapeadas indicadas acima de 0,1 (área muito provável de vegetação). Os maiores campos de musgos (83% daqueles de maior dimensão) se localizam na porção orientada para o estreito de Drake e estão associados à umidade e vento proveniente do oceano. Há maior quantidade de matéria orgânica e formação de alagados nos paleovales em “U” voltados para o Drake, contribuindo para a fixação da vegetação. Os campos de musgos continuarão a aumentar ou haverá modificação da sua localização diante de cenários de retração da geleira local Collins e o consequente aumento da disponibilidade de água líquida e sedimentos no ambiente proglacial e periglacial.
