“…Air pollution is a global problem and has negative effects on human, animal and plant health (Kanawade et al, 2010). Pollutants emitted into the atmosphere are deposited at the Earth's surface where they accumulate in soil, sediment, and biota of terrestrial and aquatic ecosystems (Schröder et al, 2016).…”

“…Transportation and industry produce emissions such as carbon dioxide and nitrogen oxides that contribute to air pollution in urban areas. Pollution causes ecological effects such as the greenhouse effect, harm to plant and animal health and temperature stress (Kanawade et al 2010). It is damaging to urban biodiversity because several species have become more sensitive to environmental stress from pollution and habitat fragmentation (Uttara et al 2012;Szlavecs et al 2011).…”

Bryophytes are nonvascular plants that have simple structures that are sensitive to environmental changes, and they can, therefore be used as indicators of air quality. The presence of bryophytes in disturbed urban ecosystems, such as residential and industrial areas, indicates that their structures have adapted to survive in such areas. The objective of this study was to compare the bryophyte diversity and air quality indices between a residential area and an industrial area in Jakarta. The research was conducted in the Bona Indah residential area in South Jakarta and the Jakarta Industrial Estate Pulogadung (JEIP) urban forest. Sampling was carried out using the transect method in the residential area and the quadratic method in the urban forest on three different substrates, namely rocks or concrete, soil and tree trunks. The percentage of the epiphytic bryophyte cover was measured using a 10 × 10 cm subplot. Voucher specimens were stored at the Herbarium UI DEP and Herbarium IPB. Twenty-one species of moss and three species of liverwort were found in the two locations. Bryophytes were found on all the substrates in the residential area, but in the urban forest, they were found only on tree trunks and rock/cement substrates. Based on the Shannon–Wiener Index, although both locations had moderate bryophyte diversity, the residential area’s bryophyte diversity was higher than that of the urban forest. The index of atmospheric purity in the residential area was 4.3, indicating a high level of pollution, and it was 0.3 in the urban forest, showing that it was also very polluted.

“…Heavy metals are amongst the most hazardous pollutants to living organisms due to their high toxicity and persistence in the environment [1][2][3][4] . Multiple studies showed that heavy metals damage the cell membrane system and negatively affect plant development, growth, and reproduction [5][6][7][8] , generate reactive oxygen species (ROS) 9,10 , and may alter the structure of essential plant biomolecules [11][12][13][14] .…”

Bryophytes’ remarkable capacity to tolerate extreme abiotic conditions allows us to enhance our understanding of the diversity of molecular mechanisms involved in plant stress response. Here, we used next generation sequencing to study DNA methylation and gene expression changes in plants from four populations of the metallophyte moss Scopelophila cataractae experimentally exposed to either Cd or Cu. These populations previously showed differences in tolerance to both metals, so here, we aimed at uncovering the molecular basis of this phenotypic differentiation. We found no evidence of genetic differentiation among the populations studied. The epigenetic data, however, showed limited but significant population-specific changes in DNA methylation in response to both metals. Exposure to acute Cu stress in the laboratory led to the downregulation of genes involved in heavy metal tolerance in both populations regardless of their tolerance level, but this response was quantitatively higher in the most tolerant. We propose that chronic exposure to varying levels of heavy metals in the field led to potentially non-genetically-based intraspecific differentiation for heavy metal tolerance in S. cataractae. The most tolerant plants invested more in constitutive protection and were more efficient in entering a conservative state when faced with acute Cu stress.
