“…It is noteworthy that Conocarpus erectus (Buttonwood), a mangrove associate, also occurs in this ecoregion (Ochoa-Gómez et al, 2021). However, this species does not satisfy the criteria to be a true mangrove as defined by Tomlinson (2016) and is not listed by other studies (e.g.…”

Mangroves of the Warm Temperate Northeast Pacific is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of the South-Californian Pacific and the Gulf of California. The mapped extent of the Warm Temperate Northeast Pacific mangrove province in 2020 was 1,810.4 km², which represents 1.5% of the global mangrove area. There are three species of true mangroves that characterize the biota: Rhizophora mangle, Laguncularia racemosa and Avicennia germinans. These mangroves all grow on a southeast-northwest latitudinal axis, from greater to lesser structural complexity due to less favourable temperature conditions and availability of freshwater with increasing distance from the tropical zone. The main threats to the mangrove ecosystem in this region derive from changes in hydrological and sediment regimes, almost always related to the development of local infrastructure, such as canals and roads or the construction of upstream dams. Another emerging threat is the increased incidence of hurricanes in the region, which have affected large areas mainly in the last five years. Based on our analysis, it has been estimated that the Warm Temperate Northeast Pacific mangroves have expanded their coverage by 12.46 % since 1970. Nevertheless, the net area change has been -8.5 %. If this trend persists, it is anticipated that there will be 8.2 % reduction in coverage to 2055. Based on the IPCC RCP8.5 high sea-level rise scenario, it is estimated that the Warm Temperate Northeast Pacific mangroves will experience significant submergence of approximately 26.6 %, by the year 2060. Additionally, ~3 % of the mangrove ecosystem in the province is undergoing degradation currently, and this percentage is expected to increase to 8.7 % within the next 50 years. These estimated are based on a vegetation index decay analysis. The Warm Temperate Northeast Pacific mangrove ecosystem is currently assessed as Near Threatened (NT).

“…Conocarpus erectus, a plant with spherical flowers, is common in tropical and subtropical areas of the world (5). The cultivation of C. erectus in Iran's south and southwest has received widespread approval due to its superior pruning capabilities and high survival rate (6). Studies on C. erectus use in medicine have demonstrated its anti-inflammatory, antimicrobial, and anticancer properties.…”

Background: The Conocarpus extract possesses antioxidant, antibacterial, and anti-inflammatory properties, which may prove to be beneficial in the healing of skin wounds. Objectives: This study investigated the protective effects of Conocarpus leaf extract on HSF-PI 17 fibroblast cells against the harmful effects of UVB radiation. Methods: After culturing the cells, the MTT assay was employed to evaluate the cytotoxicity of the Conocarpus extract. The cells were divided into three groups: The control group, the group receiving radiation only, and the group receiving radiation along with the Conocarpus leaf extract. Trypan blue staining was utilized to quantify the count of viable cells. The level of reactive oxygen species (ROS) production was determined by measuring the intensity of fluorescence color. Real-time PCR was utilized to evaluate gene expression, while Western blotting was employed to determine protein expression. Results: Conocarpus extract had no toxic effects on HSF-PI 17 cells at doses ranging from 0.01 to 10 g/mL. Exposure to UVB radiation led to a notable rise in the production of ROS and a considerable decline in cell growth rate compared to the control group (P < 0.05). In the third group, the Conocarpus extract significantly moderated the reduction in growth and production of ROS compared to the second group (P < 0.05). TGF-β and SMAD2/3 gene expressions, as well as collagen protein levels, were significantly lower in the second group than in the control group (P < 0.05). TGF-β and SMAD2/3 gene expressions, as well as collagen protein expression, showed a significant increase in the third group compared to the second group (P < 0.05). Conclusions: Conocarpus leaf extract reduces the harmful effects of UVB radiation on HSF-PI 17 skin fibroblast cells.
