“…The migration and dispersion of non-indigenous species in the Mediterranean is, in fact, a phenomenon related to climate change in relation to the biology and ecology of the species in question. The amount of time since their introduction into a new habitat and prevailing climatic conditions is decisive for the dispersion of a species, while the type of egg determines the main route of propagation in the Mediterranean [40,71]. The data show that there are more species with pelagic eggs.…”

“…The temperature of the Mediterranean waters has increased by 0.041 ± 0.006 • C/year from 1982 to 2018 [31]. Studies on biodiversity in the Mediterranean highlight an increase in the number of non-indigenous species [32][33][34][35][36][37][38][39] and report on methods to accurately detect their presence [40,41]. Tropicalization and southernization phenomena are also evidenced by DNA barcoding analysis [40][41][42].…”

Tropicalization and southernization phenomena are also evidenced by DNA barcoding analysis [40][41][42]. At present, many climate studies focus on forecasting models based on emission scenarios and on bioinvasions, and seek an answer to objective 13 of Agenda 2030 integrating diverse methodologies [43][44][45][46].…”

This paper characterizes non-indigenous fish species (NIS) and analyses both atmospheric and sea surface temperatures for the Mediterranean coast of Egypt from 1991 to 2020, in relation to previous reports in the same areas. Taxonomical characterization depicts 47 NIS from the Suez Canal (Lessepsian/alien) and 5 from the Atlantic provenance. GenBank accession number of the NIS mitochondrial gene, cytochrome oxidase 1, reproductive and commercial biodata, and a schematic Inkscape drawing for the most harmful Lessepsian species were reported. For sea surface temperatures (SST), an increase of 1.2 °C to 1.6 °C was observed using GIS software. The lack of linear correlation between annual air temperature and annual SST at the same detection points (Pearson r) could suggest a difference in submarine currents, whereas the Pettitt homogeneity test highlights a temperature breakpoint in 2005–2006 that may have favoured the settlement of non-indigenous fauna in the coastal sites of Damiette, El Arish, El Hammam, Alexandria, El Alamain, and Mersa Matruh, while there seems to be a breakpoint present in 2001 for El Sallum. This assessment of climate trends is in good agreement with the previous sightings of non-native fish species. New insights into the assessment of Egyptian coastal climate change are discussed.

“…Environmental programs in the last decades highlight the importance of organisms for monitoring climate changes and pollutants (Mani and Kumar 2014;De Maio et al 2014;Dixit et al 2015;Guerriero et al 2018a,b;Gentilucci et al 2020). Aquatic animals such as amphibians can accumulate heavy metals from the environment directly by absorption through skin and oral surfaces and indirectly by ingestion of heavy metals contaminated food items.…”

Our study attempted to monitor the quality of water in Medjarda basin (Northeastern Algeria) and to provide baseline information of heavy metals in the water as well as in a potential amphibian biosentinel, the spiny toad, Bufo spinosus. We measured pH, temperature, dissolved oxygen and biological oxygen demand of water and levels of heavy metals in toad skin using an atomic absorption flame spectrophotometer. Lead (Pb) concentration in water and in toad skin at all sites exceeded respectively 60 and 96 times the standard reference values. The heavy metal concentrations, in descending order, in water and in male toad skin were as follows: Pb > Fe > Cu > Zn and Fe > Pb > Zn > Cu respectively. This study highlights the ecological status of the surrounding areas upstream of the Medjarda basin as being a point source of heavy metal pollution. It is further stated that a non-invasive skin removal is an ethically sound technique to evaluate heavy metal accumulation in aquatic animals like toad, without euthanizing the specimens and making any loss to biodiversity of the species.

“…However, factors such as data weight and type tend to affect them, and this could result in a violation of the normality of these models (Figure 3). This however resulted in the predilection of non-parametric methods (such as the Mann-Kendall, Hotelling-Pabst, and Sen tests amongst others) over their parametric counterparts especially given their significance in trend detection (Gocic and Trajkovic, 2013;Gentilucci et al, 2021) [94,95].…”

Assessing Freshwater Changes over Southern and Central Africa (2002–2017)

et al. 2021

In large freshwater river basins across the globe, the composite influences of large-scale climatic processes and human activities (e.g., deforestation) on hydrological processes have been studied. However, the knowledge of these processes in this era of the Anthropocene in the understudied hydrologically pristine South Central African (SCA) region is limited. This study employs satellite observations of evapotranspiration (ET), precipitation and freshwater between 2002 and 2017 to explore the hydrological patterns of this region, which play a crucial role in global climatology. Multivariate methods, including the rotated principal component analysis (rPCA) were used to assess the relationship of terrestrial water storage (TWS) in response to climatic units (precipitation and ET). The use of the rPCA technique in assessing changes in TWS is warranted to provide more information on hydrological changes that are usually obscured by other dominant naturally-driven fluxes. Results show a low trend in vegetation transpiration due to deforestation around the Congo basin. Overall, the Congo (r2 = 76%) and Orange (r2 = 72%) River basins maintained an above-average consistency between precipitation and TWS throughout the study region and period. Consistent loss in freshwater is observed in the Zambezi (−9.9 ± 2.6 mm/year) and Okavango (−9.1 ± 2.5 mm/year) basins from 2002 to 2008. The Limpopo River basin is observed to have a 6% below average reduction in rainfall rates which contributed to its consistent loss in freshwater (−4.6 ± 3.2 mm/year) from 2006 to 2012.Using multi-linear regression and correlation analysis we show that ET contributes to the variability and distribution of TWS in the region. The relationship of ET with TWS (r = 0.5) and rainfall (r = 0.8) over SCA provides insight into the role of ET in regulating fluxes and the mechanisms that drive precipitation in the region. The moderate ET–TWS relationship also shows the effect of climate and anthropogenic influence in their interactions.
