“…The hotspot model has been used extensively to predict the location of the bird population (Chen, 2007;Jenkins et al, 2010). In additionally, extensive studies on species hotspots have been conducted worldwide, encompassing countries such as the Poland (Walesiak et al, 2022) and Namibian (Barnard et al, 1998), Chile (Lisón et al, 2022), Taiwan (Ko et al, 2014), Brazil (Iezzi et al, 2018), China (Hu et al, 2017), California (Yen et al, 2006), Spanish (Arcos et al, 2012). Unfortunately, the hotspots of wetland birds in Marsh Dalmaj, southern Iraq, are still unknown.…”

The escalating human population, urbanization, anthropogenic activities, overhunting of wetland birds, and habitat fragmentation present persistent challenges to the delicate ecosystem. However, Marsh Dalmaj stands as a vital sanctuary for migrating birds, harboring remarkable biodiversity that underscores the need to prioritize the conservation of wetland avifauna. The study spanned from September 2020 to August 2022. Our methodology encompassed several techniques: (KDE) was employed to delineate suitable and non-suitable habitats, Hotspot Modeling determined the fidelity of suitable habitats, the LST and NDVI algorithms were utilized to monitor climate change, the point count protocol (PCP) enabled precise recording of wetland bird species, and the Adaptive Neuro-Fuzzy Inference System (ANFIS) was employed to predict future scenarios over a span of 50 years. In 2021, the average LST in suitable habitats was 42.37°C, accompanied by an NDVI value of 0.33. In contrast, non-suitable habitats exhibited an average LST of 45.5°C and an NDVI of -0.13. Additionally, the Area of Occupancy (AOO) encompassed 50.83 km² of suitable habitat and 93.21 km² of non-suitable habitat, while the Extent of Occurrence (EOO) covered 144.04 km². These findings suggest that the EOO and AOO of wetland birds are nearing endangered status according to the criteria set by the (IUCN). Furthermore, the analysis identified 14 hotspots within the AOO, with confidence levels ranging from 90–99%, signifying areas of significant ecological importance. We conclude from our study that highlights the key pathways of a 50-year scenario, demonstrating the negative impact of continuous climate change, specifically LST, on marsh bird populations and NDVI. Consequently, it is crucial for the Iraq Environmental Ministry (IEM) to play an active and influential role in shaping environmental policies and promoting sustainable management approaches, particularly in conserving the biodiversity of the Marsh Al-Dalmaj region

“…Identification and protection of biodiversity hotspots constitute one of the most important tools for conservation planning (Bellard et al, 2014;Midgley et al, 2002;Myers et al, 2000). For several decades, hotspots of richness, endemism, and rare species have been used in various environments as a tool to define the core zones and boundaries of protected areas networks (Barnard et al, 1998;Lascelles et al, 2012;Lombard, 1995), often while focusing selection on species occurrence and richness (Bonn and Gaston, 2005;Kati et al, 2004). The basic role of reserves is to separate elements of biodiversity from processes that threaten their existence in the wild (Margules and Pressey, 2000).…”

Farmland landscapes are recognized as important ecosystems, not only for their rich biodiversity but equally so for the human beings who live and work in these places. However, biodiversity varies among sites (spatial change) and among seasons (temporal change). In this work, we tested the hypothesis that bird diversity hotspots distribution for breeding is congruent with bird diversity hotspots for wintering season, focusing also the representation of protected areas for the conservation of local hotspots. We proposed a framework based on the use of species richness, functional diversity, and evolutionary distinctiveness to characterize avian communities. Although our findings show that the spatial distribution of local bird hotspots differed slightly between seasons, the protected areas’ representation was similar in both seasons. Protected areas covered 65% of the most important zones for breeding and 71% for the wintering season in the farmland studied. Functional diversity showed similar patterns as did bird species richness, but this measure can be most effective for highlighting differences on bird community composition. Evolutionary distinctiveness was less congruent with species richness and functional diversity, among seasons. Our findings suggest that inter-seasonal spatial congruence of local hotspots can be considered as suitable areas upon which to concentrate greater conservation efforts. However, even considering the relative congruence of avian diversity metrics at a local spatial scale, simultaneous analysis of protected areas while inter-seasonally considering hotspots, can provide a more complete representation of ecosystems for assessing the conservation status and designating priority areas.
