    Ecosystem services valuation using InVEST modeling: case from southern Iranian mangrove forests
    (Elsevier, 2023) Dashtbozorgi, Fatemeh; Hedayatiaghmashhadi, Amir; Dashtbozorgi, Ameneh; Ruiz-Agudelo, Cesar Augusto; Furst, Christine; Cirella, Giuseppe T.; Department of Physics; Naderi, Mortaza; Researcher; Department of Physics; College of Sciences; N/A
    As one of the most fertile ecosystems on earth, mangrove forests provide many goods and services for humanity. Mangroves are located in the south of Iran on the coasts of Sistan and Baluchistan, Hormozgan and Bushehr provinces, which include two species of Harra (Avicennia marina) and Chandal (Rhizophora mucronata) The purpose of this study was to describe the condition of mangrove forests using the integrated valuation of ecosystem services and tradeoffs (InVEST) between 2010 and 2021 from the southern coasts of Iran. The INVEST model uses land use and land cover maps to estimate habitat quality. With the opinions of local experts, sources of threats, maximum impact distance, state of degradation, and sensitivity to threats were also estimated for each type of land use cover. Urban and rural areas' development, roads network, piers, oil and non-oil industries, agriculture, and aquaculture activities, were identified as sources that threaten mangroves' long-term viability. The output maps of the INVEST habitat quality model included degradability and habitat quality maps, which were classified into four categories: poor, low, medium, and high, to better understand quality changes. The results demonstrated that mangrove habitat quality has decreased considerably despite the increase in their area. The area of the target habitats has been increased by 586.45 ha while two first quality categories, including poor and low classes, increased. Based on a habitat quality assessment in 2010, two classes of poor, low habitat quality, were estimated to be around 0.72, and 8.42 ha, which changed to 3.04 ha, and 9.72 ha respectively in 2021. The output maps obtained in this study can help local managers and decision-makers to have an image of what happened to the quality of the target ecosystems and may help them to adopt more effective management strategies for the conservation of these ecosystems.

    Effect of human-induced activities on waterbirds diversity and abundance in three wetlands of international importance in Iran
    (Maik Nauka/Interperiodica/Springer, 2019) Golzar, E.; Esfandabad, B. Shams; Morshedi, J.; Jozi, S. A.; Department of Physics; Naderi, Mortaza; Researcher; Department of Physics; College of Sciences; N/A
    Over six years from 2011 to 2015, direct field observations and waterbirds' surveys were performed in three Ramsar sites (Choghakhor, Shadegan and Parishan). Our results indicated that all three wetlands affected by developing intensive farming systems and lowered species richness. The most important difference existing among the wetlands points to the habitat of the specialist waterbirds, while we found no significant differences in the habitat of the generalist birds. Meanwhile, some completely dependent birds like White-headed Duck (Oxyura leucocephala) have completely disappeared. Our results indicated that 87 percent of the variation in the species richness and abundance can be justified by a combination of water depth, water area, sludge depth, conductivity, total phosphorus, newly developed farming areas and vegetation cover.

    Hares, humans, and lynx activity rhythms: who avoids whom?
    (Associazione Teriologica Italiana, 2021) Kuşak, J.; Bojarska, K.; Chynoweth, M.; Green, A.; Department of Molecular Biology and Genetics; Şekercioğlu, Çağan Hakkı; Naderi, Mortaza; Faculty Member; Researcher; Department of Molecular Biology and Genetics; College of Sciences; 327589; N/A
    Predator-prey interactions and human presence are among the key factors shaping large mammal activity patterns. In human-dominated landscapes, large carnivores must balance their activity rhythms between optimizing feeding opportunities and avoiding encounters with humans. In northeastern Turkey, the Caucasian lynx (Lynx lynx dinniki), a threatened subspecies of the Eurasian lynx (Lynx lynx), occupies habitats that are heavily fragmented and dominated by human presence in the warm part of the year. Using camera traps and GPS-collar activity sensors, we investigated lynx circadian activity patterns across lunar phases and seasons. We compared the activity pattern of the lynx to the activity pattern of its primary prey, the European hare (Lepus europaeus), and humans. We found that during the warm season (May-October), lynx displayed a bimodal crepuscular activity pattern typical for this species and consistent with hare activity. During the cold season (November-April), both lynx and hares shifted to predominantly diurnal activity. During the full moon, hares reduced their activity due to the anti-predator behaviour, followed by a corresponding adjustment in lynx activity patterns. We conclude that lynx activity in our study area is an outcome of weather conditions, human presence and foraging behaviour. Our results also corroborate the suitability of camera trapping data in documenting multiple species' temporal activity patterns.
