“…Waterbird composition differs between seasons as expected. A similar result has been found in other wetlands (Ghasemi et al 2012;Donatelli et al 2014;Souza et al 2014).…”
Artificial wetlands can play an important role in waterbird conservation due to habitat loss and degradation of natural wetlands. Urban reservoirs can harbor waterbird communities, but they usually have lower biological diversity than natural wetlands. However, the value of reservoirs for waterbird conservation in urban areas needs further exploration. Here, we surveyed the waterbird community in a water-level controlled reservoir of an urban area in southeastern Brazil. We evaluate the seasonal variation in species composition, richness, and abundance. Monthly samplings were carried out between July 2017 and February 2018, through a boat line transect. A total of 7762 waterbirds were recorded, belonging to 32 species and 16 families. There were significant differences in species composition and abundance between dry and rainy seasons. The community was dominated by generalist and resident species, which Gallinula galeata and Jacana jacana were the most abundant species. We did not register migratory shorebirds during the surveys. Our results highlight the importance of reservoirs in urban areas, as they harbor feeding areas and breeding sites and may serve as refuges during dry seasons for resident waterbirds. We suggest management strategies to improve the importance of waterlevel controlled reservoirs as breeding areas for resident species and migratory stopover for shorebirds. Our results may also be considered for urban planning and waterbird conservation in urban areas.

“…In fact, the species-richness recorded at Fuwairit compares favorably to other mangrove bird studies where longer term surveys took place [17]. In adjacent Iran, Gashemi et al [19] recorded the seasonal variation in the avifauna in a much larger deltaic mangrove forest-wetland system and observed 56 waterbird species. Given that in our case study we observed 28 species solely in the mangrove habitat in just 5 days (with an average of 15 species per day), it seems likely that with further study the total species richness at Fuwairit may probably reach the scale of the Iranian study.…”

“…Although tropical mangroves are known for their biological productivity [17], very little ornithological research has been done on subtropical mono-species mangrove patches such as these in Qatar [see 8,19,20,21 and references therein]. Mangrove habitat may be of significant value for biodiversity along a desert coastline such as on the Arabian/Persian Gulf, where any woodland-like structure is extremely scarce.…”
In the western part of the Arabian/Persian Gulf, coastal habitats such as intertidal wetlands and mangroves are scarce and poorly studied. We conducted a rapid assessment survey of bird species richness and abundance at the Fuwairit khor lagoon in northern Qatar, using a line transect count scheme to collect data from six different generic habitat types, repeated during five consecutive days in late April 2013. To further analyze the ecological requirements of the surveyed bird assemblage per habitat type, we assigned ecological guild categories to each species and distinguished among migrants, local, and regional breeders. Mangrove and intertidal mudflats hosted the highest bird densities and the most distinctive assemblages, while the beach habitat had high concentrations of birds but relatively few species. In contrast to the wetland habitats, near-shore marine areas and dune habitats had very limited numbers of birds and a relatively depauperate species assemblage. Employing a habitat perspective in a quantitative bird survey method shows that birds are effective biodiversity indicators for a rapid survey of coastal features in a poorly-studied region of the Arabian/Persian Gulf.Titre : Utilisation des habitats côtiers par l'avifaune au Qatar: Aperçus d'une brève évaluation durant la migration printanière Les habitats côtiers, tels que les lagons, les zones intertidales associées et les mangroves, sont particulièrement rares et peu étudiées dans la partie occidentale de l'Arabie/Golfe Persique. Pour la planification de la conservation en milieu côtier, il est crucial d'effectuer un suivi de la biodiversité, et l'avifaune peut constituer un bon bio-indicateur pour la définition des mesures de conservation prioritaires. Dans le présent cas d'étude, des échantillonnages printaniers des populations d'oiseaux et de leur richesse spécifique par type d'habitat ont été entrepris dans la zone côtière du lagon de Fuwairit dans le nord du Qatar. Pour cela, des comptages par transect linéaire ont été répétés durant cinq jours consécutifs fin avril 2013. Afin d'analyser plus en détail les exigences écologiques locales de l'avifaune, les espèces d'oiseaux ont été regroupées par guilde écologique, et une distinction a été faite entre les espèces migrantes, celles se reproduisant localement et celles se reproduisant dans la région. Les mangroves et les baies ensablées se sont avérées être les milieux accueillant les plus grandes densités d'oiseaux et les assemblages les plus originaux, tandis que les plages présentaient une forte densité mais une faible diversité d'espèces. Contrairement aux milieux aquatiques situés plus dans les terres, les habitats marins côtiers et les dunes accueillaient un nombre très limité d'oiseaux et un assemblage d'espèces relativement pauvre. L'utilisation d'une classification des habitats dans le cadre d'un suivi quantitatif des populations d'oiseaux a permis de montré que l'avifaune pouvait constituer un indicateur efficace dans le but de réaliser une évaluation rapide des caractéristi...
“…Salinity fluctuates between 38 to 50 g/L in the mangrove forest (Zahed et al 2010). Hara Biosphere Reserve is among the richest ecosystems in the Persian Gulf and hailed in the Middle East for its "megadiversity" (Ghasemi et al 2012).…”
Despite the importance of biosphere reserves in Iran's livelihood and welfare, the economic significance of Hara Biosphere Reserve has never been comprehensively studied. This study examines the current importance of Hara Biosphere Reserve (HBR) in local livelihood and welfare. Using a household survey, data were collected through a questionnaire, key informant interviews and direct observations. Two hundred and fortyfour households were randomly selected from 10 villages through proportional sampling. Results showed that non-environmental income was the first driver of the total income, poverty alleviation and narrowing income inequality gap. Park income was the second. The results also showed that excluding park income from total income would significantly increase headcount poverty, widen the poverty gap, and raise the Gini coefficient. Wealthier households had the greatest absolute income from the environment, including forest, fishing and fodder. However, the poorest group had smallest absolute income from these sources. Thus, the study demonstrated that wealthier households are responsible for the overharvesting of environmental resources. Interestingly, the study showed that wealthier households are more dependent on profitable environmental incomes sources while the poorest are more dependent on nonprofitable ones.
