The late Miocene Baynunah Formation in western Abu Dhabi Emirate (United Arab Emirates) has yielded new bird fossils, including both skeletal and eggshell remains that we describe here, together with a revision and summary of previous findings. A ratite pelvis is characterized by its larger size compared with extant ostriches and is assigned to Struthio cf. karatheodoris. Fossil eggshells belong to the ootaxon Diamantornis laini as well as to an aepyornithoid type. Diamantornis laini is previously recorded from contemporaneous sites in Africa, and aepyornithoid eggshells are widespread across Neogene sites in Eurasia and Africa. Neognath birds are represented by three taxa, a cormorant Phalacrocorax sp. (size of P. fuscicollis), a darter Anhinga cf. hadarensis, and a heron of the tribe Nycticoracini. The darter attests to a link with Africa, being tentatively referred to a fossil species known from East Africa. The Baynunah birds provide valuable information on the biogeographic origins of different components of the avifauna in the late Miocene, near the junction between the Palaearctic, Indomalayan and Afrotropical zoogeographical regions.

I describe new specimens of carnivoran mammals from the continental late Miocene Baynunah Formation, exposed in the western coastal region of Abu Dhabi Emirate. New material collected between 2002 and 2014 includes dental specimens of the mustelid Plesiogulo sp. and a large-sized hyaenid, postcranial remains and an upper canine of a large- sized machairodontine felid, postcrania and a tooth of a medium-sized felid, and postcrania of a medium-sized mustelid. The latter two are new taxonomic records for the Baynunah Formation. With a minimum of six species, the carnivoran assemblage from the Baynunah Formation is the richest known from the Miocene of the Arabian Peninsula.

Reintroduction of once existing red mangrove, Rhizophora mucronata trials were carried out in Abu Dhabi, United Arab Emirates. Propagules were procured from Pakistan and cultured in a greenhouse before they were planted alongside existing Avicennia marina forest in two sites of Abu Dhabi emirate, Abu Al Abyad and Ras Ghanada Islands. This study documents the present condition of the plants after 11 years of plantation. Long term survival rate was as high as 81% in Abu Al Abyad while Ras Ghanada experienced a very low survival rate at 10%, primarily due to external factors. In contrast, Ras Ghanada plants showed higher growth with the mean height stands at 2.06 m (SD ± 0.31m), while in Abu Al Abyad it is 1.53 m (SD ± 0.36 m). In Abu Al Abyad, more than one third (36.4%) of surviving plants showed reproductive phenology, whereas in Ras Ghanada it was only 10.3%, despite of greater height classes. Many Rhizophora were also noticed with well-developed stilt roots. This study showed that Rhizophora mucronata can be planted in Abu Dhabi, despite the Emirate's harsh climatic conditions.

SummaryUnited Arab Emirates is an important range country for the ‘Vulnerable’ Socotra Cormorant Phalacrocorax nigrogularis and Abu Dhabi Emirate holds most of the remaining breeding colonies. Emirate-wide monitoring of all breeding colonies was undertaken annually for 11 breeding seasons from 2006–2007 to 2016–2017 to monitor the status of breeding colonies and estimate the nesting population. Breeding was recorded in 10 colonies that were used intermittently with an average of four (± 1.3 SD) colonies active each year. The highest number of eight active colonies was recorded in 2016–2017. Establishment of two new breeding colonies on Butinah and Digala in 2016–2017 and recolonisation of three previously inactive colonies during the monitoring period emphasised the ability of the species to relocate and colonise suitable sites. Continued threats at some breeding colonies caused abandonment and subsequent relocation, resulting in a gradual shift of breeding colonies to safer areas. Presently, most of the breeding sites (62%) with an increased number of breeding birds are found in colonies with restricted access. The Emirate-wide nesting population witnessed a 10-fold increase in the last decade; after an initial decline in 2006–2007 it increased from about 5,000 pairs in 2007–2008 to nearly 52,000 nesting pairs in 2016–2017. Combined with the nesting population from the Siniya colony, the overall UAE nesting population is estimated at 60,000 to 70,000 pairs, nearly half of the global breeding population. Further augmentation of the current breeding numbers is possible if breeding colonies remain safe from human disturbance and invasive predators. For long-term conservation of Socotra Cormorant, protection of all remaining colony sites, including inactive ones, is important in addition to minimising disturbance along with widespread public awareness to change the people’s perception of the species as a competitor to commercial fisheries.

This paper examines the effect of a number of individual attributes and characteristics on respondents’ intentions to support local cultural entrepreneurship ventures in the Abu Dhabi Emirate of the United Arab Emirates (UAE). The objective of the discussion is to capture the effect of a number of individual variables (such as age, gender, and place of residence) as well as tourism phenomena (repeat visit, time of visit) on the importance tourists in Abu Dhabi place on culture and cultural resources. Using binomial probability models, we measure how changes in age, income levels, length of stay, and other variables trigger changes in cultural appreciation among visitors in Abu Dhabi. This approach is based upon a natural extension of the bivariate descriptive analysis usually undertaken in the literature (Zaidi, 2001).
