Torquigener flavimaculosus Hardy & Randall (1983) was described based on specimens collected from the Gulf of Aqaba, Gulf of Suez, and Gulf of Aden, which has then penetrated the Mediterranean Sea, becoming one of the most abundant invasive tetraodontids. A comparison of samples collected from the northern Levant coasts of Türkiye between 2007 and 2020 showed that morphometric and meristic characteristics do not fully match either with T. flavimaculosus, or the closely related congeneric species T. hypselogeneion and T. altipinnis. Multivariate analysis carried out by 16 morphometric and six meristic characters did not show any discrimination between the above-mentioned species and exhibited almost identical sequences in genetic analysis. The results strongly suggest that T. flavimaculosus and T. hypselogeneion are conspecific, making the former species a junior synonym of the latter.

Marine turtles have temperature-dependent sex determination and the increase in global temperature could cause female predominance due to higher nest temperatures. The temperatures of 163 Green Turtle nests were measured with temperature data loggers at Akyatan beach, Turkey. The mean entire incubation duration (EID) and the sexdetermination period (SPD) temperatures of the Green Turtle nests were 31.03°C and 30.81°C respectively. The mean incubation duration (ID) was 51.94 days. Significant differences were found in terms of ID among nesting seasons, and ID had a negative relationship with the nesting seasons. The mean ID for the nesting seasons had a statistically significant negative correlation with EID temperature. The mean female ratio estimation for the nesting seasons was 89%. Significant differences were found among the female ratio estimations for the nesting seasons. The mean female ratio estimation for the nesting seasons showed a statistically significant negative correlation with ID and nest depth. Long-term temperature increase may pose a threat to the Green Turtle populations.

The Egyptian Vulture Neophron percnopterus is globally endangered and its population shows a decreasing trend. Within Turkey, the largest breeding population is found in the Beypazarı region north of Ankara. In the breeding season of 2020, we identified 109 occupied nest sites and breeding activities were recorded in 90 of them (breeding propensity 82.6%). Seventy-one young fledged from 62 nests and 28 nests failed, which gives a breeding success of 0.69 successful pairs per active nest, a fledging success of 1.15 fledglings per active nest, and a productivity of 0.65 fledglings per occupied nest site. Electrocution and collision, poisoning, and habitat loss are the main threats to the species in Turkey. In our study area, the number of active nests increased from 69 in 2016 to 90 in 2020.

This paper provides an overview of the Neurigona species found in Iran. During our studies in northern Iran four species of the genus Neurigona Róndani, 1856 have been collected, three of which for the first time in Iran: Neurigona helva Negrobov & Tsurikov, 1990, Neurigona pallida (Fallén, 1823) and Neurigona pseudolongipes Negrobov, 1987. One species, Neurigona persiana Pollet & Kazerani sp. n., proved new to science and is described here.

A new gammarid Dursogammarus dromaderus gen. et sp. nov. (Amphipoda: Gammaridae) is described from coastal Black Sea habitats of the southwestern foothills of the Russian Caucasus, being an obligate dweller of coastal pebbles. The new species morphologically resembles representatives of Echinogammarus Stebbing, 1899 and Dikerogammarus Stebbing, 1899, and somewhat Gmelina G. O. Sars, 1894, but can be easily separated by a unique combination of morphological features not characteristic for the latter genera. The most remarkable features are the presence of a dorsal knob (tubercle) on urosomal segment I as well as the long and wide outer ramus (exopod) of uropod III with mostly reduced distal article. http://www.zoobank.org/urn:lsid:zoobank.org:pub:846A98BC-D67B-4F4A-9E08-C6FF6FE9017A
在俄罗斯高加索西南山麓黑海沿岸栖息地发现了一种新的伽马marus dromaderus gen. et sp. nov.(两栖目:伽马maridus gen. et sp. nov.)，它们是沿岸鹅卵石的专性居民。新种在形态上类似Echinogammarus Stebbing(1899)和Dikerogammarus Stebbing(1899)的代表种，以及Gmelina g.o. Sars(1894)的代表种，但可以很容易地通过一种独特的形态特征组合将后者所不具有的特征区分开来。最显著的特征是在尿体I节上存在一个背丘(结节)，以及尿足III的长而宽的外支(外足)，远端节大部分缩小。http://www.zoobank.org/urn:lsid:zoobank.org:pub:846A98BC-D67B-4F4A-9E08-C6FF6FE9017A

Ghost Crabs, Ocypode cursor (Linnaeus, 1758), are used as a bioindicator species to evaluate the ecological condition of sandy beaches. Studies using Ghost Crabs as bio-indicator have often focused on the influence of human disturbance and beach geomorphology, separately. However, the relative importance of these variables should be assessed to maintain community structure. Here, I used an indirect burrow examination technique to understand whether Ghost Crabs respond to human disturbance stronger than to geomorphological properties of the sites. I analysed sand compaction rate, sand grain size, beach width, and beach slope as geomorphological features and urbanization index as a measure of human disturbance on each site. I further examined Ghost Crab burrows by counting and measuring the openings. Ghost Crabs showed lower population density and individual body sizes as a response to human disturbance, and the level of this response was partly related to the geomorphological features of the sites. However, human disturbance explained approximately 72% of the variation in the Ghost Crab burrow density and about 70% of the variation in the burrow size, alone. The findings of this study corroborate the use of Ghost Crabs as an efficient bioindicator species of human disturbance on sandy shores to achieve efficient beach management, yet suggest that managers and scientists should combine the influences of geomorphological features of the beaches and the degree of human disturbances in their ecological assessments.

The Dorcas Gazelle, Gazella dorcas, has lost 86% of its global historical range, and is regionally categorized as endangered by the IUCN. The factors that caused this decline have never been quantified. In this work, field and remotely sensed data were used to examine the ecological and anthropogenic factors affecting the abundance of Dorcas Gazelle within Wadi El-Gemal Protected Area in the Eastern desert of Egypt, using Generalized Linear Mixed Models (GLMM). The species’ abundance is shaped by anthropogenic activities (number of car trails and proximity to the coastal road) more than ecological factors (vegetation and wetness indices). Dorcas Gazelle is avoiding more humid and greener areas because of human disturbance. Such suitable habitats may be perceived by gazelles as too dangerous, and the animals therefore prefer less suitable but safer habitats that are further away or less frequented by humans. Moreover, an easy to conduct, cheap monitoring tool, the Kilometric Abundance Index (KAI), was devised and implemented for baseline information to be used for future monitoring of Dorcas Gazelle.
