“…For example, the metamorphosis was completed in 73 days for Rana pseudodalmatina in Golestan Province, Iran (Pesarakloo et al 2015), and 43-90 days for P. ridibundus in Anzali Lagoon, Iran (Mirzajani et al 2006), but 80-120 days for another population of the latter species in France (Momeni & Zamatkesh 2005). In contrast, P. bedriagae had LIFE-HISTORY TRAITS AND DEMOGRAPHY HYLA SAVIGNYI IN IRAN finished their development and commenced metamorphosis after 111 days (Pesarakloo & Najibzadeh 2019).…”

The life-history of an organism consists of its lifetime pattern of growth, development, storage, age, and reproduction. In this study, some life-history traits of Hyla savignyi were studied in populations from different parts of Iran. The microscopic and macroscopic analysis showed that testicular activity in H. savignyi is potentially continuous, reaching its peak level in April. Metamorphosis was completed in approximately 102 days after egg deposition, and body size at metamorphosis was 10 mm. Significant sexual size dimorphism was present in all populations, and a larger female asymptotic body size was observed (43.07 mm for females vs 41.16 mm for males). The adult survival rate (S) and life expectancy (ESP) were the same for both sexes (S = 0.73 and ESP = 4.2 years). Age and body size were positively correlated with each other for both females and males. Maximum longevity was recorded to be six years in both females and males, and ages of sexual maturity were estimated to be two or three years in breeding individuals. The adult sample age ranged from two to six years (mean age of females: 4.40±0.68 years; males: 3.63±0.13 years). Our data confirm the general patterns of body size variation and mean age in anurans and show that females are larger than males and live longer.

“…To test the efficiency of AAV serotype transduction across distantly-related frogs, we screened AAVs in wild-caught Levant water frogs, Pelophylax bedriagae , via intracerebroventricular injections at developmental larval stages 24-27 75,76 . After AAV5 and AAV-PHP.eB injection, we observed sparse but clear GFP expression in the telencephalon, with brightly marked neuronal soma and dendrites ( Figure 1R,S,U ).…”

Adeno-Associated Viral Tools to Trace Neural Development and Connectivity Across Amphibians

The development, evolution, and function of the vertebrate central nervous system (CNS) can be best studied using diverse model organisms. Amphibians, with their unique phylogenetic position at the transition between aquatic and terrestrial lifestyles, are valuable for understanding the origin and evolution of the tetrapod brain and spinal cord. Their metamorphic developmental transitions and unique regenerative abilities also facilitate the discovery of mechanisms for neural circuit remodeling and replacement. The genetic toolkit for amphibians, however, remains limited, with only a few species having sequenced genomes and a small number of transgenic lines available. In mammals, recombinant adeno-associated viral vectors (AAVs) have become a powerful alternative to genome modification for visualizing and perturbing the nervous system. AAVs are DNA viruses that enable neuronal transduction in both developing and adult animals with low toxicity and spatial, temporal, and cell-type specificity. However, AAVs have never been shown to transduce amphibian cells efficiently. To bridge this gap, we established a simple, scalable, and robust strategy to screen AAV serotypes in three distantly-related amphibian species: the frogsXenopus laevisandPelophylax bedriagae, and the salamanderPleurodeles waltl, in both developing larval tadpoles and post-metamorphic animals. For each species, we successfully identified at least two AAV serotypes capable of infecting the CNS; however, no pan-amphibian serotype was identified, indicating rapid evolution of AAV tropism. In addition, we developed an AAV-based strategy that targets isochronic cohorts of developing neurons - a critical tool for parsing neural circuit assembly. Finally, to enable visualization and manipulation of neural circuits, we identified AAV variants for retrograde tracing of neuronal projections in adult animals. Our findings expand the toolkit for amphibians to include AAVs, establish a generalizable workflow for AAV screening in non-canonical research organisms, generate testable hypotheses for the evolution of AAV tropism, and lay the foundation for modern cross-species comparisons of vertebrate CNS development, function, and evolution.

“…Pelophylax bedriagae (Camerano, 1882), the Levent Water Frog, was described from Dimashq in the current Syrian Arab Republic [34] (Figure 12). This species is known from Egypt, Israel, Türkiye, some Greek Islands, Cyprus, western Syria, Lebanon, Jordan, and western and southwestern Iran [130][131][132][133][134][135][136][137][138][139][140].…”

“…Pelophylax bedriagae is a largely aquatic species that is present in permanent wetlands with rich aquatic vegetation, and it relies on permanent ponds for breeding [135,141]. The breeding period starts in April and lasts until July [138]. Pelophylax bedriagae completes metamorphosis after 111 days in Iran [138] and mainly consumes insects [142].…”

Understanding species from an ecological and phylogenetic perspective facilitates an understanding of their conservation status in relation to the changing world. The frog genus Pelophylax is among the largest in terms of amphibian biomass in the Palearctic, but species have not been thoroughly studied at the Asian continental scale. The phylogeographic relationship, behavioural ecology, and ecological requirements within the genus need clarification, despite generally good local coverage. Here, for the first time, we conducted a literature review focused on phylogeography and behavioural ecology, supported by ecological niche modelling of twelve Asian Pelophylax lineages. Finally, we compiled the known threats for each of the lineages. We first determined the presence of twelve species and species-candidate lineages. In terms of behavioural ecology, the main difference among lineages is the time to metamorphosis and the time to reach sexual maturity. The ecological models highlighted a match between the known presence of each clade and their suitable habitat and highlighted the Syr Darya drainage on the eastern shore of the Caspian Sea for the non-described Pelophylax “Syr Darya lineage”. Finally, we highlighted the greatest variation among lineages in terms of threats, as some lineages are threatened by numerous factors, whereas others are expanding.
