Climatic conditions changing over time and space shape the evolution of organisms at multiple levels, including temperate lizards in family Lacertidae. Here we reconstruct a dated phylogenetic tree 262 lacertid species based on supermatrix relying novel phylogenomic datasets fossil calibrations. Diversification lacertids was accompanied by an increasing disparity among occupied bioclimatic niches, especially last 10 Ma, during period progressive global cooling. Temperate also underwent...

Based on morphological characteristics, two subspecies of the Transcaucasian rat snake (Zamenis hohenackeri) are currently recognized, namely Z. h. tauricus and hohenackeri. Both repeatedly considered to be conspecific colour morphs, or have even been confused with situla. Although, few studies involved in a phylogenetic approach, none has so far led any taxonomic changes. We assessed intraspecific variation phylogeographic relationships among specimens from different locations across its...

Snake venom variations are a crucial factor to understand the consequences of snakebite envenoming worldwide, and therefore it is important know about toxin composition alterations between taxa. Palearctic vipers genera Vipera, Montivipera, Macrovipera, Daboia have high medical impacts across Old World. One hotspot for their occurrence diversity Türkiye, located on border continents, but many venoms remain still understudied. Here, we present compositions seven Turkish viper By complementary...

Ornamental fish culture is considered as one of the most important source home entertainment, because its diversity and beauty picturesque colors. Trichodiniasis fishes causing harm economic losses in this industry. There are many records trichodinids ectoparasites infesting have been found throughout World, but no such attempt has made to study parasitic group ornamental fish, preferably oranda goldfish (Carassius auratus L.)

The rise of high-throughput sequencing techniques provides the unprecedented opportunity to analyse controversial phylogenetic relationships in great depth, but also introduces a risk being misinterpreted by high node support values influenced unevenly distributed missing data or unrealistic model assumptions. Here, we use three largely independent phylogenomic sets reconstruct phylogeny true salamanders genus Salamandra, group amphibians providing an intriguing study evolution aposematism...

The colonization patterns of oceanic islands are often interpreted through transmarine dispersal. However, in with intense human activities and unclear geological history, this inference may be inappropriate. Cyprus is such an island, whose geotectonic evolution has not been clarified yet to the desired level for biogeographical reconstructions, leaving questions 'how Cypriote biota arrived' 'does dispersal have formative role its diversification' unanswered. Here, we address these issues a...

Abstract Aim We assessed genetic relationships among populations for each of the four snake species found on C rete ( Z amenis situla , H ierophis gemonensis T elescopus fallax and N atrix tessellata ), including conspecific from A egean area. Our aim was to reconstruct their phylogeographical histories, especially regarding occurrence rete. Location Crete, S ea eastern M editerranean.

Herein, we report on the venom proteome of Vipera anatolica senliki, a recently discovered and hitherto unexplored subspecies critically endangered Anatolian meadow viper endemic to Antalya Province Turkey. Integrative venomics, including gland transcriptomics as well complementary bottom-up top-down proteomics analyses, were applied fully characterize V. a. senliki. Furthermore, classical venomics approach was extended elucidate by an alternative in-source decay (ISD) workflow using...

The venomous Levantine viper, Macrovipera lebetina is endemic to Cyprus. objective of this study was investigate in vitro cytotoxicity, vivo lethality, and antivenom production followed by a re-immunization schedule mice against venom. LD50 value estimated as 7.58 mg/kg within 24 hours different venom doses administrated intraperitoneally mice. Freund's complete incomplete adjuvants were used for first second immunization production. A cell-based assay performed determine the effects...

Body size is an ecologically important variable in animals. The geographical variation of most snakes and some lizards counters Bergmann's rule that, among related taxa, the larger ones live at warmer latitudes. However, exceptions notwithstanding, despite being ectothermic, turtles as a group tend to obey rule. We examined this idea Testudo graeca, ranging from Morocco Romania Iran with disputed systematics, both global scale (using literature) within focal area Israel museum specimens)....

The colubrid snakes of the genus Rhynchocalamus are seldom studied and knowledge their ecology life history is scarce. Three species currently recognized, R. satunini (from Turkey eastwards to Iran), arabicus (Yemen Oman), melanocephalus Sinai Peninsula northwards Turkey).

The genus Rhynchocalamus comprises three species distributed in Southwest Asia. Little is known about them, most probably because of their secretive fossorial lifestyle. poor knowledge the even underscored by fact that its phylogenetic affinities remained unclear until very recently. least species, arabicus, only from holotype collected Aden, Yemen, and it has not been observed since description 1933. Here we provide a second record for this which represents first Oman. This extends range...
