Annotation:

Despite being one of the smallest states in Mexico, the high diversity of habitats in Morelos has led to the development of a rich biota made up of a mixture of species typical of the Neovolcanic Axis and the Sierra Madre del Sur. However, recent expansion of cities in Morelos is likely to have consequences for the state’s herpetofauna. Here a checklist of the amphibians and reptiles of Morelos is provided with a summary of their conservation status and overlap with its neighboring states. Morelos is home to 139 species of amphibians and reptiles representing 32 families and 75 genera. Twenty-six of the 38 species of amphibians and 70 of the 101 species of reptiles that inhabit Morelos are endemic to Mexico. Fourteen species of amphibians and reptiles from Morelos are IUCN listed (i.e., Vulnerable, Near Threatened, or Endangered), 22 are placed in a protected category by SEMARNAT, and 41 are categorized as high risk by the EVS. The Tropical Deciduous Forest vegetation type hosts the greatest number of amphibian and reptile species in Morelos (84 species). Morelos shares the largest proportion of its herpetofauna with the State of Mexico (79.3%), Puebla (77.0%), and Guerrero (74.8%).

Annotation:

The hedgehog signaling pathway plays a vital role in human and animal patterning and cell proliferation during the developmental process. The hedgehog gene family of vertebrate species includes three genes, Shh, Dhh, and Ihh, which possess different functions and expression patterns. Despite the importance of hedgehog genes, genomic evidence of this gene family in reptiles is lacking. In this study, the available genomes of a number of representative reptile species were explored by utilizing adaptive evolutionary analysis methods to characterize the evolutionary patterns of the hedgehog gene family. Altogether, 33 sonic hedgehog (Shh), 25 desert hedgehog (Dhh), and 20 Indian hedgehog (Ihh) genes were obtained from reptiles, and six avian and five mammalian sequences were added to the analysis. The phylogenetic maximum likelihood (ML) tree of the Shh, Dhh, and Ihh genes revealed a similar topology, which is approximately consistent with the traditional taxonomic group. No shared positive selection site was identified by the PAML site model or the three methods in the Data Monkey Server. Branch model and Clade model C analyses revealed that the Dhh and Ihh genes experienced different evolutionary forces in reptiles and other vertebrates, while the Shh gene was not significantly different in terms of selection pressure. The different evolutionary rates of the Dhh and Ihh genes suggest that these genes may be potential contributors to the discrepant sperm and body development of different clades. The different adaptive evolutionary history of the Shh, Dhh, and Ihh genes among reptiles may be due to their different functions in regulating cellular events of development from the embryonic stages to adulthood. Overall, this study has provided meaningful information regarding the evolution of the hedgehog gene family in reptiles and a theoretical foundation for further analyses on the functional and molecular mechanisms that have shaped the reptilian hedgehog genes.

Annotation:

Amphibians and reptiles are experiencing serious declines, with the number of threatened species and extinctions growing rapidly as the modern biodiversity crisis unfolds. For amphibians, the panzootic of chytridiomycosis is a major driver. For reptiles, habitat loss and harvesting from the wild are key threats. Cryopreservation and other assisted reproductive technologies (ARTs) could play a role in slowing the loss of amphibian and reptile biodiversity and managing threatened populations through genome storage and the production of live animals from stored material. These vertebrate classes are at different stages of development in cryopreservation and other ARTs, and each class faces different technical challenges arising from the separate evolutionary end-points of their reproductive biology. For amphibians, the generation of live offspring from cryopreserved spermatozoa has been achieved, but the cryopreservation of oocytes and embryos remains elusive. With reptiles, spermatozoa have been cryopreserved in a few species, but no offspring from cryopreserved spermatozoa have been reported, and the generation of live young from AI has only occurred in a small number of species. Cryopreservation and ARTs are more developed and advanced for amphibians than reptiles. Future work on both groups needs to concentrate on achieving proof of concept examples that demonstrate the use of genome storage and ARTs in successfully recovering threatened species to increase awareness and support for this approach to conservation.

Annotation:

Reptiles are rarely included in urban freshwater biodiversity monitoring and conservation. We explored the global persistence of freshwater dependent turtles, lizards, crocodilians and snakes in cities with a population greater than 100,000 using species occurrence data in online databases from a five-year period (2013–2018). We then used ecological niche models to help identify the locations of suitable habitats for three freshwater reptile species in Sydney, Australia. Our Global analysis showed that sightings of a majority of known species of crocodilians and freshwater turtles were recorded in databases within this 5-year period in contrast to about one in three freshwater lizard species and one in ten freshwater snake species and that freshwater reptiles were observed within 50 km of the center of 40% of the 3525 cities. While global databases hold substantial recent species occurrence records for some regions, they contain very little data for large parts of the world. Modelling showed that potential suitable habitat for the three freshwater species in Sydney was distributed across areas with different levels of urban development. The persistence of populations of freshwater reptiles in and around a large proportion of the world’s cities show that this group can play an important role in urban biodiversity conservation.

Annotation:

The adaptive significance of temperature-dependent sex determination (TSD) has attracted a great deal of research, but the underlying mechanisms by which temperature determines the sex of a developing embryo remain poorly understood. Here, we manipulated the level of a thyroid hormone (TH), triiodothyronine (T 3 ), during embryonic development (by adding excess T 3 to the eggs of the red-eared slider turtle Trachemys scripta , a reptile with TSD), to test two competing hypotheses on the proximate basis for TSD: the developmental rate hypothesis versus the hormone hypothesis . Exogenous TH accelerated embryonic heart rate (and hence metabolic rate), developmental rate, and rates of early post-hatching growth. More importantly, hyperthyroid conditions depressed expression of Cyp19a1 (the gene encoding for aromatase) and levels of oestradiol, and induced more male offspring. This result is contrary to the direction of sex-ratio shift predicted by the developmental rate hypothesis , but consistent with that predicted by the hormone hypothesis . Our results suggest an important role for THs in regulating sex steroid hormones, and therefore, in affecting gonadal sex differentiation in TSD reptiles. Our study has implications for the conservation of TSD reptiles in the context of global change because environmental contaminants may disrupt the activity of THs, and thereby affect offspring sex in TSD reptiles.

Der volle Inhalt der Quelle

Annotation:

All native reptile species are protected against harm through their inclusion on UK legislation. With the exception of two species, this protection does not extend to reptile habitat. As a result, reptiles are frequently subject to mitigation translocations to facilitate the development of land. However, there are few published studies of the effects of mitigation translocation on reptile populations and whether such translocations are effective conservation interventions. The effectiveness of translocation was tested through a combination of: 1) field surveys of sites subject to mitigation across England and Wales; 2) the radio tracking of translocated adders; 3) the monitoring of a population of slow-worms at site where they were released 20 years ago; and 4) a penning experiment to test whether viviparous lizards attempt to disperse from the release site. Very few translocated reptiles were encountered during the monitoring of release sites. This paucity of recaptures is either due to post-release mortality, imperfect detection or dispersal. Translocated male adders dispersed farther and had larger home range sizes than resident conspecifics. Some male adders undertook large unidirectional migrations back to the donor site crossing areas of unsuitable habitat as they did so. A population of slow-worms persisted at an isolated site two decades after translocation, albeit in relatively small numbers. Body condition improved over 20 years and the population resumed breeding and recruitment. The temporary penning of viviparous lizards was effective in preventing post-release dispersal and resulted in an increase in recapture rates of greater than 16 times when compared to unpenned viviparous lizard populations. The fact that no lizards were recaptured in the unpenned areas provides strong evidence for the effect of post-release dispersal. Although, mitigation translocations may prevent the immediate death of animals that would otherwise be destroyed with their habitat, there is little evidence that they are compensating for the loss of populations on a broad scale.

Tabelas de estágio embrionário podem ser utilizadas para detectar semelhanças e diferenças de caracteres entre grupos e como ferramenta para estudos baseados na fase embrionária. Neste estudo, ovos do lagarto Iguana iguana foram utilizados para a elaboração de uma tabela de estágios e para determinar o padrão de excreção durante o desenvolvimento. Iguana é um modelo conveniente por produzir numerosas desovas de ovos de tamanho grandes, propiciando um fácil manuseio e um bom número de réplicas. Após a oviposição, 18 estágios embrionários foram determinados durante os quais uréia foi o resíduo nitrogenado principal. Apesar do iguana ser o primeiro lagarto estudado, o padrão ureotélico é comum entre a maioria das espécies reptilianas estudadas até o momento. A casca pergaminácea permite que os ovos dobrem em massa devido à absorção de água, e o mecanismo pelo qual os embriões lidam com a diluição e osmolaridade resultante é um tema interessante para futuros trabalhos e comparações com espécies de cascas rígidas. Há evidência de desenvolvimento heterocrônico dos membros e o desenvolvimento de iguana é similar ao do lagarto Anolis sagrei, também do clado Iguania. Mais estudos de desenvolvimento de lagartos são necessários e a utilização de critérios morfológicos similares para facilitar a comparação de eventos embrionários.
A Table of embryonic stages can be used to detect similarities and differences in developmental features between groups and as a tool for studies based on embryonic phase. In this study, eggs of the lizard Iguana iguana were used to elaborate a staging table and to determine the nitrogen excretion pattern during the development. Iguana is a convenient model for having a large clutch of large eggs, allowing an easy handling and a good number of replicates. After oviposition embryonic stages were determined during which urea was the main nitrogen waste. Although iguana is the first lizard studied, the ureotelic pattern is common among the majority of reptilian species so far studied The pergaminaceous shell allows that the eggs double in mass due to water absorption, and the mechanism and how the egg deals with dilution and resultant osmolarity is an interesting issue for future works and comparisons with species of rigid eggshells. There is evidence of heterocronic development of the limbs and the development of iguana is similar to the lizard Anolis sagrei, also from the clade Iguania. Further studies on lizard evelopment are required and the use of similar morphological approach to facilitate comparisons of embryonic events

Annotation:

The major histocompatibility complex region (MHC) is a multi gene family present in all jawed vertebrates, with a fundamental role in vertebrate immunity. More than two decades of studies have resulted in the characterization of over a dozen MHC regions, and models of evolution explaining that the MHC has gradually increased in size and gene content since its origins without addressing their genomic context or the environmental selective forces. Furthermore, a compelling reconstruction of the evolutionary history of the MHC has been hampered due to phylogenetic gaps and the absence of comparative phylogenetic methods applied to comparative genomics. Here I reconstruct 320 MY of MHC evolution using 42 amniote genomes using improved gene annotations, genomic alignments and phylogenetic algorithms to reconstruct the evolution of the MHC at three levels of phylogenetic resolution. The first one describes 25 MY of evolution of the primate MHC using eight Human and four non-Human primate MHC haplotypes. Results suggests that highly dense gene segments have a strikingly conserved gene organization, and six conserved and highly rearranging segments overlap genes that are most commonly associated to disease. Phylogenomic analysis implies that the MHC has remained stable in gene content and size, with significantly increased duplication rates in the primate ancestors. The second one describes 280 MY of MHC evolution through the first characterization of reptilian MHC region, which combines mammalian, reptilian, Bird and amphibian characteristics, which favors the hypothesis of the existence of a primordial MHC in which natural killer receptors, CD1 and lectin genes co-exist. The Anolis MHC expands our understanding of the origins of the exceptionally small Bird MHC regions and provides further information about the organization and size of the ancestral amniote MHC. The third one compares 42 amniote MHC regions and map gene duplications and losses to further evaluate the mode and tempo of the evolution of the region. Comparative phylogenetic methods imply that the genomic and environmental factors affect the diversification of MHC during 320 My of evolution.

Este estudo compreende a descrição do desenvolvimento do crânio cartilaginoso e dérmico das seguintes espécies de lagatos iguanídeos: Anisolepis grilli (Leiosauridae), Hoplocercus spinosus (Hoplocercidae), Iguana iguana e Tropidurus sp. (Tropiduridae) e Tupinambis merianae (Teiidae), um representatnte de Scleroglossa. A descrição do desenvolvimento do crânio destes taxons é inédita. O objetivo deste trabalho é descrever e comparar os padrões de desenvolvimento dos lagartos que compõe o clado Iguania com os padrões já descritos para outros grupos de Squamata. Através do processo de diafanização foram estudadas séries embriológicas das espécies supracitadas. As descrições foram complementadas com a descrição do desenvolvimento craniano de Polychrus acutirostris (Polychrotidae) (Guerra-Fuentes, 2002). O padrão de desenvolvimento dos Iguania é muito similar com o descrito para outros grupos de lagartos. Foram encontradas algumas particularidades no desenvolvimento dos elementos dos arcos viscerais e da cápsula nasal dos táxons analisados. Algumas estruturas catilaginosas sugerem relações de parentesco entre grupos de Iguania.
This study comprises the description of the development of the cartilaginous and dermic skull of the following iguanid lizards: Anisolepis grilli (Leiosauridae), Hoplocercus spinosus (Hoplocercidae), Iguana iguana and of the Scleroglossa specie Tupinambis merianae (Teiidae). The description of the skull development of these taxons is unprecedented. The aim of this study is to describe and compare the development patterns of the lizards which make up the Iguania clade to the previously described patterns for other Squamata groups. The embryonic series of the above mentioned species were studied after clearing and staining. The descriptions were complemented by the description of the development of the cranium of Polychrus acutirostris (Polychrotidae) (Guerra-Fuentes, 2002). The development pattern of Iguania is very similar to previously described patterns for other lizard groups. A number of particular traits were found in the development of the elements of the visceral arches and of the nasal capsule of the studied taxons. Some cartilaginous structures suggest a close relation amongst groups of Iguania.

Annotation:

Lacertid lizards have long been a fruitful field of scientific enquiry with many people working on them over the past couple of hundred years. The scope of the field has steadily increased, beginning with taxonomy and anatomy and gradually spreading so that it includes such topics as phylogenetics, behaviour, ecology, and conservation. Since 1992, a series of symposia on lacertid lizards of the Mediterranean basin have taken place every three years. The present volume stems from the 2004 meeting in the Aeolian Islands. In the volume a wide range of island topics are considered, including the systematics of the species concerned, from both morphological and molecular viewpoints, interaction with other taxa, and conservation. The last topic is especially important, as island lizards across the world have often been vulnerable to extinction, after they came into contact with people and the animals they introduced. The volume also has papers on the more positive aspects of human influence, specifically the benign effects of traditional agriculture on at least some reptile species. Olive trees, cork oaks and the banks and walls of loose rocks that crisscross the Mediterranean scene all often contribute to elevated lizard populations. Nor is more basic biology neglected and there are articles on morphology, reproduction, development and thermoregulation. Finally, it is good to see one paper on non-Mediterranean species is included. For, to fully understand the lacertids of this region, it is necessary to appreciate their close relatives in Africa, Asia and the archipelagos of the northeastern Atlantic Ocean. (From Preface by E. Nicholas Arnold & Wolfgang Böhme)

During recent years the attention towards the effects of xenobiotic substances on wild nature has been steadily increasing. Literature reviews have revealed that active hormone-disintegrating substances might affect the reproduction of some wild animal species. Research shows anomalies of reproduction and development in various animal groups such as birds, fish, invertebrates and reptiles. Species inhabiting water and its surroundings cause the highest concern. Due to insufficient baseline information it is difficult to determine the extent of the problem in these wild populations on an ecological scale. The research described in this article is the first attempt to analyse xenobiotic substances and evaluate possible accumulation of pharmaceuticals in animals higher up in the food chain in Lithuania. This research tests new methods for to analyse for xenobiotics substances, which might be used in the future. Blood samples of 7 swans were examined using liquid chromatography, however, no xenobiotics were detected. Negative results do not eliminate the necessity for further investigate of larger samples, other species or to search for non-pharmaceutical xenobiotics.

Annotation:

Before the explosion of genetics research in the last century, embryonic development was largely studied from a mechanical perspective. Paired with genetic advances in understanding developmental signaling pathways and induction mechanisms, an important goal for understanding morphogenesis is to discover how the genome codes for changes in the mechanical movements of the embryonic cells. After formation of the zygote, a phase of rapid mitotic cell division is followed by epithelialization resulting in a cohesive sheet of cells termed the epiblast. During the next major phase of triploblastic development called gastrulation, a group of undifferentiated cells in the epiblast moves collectively to the embryonic midline and eventually gives rise to the three primary germ layers: endoderm, mesoderm, and ectoderm. At the primitive streak—the “organizing center” in amniotes (reptiles, birds, and mammals) which delineates anterior-posterior polarity—prospective endodermal and mesodermal precursors undergo epithelial-to-mesenchymal transition (EMT), internalization, and eventually organogenesis. “It is not birth, marriage, or death, but gastrulation which is truly the most important time in your life” (Lewis Wolpert, 1986).

Annotation:

From Jan. 1982 to Jan. 1987, 1213 patients were investigated either because of thrombotic episode(s) or thrombosis heredity. Diagnosis of DVT was confirmed by phlebography in 567 cases. Patients were first examined at least three months after an acute episode.Methods. Anti thrombin (AT) and plasminogen were assayed, using chromogenic substrates S-2238 and S-2251 , respectively, followed if values were low by immunochemical assessment. Furthermore, fibrinogen, thrombin and reptilase times, APTT, P…P were assessed. Only in the latter study period was protein C activity determined (129 cases). Fibrinolysis was assayed on fibrin plates after 20 min venous occlusion of the arms. In 1984 only, plasminogen activator inhibitor of endothelial cell type (PAI 1) was measured in most DVT patients (n=75).Results. DVT first occurred by the age of 45 in 337 patients, of whom five had AT deficiency (four classic and one abnormal), one had low and another abnormal plasminogen), one had abnormal fibrinogen, seven had lupus anticoagulants (LA), and 72 (21%) had decreased lysis on fibrin plates. Defective fibrinolysis was re-investigated in 42 patients; at check-up 13 were found to have normalised. Of the 75 patients from 1984, fibrinolysis on fibrin plates was normal in 50 cases, of which PAI 1 was normal in 44 and increased in six; of the remaining 25 patients from 1984, fibrin plate activity was decreased, PAI 1 was normal in five cases and increased in 20.DVT first occurred after the age of 45 in 230 patients, of whom none had pathological AT or protein C, five had LA, and one had abnormal plasminogen; of the 51 (22%) patients found to have defective fibrinolysis, 29 were re-investigated at check-up and 14 of them found to have normalised.Conclusion. Alterations in coagulation inhibitors are rare in patients with DVT. A more frequent finding, although intraindividual fluctuations occur, is defective vessel wall fibrinolysis.
