While most lizard species are polygamous, dominant males typically have greater access to females and copulate more frequently than submissive ones. Several studies suggest that applying assisted reproduction techniques this taxon could be an effective tool enhance conservation programs. Therefore, the proper selection of for breeding programs is crucial their overall success. In study, we report first time data on semen sperm quality from Mexican Sceloporus torquatus using commonly employed...
Environmental DNA (eDNA) is the that can be extracted from an environmental sample, enabling monitoring of whole biological communities across a large number samples, at potentially lower cost, which significantly benefit river conservation. A systematic mapping protocol was designed to investigate use eDNA in rivers, specifically terms research topics, geographic and taxonomic biases, as well information gaps. Furthermore, potential opportunities rivers possible paths find this kind on...
Sperm capacitation involves biochemical and physiological changes that enable sperm to fertilize the oocyte. It can be induced in vitro under controlled conditions simulate environment of oviduct. While extensively studied mammals, its approach lizards remains absent. Understanding mechanisms facilitate reproduction is essential for advancing implementation assisted reproductive technologies this group. Fifteen males Sceloporus torquatus were collected during early stage season. The isolated...
The aim of this study was to develop a non-invasive procedure stimulate ejaculation in median and small lizards for semen collection. After collection, we applied battery tests assess the motility (wave progressive), viability (eosin-nigrosin stain), morphology (normal/abnormal), sperm concentration ejaculate number, seminal volume colour. We obtained fluid from all males four species sceloporine (n = 30) one Mexican horned 7). found that had liquid-like consistency milky-white appearance....
En este trabajo se analizan la composición faunística, distribución y abundancia de los isópodos asociados a diferentes sustratos del Sistema Arrecifal Bajos Sisal Puerto Progreso. Las recolectas fueron realizadas manualmente, con el empleo SCUBA, en meses mayo junio 2012, 16 sitios muestreo, entre 1 20 m profundidad. Se obtuvieron organismos camas algas, esponjas, pedacería coral, madera, sedimento, boyas pilotes. cuantificaron 3,604 pertenecientes 5 subórdenes, superfamilias, 18 familias,...
Abstract Actual loss of lizard biodiversity continues, even with the implementation conventional conservation programs. An approach including assisted reproductive techniques such as sperm cryopreservation may contribute to management endangered species. We developed a method for in sceloporine lizards and compared response among studied Prior mating season, we obtained semen from adult males Sceloporus aeneus (n = 21), grammicus 20) torquatus 21) via pressure genital papilla. Volume...
Background. Perinatal depression (PND) is a clinical disease developed in any stage during the pregnancy and postpartum period with serious health economic implications. Objective. The aim of this work was to analyze via bibliometrics indicators Mexico’s production on PND provide view academic landscape comprehensive reference for subsequent research country. Method. Scopus Web Science (WoS) databases were used perform search peer reviewed papers related México. made following Preferred...
Sperm capacitation involves biochemical and physiological changes that enable sperm to fertilize the oocyte. It can be induced in vitro under controlled conditions simulate environment of oviduct. While extensively studied mammals, its approach lizards remains absent. Understanding mechanisms ensure reproduction is essential for advancing implementation assisted reproductive technologies this group. We aimed perform a analysis determine if capacitation-related were after incubation with...
Estradiol and progesterone have been recognized as important mediators of reproductive events in the female mainly via binding to their receptors. This study aimed characterize immunolocalization estrogen receptor alfa (ERα), beta (ERβ) (PR) ovarian follicles lizard Sceloporus torquatus. The localization steroid receptors has a spatio-temporal pattern that depends on stage follicular development. immunostaining intensity three was high pyriform cells cortex oocyte previtellogenic follicles....
The activins and inhibins are glycoproteins with a role in the follicular development of vertebrates, that found fluid somatic cells, different pattern among taxa. principal function activin (Act) is to modulate follicle-stimulating hormone (FSH) synthesis secretion, whereas inhibin (Inh) downregulates it. Both factors modulators intraovarian recruitment, oocyte maturation, cell proliferation, steroidogenic activity. Our aim was characterize immunolocalization Act Inh ovarian follicles...
