Species with wide distribution, generally show variations in life history characteristics, which can be attributed to environmental causes. In this study, we analyzed the reproductive cycle and reproductive characteristics from three populations (Atlapexco, San Pablo Tetlapayac, and Santa Catarina) of the lizard Sceloporus variabilis from central Mexico. The specific goal of this study was to e...

Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of cotton (Gossypium spp.) in the western United States that injures ßoral buds (squares) and developing fruit (bolls). Levels of Lygus-induced damage to cotton can vary by Lygus ages or gender, and these variations complicate interpretation of studies designed to elucidate Lygus and cotton interactions. Variations in observed injury may ...

Cancer therapies are known to alter the reproductive potential in cancer patients. Due to improved survival rates in cancer patients of reproductive age, considerations of the long-term effects of cancer therapy have become more significant. Oncofertility is a new discipline in medicine that deals with maintaining the reproductive potential of cancer patients while they are receiving gonadotoxi...

The Outstanding Contributions to the International Society for Computational Biology (ISCB) Award was launched in 2015 to recognize individuals who have made lasting and valuable contributions to the Society through their leadership, service, and educational work, or a combination of these areas. Fran Lewitter is the 2017 winner of the Outstanding Contributions to ISCB Award and will be recogni...

Freshwater fish that live exclusively in rivers are at particular risk from fragmentation of the aquatic system, mainly the species that migrate upriver for reproduction. That is the case of Salminus hilarii, an important migratory species currently classified as "almost threatened" in the São Paulo State (Brazil), facing water pollution, dam construction, riparian habitat destruction and envir...

OBJECTIVE The aim of this study was to assess which of the basal ovarian reserve markers provides the best reflection of the changes occurring in ovarian function over time (i.e., reproductive aging). DESIGN Prospective longitudinal study. SETTING Healthy volunteers in an academic research center. PATIENT(S) Eighty-one women with normal reproductive performance during the course of their ...

OBJECTIVE To examine the effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility. Prospective study. SETTINGS Infertility clinic at a tertiary care academic institution. PATIENT(S) Ninety-two infertile men with normal female partners. Sixteen fertile donors served as the control group. INTERVENTION(S) Standard semen ...

Bisphenol-S (BPS) is a new bisphenol-A substitute widely used in many plastic products. Bisphenol-A as a main member of bisphenol family has been known as an endocrine system disrupter chemical compound. Like other members of bisphenol family, there is public health concern about the toxic effects of BPS on reproductive system, thus, we examined BPS effects on in vitro fertilization (I...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
