Evolution in reproductive tempo and investment across the Peromyscus radiation
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 13-27, January 1, 2023., 2023 In this review, we summarize diversity among Peromyscus species and populations in a number of reproductive traits. including litter size. We examine associations with environmental variation (map, right). We also use a large dataset compiled from lab‐held colonies (violin ploots, right) of Peromyscus to test for species‐ and population‐level ...

Comparison of the shape and temporal evolution of even and odd solar cycles [PDF]
A&A 636, A11 (2020), 2020 Results. The PCA confirms the existence of the Gnevyshev gap (GG) for solar cycles at about 40% from the start of the cycle. The temporal evolution of sunspot area data for even cycles shows that the GG exists at least at the 95% confidence level for all sizes of sunspots. On the other hand, the GG is shorter and statistically insignificant for the odd

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes
Molecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022 Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

Veterinary Medicine and Science, Volume 9, Issue 1, Page 191-202, January 2023., 2023 In this study, we supplemented the diet of breeding sows either with omega‐6 (control) or omega‐3 (experimental) polyunsaturated fatty acids and examined their effects on the antioxidant system and hormone levels of the animals. In the blood levels of molecules indicating oxidative stress we experienced slight changes, but the feeding of omega‐3 fatty ...

Characterization of the Estrous Cycle in Octodon degus [PDF]
Biology of Reproduction, 2010 We characterized the reproductive cycle of Octodon degus to determine whether reproductive maturation is spontaneous in juveniles and if ovarian cyclicity and luteal function are spontaneous in adults. Laboratory-reared prepubertal and adult females were monitored for vaginal patency and increased wheel-running.

Luteal Blood Flow and progesterone concentration during first and second postpartum estrous cycle in lactating dairy cows [PDF]
, 2019 The aim of the present study was to determine the differences in corpus luteum (CL) functionality between the first postpartum estrous cycle and the following cycle in lactating dairy cows. Luteal blood flow (LBF), luteal size and blood progesterone (P4)
