A single long day triggers follicle growth in captive female great tits (Parus major) in winter but does not affect laying dates in the wild in spring. [PDF]

open access: yesPLoS ONE, 2012
In many forest passerine bird species, rapid climate warming has led to a phenological mismatch between the period of maximum nestlings' food requirements and the period of maximum food availability (seasonal caterpillar biomass peak) due to an ...

Gonadal development and silvering of the Japanese Eel (Anguilla japonica) in the Yangtze River during downstream migration

open access: yesAquaculture and Fisheries, 2017
The Yangtze River and its branches are important habitats for the Japanese Eel (Anguilla japonica), however, there are few data on gonadal development and silvering indices of eels during the downstream spawning migration. This study investigates gonadal

Gonad development: Signals for sex [PDF]

open access: yesCurrent Biology, 2001
The formation of testes or ovaries in the mammalian embryo is critical in determining sexual identity and the ability to reproduce. Recent studies have begun to illuminate the cellular signalling events required for development of functional testes.

Live imaging of Drosophila gonad formation reveals roles for Six4 in regulating germline and somatic cell migration [PDF]

open access: yes, 2007
Background: Movement of cells, either as amoeboid individuals or in organised groups, is a key feature of organ formation. Both modes of migration occur during Drosophila embryonic gonad development, which therefore provides a paradigm for understanding ...

Modeling Human Gonad Development in Organoids

open access: yesTissue Engineering and Regenerative Medicine, 2022
Our learning about human reproductive development is greatly hampered due to the absence of an adequate model. Animal studies cannot truthfully recapitulate human developmental processes, and studies of human fetal tissues are limited by their availability and ethical restrictions.
