Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Biologia Funcional vs. Biologia Evolutiva

open access: yes, 2001
RESUMEN: La distinción propuesta por Ernst Mayr y François Jacob entre biología funcional y biología evolutiva es una clave fundamental para un tratamiento claro y concluyente de dos problemas que, recurrentemente, se colocan en el ámbito de la Filosofía de la Biología: aquel que atañe al posible carácter teleológico de las explicaciones biológicas y ...

It all started with Margalef's paper of 1951 [PDF]

open access: yes, 2012
As early as 1951, Margalef speculated on the production of soluble phosphatases by zooplankton; "entomostracans" were producing their own phosphatases and so contributing to phosphate regeneration.

Determining the timeline of gonadal and genital differentiation in male and female equine fetuses allows for early detection and intervention in malformations

open access: yesThe Anatomical Record, EarlyView.
Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.
