The island syndrome describes morphological, behavioral, and life history traits that evolve in parallel in endemic insular organisms. A basic axiom of the island syndrome is that insular endemics slow down their pace of life. [...]
We tested this question in the fossil insular giant leporid Nuralagus rex. Using bone histology, we constructed both a continental extant taxon model derived from experimentally fluorochrome-labeled Lepus europaeus to calibrate life history events, and a growth model for the insular taxon. [...]

The adaptive radiation of hipparionins after their Old World dispersal was linked with a trend towards smaller body sizes. The appearance of the small-sized forms has usually been associated to open environments and grazing diets. [...]

18 p, 26.7 MB Limb bone histology records birth in mammals / Nacarino-Meneses, Carmen (Institut Català de Paleontologia Miquel Crusafont) ; Köhler, Meike (Institut Català de Paleontologia Miquel Crusafont)
The annual cyclicality of cortical bone growth marks (BGMs) allows reconstruction of some important life history traits, such as longevity, growth rate or age at maturity. Little attention has been paid, however, to non-cyclical BGMs, though some record key life history events such as hatching (egg-laying vertebrates), metamorphosis (amphibians), or weaning (suggested for Microcebus and the hedgehog).

236 p, 6.9 MB Growth dynamics and life history inferences in extant deer from histological analysis of bone tissues / Calderón Sánchez, Teresa ; Köhler, Meike, dir.
L'estudi de les històries de vida és fonamental per entendre els processos ecològics i evolutius d'una espècie. Un dels millors mètodes per a reconstruir el creixement ossi i fer inferències sobre la història de vida de vertebrats tant actuals com extints és l'anàlisi histològica de la microestructura, ja que recull la informació sobre el creixement incremental del teixit ossi.

The study of life histories is fundamental for understanding the ecological and evolutionary processes of a species. The histological analysis of bone microstructure is the most promising method for reconstructing bone growth and inferring the life histories of extinct and extant vertebrates because it records the incremental growth of bone tissue.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia ; Institut Català de Paleontologia Miquel Crusafont
Els hipparionins eren uns èquids tridàctils molt diversificats durant el Miocè superior a l'àrea circummediterrània, on alguns van esdevenir nans. Per la seva abundància, aquests són un grup clau en la recerca paleoecològica i l'anàlisi de patrons evolutius, tot i que encara cal conèixer millor la seva ecologia. [...]
Los hipparioninos eran unos équidos tridáctilos muy diversificados durante el Mioceno superior en el área circunmediterránea, donde algunos decrecieron en tamaño. Debido a su abundancia, estos constituyen un elemento clave en estudios paleoecológicos y de patrones evolutivos, aunque todavía queda mucho por conocer sobre su ecología. [...]
Hipparionins are a clade of tridactyl equids that greatly diversified during the late Miocene throughout the circum-Mediterranean area, with some taxa undergoing dwarfing. Due to their abundance, they have been the subject of several paleoecological studies and constitute a key mammalian group for exploring evolutionary patterns, although more research is necessary to better understand their ecology.

Body size (or its proxy: body mass) has a central position in the colossal web of interdependent biological variables of an organism. It shows correlation with lots of physiological, morphological, behavioral, ecological and life history features, and, thus, it affects the fitness of individuals and, ultimately, the biology and evolution of species.

El estudio de las life histories es de vital importancia porque proporciona evidencias sobre las condiciones ecológicas, biodiversidad, demografía, vulnerabilidad y otros muchos aspectos de la biología de las especies. [...]
Bone histology is a widely used tool to reconstruct vertebrate life histories, either by analysing primary bone tissue or by counting the number of growth marks (skeletochronology). However, it has long been considered that endotherms, unlike ectotherms, display a continuous or noncyclical bone growth, disabling bone histology for life history inferences in mammals. [...]
