Selection of the promising accessions of jamun (Syzygium cumini (L.) skeels) based on pomological characterizations

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 470-480, January 2023., 2023
The obtained results are useful for designing conservation strategies for the germplasm as well as implementing breeding programs such as introducing cultivars with different goals such as early or late ripening and seedless, non‐astringent, large, and deeper color‐fruits.

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.

Coherent changes in wood charcoals, site occupation and lithic technology across the MIS 4/3 transition at Klein Kliphuis rock shelter, South Africa

open access: yesJournal of Quaternary Science, Volume 38, Issue 1, Page 38-48, January 2023., 2023
Abstract We explore the correspondence between changing palaeoenvironments, patterns of site use, and lithic technology at the rock shelter site Klein Kliphuis (South Africa) across the interval 65–55 000 years before present. This period coincides with the termination of Marine Isotope Stage (MIS) 4, and the disappearance of an iconic late Pleistocene

Assessing the influence of the solar orbit on terrestrial biodiversity [PDF]

open access: yesAstrophys.J. 768 (2013) 152, 2013
The terrestrial fossil record shows a significant variation in the extinction and origination rates of species during the past half billion years. Numerous studies have claimed an association between this variation and the motion of the Sun around the Galaxy, invoking the modulation of cosmic rays, gamma rays and comet impact frequency as a cause of ...

A new Megatheriinae skull (Xenarthra, Tardigrada) from the pliocene of northern venezuela – Implications for a giant sloth dispersal to central and North America [PDF]

open access: yes, 2018
A skull of a ground sloth from the Pliocene San Gregorio Formation documents a northern neotropical occurrence of a megatheriine that addresses issues on intraspecific variation and biogeography. The new specimen is broadly similar in size and morphology
