Xtrawood: refining estimation of tree above ground biomass using wood specific gravity variations and tree structure [PDF]

open access: yes, 2016
Background: Tree above ground biomass (AGB) is currently estimated by tree-level allometrical models that take into account, tree volume estimated from proxy variables of tree size (DBH) and species average wood specific gravity (WSG).

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Pan-African Genetic Structure in the African Buffalo (Syncerus caffer): Investigating Intraspecific Divergence [PDF]

open access: yesPLoS ONE, 2013
Le buffle d'Afrique (Syncerus caffer) présente une extrême variabilité morphologique, ce qui a conduit à des controverses sur la validité et le statut taxonomique des différentes sous-espèces reconnues. La présente étude vise à les clarifier en déduisant la distribution spatiale panafricaine de la diversité génétique, en utilisant un ensemble complet ...

Insights into chloroplast genome structure, intraspecific variation, and phylogeny of Cyclamen species (Myrsinoideae)

open access: yesScientific Reports, 2023
AbstractSpecies from the flowering plant genus Cyclamen are popular amongst consumers. In particular Cyclamen persicum Mill. has been significantly used commercially, and certain small flowering species such as Cyclamen hederifolium and Cyclamen coum are gradually growing in popularity in the potted flower market.

Exploring intraspecific life history patterns in sharks [PDF]

open access: yes, 2006
Marine ecosystems compose the major source (85%) of world fisheries production (Garcia and Newton, 1997). Although only a few fish species tend to dominate fishery catches (Jennings et al., 2001), a large diversity of fishes representing varied ...

Practice-oriented controversies and borrowed epistemic credibility in current evolutionary biology: phylogeography as a case study [PDF]

open access: yes, 2013
Although there is increasing recognition that theory and practice in science are intimately intertwined, philosophy of science perspectives on scientific controversies have been historically focused on theory rather than practice.

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

TRY plant trait database - enhanced coverage and open access [PDF]

open access: yes, 2020
Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits ...

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
