Testing peat humification analysis in an Australian context: identifying wet shifts in regional climate over the past 4000 years [PDF]

open access: yesMires and Peat, 2014
Peat humification analysis is presented as a robust palaeoclimatic proxy, suitable for use on mid–late Holocene peat sequences situated in the Southern Hemisphere.

Mangrove pollen of Indonesia and its suitability as a sea-level indicator [PDF]

open access: yes, 2007
I investigated the mangroves of Southeast Sulawesi, Indonesia, to assess their potential as proxies for reconstructing sea-level during the Holocene.

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

The search for the best airborne pollen monitoring locations

open access: yes
In Europe a quarter of the adult population and a third of all children suffer from allergenic airborne pollen thereby decreasing the quality of life. In order to ease the pollen induced symptoms mitigation measures can be applied.

The Late Glacial and Holocene development of vegetation in the area of a fossil lake in the Skaliska Basin (north-eastern Poland) inferred from pollen analysis and radiocarbon dating

open access: yesActa Palaeobotanica, 2013
The development of vegetation in the Skaliska Basin has been reconstructed on the basis of palynological analysis and radiocarbon dating (AMS technique) of 6 sites from the late phase of the Bolling- Allerod interstadial complex to modern times. Although

Component-resolved diagnosis of pollen allergy based on skin testing with profilin, polcalcin and lipid transfer protein pan-allergens [PDF]

open access: yes, 2009
BACKGROUND Allergy diagnosis needs to be improved in patients suffering from pollen polysensitization due to the existence of possible confounding factors in this type of patients.

BarnebyLives: An R package to create herbarium specimen labels and clean spreadsheets

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Accessioning herbarium specimens is labor intensive, yet remains vital for research in ecology, evolution, and conservation. As institutional support for herbaria declines, efficient tools are needed to streamline this process. The R package BarnebyLives was developed to assist collectors by supplementing collection notes, verifying ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.
