An Evolutionary Perspective on Human Cross-sensitivity to Tree Nut and Seed Allergens [PDF]

open access: yes, 2015
Tree nut allergies are some of the most common and serious allergies in the United States. Patients who are sensitive to nuts or to seeds commonly called nuts are advised to avoid consuming a variety of different species, even though these may be ...

Lineage‐specific phylogenetic structure of boreal habitats suggests different assembly processes across phylogenetic and spatial scales

open access: yesEcography, Volume 2025, Issue 12, December 2025.
The phylogenetic distance among species in a community (community phylogenetic structure) has been used to infer deterministic and stochastic assembly processes, albeit with criticisms. The effect of phylogenetic scale (old versus young lineages) and spatial scale on measures of CPS are rarely tested simultaneously, especially in the boreal biome, yet ...

Revision of Pycnandra subgenus Sebertia (Sapotaceae) and a generic key to the family in New Caledonia [PDF]

open access: yes, 2010
The satellite genus Sebertia (Sapotaceae, Chrysophylloideae) in New Caledonia is here recognized as Pycnandra subgenus Sebertia, a group comprising only two species. Pycnandra canaliculata is described and illustrated as new from the south part of Grande

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees

open access: yesNew Phytologist, Volume 248, Issue 6, Page 3297-3311, December 2025.
Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Evaluation of the in vivo mutagenic potential of hydroalcoholic extracts of the northern highbush blueberry (Vaccinium corymbosum L. Ericales, Ericaceae) on peripheral blood cells of Swiss mice (Mus musculus Rodentia, Muridae)

open access: yesGenetics and Molecular Biology, 2008
The northern highbush blueberry (Vaccinium corymbosum L. Ericales, Ericaceae) is very rich in anthocyanins, natural pigments which have strong antioxidant properties and potential health benefits, resulting in the worldwide use the blueberry as a ...

Global variability in hydraulic traits and water use strategies of mountain shrubs and dwarf shrubs

open access: yesPlant Biology, Volume 27, Issue 7, Page 1253-1270, December 2025.
Shrubs show a wide range of hydraulic strategies to achieve a balanced and favourable water status in mountain areas. Abstract Shrubs are perennial, multi‐stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain

Marked Ericales diversity in late Oligocene–Early Miocene palynofloras from northern Thailand suggests stratified mountain forests

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 6, Page 1458-1480, November 2025.
Ericalean pollen was recovered from the Ban Pa Kha Subbasin, Li Basin, northern Thailand. Based on the ecological preferences of their modern analogs, the assemblage of dispersed ericalean pollen likely derives from more than one vegetation type and possibly from different vertical zones of mountainous areas.

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]

open access: yes, 2018
Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

New records of Pouteria macrocarpa (Sapotaceae) from the Brazilian Atlantic forest

open access: yesRodriguésia
We present the first voucher-based record of Pouteria macrocarpa for Brazilian Atlantic forest and extend the occurrence area of it. Besides, a brief taxonomic description, an identification key for lignified-fruits Pouteria species, and information ...

Ecology, ethnobotany and ethnopharmacology of Argan tree (Argania spinosa) [PDF]

open access: yes, 2009
Argania spinosa es una especie leñosa endémica del suroeste de Marruecos que ha jugado un papel fundamental, desde un punto de vista etnobotánico, en la economía local de los pueblos bereberes.
