Strong intraspecific trait variation in a tropical dominant tree species along an elevational gradient

open access: yesPlant Diversity, 2020
Functional trait variation of plant species includes both inter- and intraspecific variation; however, trait-based plant ecology generally considers only interspecific variation while ignoring intraspecific variation.

Synchronous population dynamics in California butterflies explained by climatic forcing [PDF]

open access: yesRoyal Society Open Science, 2017
A long-standing challenge for population biology has been to understand why some species are characterized by populations that fluctuate in size independently, while populations of other species fluctuate synchronously across space.

Interspecific variations in the gastrointestinal microbiota in penguins [PDF]

open access: yesMicrobiologyOpen, 2013
AbstractDespite the enormous amount of data available on the importance of the gastrointestinal (GI) microbiota in vertebrate (especially mammals), information on the GI microbiota of seabirds remains incomplete. As with many seabirds, penguins have a unique digestive physiology that enables them to store large reserves of adipose tissue, protein, and ...

Osteology of Vertebral Column and Caudal Skeleton of Iranian Aphaniid Species (Teleostei: Cyprinodontiformes, Aphaniidae) [PDF]

open access: yesJournal of Genetic Resources, 2023
In this study, a comparative analysis of the vertebral column and the caudal skeleton of 245 specimens of 10 Aphanius and three Aphaniops species was conducted based on X-ray imaging, and interspecific variation of these characters was examined.

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

open access: yes, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Tradeoffs in the evolution of caste and body size in the hyperdiverse ant genus Pheidole. [PDF]

open access: yesPLoS ONE, 2012
The efficient investment of resources is often the route to ecological success, and the adaptability of resource investment may play a critical role in promoting biodiversity.

Phylogeny-Related Variations in Venomics: A Test in a Subset of Habu Snakes (Protobothrops)

open access: yesToxins, 2023
We conducted a comparative analysis to unveil the divergence among venoms from a subset of Old World habu snakes (Protobothrops) in terms of venomic profiles and toxicological and enzymatic activities.

Intraspecific variability modulates interspecific variability in animal organismal stoichiometry. [PDF]

open access: yes, 2014
Interspecific differences in organismal stoichiometry (OS) have been documented in a wide range of animal taxa and are of significant interest for understanding evolutionary patterns in OS.

Leaf trait variation in species-rich tropical Andean forests

open access: yesScientific Reports, 2021
Screening species-rich communities for the variation in functional traits along environmental gradients may help understanding the abiotic drivers of plant performance in a mechanistic way.

Root morphological and physiological traits and arbuscular mycorrhizal fungi shape phosphorus-acquisition strategies of 12 vegetable species

open access: yesFrontiers in Plant Science, 2023
Trait plasticity and integration mediate vegetable adaptive strategies. However, it is unclear how patterns of vegetables in root traits influence vegetable adaptation to different phosphorus (P) levels.
