Interspecific variation in the elemental and stable isotope content of seagrasses in South Florida [PDF]
Marine Ecology - Progress Series, 2009 The elemental (C, N, and P) and isotope (δ13C, δ15N) content of leaves of the seagrasses Thalassia testudinum, Halodule wrightii, and Syringodium filiforme were measured across a 10 000 km2 survey of the seagrass communities of South Florida, USA, in ...

Synchronous population dynamics in California butterflies explained by climatic forcing [PDF]
Royal 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]
MicrobiologyOpen, 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]
Journal 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.

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