Are We Witnessing a Speciation Continuum? Evidence From Current and Past Gene Flow in the Genus Oritrophium s.s. (Asteraceae) From the Tropical High Andes

Molecular Ecology, EarlyView.
ABSTRACT Determining species boundaries is key for appropriately assessing biodiversity. However, the continuity of the speciation process makes delimiting species a difficult task, especially for recently diverged taxa. Furthermore, past introgression may leave traces that result in reticulate evolutionary patterns, challenging the estimation of ...

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Hyaluronic acid: A novel approach in regenerative/reconstructive periodontal therapy?

Periodontology 2000, EarlyView.
Abstract Background Although hyaluronic acid (HA) has long been used for many medical applications, only in recent years has it gained greater popularity in the field of periodontics because of its biological effects during wound healing. Even today, most clinicians are not aware that more than one type of HA exists and that the extent of its ...

Diversity of Amphidomataceae (Dinophyceae) in the Black Sea, including description of Amphidoma pontica sp. nov.

Phycological Research, EarlyView.
SUMMARY The dinoflagellate family Amphidomataceae includes the genera Azadinium and Amphidoma, several species of which are known producers of lipophilic toxins known as azaspiracids (AZAs). However, the diversity, abundance, and distribution of this important group of nanoplanktonic dinoflagellates in the Black Sea remain poorly understood. To address
