Different population trajectories of two reef-building corals with similar life-history traits.

J Anim Ecol 2021 05 17;90(5):1379-1389. Epub 2021 Mar 17.

Institute for Global Ecology, Florida Institute of Technology, Melbourne, FL, USA.

Increases in the frequency and intensity of acute and chronic disturbances are causing declines of coral reefs world-wide. Although quantifying the responses of corals to acute disturbances is well documented, detecting subtle responses of coral populations to chronic disturbances is less common, but can also result in altered population and community structures. We investigated the population dynamics of two key reef-building Merulinid coral species, Dipsastraea favus and Platygyra lamellina, with similar life-history traits, in the Gulf of Eilat and Aqaba, Red Sea from 2015 to 2018, to assess potential differences in their population trajectories.

Increased Osteoclast and Decreased Osteoblast Activity Causes Reduced Bone Mineral Density and Quality in Genetic Hypercalciuric Stone-Forming Rats.

JBMR Plus 2020 Apr 25;4(4):e10350. Epub 2020 Feb 25.

Division of Nephrology University of Rochester School of Medicine Rochester NY USA.

To study human idiopathic hypercalciuria (IH), we developed an animal model, genetic hypercalciuric stone-forming (GHS) rats, whose pathophysiology parallels that in IH. All GHS rats form kidney stones and have decreased BMD and bone quality compared with the founder Sprague-Dawley (SD) rats. To understand the bone defect, we characterized osteoclast and osteoblast activity in the GHS compared with SD rats. Read More

Coral microbiome composition along the northern Red Sea suggests high plasticity of bacterial and specificity of endosymbiotic dinoflagellate communities.

Microbiome 2020 02 3;8(1). Epub 2020 Feb 3.

Coral Reef Research Unit, School of Life Sciences, University of Essex, Colchester, CO4 3SQ, UK.

Background: The capacity of reef-building corals to tolerate (or adapt to) heat stress is a key factor determining their resilience to future climate change. Changes in coral microbiome composition (particularly for microalgal endosymbionts and bacteria) is a potential mechanism that may assist corals to thrive in warm waters. The northern Red Sea experiences extreme temperatures anomalies, yet corals in this area rarely bleach suggesting possible refugia to climate change. Read More

Mycoses 2019 May;62(5):466-474

Westerdijk Fungal Biodiversity Institute, Utrecht, The Netherlands.

Trichophyton schoenleinii is an anthropophilic dermatophyte usually causing tinea favosa.
