Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Effects of recreational activity on Acorn Barnacle (Tetraclita squamosa rufotincta) in the Red Sea

open access: yesEuropean Journal of Ecology, 2019
Environmental recreation is a fast growing industry. However, in many cases the consequences for the environment are ignored. Eilat is just such a case wherein tourism is the mainstay of the city and the Red Sea is the main attraction.

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

open access: yesIntegrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Bored to Death: Community-Wide Effect of Predation on a Foundation Species in a Low-Disturbance Arctic Subtidal System. [PDF]

open access: yesPLoS ONE, 2015
The strength of top-down control by consumers is predicted to decrease with latitude, but most data confirming this assumption come from latitudes

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

open access: yesMarine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Gaining ground: survival of native estuarine fauna exposed to recycled glass sand, a potential material for coastal restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Objectives The aim of this research is to develop an understanding of the potential for using recycled glass sand as a resource for restoring Louisiana's coastline by testing the effects of exposure of native estuarine fauna to recycled glass sand and other sand treatments in a laboratory environment.

Ghost Pots are the Result of Barnacles

open access: yes, 2021
Barnacles attach themselves to crab pot buoys. These barnacles have detrimental effects on watermen, recreational boaters, and most importantly the environmental health of the river. Heavy barnacle growth on the buoys results in a weighted buoy.
