Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

Journal of Phycology, EarlyView.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

Lake Baikal amphipods and their genomes, great and small

Вавиловский журнал генетики и селекции
Endemic amphipods (Crustacea: Amphipoda) of Lake Baikal represent an outstanding example of large species flocks occupying a wide range of ecological niches and originating from a handful of ancestor species.

Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

Journal of Phycology, EarlyView.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

Multi-view light-sheet imaging and tracking with the MaMuT software reveals the cell lineage of a direct developing arthropod limb

eLife, 2018
During development, coordinated cell behaviors orchestrate tissue and organ morphogenesis. Detailed descriptions of cell lineages and behaviors provide a powerful framework to elucidate the mechanisms of morphogenesis. To study the cellular basis of limb

Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

Journal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

Maximal Swimming Speed Explains Differences in Habitat Use Among Invasive Ponto‐Caspian Dikerogammarus Species (Crustacea, Amphipoda)

Journal of Zoology, EarlyView.
The three invasive Ponto‐Caspian Dikerogammarus species (D. bispinosus, D. haemobaphes, and D. villosus) show niche differentiation along the current velocity gradient. In the present study, we experimentally measured their maximal swimming speeds to test whether they coincide with their tolerances for currents.

Seawater acidification more than warming presents a challenge for two Antarctic macroalgal-associated amphipods [PDF]

, 2016
Elevated atmospheric pCO2 concentrations are triggering seawater pH reductions and seawater temperature increases along the western Antarctic Peninsula (WAP).

Macroinvertebrates Associated with Macroalgae within Integrated Multi-Trophic Aquaculture (IMTA) in Earthen Ponds: Potential for Accessory Production

Journal of Marine Science and Engineering
The present work aims to evaluate the macroinvertebrate community associated with macroalgae in earthen pond systems to better understand their potential in detritus recycling and as an accessory production. Sampling took place on the settling pond of an
