Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

open access: yesAmerican Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Green Turtle Chelonia mydas Spatial Use Within the Gorgona National Natural Park, Colombian Pacific: Implications for Local Conservation

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study explores the spatial ecology of green turtles within the Gorgona National Natural Park (GNNP), providing insights into habitat preferences, movement patterns, and conservation implications for this vulnerable species in the Colombian Pacific. Ten green turtles were tracked in the GNNP using satellite telemetry, with tracking duration ranging

Precipitation Modulates the Impact of Human Activities on Riverine Food Webs Revealed by Environmental DNA

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The effects of human activities on ecological networks are associated with climate, with increased precipitation weakening their negative impact. ABSTRACT The functionality of global rivers has been adversely affected by environmental pollution and habitat degradation.

The taxonomy of the Chlorophyta. II [PDF]

open access: yesBritish Phycological Journal, 1971
The taxonomy of all the algal groups possessing both chlorophyll a and b is discussed for the levels above that of the family. Much of the discussion is related to previously conceived taxa but some new combinations are proposed. The subdivision of ‘green’ algae into Euglenophyta, Prasinophyta, Charophyta and Chlorophyta is discussed in the light of ...

Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...
