Genetic diversity and identification of clonal ramets in the clonal seed orchard of sessile oak (Quercus petraea (Matt.) Liebl.)

open access: yes
U ovom radu uzorkovano je 156 rameta 52 klona hrasta kitnjaka iz klonske sjemenske plantaže „Novoselci“. Klonska sjemenska plantaža osnovana je pomoću vegetativnih kopija izabranih majčinskih stabala. Kopije su proizvedene cijepljenjem.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Harvesting of two alpine Artemisia: Effects of an amateur practice on wild plant dynamics

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wild plants are consumed all over the world, and knowledge of the effects of harvesting is necessary to ensure the sustainability of this activity. Our 3‐year study of two closely related alpine Artemisia species in the Southern Alps revealed a positive impact of harvesting at the plant scale and on the short term.

Riparian Failure: Damming and Flow Stabilization Exclude Cottonwood Colonization Along a Dryland River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The Marias River flows from Glacier National Park through northcentral Montana, and into the Missouri River. Annual flows gradually declined from 1902 to 2024 (~3.2%/decade) and the 1952 Tiber Dam and Lake Elwell reservoir were operated to attenuate peak flows and stabilize downstream flows year‐round.

Retrospective image analysis for long‐term demography using Google Earth imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
