Towards general deep-learning-based tree instance segmentation models [PDF]

open access: yesarXiv
The segmentation of individual trees from forest point clouds is a crucial task for downstream analyses such as carbon sequestration estimation. Recently, deep-learning-based methods have been proposed which show the potential of learning to segment trees.

Passiflora quimiana, a new species from the Cordillera del Cóndor: Ecuador's far‐flung frontier

open access: yesNordic Journal of Botany, EarlyView.
A new species of Passiflora subgenus Decaloba, supersect. Decaloba, from the Cordillera del Cóndor in Ecuador, is described and illustrated, with its morphological similarities to other species being discussed in this paper. Passiflora quimiana exhibits the unique combination of narrow ovate to long‐oval leaves and small foliaceous bracts ...

Decision support for sustainable forest harvest planning using multi-scenario multiobjective robust optimization [PDF]

open access: yesarXiv
Sustainable forest management requires handling uncertainty introduced from various sources, considering different conflicting economic, environmental, and social objectives, and involving multiple decision-making periods. This study proposes an interactive and intuitive decision-support approach for sustainable, robust forest harvest scheduling in ...

Unapparent trees: escaping enemies in time by being discreet, unpredictable and inaccessible

open access: yesOikos, EarlyView.
For half a century, biologists considered trees as particularly apparent to their enemies. But why then do some trees escape herbivorous enemies by bursting buds either too early or too late, leading to phenological mismatch? We hypothesize that such mismatches occur on trees that are unapparent in time – those that burst buds ‘discreetly' (slowly) and

Non‐native species affect the long‐term dynamics of native stream fish assemblages

open access: yesOikos, EarlyView.
Characterizing the temporal changes of biotic communities and disentangling the importance of their driving mechanisms are central themes in ecology and environmental management. Non‐native species have multiple adverse impacts on native communities and species.

Nephroprotective Effects of Fraxinus Hookeri Wenz. Against Renal Toxicity and DNA Oxidative Damages Induced by CCl4 in Rats

open access: yesChemistryOpen, EarlyView.
This study evaluates the nephroprotective potential of Fraxinus hookeri Wenz. (F. hookeri), a medicinal plant of the Oleaceae family, against CCl4‐induced oxidative stress. The findings demonstrate its ability to restore antioxidant defenses, renal function markers, and DNA integrity while reducing lipid peroxidation and histopathological damage.
