Phenotypic Variation of Oak Species (Quercus spp.) Reveals Adaptive Strategies Across Natural and Semi‐Artificial Oak Stands

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Our findings highlight the significant impact of forest management on morphological traits, particularly the differences observed between the semi‐artificial forest at Zijin Mountain and the natural forest at Youhua Village. The study underscores the influence of both biotic and abiotic factors on phenotypic traits, with notable implications for forest

The Urea Cycle in Connection to Polyamine Metabolism in Higher Plants: New Perspectives on a Central Pathway

open access: yesPhysiologia Plantarum, Volume 177, Issue 3, May/June 2025.
ABSTRACT The ornithine‐urea cycle is a biochemical pathway primarily found in animals, where it plays a crucial role in the re‐assimilation of ammonium and the removal of excess nitrogen in the form of urea. In lower photosynthetic eukaryotes, it contributes to metabolic responses during episodes of high nitrogen availability.

Network structure and taxonomic composition of tritrophic communities of Fagaceae, cynipid gallwasps and parasitoids in Sichuan, China 中国四川的壳斗科、瘿蜂、和寄生蜂之三級营养生物群落的结构和组成

open access: yesInsect Conservation and Diversity, Volume 17, Issue 6, Page 1046-1071, November 2024.
We quantified previously unstudied tritrophic gall communities on Fagaceae in Sichuan, China, testing for ‘bottom‐up’ effects of host plant diversity on plant–herbivore and plant–parasitoid interactions. We sampled 176 cynipid gall morphotypes from 23 host plant species, yielding 64 parasitoid morphospecies.

Rapid terrace incision and Quaternary landscape evolution in central Patagonia

open access: yesJournal of Quaternary Science, Volume 39, Issue 2, Page 208-223, February 2024.
Abstract The debate over isostatic uplift versus discharge as drivers of Quaternary river incision is explored here through geospatial analysis of a ~250‐m‐relief terrace sequence from the Río Pinturas (Argentine Patagonia). The geomorphic setting of the Cañadon Caracoles reach allows evaluation of discharge as a driver of terrace incision because ...
