The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1502-1512, December 2025.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated

Climate change scenarios differentially modulate the impact of invasion in a native macrophyte species

open access: yesLimnology and Oceanography, Volume 70, Issue 10, Page 3016-3028, October 2025.
Abstract Biological invasion and climate change threaten freshwater ecosystems, potentially amplifying their impacts through interaction. However, empirical evidence on how future climate scenarios influence the invasion process and their interactive effects on native species remains limited.

Establishing ‘normal’ career longevity in professional footballers allows comparison to that of players with injuries and surgery

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 9, Page 3375-3388, September 2025.
Abstract Purpose To determine the ‘normal’ career longevity of male professional footballers and the factors that affect this in order to provide a baseline against which career longevity after injury can be measured. To demonstrate how these results can be used by comparing them with published career longevity rates after anterior cruciate ligament ...

Impact of Irrigation Treatment and Sowing Time on Lipoxygenase Activity and Seed Quality of Australian Sweet Lupin (Lupinus angustifolius L.)

open access: yesLegume Science, Volume 7, Issue 3, September 2025.
ABSTRACT The work aimed to demonstrate the impact of sowing time (2022 trial) and irrigation (2023 trial) on the expression of lipoxygenase (LOX) activity and crude protein and fat contents in five varieties of Australian sweet lupin or narrow‐leafed lupin (Lupinus angustifolius L.) and to investigate the relationship of LOX with linoleic acid and 2,2 ...
