Priority effects in coral–macroalgae interactions can drive alternate community paths in the absence of top‐down control

open access: yesEcology, Volume 103, Issue 12, December 2022., 2022
Abstract The outcomes of species interactions can vary greatly in time and space with the outcomes of some interactions determined by priority effects. On coral reefs, benthic algae rapidly colonize disturbed substrate. In the absence of top‐down control from herbivorous fishes, these algae can inhibit the recruitment of reef‐building corals, leading ...

Parasitoid wasps as effective biological control agents

open access: yesJournal of Integrative Agriculture, 2019
Biological control (biocontrol) is a safe, sustainable approach that takes advantage of natural enemies such as predators, parasitic insects or pathogens to manage pests in agroecosystems. Parasitoid wasps, a very large evolutionary group of hymenopteran

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Root hemiparasitic plants are associated with more even communities across North America

open access: yesEcology, Volume 103, Issue 12, December 2022., 2022
Abstract Root hemiparasitic plants both compete with and extract resources from host plants. By reducing the abundance of dominant plants and releasing subordinates from competitive exclusion, they can have an outsized impact on plant communities. Most research on the ecological role of hemiparasites is manipulative and focuses on a small number of ...

Bending performance changes during prolonged canine eruption in saber‐toothed carnivores: A case study of Smilodon fatalis

open access: yesThe Anatomical Record, EarlyView.
Abstract The canine of saber‐toothed predators represents one of the most specialized dental structures known. Hypotheses about the function of hypertrophied canines range from display and conspecific interaction, soft food processing, to active prey acquisition.

Assessing flower‐visiting arthropod diversity in apple orchards through metabarcoding of environmental DNA from flowers and visual census

open access: yesEnvironmental DNA, Volume 5, Issue 1, Page 117-131, January 2023., 2023
The diversity of flower‐visiting arthropods in four Danish apple orchards was assessed using molecular (metabarcoding) and non‐molecular techniques. The aim was to obtain a broader overview of arhtropod communities present to support future management practices towards more sustainable agricultural systems.
