Novel trophic subsidies from recreational angling transform the trophic ecology of freshwater fishes
Journal of Applied Ecology, 2022 1. Angling is a globally popular leisure activity. There are over 31 million anglers in Europe, many of which target species of the Cyprinidae family in lowland freshwater ecosystems using methods generally involving bait (e.g.

Biological Invasions, 2021 Invasive non-native crustaceans are a biodiversity and management concern in the Mediterranean Sea. The Atlantic blue crab (Callinectes sapidus) was first recorded in the Mediterranean Sea in 1949, but may have arrived as early as in the 1930’s.

Glimmers of hope in large carnivore recoveries
Scientific Reports, 2022 In the face of an accelerating extinction crisis, scientists must draw insights from successful conservation interventions to uncover promising strategies for reversing broader declines. Here, we synthesize cases of recovery from a list of 362 species of

Could an event of extreme drought (2019-2020) affect the feeding ecology of Bubo magellanicus (Gmelin 1788) (Strigiformes: Strigidae) in a Mediterranean region of Chile? [PDF]
PeerJ, 2023 Global warming generates changes in environmental conditions, affecting the spatial-temporal dynamics of precipitation and temperature. Droughts, events of low rainfall, are becoming more frequent and severe.

Not all jellyfish are equal: isotopic evidence for inter- and intraspecific variation in jellyfish trophic ecology [PDF]
PeerJ, 2015 Jellyfish are highly topical within studies of pelagic food-webs and there is a growing realisation that their role is more complex than once thought.

Integrating siphonophores into marine food‐web ecology
Limnology and Oceanography Letters, 2022 Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column.
