Effects of crude oil exposure on bioaccumulation of polycyclic aromatic hydrocarbons and survival of adult and larval stages of gelatinous zooplankton. [PDF]

open access: yesPLoS ONE, 2013
Gelatinous zooplankton play an important role in marine food webs both as major consumers of metazooplankton and as prey of apex predators (e.g., tuna, sunfish, sea turtles).

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...

Benthoplanidae, a new family of benthic ctenophores (Platyctenida), based on morphological and genetic data

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 2, Page 387-400, March 2026.
The benthic ctenophore Benthoplana meteoris (adults left and bottom, planktonic juveniles to the top right), type species for the genus, which in turn is type for the newly erected family: Benthoplanidae (Ctenophora, Platyctenida). Abstract We present a phylogenetic analysis of benthic ctenophores of the order Platyctenida, sampling all but one genus ...

Assessing the success of a horizon scanning approach in predicting invasive non‐native species arrival

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
We conclude that horizon scanning provides a rapid, affordable and successful mechanism to predict the arrival of high‐risk INNS. We highlight the importance of citizen science, including biological recording, and of local expertise for detecting and documenting arrival of INNS.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.
