Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Biodiversity and spatial distribution of medusae in the Magellan Region (Southern Patagonian Zone)

Latin American Journal of Aquatic Research, 2014
Epipelagic medusae collected in the Magellan Region (Southern Patagonian Zone) during spring 2009 were analyzed. A total of 27 species of medusae were identified (25 hydromedusae and 2 scyphomedusae).

Brazil's Invisible Invaders: Are Craspedacusta Jellyfish a Ticking Ecological Bomb?

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The invasive freshwater jellyfish Craspedacusta sowerbii, likely of Asian origin, is globally distributed, yet its invasion history in South America remains poorly understood. Following a mass mortality event of tilapia (Oreochromis niloticus) during a jellyfish bloom in Paraná, Brazil, in March 2022, we conducted morphological and molecular ...

Cannibal Salvage Expenditure: The Subaltern Style of the Urban Peruvian Amazon

Antipode, Volume 58, Issue 2, March 2026.
ABSTRACT This paper explores the political ecology of subaltern existence at the urban cutting edge of our apocalyptic present, in the case of Iquitos in the Peruvian Amazon. Through an ethnographically surrealist montage of multiple elements across the themes of accumulation, architecture, and art, cannibal salvage expenditure emerges as a subversive ...

Modeling Phenotypic Trait Variation and Plasticity in Elymus elymoides to Guide Climate‐Informed Seed Transfer

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Information on climate‐associated phenotypic variation is essential for sourcing seed that matches restoration site conditions. Spatially explicit seed transfer models can effectively deliver this information. However, standard modeling approaches often do not provide flexibility for practical considerations and may not capture highly complex ...

Combining Historical and Ecological Methods Provides New Insights for the Recognition of Biogeographical Areas and Their Relationships: The Case of the Gulf of Mexico

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim Biogeographical regionalisation is an evolutionary system of nested areas representing the geographic organisation of life on the planet, which is fundamental for understanding basic and applied aspects related to the ecology, evolution and conservation of biotas and their habitats.

Prey Capture Ecology of the Cubozoan Carukia barnesi.

PLoS ONE, 2015
Adult Carukia barnesi medusae feed predominantly on larval fish; however, their mode of prey capture seems more complex than previously described. Our findings revealed that during light conditions, this species extends its tentacles and 'twitches' them ...

Pacing Early Mars Sedimentary Rock Formation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Mars' sedimentary rock record documents past surface and/or near‐surface liquid water. However, paleoclimate models struggle to explain conditions warm enough for past liquid water. One hypothesis is transient warming by H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2}$ collision‐induced absorption (CIA) (H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2 ...
