Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]

J Anim Ecol
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Regional economic resilience, trophic characteristics, and ecological analogies

Papers in Regional Science, Volume 102, Issue 6, Page 1127-1144, December 2023., 2023
Abstract Works on regional resilience have at times borrowed from the engineering and ecological framing of system resilience. In ecological contexts, system resilience is rooted in network structure and its characteristics. Here, we empirically investigate the relationship between regional economic resilience and regional trophic characteristics ...

Shedding light on trophic interactions: A field experiment on the effect of human population between latitudes on herbivory and predation patterns

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
This study tests how human pressure affects trophic interactions at different latitudes, being the first to demonstrate experimentally the opposite effects of human presence on trophic interactions between latitudes. Abstract Interactions between species within an ecosystem (e.g.

Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Taste for pollen comes in different shapes: Consumption by tadpoles from three divergent ecomorphotypes

Journal of Zoology, Volume 320, Issue 1, Page 42-52, May 2023., 2023
We studied pollen consumption and breakage of pollen grains by tadpoles of three different ecomorphotypes likely to influence ease of access to different feeding microhabitats. We found tadpoles adapted to feed on the water surface (where pollen is first available to aquatic food webs) to eat more pollen and break relatively more grains, which is ...

Large‐scale movement patterns in a social vulture are influenced by seasonality, sex, and breeding region

Ecology and Evolution, Volume 13, Issue 2, February 2023., 2023
Griffon vulture home‐range sizes and home‐range fidelity are affected by seasonality, sex, and breeding region. Vultures tend to move more during spring and summer, and females showed higher home‐range sizes than males, but lower home‐range fidelity.

Distribution of Oikopleura Dioica (Tunicata, Appendicularia) associated with a coastal frontal system (39°- 41°s) of the SW Atlantic ocean in the spawning area of Engraulis Anchoita anchovy [PDF]

, 2013
Among tunicates, the small planktonic appendicularians generally comprise a significant fraction of the mesozooplankton in frontal systems. The summer 2011 distribution (vertical and spatial) of Oikopleura dioica was studied in terms of abundance ...

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin [PDF]

, 2014
Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments.
