Divergent Responses of Fungal Communities to Vegetation Structural Complexity in Degraded Roadside Slopes Across Climatic Gradients

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how climate and vegetation structural complexity jointly shape fungal communities is essential for effective roadside slope restoration. To address this, we examined restoration effects on fungal diversity, community composition, and ecological networks across three climatically distinct regions: dry‐hot valley, subalpine, and ...

A systematic 15N‐amino‐acid tracer framework to identify sources of pelagic marine organic matter

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurately tracing organic matter sources in marine systems remains challenging, particularly where natural and anthropogenic inputs coexist. Compound‐specific stable isotope analysis of amino acids (CSIA‐AA) offers strong potential for organic matter source discrimination, but its application is limited by the small number of validated δ15N ...

Trophic niche overlap in coralline algae- and coral-dominated rocky-bottom subtidal communities

Marine Pollution Bulletin
We investigated trophic structures in rocky subtidal ecosystems transitioning from canopy-forming to barren states across coastlines with varying oceanographic conditions. We examined stable isotopes and functional traits of common invertebrate and fish taxa to understand the food-web consequences. We hypothesized that resource exploitation patterns of

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Variación interpoblacional y ontogenética en la dieta de la rana llorona Physalaemus albonotatus (Anura: Leiuperidae) Interpopulation and ontogenetic variation in the diet of the menwig frog Physalaemus albonotatus (Anura: Leiuperidae)

Revista Mexicana de Biodiversidad, 2012
Se analizó y comparó el espectro trófico de 2 poblaciones de Physalaemus albonotatus que habitan en ecosistemas diferentes: a) un terreno baldío urbano y b) un área protegida del valle aluvial del río Paraná Medio.

Land Use Influences Niche Size and the Assimilation of Resources by Benthic Macroinvertebrates in Tropical Headwater Streams.

PLoS ONE, 2016
It is well recognized that assemblage structure of stream macroinvertebrates changes with alterations in catchment or local land use. Our objective was to understand how the trophic ecology of benthic macroinvertebrate assemblages responds to land use ...

Alike but still different: coexistence of four raptor species explained by breeding habitat segregation

Oikos, EarlyView.
Understanding how species competing for similar resources coexist and influence each other has been, and still is, one of the big questions of community ecology. This question has often been tackled by comparing ecological niches of species pairs, although usually more than just two species compete for the same resources.

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

Ecology of Freshwater Fish
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Solapamiento trófico entre el lobo marino de un pelo Otaria flavescens y la pesquería de arrastre demersal del golfo San Matías, Patagonia, Argentina Trophic overlap between the South American sea lion Otaria flavescens and the demersal trawl fishery in San Matías Gulf, Patagonia, Argentina

Latin American Journal of Aquatic Research, 2011
A nivel internacional, paralelo a la declinación y al colapso de pesquerías de gran escala, surgió un interés creciente por el estudio de las interacciones entre mamíferos marinos y pesquerías. El golfo San Matías (Patagonia, Argentina) es considerado un
