Acta Limnologica BrasiliensiaAim Studies of natural variations in fish diet allow, in turn, a better understanding of environmental changes along the hydrological cycle that can affect resources and, hence, biodiversity conservation.

Fins are relevant non-lethal surrogates for muscle to measure stable isotopes in amphibians
Knowledge and Management of Aquatic Ecosystems, 2019 Stable isotope analyses (SIA) are now widely used in ecology research to quantify the trophic implications of a large range of ecological processes.

Studying interspecific population synchrony: current status and future perspectives
Ecography, EarlyView.Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization
Ecography, EarlyView.Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Ecography, EarlyView.Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Drivers and food web effects of Gonyostomum semen blooms [PDF]
, 2013 The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

Biodiversity in model ecosystems, II: Species assembly and food web structure
, 2005 This is the second of two papers dedicated to the relationship between population models of competition and biodiversity. Here we consider species assembly models where the population dynamics is kept far from fixed points through the continuous ...

Environmental and geomorphological drivers of frog diversity on islands worldwide
Ecography, EarlyView.Island biogeography models primarily rely on island physical features and isolation to explain their biodiversity patterns. While newer models have incorporated functional traits to understand plant distribution, few empirical studies have tried to disentangle geometric constraints from niche‐based processes to predict multiple diversity facets of ...

Ökologische und genetische Differenzierung von Daphnia-galeata-Populationen in Europa [PDF]
, 2005 Here I analyse 23 populations of D. galeata, a large-lake cladoceran, distributed mainly across the Palaearctic. I detected high levels of clonal diversity and population differentiation using variation at six microsatellite loci across Europe.
