On traits matching and the modular organization of food web and occurrence networks

Journal of Animal Ecology, EarlyView.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Ichthyofauna of piedmont and savannah environments in the Casanare River drainage, Orinoco Basin, Colombia

Biota Colombiana, 2018
Currently, only 20 fish species have been recorded from the Casanare River, which is one of the main tributaries of the Meta River drainage. To characterize the fish assemblages of this river, samplings were carried out at 35 collecting stations in low ...

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

A combinatorial approach to angiosperm pollen morphology [PDF]

, 2016
Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Population Genetic Structure and Species Delimitation of a Widespread, Neotropical Dwarf Gecko [PDF]

, 2019
Amazonia harbors the greatest biological diversity on Earth. One trend that spans Amazonian taxa is that most taxonomic groups either exhibit broad geographic ranges or small restricted ranges.

Early ontogeny and swimming behavior of larvae of the neotropical fish Prochilodus costatus Valenciennes 1850 and Prochilodus argenteus Spix & Agassiz 1829 (Characiformes: Prochilodontidae) [PDF]

, 2016
Early development of fish larvae is a highly dynamic process and its study may provide important information about ontogenetic development, bioenergetic growth, behaviour, taxonomic characteristics for identification in natural environments ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
