Trophic levels of fish species of commercial importance in the Colombian Caribbean

Revista de Biología Tropical, 2011
Ecological studies on commercial important fish species are of great value to support resource management issues. This study calculated trophic levels of those Colombian Caribbean fish species whose diet has been locally described.

Dieta, selectividad y solapamiento trófico entre las tallas del pez blanco Menidia humboldtiana (Atheriniformes: Atherinopsidae) en el embalse Tiacaque, México

Revista de Biología Tropical, 2013
Menidia humboldtiana es una especie nativa muy apreciada por su delicado sabor. Se determinó el espectro trófico, selectividad y solapamiento trófico de ésta, durante 1995 (épocas del año), se obtuvieron muestras de zooplancton e identificaron a nivel ...

Reconsidering the role of introduced species in the climate-affected and highly invaded eastern Mediterranean. [PDF]

Conserv Biol
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Record phenological responses to climate change in three sympatric penguin species. [PDF]

J Anim Ecol
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Across the edge: Spatial segregation drives community structure in tri-trophic multilayer networks at a forest-grassland edge. [PDF]

J Anim Ecol
This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Effects of landscape fragmentation on floodplain fishes as revealed by species-habitat networks. [PDF]

Conserv Biol
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Análisis trófico de tres especies de Marilia (Tri-choptera: Odontoceridae) del neotrópico [PDF]

Revista de Biología Tropical, 2014
La ecología trófica de insectos acuáticos ha sido desarrollada en zonas templadas. Sin embargo, la asignación de un taxón a un grupo trófico no representa necesariamente el mismo en otras regiones.
