Predominantly Terrestrial Foraging and Reproductive Gains From a High Trophic Level Diet in Roof‐Nesting Herring Gulls (Larus argentatus) [PDF]
Wild animal species often use human‐modified environments for foraging and reproduction, but this may require dietary diversification with fitness consequences.

Trophic state assessment of optically diverse lakes using Sentinel-3-derived trophic level index
An accurate estimation of trophic state of lakes with satellite remote sensing is a challenge due to the optical complexity and variability associated with inland waters. Match-up data from 393 sampling stations that has concurrent Sentinel-3 OLCI images

Plant genetic diversity affects multiple trophic levels and trophic interactions [PDF]
Abstract Intraspecific genetic diversity is an important component of biodiversity. A substantial body of evidence has demonstrated positive effects of plant genetic diversity on plant performance. However, it has remained unclear whether plant genetic diversity generally increases plant performance by reducing the pressure of plant ...

How directed is a directed network?
The trophic levels of nodes in directed networks can reveal their functional properties. Moreover, the trophic coherence of a network, defined in terms of trophic levels, is related to properties such as cycle structure, stability and percolation.

Niche partitioning and the role of intraspecific niche variation in structuring a guild of generalist anurans [PDF]
Intra-population niche differences in generalist foragers have captured the interest of ecologists, because such individuality can have important ecological and evolutionary implications. Few researchers have investigated how these differences affect the
