LifeCLEF 2016: Multimedia Life Species Identification Challenges

The LifeCLEF lab proposes to evaluate 3 challenges related to multimedia information retrieval and fine-grained classification problems in 3 domains based on large volumes of real-world data and the measured challenges are defined in collaboration with biologists and environmental stakeholders to reflect realistic usage scenarios.

Do differences in food web structure between organic and conventional farms affect the ecosystem service of pest control?

A food-web approach to analyse the community structure and function at the whole-farm scale showed that organic farms have significantly more species at three trophic levels (plant, herbivore and parasitoid) and significantly different network structure.

On optimal decision-making in brains and social insect colonies

It is shown that social insect colonies may also be able to achieve statistically optimal collective decision-making in a very similar way to primate brains, via direct competition between evidence-accumulating populations.

Lost in Transition: Start-Up of Glycolysis Yields Subpopulations of Nongrowing Cells

How cell fate can be determined by glycolytic dynamics combined with cell heterogeneity purely at the metabolic level is revealed, extending fundamental knowledge of this central pathway that is dysfunctional in diseases such as diabetes and cancer.

Species interactions and the structure of complex communication networks

The view that multispecies choruses are structured by temporal, spatial, or acoustic partitioning is challenged and it is suggested that social communication between competing species can fundamentally organize signaling assemblages, leading to the opposite pattern of clustering in signals and signaling behavior.

Spectral Overlap in Songs and Temporal Avoidance in a Peruvian Bird Assemblage

Sound is the preferred mode of communication for many animals. Insects, frogs, birds and mammals are all well known for their acoustic signals through which they attract mates or repel rivals (Rogers…

Evolution of Defence Portfolios in Exploiter–Victim Systems

The circumstances under which defence strategies might be expected to evolve are investigated, and it is suggested that the answers lie in strategy-blocking, where one strategy prevents the appearance of another (the blocked strategy) that would be adaptive in its absence.

Overview of BirdCLEF 2021: Bird call identification in soundscape recordings

The 2021 BirdCLEF challenge focused on developing and assessing automated analysis frameworks for avian vocalizations in continuous soundscape data and the primary task was to detect and identify all bird calls within the hidden test dataset.
