The Collective Power of Bacteria as a Blueprint for Emergent Intelligence

Advanced Intelligent Systems, EarlyView.
Small cells, powerful collectives. Bacteria demonstrate how sophisticated behaviors can emerge from many simple individuals working together. We explore the remarkable world of bacterial communities and the mechanisms that underpin their complex emergent behaviors, enabling impressive adaptability, robustness, and responsiveness to changing ...

Internal state dynamics shape brainwide activity and foraging behaviour

, 2020
The brain has persistent internal states that can modulate every aspect of an animal’s mental experience(1–4). In complex tasks such as foraging, internal state is dynamic(5–8). C. elegans alternate between local search and global dispersal5. Rodents and

Foraging in a dynamic environment: Response of four sympatric sub‐Antarctic albatross species to interannual environmental variability

Ecology and Evolution, 2020
Seasonal and annual climate variations are linked to fluctuations in the abundance and distribution of resources, posing a significant challenge to animals that need to adjust their foraging behavior accordingly.

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Dinner Date: Opposite-Sex Pairs of Fruit Bats (Rousettus aegyptiacus) Forage More than Same-Sex Pairs

Biology
Social animals have unique foraging behaviors that consider not only the needs of the individual, but also the needs of the group. When social animals forage together, there is a greater sense of perceived safety, leading to less vigilance and more ...

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

The Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Sexual castes of Trachymyrmex fuscus (Formicidae: Attini) performing worker tasks

Ciência Rural, 2015
:The main of this research was to report an atypical foraging behavior in a colony of Trachymyrmex fuscus, situated in "Cerrado" (savanna ecoregion of Goiás, Brazil). The colony foraging activity was performed only by sexual caste.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.
