Mammals adjust diel activity across gradients of urbanization. [PDF]

Elife, 2022
Time is a fundamental component of ecological processes. How animal behavior changes over time has been explored through well-known ecological theories like niche partitioning and predator–prey dynamics. Yet, changes in animal behavior within the shorter 24-hr light–dark cycle have largely gone unstudied.

Raccoon Dogs Adjust Diel Visitation at Scent Marking Latrines to Reduce Human Disturbance in Urban Areas [PDF]

Ecology and Evolution
Human activity and development have a variety of effects on wildlife behavior, often prompting urban wildlife to adopt behavioral strategies—including spatiotemporal activity adjustments—that facilitate persistence in human‐dominated environments.

Diel Versus Seasonal Butterfly Community Partitioning in a Hyperdiverse Tropical Rainforest [PDF]

Insects
Ecological theory suggests that interspecific interactions and environmental heterogeneity promote temporal niche partitioning, whereby species segregate their activity along diel and seasonal axes.

Consistent diel activity patterns of forest mammals among tropical regions. [PDF]

Nat Commun, 2022
Abstract An animal’s daily use of time (their “diel activity”) reflects their adaptations, requirements, and interactions, yet we know little about the underlying processes governing diel activity within and among communities. Here we examine whether community-level activity patterns differ among biogeographic regions, and explore the

Dual Activation of Aromatic Diels–Alder Reactions [PDF]

Chemistry – A European Journal, 2019
AbstractThe unusually fast Diels–Alder reactions of [5]cyclophanes were analyzed by DFT at the BLYP‐D3(BJ)/TZ2P level of theory. The computations were guided by an integrated activation‐strain and Kohn–Sham molecular orbital analysis. It is revealed why both [5]metacyclophane and [5]paracyclophane exhibit a significant rate enhancement compared to ...

Seabird Migration Strategies: Flight Budgets, Diel Activity Patterns, and Lunar Influence [PDF]

Frontiers in Marine Science, 2021
Every year, billions of birds undertake extensive migrations between breeding and non-breeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in daily activity patterns and the influence of extrinsic factors (e.g., environmental conditions, moonlight) have received much more ...

Soundscapes show disruption across the diel cycle in human modified tropical landscapes

Ecological Indicators, 2022
1. Fluctuations in the diel cycle, especially when compared across different land-use types, can reveal key changes in acoustic activity and the biological community.

Rain reverses diel activity rhythms in an estuarine teleost [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2013
Activity rhythms are ubiquitous in nature, and generally synchronized with the day–night cycle. Several taxa have been shown to switch between nocturnal and diurnal activity in response to environmental variability, and these relatively uncommon switches provide a basis for greater understanding of the mechanisms and adaptive significance ...

Variation in Diel Activity of Ground Beetles (Coleoptera: Carabidae) Associated With a Soybean Field and Coal Mine Remnant [PDF]

, 2018
Diel activities of carabids (Coleoptera: Carabidae) associated with a coal mine remnant and surrounding soybean field were studied in west-central Illinois from June through October 2002.

Diel predator activity drives a dynamic landscape of fear [PDF]

Ecological Monographs, 2017
AbstractA ‘landscape of fear’ (LOF) is a map that describes continuous spatial variation in an animal’s perception of predation risk. The relief on this map reflects, for example, places that an animal avoids to minimize risk. Although the LOF concept is a potential unifying theme in ecology that is often invoked to explain the ecological and ...
