Nocturnal pollination of Parkia velutina by Megalopta bees in Amazonia and its possible significance in the evolution of chiropterophily. [PDF]

open access: yes, 2000
Canopy observations of the rain forest tree Parkia velutina (Leguminosae: Mimosoideae) in Amazonian Brazil indicate that it is pollinated by night-flying bees.

Portable thermal scanners to detect and monitor small endotherms: A comparative assessment of available equipment to guide practitioners

open access: yesEcology and Evolution, 2023
Detection is essential to studying and monitoring wild animals; however, detection is challenging for small endotherms that are nocturnal or best detected at night.

Composite hodographs and inertial oscillations in the nocturnal boundary layer [PDF]

open access: yes, 2011
In this work the dynamic behaviour of the wind in the nocturnal boundary layer is studied, with a particular focus on systematic behaviour of the near-surface wind.

Cabinet of Curiosities: Venom Systems and Their Ecological Function in Mammals, with a Focus on Primates

open access: yesToxins, 2015
Venom delivery systems (VDS) are common in the animal kingdom, but rare amongst mammals. New definitions of venom allow us to reconsider its diversity amongst mammals by reviewing the VDS of Chiroptera, Eulipotyphla, Monotremata, and Primates. All orders

The development of an unsupervised hierarchical clustering analysis of dual‐polarization weather surveillance radar observations to assess nocturnal insect abundance and diversity

open access: yesRemote Sensing in Ecology and Conservation, 2022
Contemporary analyses of insect population trends are based, for the most part, on a large body of heterogeneous and short‐term datasets of diurnal species that are representative of limited spatial domains.

Behavioral and Thermoregulatory Responses to Changes in Ambient Temperature and Wheel Running Availability in Octodon degus

open access: yesFrontiers in Integrative Neuroscience, 2021
Octodon degus is primarily a diurnal species, however, in laboratory conditions, it can switch from diurnal to nocturnal in response to wheel running availability.

Venom in Furs: Facial Masks as Aposematic Signals in a Venomous Mammal

open access: yesToxins, 2019
The function of colouration in animals includes concealment, communication and signaling, such as the use of aposematism as a warning signal. Aposematism is unusual in mammals, and exceptions help us to understand its ecology and evolution.
