First observations of nectar-drinking lizards on the African mainland [PDF]

open access: yesPlant Ecology and Evolution, 2019
Background and aims – Pollination of flowers is performed mainly by insects, but also by vertebrates. In South Africa, beside birds, non-flying mammals contribute to pollination.

On the methodology of feeding ecology in fish [PDF]

open access: yes, 2016
Feeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent ...

Fine‐tuned responses to chemical landscapes: crayfish use predator odors to assess threats based on relative size ratios

open access: yesEcosphere, 2020
The threat‐sensitive predator avoidance hypothesis suggests that prey animals should minimize the costs of antipredator behaviors by only responding to predators that pose a potentially lethal threat.

Visibility and attractiveness of Fritillaria (Liliaceae) flowers to potential pollinators

open access: yesScientific Reports, 2021
Visual floral characters play an important role in shaping plant-pollinator interactions. The genus Fritillaria L. (Liliaceae), comprising approximately 140 species, is described as displaying a remarkable variety of flower colours and sizes.

Melanism and color saturation of butterfly assemblages: A comparison between a tropical rainforest and a xeric white forest

open access: yesFrontiers in Ecology and Evolution, 2023
The study of butterfly coloration has helped to identify the ecological pressures involved in the evolution of animal coloration. However, almost all studies that addressed this issue have focused on species that inhabit more temperate environments ...

Eliciting a predatory response in the eastern corn snake (Pantherophis guttatus) using live and inanimate sensory stimuli: implications for managing invasive populations [PDF]

open access: yes, 2014
North America's Eastern corn snake (Pantherophis guttatus) has been introduced to several islands throughout the Caribbean and Australasia where it poses a significant threat to native wildlife. Invasive snake control programs often involve trapping with

A taste of the deep-sea: The roles of gustatory and tactile searching behaviour in the grenadier fish Coryphaenoides armatus [PDF]

open access: yes, 2007
The deep-sea grenadier fishes (Coryphaenoides spp.) are among the dominant predators and scavengers in the ocean basins that cover much of Earth's surface. Baited camera experiments were used to study the behaviour of these fishes.

The sensory ecology of ocean navigation [PDF]

open access: yesJournal of Experimental Biology, 2008
SUMMARYHow animals guide themselves across vast expanses of open ocean, sometimes to specific geographic areas, has remained an enduring mystery of behavioral biology. In this review we briefly contrast underwater oceanic navigation with terrestrial navigation and summarize the advantages and constraints of different approaches used to analyze animal ...

Opsin expression predicts male nuptial color in threespine stickleback. [PDF]

open access: yes, 2018
Theoretical models of sexual selection suggest that male courtship signals can evolve through the build-up of genetic correlations between the male signal and female preference.

Fruit scent and observer colour vision shape food-selection strategies in wild capuchin monkeys [PDF]

open access: yes, 2019
The senses play critical roles in helping animals evaluate foods, including fruits that can change both in colour and scent during ripening to attract frugivores.
