Perch shape and material affect perch use and health parameters of laying hens during the rearing and laying phase

open access: yesJournal of Applied Poultry Research
SUMMARY: Perches are an important resource for laying hens and differ in characteristics like shape, material and diameter. In this study, different perches were tested in regard to animal welfare, focusing specifically on the behavior and health of ...

The Climbing Perch [PDF]

open access: yesNature, 1879
THE aquarium of the Zoological Society's Gardens in Regent's Park has lately received a contribution of five specimens of the “Climbing Perch” (Anabas scandens). They were very kindly obtained for me by my friend, Mr. A. Ferguson, of Colombo, Ceylon, and were brought home in excellent condition by my brother, Mr. A. F. Dobson. Mr.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

open access: yesOikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

open access: yesOikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

open access: yesPeople and Nature, EarlyView.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.

The relationship between perch type and aggressive behavior in the lizard Norops polylepis (Squamata: Dactyloidae)

open access: yesPhyllomedusa: Journal of Herpetology, 2015
The intensity of aggression against intruders by owners of a territory has been related to the type of resources available to an individual within its territory.

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...
