A natural experiment identifies an impending ecological trap for a neotropical amphibian in response to extreme weather events

open access: yesEcology and Evolution, 2022
Extreme weather events are predicted to increase as a result of climate change, yet amphibian responses to extreme disturbance events remain understudied, especially in the Neotropics.

Exploited resources of major perches in India [PDF]

open access: yes, 2000
The present paper reviews the studies on the exploited resources of mqjor perches from, the Indian seas. Major perches consist of fairly large sized fishes belonging to families Serranidae, Lutjanidae and Lethrinidae, popularly known as rock cods ...

Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

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 ...

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.

Gay in the Sasanian period: some preliminary notes on its circular urban plan [PDF]

open access: yes, 2018
This paper examines the Sasanian allegedly circular city of Gay, in the region of Isfahan. Material traces of the city have unfortunately been lost so we are forced to rely on Islamic literary sources alone.

Interaction of Seed Dispersal and Environmental Filtering Affects Woody Encroachment Patterns in Coastal Grassland [PDF]

open access: yes, 2019
Encroachment of woody plants into grasslands has occurred worldwide and includes coastal ecosystems. This conversion process is mediated by seed dispersal patterns, environmental filtering, and biotic interactions.

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Tree planting, natural colonisation, hybrid approaches: Land manager decisions explored

open access: yesPeople and Nature, EarlyView.
Abstract There is a global drive to protect biodiversity and help combat climate change. In the UK, this is expressed in a number of policy initiatives and tools that include increasing tree cover as an important nature‐based solution to achieving national policy targets.
