Spatial ecology of territorial populations [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Many ecosystems, from vegetation to biofilms, are composed of territorial populations that compete for both nutrients and physical space. What are the implications of such spatial organization for biodiversity? To address this question, we developed and analyzed a model of territorial resource competition.

Ontogeny of color development in two green–brown polymorphic grasshopper species

open access: yesEcology and Evolution, 2023
Many insects, including several orthopterans, undergo dramatic changes in body coloration during ontogeny. This variation is particularly intriguing in gomphocerine grasshoppers, where the green and brown morphs appear to be genetically determined ...

Mind the Wound!—Fruit Injury Ranks Higher than, and Interacts with, Heterospecific Cues for Drosophila suzukii Oviposition

open access: yesInsects, 2021
Drosophila suzukii is a globally distributed insect that infests many economically important fruit varieties by ovipositing into ripening fruits.

Balancing Life History Investment Decisions in Founding Ant Queens

open access: yesFrontiers in Ecology and Evolution, 2020
Reproduction is a very critical step in the life of an organism. Females must balance their investment in different life-history traits while reproducing.

The green-brown polymorphism of the club-legged grasshopper Gomphocerus sibiricus is heritable and appears genetically simple

open access: yesBMC Evolutionary Biology, 2020
Background Local coexistence of distinct, genetically determined color morphs can be unstable and transitional. Stable, long-term coexistence requires some form of balancing selection to protect morphs from getting lost by directional selection or ...

Making virtual species less virtual by reverse engineering of spatiotemporal ecological models

open access: yesMethods in Ecology and Evolution, 2023
The virtual species (VS) and virtual ecologist (VE) approaches are useful tools that allow testing different methodological aspects of species distribution modelling.

Are there ecological limits to population? [PDF]

open access: yesProceedings of the National Academy of Sciences, 1993
Policy on population and environment in the United States and abroad has been vacillating, unsure of its course; it would be more decisive if the several disciplines could agree on the nature of the problems and their urgency. The two disciplines principally concerned are biology and economics, and the contribution of this paper is to identify eight of

Competition over guarding in the Arabian babbler (Turdoides squamiceps), a cooperative breeder [version 1; referees: 1 approved, 2 approved with reservations]

open access: yesF1000Research, 2015
Observations on 12 groups comprised of two adult males and one adult female (some included one or two fledglings), tame, individually marked, Arabian babblers (Turdoides squamiceps) in the rift valley in Israel revealed that the babblers compete to guard.
