Ground‐dwelling mammal diversity responds positively to productivity and habitat heterogeneity in a fire‐prone region

Ecosphere, 2020
Environmental heterogeneity has a consistent, positive effect on species diversity globally, principally due to increased niche space in heterogeneous environments.

Selection for cryptic coloration in a visually heterogeneous habitat [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001
We studied selection by predators for cryptic prey coloration in a visually heterogeneous habitat that consists of two microhabitats. It has been suggested that the probability of escaping detection in such habitats might be optimized by maximizing crypsis in one of the microhabitats. However, a recent model indicates that a coloration that compromises

Improving Habitat Heterogeneity on Coastal Defence Structures [PDF]

Coasts, Marine Structures and Breakwaters 2017, 2018
Sea level rise and higher storm frequency is increasing the need for hard coastal defences worldwide. The majority of these structures lack optimal habitats for intertidal species, resulting in low diversity. Here, we evaluate low-cost enhancement techniques which increase habitat heterogeneity and surface texture on different rock types.

The induction of larval resource preference in heterogeneous habitats [PDF]

Ecological Entomology, 2018
1. Animals often have to choose between multiple food sources in their habitat, and these potentially complex decisions have a large impact on their fitness. Among other factors, previous experience with an alternative resource can significantly increase subsequent preference for the resource (‘induction of preference’).

Habitat amount, habitat heterogeneity, and their effects on arthropod species diversity [PDF]

Écoscience, 2013
Abstract: Not all studies have empirically supported the model that predicts a positive relationship between habitat heterogeneity and biodiversity. We hypothesized that these different results stem from the methods used to assess habitat heterogeneity; many studies used variables that are somewhat correlated in nature and measure 2 different features ...

Roles of Clonal Integration in both Heterogeneous and Homogeneous Habitats [PDF]

Frontiers in Plant Science, 2016
Many studies have shown that clonal integration can promote the performance of clonal plants in heterogeneous habitats, but the roles of clonal integration in both heterogeneous and homogeneous habitats were rarely studied simultaneously. Ramet pairs of Alternanthera philoxeroides (Mart.) Griseb were placed in two habitats either heterogeneous or ...

Heterogeneity within and among co-occurring foundation species increases biodiversity

Nature Communications, 2022
Species interactions that can enhance habitat heterogeneity such as facilitation cascades of foundation species have been overlooked in biodiversity models.

Accounting for heterogeneity in false‐positive detection rate in southeastern beach mouse habitat occupancy models

Ecosphere, 2019
Habitat occupancy models, designed to deal with non‐detection of a target species in occupied sites, have been expanded to allow for false‐positive detections when species are mistakenly detected in unoccupied sites.

Immigration rates and species niche characteristics affect the relationship between species richness and habitat heterogeneity in modeled meta-communities [PDF]

PeerJ, 2015
The positive relationship between habitat heterogeneity and species richness is a cornerstone of ecology. Recently, it was suggested that this relationship should be unimodal rather than linear due to a tradeoff between environmental heterogeneity and ...
