Habitat complexity facilitates coexistence in a tropical ant community
Oecologia, 2006The role of habitat complexity in the coexistence of ant species is poorly understood. Here, we examine the influence of habitat complexity on coexistence patterns in ant communities of the remote Pacific atoll of Tokelau. The invasive yellow crazy ant, Anoplolepis gracilipes (Smith), exists in high densities on Tokelau, but still coexists with up to ...

Habitat complexity, environmental change and personality: A tropical perspective
Behavioural Processes, 2015Tropical rainforests are species-rich, complex ecosystems. They are increasingly being negatively affected by anthropogenic activity, which is rapidly and unpredictably altering their structure and complexity. These changes in habitat state may expose tropical animals to novel and unpredictable conditions, potentially increasing their extinction risk ...

Habitat Selection in Geographically Complex Landscapes
1999The practice of landscape ecology is generally one that attempts to understand how patterns of abundances may interact with the physiognomic and compositional characteristics of landscapes (Dunning et al. 1992, Morris and Brown 1992). However, the goal is to understand why populations, enumerated across large spatial scales, frequently are not ...

Priority effects and habitat complexity affect the strength of competition
Oecologia, 2010Both habitat complexity and priority effects can influence the strength of competitive interactions; however, the independent and synergistic effects of these processes are not well understood. In Moorea, French Polynesia, we conducted a factorial field experiment to quantify the independent and combined effects of priority effects and habitat ...

Habitat complexity mediates the predator–prey space race
Ecology, 2019AbstractThe spatial relationship between predator and prey is often conceptualized as a behavioral response race, in which prey avoid predators while predators track prey. Limiting habitat types can create spatial anchors for prey or predators, influencing the likelihood that the predator or prey response will dominate.

Exploitation ecosystems in heterogeneous habitat complexes
Evolutionary Ecology, 1990When the model of exploitation ecosystems by Oksanenet al. (1981) is re-analysed, using similar consumer-victim differential equations, but allowing dispersal between habitats differing in primary productivity, the relation between trophic dynamics and primary productivity turns out to be strongly dependent on the abundance relationships between ...

Ethology, 2019
AbstractHabitat structure can impede visibility and movement, resulting in lower resource monopolization and aggression. Consequently, dominant individuals may prefer open habitats to maximize resource gain, or complex habitats to minimize predation risk.

Wetlands, 1996
The crayfishProcambarus alleni is abundant in densely vegetated habitats within the freshwater wetland mosaics of central and southern Florida. We performed laboratory experiments to determine whether habitat preference and/or predation could account for habitat use by this species.

Fish feeding in changing habitats: effects of invasive macrophyte control and habitat complexity
Ecology of Freshwater Fish, 2009Abstract – Many freshwater lakes have been invaded by non‐native aquatic plants. Although managing the invasions is necessary to restore native macrophytes, little is known about the effects of invasive macrophyte eradication on fish foraging. This study was designed to determine whether fish feeding was affected by large‐scale changes in plant ...

The effect of habitat complexity on bacterial competition
The way microbes interact in nature can vary widely depending on the spatial characteristics they are located in. This aspect of the microbial environment can determine whether processes such as organic matter turnover, community dynamics, or microbial speciation, among others, occur and their impact on soil functions.
