Structure and composition of Androstachys johnsonii woodland across various strata in Gonarezhou National Park, southeast Zimbabwe [PDF]
, 2011 A study on the structure and composition of Androstachys johnsonii Prain (Euphorbiaceae) woodland across three strata was conducted in Gonarezhou National Park (GNP), southeast Zimbabwe.

Do trophic subsidies affect the outcome of introductions of a non-native freshwater fish? [PDF]
, 2013 Understanding how environmental variables and human disturbances influence the outcomes of introductions of non-native freshwater fish is integral to their risk management. This can be complex in freshwater ecosystems that receive subsidies that increase

The feasibility principle in community ecology
Oikos, EarlyView.The structure and function of ecological communities emerge from interactions among populations within specific environmental contexts. Yet we still lack general principles that explain how communities assemble, which patterns we should expect, and when transitions occur across diverse settings.

Invasibility of neutral communities
Basic and Applied Ecology, 2009 Abstract Comparative data in invasion ecology show that (i) disturbance enhances community invasibility, (ii) there is a positive relationship between residence time of an invader and its success, (iii) there are broadly constant proportions of newly arrived species to those that become established and dominant (“tens rule”), and (iv) invasive ...

Seedling Emergence from Seed Banks in Ludwigia hexapetala-Invaded Wetlands: Implications for Restoration [PDF]
, 2019 Soil seed banks play a critical role in the maintenance of wetland plant communities and contribute to revegetation following disturbances. Analysis of the seed bank can therefore inform restoration planning and management.

Coexistence, crossover and extirpation in coalescent communities and ecotones
Oikos, EarlyView.When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Invasive plant removal: assessing community impact and recovery from invasion [PDF]
Journal of Applied Ecology, 2017 Summary Invasive species spread on natural ecosystems is one of the most important causes of biodiversity loss. To disentangle the invasive plant impact on communities it is essential to combine experimental and observation approaches, which enable the correct interpretations of results and lead to the right decisions for management. We examined the

The influence of vegetation structure and composition on invasibility by Pinus radiata in the Blue Mountains, NSW [PDF]
, 2013 The exotic tree species Pinus radiata D. Don (in the family Pinaceae) has successfully spread from commercial plantations into adjacent vegetation in southeastern Australia.

A citation-based map of concepts in invasion biology [PDF]
, 2019 Invasion biology has been quickly expanding in the last decades so that it is now metaphorically flooded with publications, concepts, and hypotheses. Among experts, there is no clear consensus about the relationships between invasion concepts, and almost

adapt3: Adaptive dynamics and community projection in the R programming language
Methods in Ecology and Evolution, EarlyView.Abstract Ecologists typically use matrix projection to understand population dynamics. Recently, they have applied matrix projection to analyse communities and evolutionary dynamics. Particularly, matrix community models (MCMs) provide a reductionist, demographic approach to the study of ecological interactions, while adaptive dynamics assess the ...
