Habitat driven responses of reef fish: temporal change, niche partitioning and selection
Shallow water tropical and temperate marine habitats are changing dramatically in response to many stressor-driven effects. The change in turn threatens the associated fish communities relying on their maintenance for habitat provision. At present, a much better understanding of the interaction …

Biotic and abiotic mechanisms shaping multi-species interactions
… multi-species interactions in both tropical and temperate ecosystems. The first three data chapters (Chapters 2–4) were completed within a Neotropical rainforest in Costa Rica and focus on one plant genus, Piper (Piperaceae). The final data chapter (Chapter 5) was conducted within a working …

Experimental litterfall manipulation effects on soil bacterial community structure and soil carbon cycling in a wet tropical forest
… plant-derived carbon (C) inputs to terrestrial ecosystems via changes in litterfall and plant net primary production (NPP). However, the effects of shifting detrital C inputs on belowground microbial community function, C cycling and fluxes remain largely unknown, especially in tropical forest …

Ocean Acidification and Seasonal Temperatures Counter Positive Novel Species Interaction and Warming Effects on Tropicalising Temperate Fish Communities
… conditions or to invade previously inaccessible temperate environments. Climate-driven species redistributions have facilitated range-shifting and local species to interact for available resources. These novel species interactions can modify the pace of species range extensions. In Australia, …

Role of Dissolved Organic Nitrogen in the Soil Nitrogen Cycle of Forest Ecosystems
… be a crucial part of the soil N cycle in forest ecosystems. Despite this, information on its dynamics, sources and fate is still lacking. Especially data from (sub)tropical forest ecosystems are scarce. Therefore, this study investigated (i) the magnitude and drivers of DON fluxes in a …

Consequences of nitrogen fertilization and soil acidification from acid rain on dissolved carbon and nitrogen stability in the unglaciated Appalachian Mountains
… has enriched the earth with N and acidified ecosystems. Acid rain is a primary vector of both N fertilization and acidification, initiating a cascade of consequences that alter biogeochemical cycling and global biological structure and function. Studies on N and acid influences are however …

Assessing the vulnerability of Antarctic marine ecosystems to invasive non-native species
… Antarctica has been poorly connected to nearby temperate ecosystems due to physical and physiological barriers. Yet, Antarctica is experiencing significant environmental change and becoming increasingly exposed to ship-borne human activity that crosses the physical barriers. These factors may …
