Robert Pal is an Associate Professor and the Director of Restoration at Montana Tech (Department of Biological Sciences). He holds a master’s in agriculture and a Ph.D. in Biology/Plant Ecology. His main research focus has always been the study of the flora and vegetation of disturbed habitats, including agricultural and urban areas. That led him to work on ecological restoration and plant invasions. He was awarded by prestigious research grants such as the Fulbright Research Grant and the Marie Curie Fellowship. Robert is in charge of the Native Plant Restoration Project and is also responsible for the Restoration Certificate at Montana Tech. Besides multiple restoration projects, he is part of several national and international research projects mainly in biological invasions.

Research Interests

As a botanist and community ecologist he is fascinated by one of the fundamental questions in ecology: what interactions determine plant distribution and abundance.

Much of his research has involved large-scale field experiments to address how abiotic and biotic interactions influence community composition and diversity in anthropogenically disturbed habitats. Beside these taxonomically based approaches, he is particularly interested in how environmental conditions and human impacts influence functional organization of weed communities.

Another large part of his research focuses on invasion biology. Here he studies evolutionary changes in invasive plant species (e.g. Solidago gigantea), and novel plant-plant, plant-soil, plant-microorganisms and plant-herbivore interactions arising from new invasions on a transcontinental scale.

Ecology of anthropogenic habitats

  • Restoration Ecology
  • Ecology of arable fields, vineyards, oldfields and energy crops
  • Hyperaccumularion

Biological Invasions

  • Biogeography, phenotypic plasticity
  • Plant-plant, plant-soil, plant-microorganisms and plant-herbivore interactions
  • Competition, diversity loss
  • Biocontrol

Non-Research Academic Interests

Plant taxonomy and syntaxonomy

  • Flora and vegetation survey
  • Habitat and flora mapping
  • Building of phytosociological database
  • Weed communities (arable fields, vineyards and ruderal habitats)
  • Red lists
