The macroecology of plant populations from local to global scales.

New Phytol 2021 Sep 18. Epub 2021 Sep 18.

School of Natural Sciences, Zoology, Trinity College Dublin, Dublin 2, Ireland.

Population ecologists develop theoretical and pragmatic knowledge of how and why populations change or remain stable, how life histories evolve, and devise management strategies for populations of concern. However, forecasting the effects of global change or recommending management strategies is often urgent, requiring ecologists to work without detailed local evidence while using data and models from outside the focal location or species. Here we explore how the comparative ecology of populations, population macroecology, can be used to develop generalisations within and between species across different scales, using available demographic, environmental, life-history, occurrence, and trait data.

Dose-dependent effect of mesenchymal stromal cells co-grafted with dopaminergic neurons in a Parkinson's disease rat model.

J Cell Mol Med 2021 Sep 18. Epub 2021 Sep 18.

Cellular and Molecular Neurobiology of Parkinson's disease, Research Center for Molecular Medicine and Chronic diseases (CIMUS), IDIS, University of Santiago de Compostela, Santiago de Compostela, Spain.

A major limiting factor for cell therapy in Parkinson's disease is the poor survival and reinnervation capacity of grafted dopaminergic neurons, independently of the cell source. Mesenchymal stromal cells (MSCs) have high capability to regulate the local environment through the release of trophic, antiapoptotic and immunomodulatory factors. In this work, we investigated whether co-grafting of MSCs could improve the survival and reinnervation ability of dopaminergic precursors transplanted in animal models of Parkinson's disease.
