Patterns of aquatic macrophytes in the boreal region: implications for spatial scale issues and ecological assessment

Autor: Alahuhta, J. (Janne)

Eutrophication and global warming are increasingly causing deterioration of aquatic ecosystems, and boreal freshwaters are especially vulnerable to these changes. Anthropogenic pressures and landscape characteristics influencing the functioning and s

Deciphering land-use influences on boreal lakes to guide landscape planning

Autor: Heino, J. (Jani), Toivanen, M. (Maija), Alahuhta, J. (Janne)

1. Changes in natural land cover have been pronounced in the last 12,000 years, and land use has intensified in the last century owing to anthropogenic pressures on landscapes. This trend has led to concomitant changes in the abiotic templates and bi

Isoëtes sabatina (Isoëtaceae, Lycopodiopsida):taxonomic distinctness and preliminary ecological insights

Autor: Bolpagni, R. (Rossano), Magrini, S. (Sara), Coppi, A. (Andrea), Troìa, A. (Angelo), Alahuhta, J. (Janne), Mjelde, M. (Marit), Azzella, M. M. (Mattia M.)

Isoëtes sabatina is the rarest aquatic quillwort in Europe. Although recently found (2013) in Lake Bracciano (central Italy), the species is just one step away from extinction with an estimated population not exceeding 400 individuals and a spatial

Same species, same habitat preferences?:the distribution of aquatic plants is not explained by the same predictors in lakes and streams

Autor: Gillard, M. B. (Morgane B.), Aroviita, J. (Jukka), Alahuhta, J. (Janne)

1. Studying the geographical distribution of species can reveal conditions and processes that may drive species presence and abundance. Organism distribution has frequently been explained by climate, but the relative role of local environmental predi

Knitting patterns of biodiversity, range size and body size in aquatic beetle faunas:significant relationships but slightly divergent drivers

Autor: Heino, J. (Jani), Alahuhta, J. (Janne)

1. Ecogeographical rules refer to recurring patterns in nature, including the latitudinal diversity gradient (LDG), Rapoport’s rule and Bergmann’s rule, amongst others. In the present study, the existence of these rules was examined for diving be

Macroecology of ground beetles:species richness, range size and body size show different geographical patterns across a climatically heterogeneous area

Autor: Heino, J. (Jani), Alahuhta, J. (Janne), Fattorini, S. (Simone)

Aim: Ecogeographical patterns have been widely studied in endothermic vertebrates, but relatively few studies have simultaneously examined patterns and causes of gradients in species richness, range size and body size in ectothermic insects. We exami

Predicting beta diversity of terrestrial and aquatic beetles using ecogeographical variables:insights from the replacement and richness difference components

Autor: Heino, J. (Jani), Alahuhta, J. (Janne), Fattorini, S. (Simone), Schmera, D. (Dénes)

Aim: We examined the responses of the beta diversity of aquatic and terrestrial beetles to ecogeographical variables, including climate, land cover and land use, across Northern Europe. Location: Northern Europe (Denmark, Sweden, Norway and Finland).

Understanding environmental change through the lens of trait-based, functional, and phylogenetic biodiversity in freshwater ecosystems

Autor: Alahuhta, J. (Janne), Erős, T. (Tibor), Kärnä, O.-M. (Olli-Matti), Soininen, J. (Janne), Wang, J. (Jianjung), Heino, J. (Jani)

In the era of the Anthropocene, environmental change is accelerating biodiversity loss across ecosystems on Earth, among which freshwaters are likely the most threatened. Different biodiversity facets in the freshwater realm suffer from various envir
