“…Kaufmann 2001described the colonisation pattern as deterministic and directional, but more recently, Vater and Matthews (2015) proposed two different modes of colonisation: the 'addition and persistence' and 'replacement-change'. The former was observed in Northern-Europe, in the Andes (Vater & Matthews 2015, Moret et al 2020) and on peripheral mountain groups of the Southern Alps (Tampucci et al 2015). It consists in the persistence of pioneer species (i.e.…”

“…Since then, several papers were published on carabid beetle succession along European glacier forelands (e.g. Gobbi et al 2007, Schlegel et al 2012 in the Alps, Vater & Matthews 2015, Hågvar et al 2017, and more recently on an equatorial glacier foreland (Moret et al 2020). Time since deglaciation seems to be the primary variable affecting carabid beetle species richness, taxonomic and functional diversity patterns in space and time.…”

Aim of this paper is to provide the first comprehensive synthesis about ground beetle (Coleoptera: Carabidae) distribution in high altitude habitats. Specifically, the attention is focused on the species assemblages living on the most common ice-related mountain landforms (glaciers, debris-covered glaciers, glacier forelands and rock glaciers) and the challenges, threats and opportunities carabids living in these habitats have to face concerning the ongoing climate warming. The suggested role of the ice-related alpine landforms, as present climatic refugia for cold-adapted ground beetles, is discussed. Finally, the needs to develop a large-scale High-alpine Biodiversity Monitoring Program to describe how the current climate change is shaping the distribution of high altitude specialists is highlighted.

“…in Europe; Dyscolus spp. on the Andes [37]) from the sites deglaciated few years ago (early successional stages) to sites deglaciated more than 100 years ago (late successional stages)-in this case, there is no species turnover along the chronosequence of glacier retreat. The "replacement-change" model, mainly observed on the Alps (e.g., [17,36]), consists in a group of initial colonizers (the pioneer community) progressively replaced over time by one or more other species assemblages; thus, in this case, there is a clear species turnover.…”

“…The colonization of a glacier foreland by ground beetles is triggered mainly by time since glaciation, distance to glacier and vegetation cover, as highlighted by studies carried out in Northern Europe (e.g., [30][31][32]), Alps (e.g., [27,[33][34][35][36]) and more recently Andes [37]. The colonization of a glacier foreland by ground beetles can follow two different models: the "addition and persistence" and "replacement-change" models [31].…”

At first glance, the ground surrounding the glacier front and the streams originated by melting glaciers seem to be too extreme to host life forms. They are instead ecosystems, colonized by bacteria, fungi, algae, mosses, plants and animals (called the "glacial biodiversity"). The best adapted animals to colonize glacier surface, the recently deglaciated terrains and glacial streams are insects, specifically the ground beetles (carabids) and the non-biting midges (chironomids). This chapter aims to overview the species colonizing these habitats, their adaptation strategies to face natural cold and anthropogenic heat and the extinction threats of glacial retreat and pollution by emerging contaminants. Notes on their role in the glacial-ecosystem functioning and related ecosystem services are also given.

We applied a multi-taxa approach integrating the co-occurrence of plants, ground beetles, spiders and springtails with soil parameters (temperatures and chemical characteristics) in order to describe the primary succession along two glacier forelands in the Maritime Alps (Italy), a hotspot of Mediterranean biodiversity. We compared these successions to those from Central Alps: Maritime glacier forelands markedly differ for their higher values of species richness and species turnover. Contrary to our expectation, Maritime glacier forelands follow a ‘replacement change model’, like continental succession of Inner Alps and differently from other peripheral successions. We propose that the temperatures along these Mediterranean glacier forelands are warmer than those along other Alpine glacier forelands, which promote the faster species turnover. Furthermore, we found that early and mid successional stages of the investigated glaciers are richer in cold-adapted and endemic species than the later ones: we confirmed that the ‘replacement change’ model disadvantages pioneer, cold-adapted species. Given the overall correspondence among cold-adapted and endemic species, the most threatened in this climate phase, our results raise new concerns about the extinction risk of these species. We also describe supraglacial habitat of Maritime glaciers demonstrating that supraglacial debris represents an environment decoupled from the regional climate and may have an important role as refugium for coldadapted and hygrophilous plant and animal species, whose survival can be threatened by climate change and by a rapid ecological succession in the adjacent forelands.
