“…TreMs are not the "silver bullet" indicator to quantify and predict species richness. Nevertheless, through their relationships with species from many taxonomic groups [41,42], they have the potential to indicate habitat quality for a large section of forest-dwelling species, often better than other established indicators such as single focal species or red-list species [24,27]. Combined with other types of direct or indirect (e.g., structural) biodiversity indicators, standard TreM inventories have the potential to capture a large proportion of forest biodiversity.…”

“…Various attempts have been made to develop indicators of forest biodiversity for large gradients of spatial and temporal scales. These range from the use of single keystone or flagship species to faunal [27] or structural surrogates (e.g., deadwood [22,28]). An indicator is a measure of a quantity or a phenomenon that is easier to assess than its target (viz., the indicandum).…”

Purpose of the Review The concept of tree-related microhabitats (TreMs) is an approach to assess and manage multi-taxon species richness in forest ecosystems. Owing to their provision of special habitat features, TreMs are of special interest as a surrogate biodiversity indicator. In particular, in retention forestry, TreMs have gained attention over the past decade as a selection criterion for retained structural elements such as habitat trees. This review seeks to (a) address the suitability of TreMs as biodiversity indicator in the context of retention forestry, (b) summarize drivers of TreM occurrence and the status quo of the implementation of TreM-based retention concepts in forest management, and (c) discuss current and future challenges to the use of TreMs as biodiversity indicator. Recent Findings The TreM concept originated in Europe where it is now increasingly implemented. Most studies of the quantity, quality, and diversity of TreMs are focused on tree species from this region, although it is increasingly applied in other contexts. In addition to tree species, tree dimensions and live status have been identified as the main drivers of TreM occurrence. One major remaining research challenge is to verify relationships between the occurrence and abundance of forest-dwelling species from different taxonomic groups and TreMs to improve the evidence basis of this concept and thus increase its integration in forest conservation approaches. Summary TreMs are not the “silver bullet” indicator to quantify biodiversity of forest dwelling species, but they provide an important tool for forest managers to guide the selection of habitat trees for the conservation of the associated biodiversity.

“…This approach relies on expert opinion to validate datasets, methods, and results. Although the use of expert opinion in the selection of umbrella and other surrogate species can be valuable, particularly given limited information and data gaps (Beazley, Baldwin & Reining, 2010; Moody & Grand, 2012), it can also be prone to taxonomic and regional biases and has been criticized for being irreproducible (Burgman et al, 2011; Magg, Ballenthien & Braunisch, 2019). Despite this, conservation management decisions are typically informed to some extent by expert knowledge (Martin et al, 2012).…”

“…Despite these challenges, some studies indicate that the selection of a suite of umbrella species or taxa, rather than a single species, may be particularly effective as a conservation strategy, especially at large spatial scales (Sanderson et al, 2002; Roberge & Angelstam, 2004; Khosravi & Hemami, 2019; Magg, Ballenthien & Braunisch, 2019). Criteria used to select umbrella species have included spatial area requirements, ecological function, and vulnerability (e.g.…”

1. Where freshwater species populations are in decline, conservation management requires rapid, cost-effective approaches to develop recommendations, particularly at broad geographical scales or where species-specific information is lacking. The umbrella species approach, typically applied to terrestrial taxa, is one potentially useful option to inform large-scale freshwater management efforts.2. A quantitative, integrated approach is proposed for selecting suites of umbrella fish species over diverse spatial scales using a combination of species ranges, lifehistory traits, and species vulnerability scores. The approach also uses expert opinion to validate methods and results.3. This approach was applied to native fishes in California, and results for two river basins are explored in the context of instream flow management. These examples illustrate how the results could help address two common instream flow management challenges in California: (i) the lack of information related to speciesspecific flow requirements in basins with many species; and (ii) the need to move beyond a single species approach to flow management. In addition, the results indicate that the protection of native fishes in California would provide cobenefits for other aquatic and riparian taxa. 4.A key benefit of this approach is that the data used to select suites of umbrella species (e.g. species ranges, life-history traits, climate vulnerabilities) are widely available at varying degrees of specificity for most freshwater fishes. Therefore, this flexible approach could be applied in other regions to aid managers in making freshwater conservation decisions, such as for instream flow strategies, in an efficient and cost-effective manner.

“…In turn, the comparative approach is often used in the context of ecological congruence and surrogate taxa (e.g. Heino et al, 2009; Magg et al, 2019). Finally, studies using both approaches are also possible as researchers can be interested in ecological congruence between two different groups (e.g.…”

Going across taxa in functional ecology: Review and perspectives of an emerging field

Functional Ecology

The emergence of functional ecology has changed the focus of ecological research from investigating patterns of species diversity to understanding how species traits relate to specific ecological processes generating these patterns. Traits, ecological patterns and processes can be shared and driven by species from distantly related taxonomic groups. Crossing the boundaries among distantly related taxonomic groups is still a challenge and a critical knowledge frontier in functional ecology. A cross‐taxa approach, merging trait data across distantly related taxonomic groups, could fill this gap. In this context, functionally analogous traits, that is traits that may have distinct ontogenetic origins yet represent similar processes, comprise an important recent advance in functional ecology. However, which taxa and traits (be them analogous or not) have been used in research with multiple taxa, and whether (and how) these data have been combined, still needs to be elucidated. We reviewed articles published in the last 75 years to investigate the use of traits in functional research involving multiple taxa. Our search returned 1006 articles, and a subset of 96 was filtered for data extraction. Studies covered a total of 134 taxa and 491 different traits; they were predominantly observational, and focussed on community ecology and ecosystem monitoring. Our review showed that current knowledge in this field relies on a limited number of response variables, particularly taxonomic diversity (e.g. species richness and abundance within functional groups). Also, the field relies on a limited number of taxa (e.g. plants, birds and mammals) and trait types (diet, size, habitat and dispersal). Two‐thirds of the articles (n = 72) used functionally analogous traits, and one‐third of them (n = 32) employed a cross‐taxa approach. We mapped the limitations of current research in functional ecology involving multiple taxa, presented ecological questions to a functional cross‐taxa research and showed directions to pushing the limits of this research field. Our review aimed to encourage researchers in the field of functional ecology to move beyond single taxa and traits, and to integrate more branches and dimensions of the Tree of Life in their research.
