Chapter 10 “Environmental DNA for functional diversity” discusses the potential of environmental DNA to assess functional diversity. It first focuses on DNA metabarcoding and discusses the extent to which this approach can be used and/or optimized to retrieve meaningful information on the functions of the target community. This knowledge usually involves coarsely defined functional groups (e.g., woody, leguminous, graminoid plants; shredders or decomposer soil organisms; pathogenicity or decomposition role of certain microorganisms). Chapter 10 then introduces metagenomics and metatranscriptomics approaches, their advantages, but also the challenges and solutions to appropriately sampling, sequencing these complex DNA/RNA populations. Chapter 10 finally presents several strategies and software to analyze metagenomes/metatranscriptomes, and discusses their pros and cons.

Abstract:Termite species and functional groups differ among regions globally (the functional-diversity anomaly). Here we investigate whether similar differences in biomass and abundance of termites occur among continents. Biomass and abundance data were collected with standardized sampling in Cameroon, Malaysia and Peru. Data from Peru were original to this study, while data from Cameroon and Malaysia were compiled from other sources. Species density data were sampled using a standardized belt transect (100 × 2 m) while the biomass and abundance measurements were sampled using a standardized protocol based on 2 × 2-m quadrats. Biomass and abundance data confirmed patterns found for species density and thus the existence of the functional diversity anomaly: highest estimates for biomass and abundance were found in Cameroon (14.5 ± 7.90 g m−2 and 1234 ± 437 ind m−2) followed by Malaysia (0.719 ± 0.193 g m−2 and 327 ± 72 ind m−2) and then Peru (0.345 ± 0.103 g m−2 and 130 ± 39 ind m−2). The biomass and abundance for each functional group were significantly different across sites for most termite functional groups. Biogeographical distribution of lineages was the primary cause for the functional diversity anomaly with true soil-feeding termites dominating in Cameroon and the absence of fungus-growing termites from Peru. These findings are important as the biomass and abundance of functional groups may be linked to ecosystem processes. Although this study allowed for comparisons between data from different regions further comparable data are needed to enhance the understanding of the role of termites in ecosystem processes on a global scale.

Lines Of Evidence

Clathrin-mediated endocytosis involves a coordinated series of molecular events regulated by interactions among a variety of proteins and lipids through specific domains. One such domain is the Eps15 homology (EH) domain, a highly conserved protein–protein interaction domain present in a number of proteins distributed from yeast to mammals. Several lines of evidence suggest that the yeast EH domain–containing proteins Pan1p, End3p, and Ede1p play important roles during endocytosis. Although genetic and cell-biological studies of these proteins suggested a role for the EH domains in clathrin-mediated endocytosis, it was unclear how they regulate clathrin coat assembly. To explore the role of the EH domain in yeast endocytosis, we mutated those of Pan1p, End3p, or Ede1p, respectively, and examined the effects of single, double, or triple mutation on clathrin coat assembly. We found that mutations of the EH domain caused a defect of cargo internalization and a delay of clathrin coat assembly but had no effect on assembly of the actin patch. We also demonstrated functional redundancy among the EH domains of Pan1p, End3p, and Ede1p for endocytosis. Of interest, the dynamics of several endocytic proteins were differentially affected by various EH domain mutations, suggesting functional diversity of each EH domain.

Abstract Nature, ecosystems and biodiversity provide human society with many benefits known as ecosystem services. Functional diversity is an important aspect of biodiversity. In this paper, we applied inductive approach to the identification, mapping and evaluation of ecosystem services of the Aegopodio-Alnetum glutinosae community in Tribeč Mts. The results from 2015 show that the alder floodplain forest represents one of the most productive forest ecosystems with seasonal maximum production of 59.03 g m−2, species diversity of N0 = 40 and functional diversity of FD = 10. The forage potential of this community is medium, the melliferous potential is high and the therapeutic potential was estimated as extremely rich in medicinal plants. From the functional groups for providing ecosystem services, woody plants and hemicryptophytes play the most significant role.

Moderating Role

Purpose Underpinned by the information processing theory, this study aims to investigate the relationship between functional diversity and team innovation by examining the moderating role of some selected cultural dimensions (power distance, uncertainty avoidance and masculinity-femininity) in the relationship between functional diversity and innovation. Design/methodology/approach A quantitative research method was used using a structured questionnaire as a tool to collect data from 251 respondents drawn from research institutions in Ghana. Data was analysed using simple regression and hierarchical multiple regression. In addition, a structural equation model was used to conduct confirmatory factor analyses to examine whether the variables in the hypothesized model for the study captured distinct constructs that the variables were designed to measure. Findings The study revealed that functional diversity was positively related to team innovation. The study also found that functionally diverse groups are more innovative when they exhibit low uncertainty avoidance, femininity and low power distance. Practical implications These findings suggest that practices such as team communication, honesty, respect and trust would foster team unity and commitment, which would enable members to share diverse expertise towards the creation and execution of new ideas and improvement of productivity in the country. Originality/value The study examined the relationship between functional diversity and team innovation by examining the moderating role of some selected cultural dimensions (power distance, uncertainty avoidance and masculinity-femininity) in the relationship between functional diversity and innovation.

The Relationship

This article opens up the black box of innovation and examines the relationship between functional diversity in software teams and the often neglected dimension of innovation – speed, over the two phases of innovation: creativity and idea implementation. By combining information processing view and social identity theory, the authors hypothesize that when collective team identification is low, functional diversity positively affects the time spent in the creativity phase; however, when collective team identification is high, this relationship is inverted U-shaped. When task cohesion is high, functional diversity negatively affects the time spent in the idea implementation phase; however, when task cohesion is low, this relationship is U-shaped. Results from 96 IT software-teams confirmed the authors' hypotheses. Theoretical and managerial implications are discussed.
