ANÁLISIS. Create a Visme. Researcher. Researcher. Researcher. Researcher. Questions Vascular epiphytes make up about 9 % of all vascular plants globally but are clearly underrepresented in the temperate zones.
The accidental epiphytic occurrence of terrestrial species, in contrast, is common at these latitudes and can provide important insights in the evolution of obligate epiphytes. Here we present the results of the first two annual censuses of a planned long‐term study on accidental epiphytes. We particularly aim to identify: (1) the abundance and species richness of accidental epiphytes, (2) the dynamics of accidental epiphytism, (3) occupied substrates and microsites and (4) suitable host tree species.
Location Harz Mountains, Germany, Central Europe. Methods We surveyed more than 1200 trees in a low mountain range in two consecutive years for epiphytic individuals of vascular plants considering host tree species and occupied microsites.

Introduction Foundation species are spatially dominant, habitat‐forming organisms that enhance the richness and abundance of ecological communities (Bertness and Callaway 1994, Bruno et al. 2003).
Trees, freshwater macrophytes, seagrasses, reef‐forming bivalves, and corals are all examples of such foundation species which create habitat for other species with their own body tissue (Jeppesen et al. 1992, Ellison et al. 2005, Coker et al. 2014, Christianen et al. 2016, van der Zee et al. 2016, Ali and Yan 2017). A major factor thought to underlie foundation species’ enhancements of associated communities is their positive effect through their ability to modify their habitat (Govenar 2010). Habitat structure is suggested to enhance species richness through a number of potentially codependent non‐trophic mechanisms (Kovalenko et al. 2012). Spanish moss is a rootless bromeliad distributed from North Carolina, USA, to central Brazil.

Introduction The study of biotic interactions is essential for developing a predictive understanding of community assembly (Kraft & Ackerly, 2010; Michalet et al., 2015; Chalmandrier et al., 2017; Lekberg et al., 2018; Tylianakis et al., 2018) and ecosystem responses to environmental change (Harley, 2011; Cavieres et al., 2014; Polle & Luo, 2014; Graff & Aguiar, 2017).
Although studies of natural communities for a long time assumed that the dominant form of the inter‐specific interaction was competition (i.e. negative interactions; Connell, 1983; Kunstler et al., 2012; Bödeker et al., 2016; Lekberg et al., 2018), the role of facilitation (positive interactions) has recently been realized in many ecosystems (Callaway et al., 2002a; Brooker et al., 2008; He et al., 2013; Ettinger & Hillerislambers, 2017; Filazzola et al., 2018). Forest canopies offer an excellent opportunity for exploring interactions between clonality and inter‐specific facilitation. Materials and Methods. Error - Cookies Turned Off.

Fragmentation is expected to impede gene flow for many plant species that are restricted to remaining forest fragments. Epiphytes may be especially vulnerable to this effect of forest fragmentation because they depend on host trees. However, trees that remain in pastures may enhance connectivity across the landscape for epiphyte species that can thrive on such trees. To investigate this possibility, we studied the genetic structures of two such species on isolated pasture trees and surrounding forest, in relation to their local abundances in different habitat types and aspects of their reproductive biology including pollen and seed dispersal agents, and looked for evidence of increased or diminished gene flow.

A. Fine, Christopher Baraloto, Sabrina E. Russo, and Kabir G. Peay A new study suggests the answer to this question may lie in the fungi that grow in tree roots Why do we have “monodominance” in some tropical forests, but not in others? Tropical forests are the quintessence of biodiversity. One possible answer is the fungi that colonize the roots of monodominant trees. However, monodominant stands arise only in some tropical regions, and not others.
