Leaf water relations in epiphytic ferns

Courtney Campany, Jarmila Pittermann, Alex Baer, Helen Holmlund, Eric Schuettpelz, Klaus Mehltreter &
Opportunistic diversification has allowed ferns to radiate into epiphytic niches in angiosperm dominated landscapes. However, our understanding of how ecophysiological function allowed establishment in the canopy and the potential transitionary role of the hemi-epiphytic life form remain unclear. Here, we surveyed 39 fern species in Costa Rican tropical forests to explore epiphytic trait divergence in a phylogenetic context. We examined leaf responses to water deficits in terrestrial, hemi-epiphytic, and epiphytic ferns and related these findings...

Muscle fiber size, myonuclear domain, and fat mass phenotypes in pre-migratory snow buntings

François Vézina, Ryan O'Connor, Audrey Le Pogam, Aliyah De Jesus, Oliver Love & Ana Jimenez
In long-distance migrants, preparation for migration is typically associated with increases in fat and body mass, and with an enlargement of pectoralis muscle mass that likely improves flight performance. Although changes in muscle mass or size have been well described in migratory birds, potential changes in muscle ultrastructure during this transition still deserves scrutiny. Using outdoor captive snow buntings (Plectrophenax nivalis n = 15) measured during their transition into a spring migratory phenotype as a...

Data from: Putting vascular epiphytes on the traits map

Epiphyte trait data for the paper Hietz et al. 2021 Putting vascular epiphytes on the traits map. Journal of Ecology Plant functional traits impact the fitness and environmental niche of plants. Major plant functional types have been characterized by their trait spectrum, and the environmental and phylogenetic imprints on traits have advanced several ecological fields. Yet very few trait data on epiphytes, which represent almost 10% of vascular plants, are available. We collated >80,000 mostly...

Data from: Virulent disease epidemics can increase host density by depressing foraging of hosts

Rachel Penczykowski, Marta Shocket, Jessica Housley Ochs, Brian Lemanski, Hema Sundar, Meghan Duffy & Spencer Hall
All else equal, parasites that harm host fitness should depress densities of their hosts. However, parasites that alter host traits may increase host density via indirect ecological interactions. Here, we show how depression of foraging rate of infected hosts can produce such a hydra effect. Using a foraging assay, we quantified reduced foraging rates of a zooplankton host infected with a virulent fungal parasite. We then parameterized a dynamical model of hosts, parasites, and resources...
