Data from: Changes in liana density over 30 years in a Bornean rain forest supports the escape hypothesis

David Newbery, Cedric Zahnd & Elaine Campbell
In two permanent plots of lowland dipterocarp forest at Danum a liana census in 1988 was repeated in 2018 using the same method. Trees ≥ 30 cm gbh (girth at breast height) were recorded for number of lianas ≥ 2 cm gbh on their stems. The forest was evidently in a late stage of recovery from a large natural disturbance. Over the interval, mean number of lianas per tree decreased by 22 and 34 %...

Endosperm-based incompatibilities in hybrid monkeyflowers

Taliesin Kinser, Ronald Smith, Amelia Lawrence, Arielle Cooley, Mario Vallejo-Marín, Gregory Conradi Smith & Joshua Puzey
The sexual endosperm is an angiosperm innovation central to flowering plant reproduction. Genomic interactions between parental alleles control its development and help determine seed viability. These interactions are characterized by genomic imprinting, where expression from certain genes is parent-specific. Unsuccessful imprinting has been linked to failed hybridization between plants of different species or ploidies. Here, we describe an endosperm-based barrier between Mimulus guttatus, a diploid, and M. luteus, an allotetraploid. Hybrid seeds suffer from underdeveloped...

Bryophyte microecosystem experiment

Adam Vanbergen, Claire Boissieres, Alan Gray & Daniel Chapman
Ecosystems face multiple, potentially interacting, anthropogenic pressures that can modify biodiversity and ecosystem functioning. Using a bryophyte-microarthropod microecosystem we tested the combined effects of habitat loss, episodic heat-shocks and an introduced non-native apex predator on ecosystem function (chlorophyll fluorescence as an indicator of photosystem II function) and microarthropod communities (abundance and body size). Photosynthetic function was degraded by the sequence of heat-shock episodes, but unaffected by microecosystem patch size or top-down pressure from the introduced...

Data from: Negative density dependence in the mortality and growth of tropical tree seedlings is strong, and primarily caused by fungal pathogens

Kirstie Hazelwood, Harald Beck & C. E. Timothy Paine
Natural enemies have been implicated as agents of negative density dependence (NDD) in tropical forests, but their relative contributions to NDD, and thus to the maintenance of diversity, are largely unknown. We monitored the rates of survival and relative growth rates on seedlings for ten years in tropical moist forest in Manu National Park, Peru. We then experimentally manipulated the plots to exclude fungal pathogens, insects, small mammals, and large mammals for an additional 31...
