Gravitational energy and cosmic acceleration [PDF]
, 2007 Cosmic acceleration is explained quantitatively, as an apparent effect due to gravitational energy differences that arise in the decoupling of bound systems from the global expansion of the universe.

Apparent Competition and Vector-Host Interactions
Israel Journal of Ecology and Evolution, 2010 Infectious disease influences the dynamics of host populations and the structure of species communities via impacts on host demography. Species that share infectious diseases are well-known to interact indirectly through the process of apparent competition, but there has been little attention given to the role of vectors in these indirect interactions.

Natural enemies and biodiversity: The double-edged sword of trophic interactions
Mètode Science Studies Journal: Annual Review, 2019 Natural enemies, that is, species that inflict harm on others while feeding on them, are fundamental drivers of biodiversity dynamics and represent a substantial portion of biodiversity as well.

Intermediate behavior of Kerr tails [PDF]
, 2014 The numerical investigation of wave propagation in the asymptotic domain of Kerr spacetime has only recently been possible thanks to the construction of suitable hyperboloidal coordinates. The asymptotics revealed an apparent puzzle in the decay rates of

Predation determines different selective pressure on pea aphid host races in a complex agricultural mosaic. [PDF]
PLoS ONE, 2013 Field assessments were conducted to examine the interplay between host plant and predation in complex agricultural mosaic on pea aphid clover and alfalfa races. In one experiment, we examined the relative fitness on clover race (CR) and alfalfa race (AR)

The Unbearable Beingness of Light, Dressing and Undressing Photons in Black Hole Spacetimes
, 2012 Gravitational tidal forces acting on the virtual e+ e- cloud surrounding a photon endow spacetime with a non-trivial refractive index. This has remarkable properties unique to gravitational theories including superluminal low-frequency propagation, in ...

Competition among Aedes aegypti larvae. [PDF]
PLoS ONE, 2018 Adult Aedes aegypti mosquitoes are important vectors of human disease. The size of the adult female affects her success, fitness, and ability to transmit diseases. The size of the adults is determined during the aquatic larval stage.

Indirect effects of primary prey population dynamics on alternative prey
, 2014 We develop a theory of generalist predation showing how alternative prey species are affected by changes in both mean abundance and variability (coefficient of variation) of their predator's primary prey.
