Pollen transfer from invasive Carpobrotus spp. to natives - A study of pollinator behaviour and reproduction success (2008, background): “Pollinator populations also exhibit strong dynamics at a local scale (Roubik, 2001).”
Environmental factors affecting bee diversity in urban and remote grassland plots in Boulder, Colorado (2009, methodology): “…can be difficult to sample because of large spatial and temporal variability (Herrera 1988; Minckley et al. 1999; Cane and Tepedino 2001; Roubik 2001; Williams et al. 2001) but several researchers have had success in making comparisons of insect surveys among habitats sampled with the…”
Insect visitation and pollen deposition in an invaded prairie plant community (2006, background): “Year-to-year variation in pollination studies is to be expected: the variability inherent in pollination systems is well documented and many have warned of the difficulties in interpreting shortterm studies (Fishbein and Venable, 1996; Herrera, 1988, 1995; Price et al., 2005; Roubik, 2001).”

Interpreting insect declines: seven challenges and a way forward (2020, background): “For most insects, high inter-annual variability is the norm rather than the exception (e.g. Redfearn & Pimm, 1988; Roubik, 2001), but it poses serious problems in determining what the baseline reference state should be for historical abundance, and inherently increases the length of time series requ”
Confounding factors in the detection of species responses to habitat fragmentation (2005, background): “…) Synergies magnify the impacts of fragmentation (a ) Fragmentation and pollination There are no data that unequivocally relate habitat fragmentation with long-term pollinator declines (Cane & Tepedino, 2001), perhaps because plant-pollinator systems exhibit wide temporal variation (Roubik, 2001).”
Tropical Forest Fragments Enhance Pollinator Activity in Nearby Coffee Crops (2004, background): “Large fluctuations in insect populations are common, including those of important pollinators ( Wolda 1978; Roubik 2001).”
Rapid ecological replacement of a native bumble bee by invasive species. (2013, background): “Moreover, plant–pollinator systems are inherently dynamic and therefore multi-year studies are necessary to demonstrate genuine trends of pollinator-population shifts in nature (Roubik 2001).”
