LoPresti EF, Goidell J†, Mola JM*, Page ML*, Specht CD, Stuligross C*, Weber MG, Williams NM, Karban R. A lever action hypothesis for pendulous hummingbird flowers: experimental evidence from a columbine. Annals of Botany, early view.
----> a really nice write-up by Alun Salt here.
Many hummingbird-pollinated flowers have downward-facing flowers, despite other studies showing that hummingbirds do not like to feed on flowers with this orientation. In a columbine, the hummingbirds lever the flower up, thus not feeding in the non-preferred orientation; we experimentally found that the levering increases pollination success. We hypothesize that this mechanism works only in actinomorphic flowers, but hope that this simple study inspires increased attention on this somewhat odd trait.
LoPresti, EF, V. Pan†, J. Goidell†, M.G. Weber, & R. Karban. Mucilage-bound sand reduces seed predation but not by reducing apparency; a field test of 53 plant species. Ecology, early view: e02809.
Mucilaginous seeds, when wetted and dried, get encrusted by substrate. This substrate encrustation reduced seed predation by ants in 48 out of 53 tested species; interestingly, when we manipulated the color and thus how "unapparent" (=camouflaged) the seed was, the effect seemed to be largely physical - but future work should use birds or mammals.
Karban, R. LoPresti, EF; Pepi, A* & P Grof-Tisza. (2019) Induction of the sticky plant defense syndrome in wild tobacco. Ecology. 100: e02746.
When damaged, wild tobacco plants increase the stickiness on buds; this stickiness functions as a fly-trap and those dead insects feed a guild of scavenging predators that somehow increase plant fitness.
Karban, R; LoPresti, EF; Vermeij, GJ & R Latta. (2019) Unidirectional grass hairs usher insects away from meristems. Oecologia. 189: 711-718.
As you surely intuitively know, spines on most grass species face towards the tip. This is why you can run your fingers up a blade of grass but not down it. This orientation leads to herbivorous insects generally walking towards the tip of the grass, and away from the meristem (though a large caterpillar was not deterred). Field surveys and an experiment found more damage towards the tips of hairy grasses, but did not provide unequivocal evidence of a fitness effect.

Wildfires have become a ubiquitous feature of California shrub and woodlands, and are likely incurring pervasive ecological & evolutionary consequences. After wildfires burned much of McLaughlin reserve (Lake Co., CA) in 2015, bee communities shifted towards larger-bodied species. Individual plants of the annual mint Trichostema laxum also got bigger due to increased water, light, and nutrient availability, producing far more flowers per plant. We found that these two changes altered the outcrossing rate of this mixed-mating species; post-burn populations had a ~25% lower outcrossing rate compared to unburned populations.

LoPresti, EF; Robinson, MR*; Krimmel, BA* & GK Charles*. 2018. The sticky fruit of manzanita; potential functions beyond epizoochory. Ecology. 99: 2128-2130
Manzanita shrubs (Ericaceae) are found across many habitats in California. The fruit of many manzanita species are sticky and entrap insects. We outline a series of hypotheses for the functional significance of sticky fruit, in addition to the old ‘tried-and-true’ hypothesis of epizoochory (seed dispersal via sticking to animals). We outline the natural history of two species of manzanita (Arctostaphylos viscida and A. hooveri), and detail some small experiments we did to test the hypotheses we proposed. While epizoochory certainly occurs in this and other systems, the other interactions modified by sticky fruit are quite understudied.

LoPresti, EF. Polyphagy by omnivory: scavenging expands host range of a polyphagous caterpillar. 2018. Oecologia 186: 1007-1015
Many herbivorous insects opportunistically scavenge or eat other insects, and macroevolutionary research has indicated that this omnivory may be linked to the ability to consume many different types of host plants (polyphagy, a rare, but very important trait of herbivorous insects). I tested the highly polyphagous tobacco budworm (Heliothis virescens) on ten plants of varying suitability. On each, I gave some caterpillars dead fruit flies, and fed others the plant alone. On host plants of lower quality, scavenging helped the caterpillars' growth rates; however, on hosts of good (or terrible) suitability, they had no effect. This suggests that opportunistic carnivory may expand the host range of herbivores to hosts of lesser suitability, though it cannot overcome all mechanisms of host plant resistance.
LoPresti, EF; Krimmel, BA & IS Pearse. Entrapped carrion increases indirect plant resistance and intra-guild predation on a sticky tarweed. 2018. Oikos 127: 1033-1044
Plant defensive traits can mediate a surprising complexity of biotic interactions. In this paper, we detail a combination of observation and small experiments on two species of sticky tarweeds (Madia elegans and Hemizonia congesta). We first outline the interesting food webs found on these plants from our five years of work in these systems. Entrapped insects attract predators, and this protects the plant from caterpillars and weevil larvae. However, when multiple predators co-occur, they often eat each other (intraguild predation - the photo to the left shows a lynx spider eating a stilt bug). We added and subtracted carrion to explore these interactive effects, and found that the amount of intraguild predation depended on the amount of carrion. Interestingly, even at high levels of intraguild predation, the effect of predators on the plant was still beneficial, through reductions in herbivores.

Ecological Entomology 43: 154-161 Many sticky plants end up covered in windblown sand or other substrates. To explore the potential defensive role of this formidable armor, we examined effects of entrapped sand on the two herbivores with different feeding strategies: the externally-feeding sphinx moth, Hyles lineata, and an internally-feeding sun moth, Lithariapteryx abroniaeella. We showed that entrapped sand abraded the mandibles and caused reductions in growth rate and pupal weight of the sphinx moth Hyles lineata. When given the choice, Hyles caterpillars also preferred to consume nonsandy foliage. In contrast, the leaf mining caterpillar had no aversion to sand on the surfaces of the plant. -> Press coverage here and here (paywall - I haven't even been able to read it!). |

LoPresti, EF. Artificial rainfall increases herbivory on an externally-defended forb. 2017. Arthropod-plant Interactions 11: 871-874
Atriplex rosea, a California summer growing chenopod, is covered in a thin layer of exudates which protect it from herbivory. In the presence of artificial rainfall (it doesn't rain in the CA summer at this location), plants suffer increased herbivory from a leaf beetle. This simple experiment demonstrates that external defenses are liable to be changed by the abiotic environment in potentially important ways.

LoPresti, EF & Morse, DH. 2017. A parasitoid's odd pupal vigil. Ecology 98: 1722-1723
This short paper details our attempts to understand why some male Phaeogenes hebrus – a wasp that parasitizes Herpetogramma thesausalis moths at the pupal stage - clung to certain host moth pupae, even when the surrounding leaf shelter was manually opened. We found that those pupae contained pre-emergence female wasps. We did a little experiment and found that mating success of the male parasitoids was far higher in small containers than in progressively larger ones. The odd behavior of clinging to a female pupae for a day or more before emergence – mediated by the wasp’s ability to select pupae hosting a female conspecific – may increase male reproductive success by ensuring mating prior to their leaving the caterpillar shelters.

Dragonflies are very vulnerable to bird predation when they leave ponds to molt from their aquatic nymphal stage into winged adulthood. Following an observation that nymphs congregate on thistles to molt, we tested their preference and survival on spiny and complex plants, using fake plant models. We found that both traits are preferred, and protect the insects during this critical transition.

LoPresti, EF & K Toll. 2017. The three criteria for resistance by carrion provisioning; insect entrapment and predator enrichment on Mimulus bolanderi. Ecological Entomology, 42: 230-234. An ephemeral, fire-following sticky monkeyflower (Diplacus [Mimulus] bolanderi.) seems to get protection from bodyguarding predators that feed on entrapped insects. We discuss the natural history of this plant species, the fact that this indirect defense is very facultative, as well as ways to test this potential indirect defensive strategy. |

LoPresti, EF and Karban, R. 2016. Chewing sandpaper: grit, plant apparency and plant defense in sand-entrapping plants. Ecology. doi: 10.1890/15-1696 (natural history supplement here)
-> press: here, here and here
-> radio segment here
Many sticky plants in sandy areas incidentally entrap sand. While this has been hypothesized as a defense against chewing herbivores several times since William Beal first proposed it in 1878, the idea had not been tested. In manipulative experiments on Abronia latifolia and Navarettia mellita, we found that sand is an effective defense against chewing herbivory, and that this crusty covering is not acting as camouflage, but rather as a direct defense.
LoPresti, EF and MG Weber. 2016. Breaking barriers in evolutionary biology: a pioneering woman in science and her early theory of plant chemical macroevolution. American Naturalist. 188: 2-4
Marj and I summarized and contextualized a really cool paper by Helen de Abbott about how plant chemistry evolves; the first written of this topic at all. While the specifics she detailed were mostly incorrect (as she was working off a massively flawed phylogeny), her ideas of chemical evolution were a century ahead of her time!

This charismatic large beetle has been lost in almost all of its former range. Here we summarized decades of reintroduction work on Nantucket Island including movement of marked individuals, breeding success, overwintering success and more. While this reintroduction has been largely unsuccessful, we found methods that might work in this and other future ABB reintroduction projects.

LoPresti, EF. 2016. Chemicals on plant surfaces are a heretofore unrecognized, but ecologically-informative, class for investigations into plant defense. Biological Reviews. 91: 1102-1117
A great diversity of plants have chemical defenses on their surfaces, secreted there by a multitude of specialized tissues. These chemicals are not usually considered a class of their own. However, because they are in a different location than most chemical defenses, their modes of activity and interactions with other organisms and the environment fundamentally differ from internal defenses (at least, that's what I try to convince you of in this paper!).

Given that most ecologists do lots of incidental natural history, we advocate that people include data and observation in a supplement as to give future scientists information on the system.

A sticky columbine is attractive to small flying insects, which become entrapped on its surfaces. These dead insects provision predatory bugs and spiders, which reduced herbivory on the plant in a manipulative experiment.
