New Phytologist paper on veto in masting is out

Variable, synchronized seed production, called masting, is a widespread reproductive strategy in plants. Numerous ideas were proposed to explain this bizarre reproductive behavior of trees, but there is no consensus how the synchrony among individual plants happen. In the recent study, we explored the environmental veto hypothesis, which assumes that reproductive synchrony is driven by…

Extremadura field season about to start

Last week, we arrived at the University of Extremadura, at Raul Bonal lab. We are about to start the pollen addition experiments, testing the density-dependence and synchrony-dependence of pollination efficiency in Quercus ilex. This is financed by the grant I recently got, and this post explains more about the research. Meanwhile, we are enjoying the beautiful…

Our new masting paper in New Phytologist

Today, we’ve got the acceptation letter from New Phytologist! Good day to start a new week 🙂 In the paper, we first added ‘complete reproductive failure ‘ (or veto) as an additional parameter the to resource budget model. This new parameter describes the situation in which all plants within population experience failure (they do not…

Red oaks escape insect predation in their invasive range

In our recently published paper, we showed that red oaks escape seed predation by weevils (Curculio spp.) in their invasive range. Compared to native oaks, and to red oaks in the USA, the rate of infestation was 10-times lower in red oaks in Poland. What is more, once weevils infest red oaks in Europe, the…

Large grant: role of pollen limitation in masting

I just received large grant from Polish National Science Foundation (over 100 000 euro) to run some cool masting experiments 😉 We will experimentally evaluate the role pollen limitation as a synchronizing factor in masting of oaks. We are going to test both density-dependence of pollen limitation, as well as phenology-dependence of it (see e.g….

Interview on masting and Lyme disease in Wyborcza

Few weeks ago I talked with Margit Kossobudzka about our research on mast seeding and Lyme disease. The interview is now published in Wyborcza (national-wide polish newspaper), and you can read it under this link. Enjoy! 🙂 You can also check the older posts about this work, e.g. here. And, of course, the original scientific paper here!…

New Scientist on our Lyme disease research!

In the April issue of New Scientist Chelsea Whyte write about the relationship between oak mast seeding, tick and rodent populations, and Lyme boreliosis risk in humans. The article is, of course, heavily based on the work of Richard Ostfeld lab, but they mention also our recent work. You can read the original story in the…

Test of “Lost generation hypothesis” accepted in Scientific Reports

Our paper showing that increased water temperature delays late-season phenology of mayfly was accepted today in Scientific Reports. In short, alternated regime of water temperature in rivers distunes insects inner clock. The larvae molted into subimago in late(er) autumn on the heated river. However, in late autumn temperature of water is already pretty low. Since…

Autumn field season is over

We have finished month-long intense field work testing the mechanisms of red oak invasion in European forests. During last few weeks we have sowed acorns of both species at different distances from trees (of red oak and European oak) to test whether seed transportation by rodents positively affects germination probability of acorns. We have also conducted seed…

Journal of Ecology paper available online

The main paper of my PhD thesis is now available online (not proof read yet, though) at the Journal of Ecology site. You can also find it at my RG profile. Hope you will like it! 🙂
