Interaction of climate change with effects of conspecific and heterospecific density on reproduction

2020

We studied the relationship between temperature and the coexistence of great tit Parus major and blue tit Cyanistes caeruleus, breeding in 75 study plots across Europe and North Africa. We expected an advance in laying date and a reduction in clutch size during warmer springs as a general response to climate warming and a delay in laying date and a reduction in clutch size during warmer winters due to density-dependent effects. As expected, as spring temperature increases laying date advances and as winter temperature increases clutch size is reduced in both species. Density of great tit affected the relationship between winter temperature and laying date in great and blue tit. Specifically…

Variation in clutch size in relation to nest size in birds

2014

© 2014 The Authors. Nests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, yet our current understanding of clutch size-nest size relationships is limited to small-scale studies performed over short time periods. Here, we quantified the relationship between clutch size and nest size, using an exhaustive database of 116 slope estimates based on 17,472 nes…

Large Blooms of

2018

ABSTRACT Biological soil crusts (biocrusts) account for a substantial portion of primary production in dryland ecosystems. They successionally mature to deliver a suite of ecosystem services, such as carbon sequestration, water retention and nutrient cycling, and climate regulation. Biocrust assemblages are extremely well adapted to survive desiccation and to rapidly take advantage of the periodic precipitation events typical of arid ecosystems. Here we focus on the wetting response of incipient cyanobacterial crusts as they mature from “light” to “dark.” We sampled a cyanobacterial biocrust chronosequence before (dry) and temporally following a controlled wetting event and used high-throug…

Beierwaltes nella corrente dell'eriugenismo: la duplex theoria e lo statuto trascendentale della manifestazione

2007

L'articolo ricostruisce e discute il nucleo tematico dell'interpretazione del platonismo medievale elaborata da Beierwaltes e segnatamente della funzione centrale in esso del pensiero dell'Eriugena, mostrandone l'operatività nei successivi sviluppi della dialettica della contrazione.

Early plant succession in two abandoned cut-over peatland areas

1990

Initial stages of plant succession (from 0 to 8 or 9 yr) were studied on abandoned peat harvest sites of two adjacent areas in Finland. At the Mustasuo area only 13 field layer species, all perennials, and 3 ground layer species became established during that period and species composition stayed relatively constant. All species occurred sparsely with low biomass. The Riitasuo area was colonized by 43 field layer and 19 ground layer species during the first 8 yr of succession. In that area the originally plantless sites were totally covered by plants within a few years. Many of the first species to arrive were annuals, most of which were soon replaced by perennial species. The great differe…

Providing a general framework about spin-off success factors in complex environments

2018

Spin-off organisations are the main vehicle for knowledge transfer from universities and/or high educational institutions (HEIs) to the economic system. Spin-off firms are complex phenomenon which requires particular conditions to its creation, survival and development. In the last decade, the scientific debate recognised the importance and the role of spin-off organisations, but the main factors and actors that impact on their creation, survival and development are not always clear. This paper aims to fill this gap, shedding light on this black box. In a first step, this research will identify the main 'success factors' for creation of spin-offs. In the second step, the relationship betwee…
