Final Report 1
Sand pit for Biodiversity at Cep II quarry Researcher: Klára Řehounková Research group: Petr Bogusch, David Boukal, Milan Boukal, Lukáš Čížek, František Grycz, Petr Hesoun, Kamila Lencová, Anna Lepšová, Jan Máca, Pavel Marhoul, Klára Řehounková, Jiří Řehounek, Lenka Schmidtmayerová, Robert Tropek Březen – září 2012 Abstract We compared the effect of restoration status (technical reclamation, spontaneous succession, disturbed succession) on the communities of vascular plants and assemblages of arthropods in CEP II sand pit (T řebo ňsko region, SW part of the Czech Republic) to evaluate their biodiversity and conservation potential. We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits. -
Folk Taxonomy, Nomenclature, Medicinal and Other Uses, Folklore, and Nature Conservation Viktor Ulicsni1* , Ingvar Svanberg2 and Zsolt Molnár3
Ulicsni et al. Journal of Ethnobiology and Ethnomedicine (2016) 12:47 DOI 10.1186/s13002-016-0118-7 RESEARCH Open Access Folk knowledge of invertebrates in Central Europe - folk taxonomy, nomenclature, medicinal and other uses, folklore, and nature conservation Viktor Ulicsni1* , Ingvar Svanberg2 and Zsolt Molnár3 Abstract Background: There is scarce information about European folk knowledge of wild invertebrate fauna. We have documented such folk knowledge in three regions, in Romania, Slovakia and Croatia. We provide a list of folk taxa, and discuss folk biological classification and nomenclature, salient features, uses, related proverbs and sayings, and conservation. Methods: We collected data among Hungarian-speaking people practising small-scale, traditional agriculture. We studied “all” invertebrate species (species groups) potentially occurring in the vicinity of the settlements. We used photos, held semi-structured interviews, and conducted picture sorting. Results: We documented 208 invertebrate folk taxa. Many species were known which have, to our knowledge, no economic significance. 36 % of the species were known to at least half of the informants. Knowledge reliability was high, although informants were sometimes prone to exaggeration. 93 % of folk taxa had their own individual names, and 90 % of the taxa were embedded in the folk taxonomy. Twenty four species were of direct use to humans (4 medicinal, 5 consumed, 11 as bait, 2 as playthings). Completely new was the discovery that the honey stomachs of black-coloured carpenter bees (Xylocopa violacea, X. valga)were consumed. 30 taxa were associated with a proverb or used for weather forecasting, or predicting harvests. Conscious ideas about conserving invertebrates only occurred with a few taxa, but informants would generally refrain from harming firebugs (Pyrrhocoris apterus), field crickets (Gryllus campestris) and most butterflies. -

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4. -

Quantitative surveys of chrysopids from northwestern Europe were analysed. A total of thirty-five species are known within the zone although only twenty-six were recorded. Only the common green lacewings (i.e. the sibling species of the Chrysoperla carnea complex, here not differentiated) were elsewhere abundant comprising more than 3/4 of the specimens in all countries and reaching 97 % in Belgium. For the scarcer species, comments are given on their enhanced geographic range. The French fauna shows 19 species, six are exceptional (< 0.1 %) such as the Atlanto-Mediterranean Dichochrysa picteti. Five species are considered rare (1<Q ≤ 5 %): Chrysopa perla, Ch. phyllochroma, Dichochrysa flavifrons, D. inornata and D. prasina. The fauna of both Great Britain and Ireland has the same faunistical richness but manifests a more balanced equitability. Chrysopa perla, Dichochrysa flavifrons and Cunctochrysa albolineata are uncommon (5 < Q ≤ 15 %), the others are at least rare. -
Seasonal Adaptations of Green Lacewings (Neuroptera: Chrysopidae)
REVIEW Eur.1. Entomol. 102: 317-324, 2005 ISSN 1210-5759 Seasonal adaptations of green lacewings (Neuroptera: Chrysopidae) MICHEL CANARD 47 chemin Flou de Rious, F-31400 Toulouse, France; e-mail: [email protected] Key words. Chrysopidae, green lacewing, seasonal adaptation, diapause, voltinism, overwintering, eycle synchronization, wintering chambers Abstract. Seasonal adaptations of green lacewings (Neuroptera: Chrysopidae) and their role in the control of aphid populations are discussed. The chrysopids of temperate zones face seasonal changes and must escape cyclic adversity. One way is via the number of broods per year. Most green lacewings are facultatively multivoltine, with the succession of generations most often regulated by photomediated diapause. Others are univoltine and some extend their life-cycle to two years in cold or dry environments. Synchroni zation is an important feature of seasonality, often starting in spring. In univoltine species, it is sometimes the result of subtle mecha nisms, such as double contradictory signals (short plus long day lengths) for reactivation in spring, or a multi-receptivity of the preimaginal instars to photoperiod throughout a year, combined with photo-controlled and synchronized egg laying in late summer. Only one North American species is known to enter a surnumerary food-mediated diapause in summer. Every postembryonic instar may undergo diapause depending on the species. The timing and impact of the spring resumption in aphid consumption depends on their overwintering strategy. As far is known, chrysopids are intolerant of freezing, but their supercooling points are low enough to enable them to endure hard frost. The numbers of overwintering specimens of green lacewings in the field depend on the structure of the as~emblages in the pre vious growing season. -

December 2019 Suzanne Burgess and Joanna Lindsay Saving the small things that run the planet Summary Of the 70 species of lacewing recorded in the United Kingdom, at least forty-one of them have been recorded in Scotland, with four only being recorded in Scotland. The Bordered brown lacewing (Megalomus hirtus) was previously known from only two sites in Scotland, at Salisbury’s Crags in Holyrood Park, Edinburgh and at Doonie Point by Bridge of Muchalls in Aberdeenshire. Scottish Natural Heritage (SNH) provided funding to Buglife for year two of the Bordered Brown Lacewing project to run surveys and workshops to raise awareness and improve participant’s identification skills of the different species of lacewing and their allies (alderflies, scorpionflies and snake flies). With the help of volunteers, year two of the project successfully found twenty two adults of the Bordered brown lacewing. Two new areas were discovered at Holyrood Park at rocky outcrops close to St. Anthony’s Chapel and a new population was discovered at Skatie Shore and Perthumie Bay by Stonehaven. A further nine adults were found by Dr Nick Littlewood at six locations from the war memorial south of Stonehaven to Portlethen Village. A total of 264 records of 141 different species of invertebrate, including five species of lacewing, were recorded during surveys and workshops run through this project from six sites: Holyrood Park, in Edinburgh; Hermitage of Braid and Blackford Hill Local Nature Reserve in Edinburgh; Skatie Shore and Perthumie Bay by Stonehaven; Doonie Point by Bridge of Muchalls; St Cyrus National Nature Reserve near Montrose; and Drumpellier Park in North Lanarkshire. -

To make up the values recorded on single samples, we operated by the bootstrap method. A classifying process cluster scatterplot was then established to assess the proximity of the different habitats. Shannon's and Hurlbert's indices are highly sensitive parameters of the structure of assemblages. Their analysis results in a diagrammatic typological approach to the biotopes, allowing unambiguous comparisons between various chrysopid assemblagcs. It is possible to characterize the state of these polyvalent predators as a function of different abundance and diversity, and this state can be a standard of value of good ecological function in ecosystems. Concerning farming consultation and environmental conservation, such an approach is new and could be promising for future agricultural and landscape managers. biodiversity / green lacewing / faunistic richness / diversity index I equitability index 1. -

Neuroptera, Chrysopidae, Chrysopa oculata, C. perla, antennae, cannibalism, palpi, pheromones, predator, semiochemical, sensory ablation Abstract. We investigated the ability of females of the aphidophagous chrysopids Chrysopa oculata and Chrysopa perla to distin- guish clean substrates from substrates with tracks of chrysopid first instars after ablation of various sensory organs potentially involved in the detection of oviposition-deterring semiochemicals (ODSCs). Also studied were effects of storage time on the degree of oviposition deterrence of substrates contaminated by larvae and by extracts of ODSC in intact females. C. oculata and C. perla laid significantly fewer eggs on substrates with conspecific larval tracks than on simultaneously provided clean substrates. Females of both chrysopids could perceive ODSCs solely through sense organs on the head. The oviposition of each species was significantly lower on contaminated than on clean substrates when any kind of sense organ on the head was completely removed, i.e. antennae, maxillary palpi, or labial palpi. C. oculata could still effectively differentiate substrates after ablation of both maxillary and labial palpi, indicating possible detection of volatiles via the antennae during flight. Only if all three pairs of sensory appendages were removed did females lay similar numbers of eggs on both substrates.
