AbstractThe Carabidae family (Coleoptera) is used frequently for its bioindication potential to detect the environmental burden. In 2013 and 2014, we studied the correlation of Carabidae on the biotopes of six areas in the Veporské vrchy Mts and the Juhoslovenská kotlina basin by using pitfall traps, Möricke plates and Bambara beetle traps. Out of 432 recorded specimens of beetles (53 species, 15 families), the Carabidae family were the highest number of species and specimens represented, with which we confirmed higher anthropogenic interference and disturbance of ecosystems in the Juhoslovenská kotlina basin. This statistic confirms the presence of the following species typically found on arable land: Anchomenus dorsalis, Calathus fuscipes fuscipes, Harpalus affinis and Pseudoophonus rufipes. The ecosystems in the Veporské vrchy Mts region show less disturbance, and the anthropological impact is smaller, indicated by the presence of the Carabus problematicus species, an important indicator of the conservation of natural forest ecosystems.

Ecological Requirements

The number of remarkable species on a locality is an important indicator of locality value. The ecological requirements of the rare species may help to target correct landscape management activities. Our objective was to find out if standardly used capture methods for different group of invertebrate are able to detect really representative composition of species including rare taxa. Our experiment was carried out at the Moravský kras Protected Landscape Area (Macošská and Vilémovická stráň slope) where secondary dry grasslands are typical for each investigated locality. We used five groups of invertebrates (spiders, ground beetles, rove beetles, leaf beetles and weevils) and three capture methods (pitfall traps, sweeping on vegetation and yellow Möricke traps). Arthropods were determined and classified according to their rarity. Using the three capture methods, we obtained in total 127 spider species (Areneae), 31 ground beetle species (Carabidae), 29 rove beetle species (Staphylinide), 52 leaf beetle species (Chrysomelidae) and 55 weevil species (Curculionidae).Results showed that the different capture methods significantly influenced number of detected remarkable species. It was statistically proved for spiders (P = 0.025), weevils (P = 0.038) and marginally also for rove beetles (P = 0.051). Spiders of climax (C species) and semi-natural (SN species) habitats were rather detected by pitfall traps, whereas spiders of disturbed habitats were collected by sweeping on vegetation and Möricke yellow pans eventually. Relict species of weevils (R species) were detected by pitfall traps, typical species (T species) were collected by Möricke yellow pans and expansive species (E species) were found by sweeping on vegetation.

Moisture Conditions

Riparian hardwood forests of Quercus robur, Ulmus spp and Fraxinus spp that are present along major rivers are valuable communities protected by the EU Habitat Directive and recommended for monitoring. Part of the reason for that is relative rarity on the scale of Europe as a whole, and also in Poland. This in turn reflects the way in which fertile habitats were, in their majority, deforested long ago, drained and changed into grasslands or arable land. Additionally, the greater part of these habitats have lost their specific features, as a result of river engineering and – primarily – the construction of the river embankments that have acted to limit flooding and alluvial processes, in that way also initiating change in the composition of both soils and plant communities. Specifically, this article presents selected results of the research project: Riparian hardwood forest services in the middle Vistula river valley. One of the main objectives thereof was to assess the condition of forest ecosystems from which flooding has now been absent for at least 50 years, as well as to prepare guidelines for actions necessary to maintain or restore their diversity, and proper ecological and biological functions. Our research questions therefore revolved around components of riparian hardwood forest ecosystems have been most changed … and why? The research was conducted in six riparian hardwood forests (to date unmonitored) located in the valley of the middle Vistula (in Mazowieckie voivodship). Relevant work was carried out using the standard monitoring guidelines – as primarily based on an assessment of vegetation composition and structure together with water conditions. However, in the work in question, these were augmented by additional analyses allowing for detailed characterisations of soil, the topoclimate, and the species diversity achieved by selected groups of invertebrate (Hymenoptera: Apidae: Bombus and Haplotaxida: Lumbricidae). The communities selected represent multi-functional, species-rich forests. Extensive use of the studied riparian mixed forests ensures that deadwood resources are quite considerable. Moreover, the studied forests exert a strong impact when it comes to mitigation of climate locally. The observed soil types indicate fertile and biologically-active habitats, as well as to soil development largely determined by the height of the groundwater table causing the gleyic process in the lower parts of profiles. However, in some forest patches it is possible to note transformations related to habitat drying, with significant canopy gaps and disturbances of topsoil and the undergrowth. There was a great abundance of invasive alien plant species (mainly Impatiens parviflora) in the undergrowth. Moisture conditions have an impact on the occasional occurrence of Lumbricidae associated with wet and flooded areas. In turn, the domination by Bombus of open-habitat species indicates a transformation of forest structure, and the patchy nature of riparian forests located in a rural landscape. The obtained results demonstrate that protective actions should focus on ensuring adequate soil-moisture conditions, and on restoring the natural structure of vegetation with a view to invasions of alien species being hampered. Another important issue is the proper use of land adjacent to forest patches, as fallows prove to be invaded quickly by the kenophytes preferring abandoned and disturbed places.

The population dynamics and genetic qualities of stem height and dbh of the populations of Milicia excelsa, Pouteria adolfi-fridercii, Antiaris toxicaria and Prunus africana were assessed and studied in 14 forest ecosystems in south and south-western Ethiopia. A systematic random quadrat sampling technique was employed to identify potential habitat area for selected timber species in south and south-western Ethiopia. So, a total of 10 parallel transect lines were set out across each forest habitat. Milicia excelsa was assessed in four forest ecosystems; Bebeka -Duduka natural forest (45 tree stem ha-1) and Yayu coffee mixed forest (40 tree stem ha-1) appeared to have relatively denser population of M. excelsa compared to the other pilot forests. Similarly, statistically larger stem height (m) is observed in Bebeka-Duduka natural forest (x̅=29.5, SD=4.2) and larger dbh size (cm) in Bebeka 1 coffee mixed forest (x̅=48.5, SD=25.2) at p<0.05. Hence, Bebeka-Duduka natural forest and Bebeka 1 coffee mixed forests are identified for in-situ SPA establishment project of the target species. Pouteria adolfi-fridercii was assessed in eight forest ecosystems; Masha-Gora shewi forest appeared to have dense population of P. adolfi-fridercii (150 tree stem ha-1) followed by Bebeka-Kebereta (80 tree stem ha-1) as compared to the remaining pilot forests. However, statistically larger stem height (m) is scored in Bebeka 2 natural forest (x̅=30.6, SD=2.98) and Bebeka-kebereta forest (x̅=30.0, SD=4.4) and larger dbh size (cm) in Bebeka 2 natural forest (x̅=96.5, SD=19.9) at p<0.05. So, Bebeka 2 natural forest and Bebeka-kebereta forest are identified for SPA establishment project of the target species. Antiaris toxicaria was assessed in two forest ecosystems where both forest habitats appeared to have the same density of Antiaris toxicaria in hectare. Moreover, analyses of mean stem height (cm) of Bebeka 1 forest (x̅=21.4, SD=5.2) and Bebeka-kebereta forest (x̅=22.4, SD=2.7), and mean dbh size (cm) of Bebeka 1 forest (x̅=48, SD=16.4) and Bebeka-kebereta forest (x̅=48, SD=8.2) appeared to have not significantly different at p<0.05. Prunus africana was assessed in five forest ecosystems; Masha-Gora shewi forest appeared to have dense population of Prunus africana (150 tree stem ha-1) followed by Kaho-shemeta forest (130 tree stem ha-1) as compared to the remaining pilot forests. However, statistically larger stem height (m) is scored in Kaho-shemeta natural forest (x̅=31, SD=7.6) and larger dbh (cm) in Masha-Gora shewi forest (x̅=64.7, SD=28.2) at p<0.05. As the result, Kaho-shemeta natural forest and Bonga-Teja-adela forest are identified for establishment of seed production area of the target species in-situ. Hence, while implementing the project of domestication and seed production area establishment in south and south-western Ethiopia, in-situ and ex-situ areas must be selected and delineated in accordance with this preliminary information of the population dynamics and genetic qualities of stem height and diameter at breast height. The survey data generated in this study would bridge the research gap in relation to the population status of the target tree species in the designated area.

The Difference

Few research on the entomofauna associated to forest plantations with Swietenia macrophylla (King) in Brazil has been reported. The aim of this study was to analyze the Coleoptera communities in forest ecosystems with S. macrophylla, Brazilian mahogany, with emphasis on the diversity of families and the main functional groups. The insects were collected through pitfall traps in three forest ecosystems: monoculture, consortium and forest enriched with Brazilian mahogany, during dry and rainy periods in two consecutive years. The identification of the captured insects occurred in the entomology laboratory of the Federal Rural University of Amazonia. The analysis was performed through Past Paleontological Statistic 3.14 and ANAFAU, where the difference was considered significant only when p ? 0.05. 11,358 specimens from 21 families were captured, of which 8,058 were sampled in the rainy season and 3,299 in the dry season. There was influence of seasonality and types of forest ecosystems during collection. The families Nitidulidae, Staphylinidae, Carabidae and Meloidae presented greater abundance and richness in the complex ecosystems. Anobiidae, Cerambycidae, Bostrichidae, Brentidae, Buprestidae, Curculionidae, Elateridae, Chrysomelidae and Lagriidae were considered to be pests and common to all studied ecosystems; however, the families Nitidulidae, Scarabaeidae, Tenebrionidae and Passalidae had the function of decomposers; Carabidae, Coccinellidae, Histeridae, Meloidae, Staphylinidae, Cantharidae and Hydrophilidae were the predators.

The use of subterranean traps is a relatively novel method to sample ants, and few studies have evaluated its performance relative to other methods. We collected ants in forests, savannas, and crops in central Brazil using subterranean pitfall traps and conventional pitfall traps placed on the soil surface. Sampling duration, soil depth, and sprinkling vegetal oil around traps all tended to affect the number of species found in subterranean traps. Sixteen percent of the species collected in subterranean traps were unique, and most of these had cryptobiotic morphology (i.e., were truly hypogaeic species). Surprisingly, however, subterranean and conventional traps were similarly efficient at capturing cryptobiotic species. Furthermore, subterranean traps captured far fewer species in total than conventional traps (75 versus 220 species), and this was true in all three habitats sampled. Sampling completeness increased very little using a combination of conventional and subterranean traps than using just conventional traps.

Abstract: The objective of this work was to survey soil ants in Bt and non-Bt maize (Zea mays) crops, and to compare their effect on the soil ant community. Nine pitfall traps, 10 m apart, were installed in a central area (900 m2) of each of the following treatments (2,500 m2): conventional maize; maize modified with the Cry1F, Cry1Ab, and Vip3A proteins; and a native vegetation area. Fortnightly collections were conducted during four periods (complete producing cycles) of the crop, from 2011 to 2013. The number of ant species varied from 25 in Bt maize (Vip 3A) to 58 in Bt maize (Cry 1F). The treatment with conventional maize showed the highest Shannon-Wiener diversity index (H’ = 2.60). Jaccard’s index showed that there is dissimilarity between the cultivated maize areas and the native vegetation area in most treatments, and that Bt and non-Bt maize show similarity in their soil ant assemblages. The cultivation of Bt maize does not affect the soil ant community. The subfamily Myrmicinae shows the highest number of species in all the collection periods, with 57, 41, 47, and 50 species in the first, second, third, and fourth periods, respectively. The genus Pheidole, belonging to this subfamily, shows the greatest number of species.
