A new species, Ateuchus tona, from the eastern Andes of Colombia is described and illustrated. The unique set of characters of this species, particularly the unusual sexual dimorphism in the sixth abdominal ventrite, which is largely expanded medially only in males, clearly separates this species from all other known species of Ateuchus. The species was found in 2004 during a single sampling event in a protected area. Since in Colombia most of the cloud forests are subject to extensive deforestation, additional sampling is needed to gather information about the species' conservation status. Additionally, two species, A. parvus and A. freudei, new to Colombia are presented rising the number of the Ateuchus species known for the country to eleven.

We investigated the intra- and trans-generational effects of larval diet on immune function, body size and development time of the greater wax moth, Galleria mellonella (Lepidoptera: Pyralidae). We found that moths reared on a diet diluted with cellulose (a low-nutrition diet) were about one-third smaller, had about one-fifth longer development time and exhibited about 10% stronger encapsulation responses as compared with moths reared on the standard diet. The low-nutrition parental diet prolonged the development time of male offspring that were fed the low-nutrition diet by about 4% and the development time of female offspring that were fed the standard diet by about 1%. However, females that were fed the low-nutrition diet attained about 6% greater body mass when their parents were reared on the low-nutrition diet. Our results add to the growing number of studies demonstrating that the nutritional history of parents can affect the performance of their offspring.

Age and sex are key information to interpret results of studies on birds' biology. As sexing monomorphic species is difficult, in this study we aimed to determine the degree of sexual size dimorphism in song thrushes migrating across the southern Baltic coast, and to develop reliable sexing criteria for future studies of this species. We ringed, measured and took blood samples of song thrushes at the Polish coast. Then we used molecular techniques to determine the sex of ringed individuals and to calculate functions from morphometrics for sexing birds from different age groups. Our results showed a degree of size dimorphism between sexes, more pronounced in adults than in immatures. Dimorphism was clearest in the size of the vestigial outermost primary, which was longer in females despite their smaller size, a likely result of different selection pressures during the breeding season. Differences between sexes were greater in adults than immatures, probably because the immatures are not exposed to selection pressures acting on older birds during migration and breeding. We developed equations allowing to estimate sex correctly of 81.5% of adults in spring and 81% in autumn, and of 63.3% immatures in spring and 63.6% in autumn. Thus, the equation for adults can be used with confidence, while those for immatures with caution.

We used a total of 589 independent photos of three species — the leopard cat (Prionailurus bengalensis), red fox (Vulpes vulpes) and North China leopard (Panthera pardus japonensis) — from 81 camera traps to study coexistence of those sympatric carnivores. We computed an occupancy model and ran single-season and two-species models to examine patterns in occupancy, detection and coexistence. Our study revealed simultaneous presence of red foxes and leopards both in space and in time. Leopard cats and leopards avoided each other, and red foxes and leopard cats coexisted particularly at night. Vegetation cover was found to be the most important factor in candidate models for site occupation.

Many parasitoid wasps parasitize herbivorous insect larvae growing within plant organs (e.g., fruits and leaves). As it is hard to identify the insect host species directly, one approach to deal with this issue is to identify it by means of molecular analysis from puparia left within plant organs after wasps emerge. Unfortunately, current barcoding methods are either too expensive or too inefficient for mass species identification. Here, we present a protocol that is comparatively inexpensive and rapid. It includes two major modifications in the barcoding process. One is to use a modified Chelex DNA extraction method, which performed best in PCR amplification and was the least costly and time-consuming among four candidate methods. The other is to use general PCR primers for the host taxon, which had the highest sequencing success rate when coupled with the Chelex DNA extraction method. Our protocol proved to be successful in identifying the hosts (i.e., tephritid fly species) of parasitoid wasps in a Tibetan alpine meadow. The protocol can be widely used for mass identification of insect host species from puparia tissues to facilitate the studies on host–parasitoid interactions.

Climate change is presumed to increase both the number and frequency of fluctuations in environmental conditions. Fluctuations can affect the ecological and evolutionary processes that make species more successful competitors. For example, fluctuating conditions can create selection pressures for traits that are profitable in adaptation to fast climate change. On an ecological timescale, environmental fluctuations can facilitate species competitive success by reducing other species' population sizes. Climate change could then enhance species invasions into new areas if fluctuation-adapted invaders displace their native competitors in chancing environments. We tested experimentally whether fast environmental fluctuations, either past (on an evolutionary timescale) or present (on an ecological timescale) affect species competitive success. Bacteria that evolved in either constant or fluctuating temperature were set to compete with the dominant invader Serratia marcescens, which had also evolved in either constant or fluctuating temperature. Moreover, the competition experiments were conducted in environments with similarly constant or fluctuating thermal conditions. The results showed that temperature fluctuations during competition, i.e. on an ecological timescale, made the invader more successful. Surprisingly, we found that the invaders' or its competitor species' evolution in fluctuating environments did not affect the outcome of the competition. Our study highlights the importance of the present environmental fluctuations in promoting species' competitive success and potentially facilitating biological invasions.

Leafhopper and planthopper (Auchenorryncha) assemblages were investigated at a lowland site in the United Kingdom supporting acidic and mesotrophic grasslands reverting from agricultural use, alongside remnants of semi-natural acidic heath. Further areas of agricultural land had been subject to soil inversion with or without addition of sulphur, heather brash and seed material to establish acidic heath or mesotrophic grassland. Eleven years after work commenced, Auchenorrhyncha assemblages of heath created on former arable land were most closely related to those of remnant semi-natural heath and reversion acidic grasslands. In contrast, an area of heath created on former pasture eight years previously, and at an earlier stage of development, supported an insect assemblage more closely related to those of mesotrophic grasslands. Time since creation, former land use and degree of isolation are identified as potential factors determining the similarity between Auchenorrhyncha assemblages of the remnant and created heaths.

Global change, including urbanization, affects species ecology. Social wasps (Vespinae) are ubiquitous in urban areas, which increases their encounters with humans. We studied social wasps in urban gardens and nearby urban woods in central Finland, using beer traps. Social wasps were common in gardens and woods, and overall wasp abundance was higher in the woods. Also, the most abundant and frequent species Vespula vulgaris was more abundant in the woods than in the gardens. Variation in the overall abundance and the abundance of V. vulgaris was great among trap locations, which likely results from wasps' social nesting habits. Neither the abundance of all social wasps nor that of V. vulgaris differed between July and August. Our study suggests that urban woods might increase wasp abundance in adjacent gardens. Vespula germanica — a species expanding its range northwards in Finland — was documented for the first time from central Finland. The ongoing global change is likely to change wasp communities and their encounters with humans in urban environments.

The intermediate disturbance hypothesis (IDH) suggests that the peak of species diversity occurs at intermediate-scale disturbances. The IDH received criticisms because many studies have shown that the relationship between disturbances and species diversity is generally not unimodal. We searched Web of Science for articles on IDH to study the applications of the hypothesis in animal and plant studies. We classified found articles into those which presented evidence in favour and against the IDH. Furthermore, we analysed the effects of article age and impact factor of the journal in which it was published on the number of citation this article received. We found that most arguments against the IDH were found in papers on aquatic ecology and in papers published in journals with higher impact factors. Those articles were also cited more often than those presenting evidence in support of the IDH. We thus can conclude that the IDH seems to be less supported in newer papers and particularly in those in the field of aquatic ecology.
中间扰动假说认为物种多样性的峰值出现在中等尺度的扰动中。IDH受到了批评，因为许多研究表明，干扰与物种多样性之间的关系通常不是单峰的。我们在Web of Science上搜索了有关IDH的文章，以研究该假说在动植物研究中的应用。我们将发现的文章分为支持和反对IDH的两类。此外，我们还分析了文章年龄和发表期刊的影响因子对文章被引次数的影响。我们发现，大多数反对IDH的论点出现在水生生态学的论文和发表在影响因子较高的期刊上的论文中。这些文章也比那些提供证据支持IDH的文章更常被引用。因此，我们可以得出结论，IDH似乎在较新的论文中得到的支持较少，特别是在水生生态学领域的论文中。

A new population of blind mole rat (genus Nannospalax) was discovered near the town of Albertirsa in north-central Hungary. We used newly designed primers to specifically amplify the whole mitochondrial cytochrome-b region and two nuclear DNA regions. Based on the most comprehensive taxonomic sampling to date, we compared this population with several other European blind mole-rat taxa. The results from both mitochondrial and nuclear regions have unequivocally placed the Albertirsa population into the monophyletic group of the Vojvodina blind mole rat (N. (leucodon) montanosyrmiensis), which turned out to be a sister clade to all other molecularly studied European Nannospalax. This study not only identified the fourth known population of an extremely rare rodent taxon but also calls for a taxonomic revision of European lesser blind mole rats (N. leucodon superspecies) to systematically evaluate the genetic structure of their populations and to understand the complex evolutionary history of these European rodents. The occurrence of the Vojvodina blind mole rat at this northern location helps to clarify the distribution area of this heavily data-deficient taxon. As currently understood, this lineage predominantly occurs in sandy grasslands of the Danube–Tisza Interfluve in Hungary and Serbia. Its distribution range and phylogenetic structure might reflect the importance of potential biogeographical barriers (e.g. large rivers) that shaped the blind mole rats' allopatric or peripatric speciation.
