“…The least similar community to that in the fire-affected Garwolin Forest plot (G I) was found in the undisturbed oldgrowth stands in BialowieZa Primeval Forest (Fig. 3) (Durska 2013) Forest fires have many implications for biological diversity and not all species suffer from fire. It is known that the speed of recovery after fire is related to the fire intensity, and some invertebrates and fungi are dependent on or favored by fire (Dahlberg 2002, Saint-Germain et al 2004, Penttila et al 2013).…”

“…The data obtained from the plot in the center of the fire zone (G I) were compared to the data obtained for scuttle fly communities inhabiting pine forests (BialowieZa Primeval Forest and Pisz Forest) after anthropogenic (clearcutting, loggingwindthrow) and natural (left-windthrow) disturbances, as well as with scuttle fly communities from an intact forest habitat (old-growth) (for details see Durska 2013).…”

“…Among these Megaselia dominants of the open-area habitats, three species (polysaprophagous M. brevicostalis (Wood), saprophagous M. nigriceps (Loew 1866), and zoophagous M elongata (Wood)) were found in the highest numbers in the plot most affected by fire (G 1). However, Megaselia verralli (Wood), a known pyrophilous species (Prescher et al 2002) dominant in pine forest habitats after disturbances in Poland (Durska 2013), was found in very low abundance in the GF habitats (G I: n = 3; G 11: n = 1; G 111: n =1) ( Table 2).…”

“…The majority of the species in the three habitats were the species with sapro/mycophages larvae (S = 27) and a multivoltine life cycle. These species are most active during spring and autumn (for details see Durska 2013). Among the species with zoophagous larvae, e.g.…”

“…Furthermore, also Mega-Selia verralli, another characteristic dominant scuttle fly species in communities in the pine plantations (clear-cut) of the Polish Lowland as well as in the post-wildfire habitats in the Castanea sativa forests (Swiss Alps), was found in the fire-affected plot (GI). However, the number of individuals was extremely low (n = 3) ( Table 2) (Prescher et al 2002, Durska 2006, 2009, 2013.…”

Ecological consequences of fire on the scuttle fly communities were investigated in a pine forest in Poland (Garwolin Forest). Data from 1,243 identifiable individuals, representing 48 species, were used. The scuttle fly communities in fire-affected plots were similar in terms of the number of species but less diverse than those in an undisturbed reference plot. The response of the flies to the fire was species-specific. Four Megaselia species (M. brevicostalis, M. nigriceps, M. elongata and M. obscuripennis) were most numerous in the plot most affected by fire. Approximately three years after the fire the scuttle fly communities were relatively similar to those found in a clear-cut pine plantation (Bialowieza Primeval Forest) as well as to those in post-windthrow habitats (Pisz Forest) in which logs were removed or left. The Megaselia species are the winners in the fire affected habitats and seem to be more stress-tolerant than other genera ofthe scuttle flies.

Natural disturbances are increasing around the globe, also impacting protected areas. Although previous studies have indicated that natural disturbances result in mainly positive effects on biodiversity, these analyses mostly focused on a few well established taxonomic groups, and thus uncertainty remains regarding the comprehensive impact of natural disturbances on biodiversity. Using Malaise traps and meta‐barcoding, we studied a broad range of arthropod taxa, including dark and cryptic taxa, along a gradient of bark beetle disturbance severities in five European national parks. We identified order‐level community thresholds of disturbance severity and classified barcode index numbers (BINs; a cluster system for DNA sequences, where each cluster corresponds to a species) as negative or positive disturbance indicators. Negative indicator BINs decreased above thresholds of low to medium disturbance severity (20%–30% of trees killed), whereas positive indicator BINs benefited from high disturbance severity (76%–98%). BINs allocated to a species name contained nearly as many positive as negative disturbance indicators, but dark and cryptic taxa, particularly Diptera and Hymenoptera in our data, contained higher numbers of negative disturbance indicator BINs. Analyses of changes in the richness of BINs showed variable responses of arthropods to disturbance severity at lower taxonomic levels, whereas no significant signal was detected at the order level due to the compensatory responses of the underlying taxa. We conclude that the analyses of dark taxa can offer new insights into biodiversity responses to disturbances. Our results suggest considerable potential for forest management to foster arthropod diversity, for example by maintaining both closed‐canopy forests (>70% cover) and open forests (<30% cover) on the landscape.

Expression profiling of heat shock genes in a scuttle fly Megaselia scalaris (Diptera, Phoridae)

The Phoridae are a family of small, hump-backed flies, dominating in post-fire areas. Some of these flies are probably able to survive a fire as an egg, larva, or pupa, and may be adapted to the fire-altered environment at the genomic level. In this study, we describe the influence of short-term temperature treatment on the expression of seven heat shock protein genes in the third-instar larvae and imagoes of a scuttle fly Megaselia scalaris-one of the cosmopolitan and polyphagous phorids. In terms of the response to temperature treatment, these genes tested against tubulin as a reference split into three classes. The first class consists of hsp22 (larvae), hsp23 (larvae), and hsp26 (both larvae and imagoes), and is upregulated at the lowest temperature (33°C). The second class consists of hsp22 (imagoes), hsp23 (imagoes), hsp40 (larvae and imagoes), and hsp70 (larvae and imagoes), and is upregulated or induced at 37°C. Expression of genes of the third class (hsp27 and hsp83-larvae and imagoes) increased after treatment at 41°C temperature. Expression of the first two classes of genes occurred at a temperature lower than the LT of larvae and imagoes. The fact that there is a gap between the temperature upregulating hsp genes and the temperature leading to the loss of viability suggests that not only the level of hsp gene expression but also the temperature at which gene expression increased is important in an adaptation of M. scalaris to harsh environment.
