Resumen
Phlomis fruticosa is a weakly lignified shrub which colonizes large expanses in Albania and Greece in overgrazed areas, and is also present throughout the northern Mediterranean region from Italy to Cyprus. It is characteristic for species-rich vegetation, with up to 65 species on 50 m2. We assembled a dataset of 129 original and published relevés and analyzed the floristic variability and the ecology of vegetation containing Phlomis fruticosa in the central Mediterranean region. We floristically and ecologically differentiated three previously described associations: a) the Salvio fruticosae-Phlomidetum fruticosae, distributed in Sicily, is characterized by high species richness of nano-phanerophytes, and is restricted to the warmest and more oceanic part of the range of P. fruticosa; b) the Sideritido italicae-Phlomidetum fruticosae is characterized by high chamaephyte richness, and occurs in cooler, relatively oceanic areas; c) the Allio pulchelli-Phlomidetum fruticosae is very rich in therophytic species and occupies the drier, more continental part of the distribution area of P. fruticosa. The vegetation syntaxa of the P. fruticosa scrubland belong to two structural types: a relatively low scrubland with a poorly developed herb layer on limestone boulders, and a taller, more open scrubland with a rich herb layer that grows in pastures and abandoned fields. Our results suggest that scree and boulders is the primary habitat of low-growing P. fruticosa scrublands (first structural type), from which the species colonized overgrazed areas and abandoned fields, after humans cleared the primeval Mediterranean forest.

Resumen
Abstract Organic carbon in soil can be utilized to assess soil quality and aid to climate change mitigation. Soil organic carbon stock assessment in West Sumatra is still limited. This research focused on soil organic carbon stock distribution in various land-uses in Duku, Koto XI Tarusan, Pesisir Selatan Regency. Research area included secondary forest, scrubland, paddy field, and dryland agriculture. Soil samples were obtained by stratified sampling. Samples were taken at depths of 0-30 and 30-60 cm from each land-use type with the same slope and soil type. A soil unit polygon was randomly selected for sampling. 21 samples were collected and analyzed for bulk density, texture, soil respiration, total nitrogen content, and organic carbon. Secondary forest had the highest soil organic carbon storage (128.82 - 294.09 tons per hectare), followed by paddy fields (16.99 - 227.14 tons per hectare), dryland agriculture (10.40 - 65.43 tons per hectare), and scrubland (13.39 - 53.19 tons per hectare). Nitrogen content was higher in secondary forest>paddy soil>scrubland>dry land. Bulk density was found to be higher in scrubland than in dry land, paddy soils, and secondary forest. Soil pH was greater in paddy soil>scrubland>dryland>forest.

Resumen
Ecosystems provide various environmental services such as key recharge and ow of the water resource, but they can be damaged by human activity. Understanding vegetation cover allows administrators to predict the effects of such changes on groundwater and the actions needed in ad- ministration. Grecia Forest Reserve is a 2000-hectare zone in Costa Rica that affects eleven settlements in the region. There we measured vegetation cover and water volume in all water springs (N=70). We identified four vegetation groups: secondary forest, scrubland, pasture and pine forest; and an overall mean ow of 1,12 l/s/ha. Most water springs were found in secondary forest, which had the highest vegetation cover; however, scrublands had higher flows.

Resumen
Understanding the relation of agroecosystem types, ages, and soil properties are vital in maintaining good quality soil. This study aims to explore the variation of selected soil properties with agroecosystem types and ages. The research has been conducted in North Bengkulu, Indonesia. Soil properties on agroecosystems of 5-yr, 10-yr, 15-yr oil palm plantation, 5-yr, 10-yr, 15-yr rubber plantation, food cropland, and scrubland were evaluated. The study found that soil in oil palm and rubber plantations of any age have a similar texture, bulk density (BD), and actual soil moisture (ASM). All plantation agroecosystems and scrubland have higher clay and lower silt content than that in food cropland. In addition, the scrubland has the highest ASM content among the agroecosystems. On the other hand, both agroecosystems enhances soil chemical properties than food cropland and scrubland as indicated by the improvement of organic-C, total-N, available P, exchangeable K and CEC of Ultisols. Older plantation also provides higher soil chemical improvement than younger one. This finding is significant for management of sub optimal soil mainly Ultisols for oil palm and rubber plantation.

Resumen
Environmental factors determining the presence of the Carbonell lizard Podarcis carbonelli (Pérez-Mellado, 1981) in the Doñana area The Carbonell lizard (Podarcis carbonelli) is an Iberian endemism. The region of Doñana is its southernmost and more isolated stronghold. We used logistic regressions to investigate the factors conditioning the presence of this lizard in Doñana. All selected models retained the distance to the coast as the main variable. This variable is related with less humidity and more continental climatic conditions, including more extreme temperatures, when further from the coast. This climatic factor was observed both spatially and temporarily, with adult lizards drastically reducing their activity both in winter and in summer. We observed juveniles from June to January, with a maximum in September. Scrubland management was another important environmental factor affecting the presence of lizards. The probability of finding this species was higher where the scrubland was partially cleared, and lower in areas with a high plant cover (hygrophytic scrubland) or in areas with sparse vegetation (dune scrubland), probably due to a lower amount of incident light and less protection when moving between refuges, respectively.

Resumen
Sierra Rica is a mountain island located in the plains of the northeastern region of the Chihuahua Desert and has a diversity of vegetation patterns. To study this patterns the vegetation was characterized using GIS and cluster analysis, which identified five community types: pine forest (780 ha), oak forest (1640 ha), grassland (550 ha), desert scrub (866 ha), and rosetophyllous desert scrubland (628 ha). By the use of TWINSPAN software, four main vegetation groups containing 10 main plant associations were identified: (1) Pinus-Quercus forest, (2) grassland, (3) pine forest, (4) Rhus-Juniperus, (5) Pinus-Quercus and xeric species, (6) grassland-desert scrub, (7) desert microphyll scrub, (8) Quercus-Aloysia-Bouteloua association, (9) Acacia constricta scrubland, and (10) Larrea tridentata scrubland. The association among groups and species was significant (P < 0.0001). The subsequent analysis shows a high dependence among species inside the main groups and independence between groups.

Resumen
Wildfires are important sources of landscape change in Mediterranean environments, creating large patches of low-growth natural habitats (i.e., scrublands) inside protected areas, whereas woodland patches remain mostly near well protected human settlements. Landscape patterns resulting from these gradients influence habitat suitability for mesocarnivores regarding food and shelter. In winter and summer 2019, we sampled 16 independent line-transects with four camera traps each (64 cameras overall), covering the main habitats of the study area (woodlands, scrublands, and crops). Cameras were baited to compensate for the low detectability of target species, and mesocarnivore contacts were analysed by means of GLMMs and occupancy models. Our results showed a positive and stronger association of wild species with woodland habitats, despite the low proportion of habitat available, higher presence of competitors (other mesocarnivores), and potential predators (human pets, i.e., dogs), and low natural prey availability than in scrubland (i.e., small mammals). However, mesocarnivores will find protection against predators and resting sites in forests as well as other food opportunities in crops and urban areas, despite the possible interference with humans and their pets. Potential cascading effects linked to ecological roles of Mediterranean mesocarnivores on the succession of Mediterranean landscapes would imply longer-term effects of human disturbance on landscape trends.

Abstract. Glacial-interglacial fluctuations in the vegetation of South Africa might elucidate the climate system at the edge of the tropics between the Indian and Atlantic Oceans. However, vegetation records covering a full glacial cycle have only been published from the eastern South Atlantic. We present a pollen record of the marine core MD96-2048 retrieved by the Marion Dufresne from the Indian Ocean ∼120 km south of the Limpopo River mouth. The sedimentation at the site is slow and continuous. The upper 6 m (spanning the past 342 Ka) have been analysed for pollen and spores at millennial resolution. The terrestrial pollen assemblages indicate that during interglacials, the vegetation of eastern South Africa and southern Mozambique largely consisted of evergreen and deciduous forests. During glacials open mountainous scrubland dominated. Montane forest with Podocarpus extended during humid periods was favoured by strong local insolation. Correlation with the sea surface temperature record of the same core indicates that the extension of mountainous scrubland primarily depends on sea surface temperatures of the Agulhas Current. Our record corroborates terrestrial evidence of the extension of open mountainous scrubland (including fynbos-like species of the high-altitude Grassland biome) for the last glacial as well as for other glacial periods of the past 300 Ka.

Resumen
An abandoned sphalerite mining area in the southwest (SW) of the Iberian Peninsula was studied to evaluate the impact that the presence of metal(loid)s has on soil and ecosystem health. Five zones were delimited: sludge, dump, scrubland, riparian zone, and dehesa. Critical total levels of lead (Pb), zinc (Zn), thallium (Tl), and chromium (Cr), well above the limit indicative of toxicity problems, were found in the areas close to the sources of contamination. Pb-Zn concentrations were very high in the riparian zone, reaching values of 5875 mg/kg Pb and 4570 mg/kg Zn. The whole area is classifiable as extremely contaminated with Tl, with concentrations above 370 mg/kg in the scrubland. Cr accumulation mainly occurred in areas away from the dump, with levels up to 240 mg/kg in the dehesa. In the study area, several plants were found growing luxuriantly despite the contamination. The measured metal(loid)s content is the cause of a significant decrease in ecosystem services, resulting in unsafe soils for food and water production, so the implementation of a decontamination program is advisable. The plant species Retama sphaerocarpa, present in the sludge, scrubland, riparian zone, and dehesa, is postulated as suitable for use in phytoremediation.

Resumen
The distribution range of Spectacled Bear in Ecuador has been strongly fragmented owing to human activities, thus studying the conservation status of the remaining patches in which this species inhabits is essential to ensure its conservation. We performed a descriptive analysis of the conservation status of the ecosystems that form part of the Spectacled Bear distribution range in Ecuador, using values of five indicators (fragmentation, connectivity, threat, vulnerability and fragility) provided by the Ecuadorian Ministry of Environment. Moreover, we compared the conservation status between scrubland & pastures and evergreen forest ecosystem according to the five indicators. Overall, the Spectacled Bear distribution in Ecuador is covered by a greater surface area of ecosystems classified with a medium level of fragmentation (58.8%), low connectivity (45.1%), high fragility (45.6%), high (38.2%) and medium threat (39.2%), as well as high (33.7%) and medium (33.1 %) vulnerability. Scrubland and pastures ecosystems had worse conservation status than evergreen forests, with 98% of their surface classified as having low or very low connectivity, 77.3% as high fragility and 77.4% as high threat. These results showed the worrisome conservation status of the ecosystems shaping the distribution range of Spectacled Bear in Ecuador, particularly the scrubland and pastures, and therefore, a wider national strategy (inside and outside the limits of the bear distribution range) should be applied to ensure the preservation of these ecosystems.

Resumen
Habitat preferences of wildcats are controversial. Although they are usually considered a forest species, alternative environments such as scrubland can be preferred. In this study we compared five habitat types in relation to wildcat occurrence. Sampling was carried out between 2001 and 2002 on a series of transects in search of wildcat scats to calculate an abundance index. Structural variables of landscape and rabbit abundance were also estimated and summarised as orthogonal factors using a principal component analysis (PCA). A priori contrasts showed that wildcats tended to be more abundant in areas with Mediterranean mountain vegetation, although agricultural steppes also provided suitable habitat. The forest variables were not included in the general linear model (GLM) obtained, indicating that wildcats are mainly associated with scrubland mosaics with rabbits in this region.

Resumen
Scrubland clearcutting forms one of main management techniques conducted in the Doñana National Park, and has the aim of creating open areas where rabbits can feed, as these animals are the basic prey of lynx and imperial eagle. This management measure has produced a deep change in scrubland structure, without its effect on other species characteristic of this habitat, such as small mammals, remains unknown. This study evaluated shrub removal by controlled burning on the micromammal community, and analysed its richness and temporal evolution in different environments. The study was conducted from the summer of 2006 to spring of 2007 using a capture-mark-recapture approach in 6 controlled burning plots (3 recents and 3 four years old) and in 3 control plots which were left untreated. Species richness was quite low, with only 4 species captured: Algerian mouse (Mus spretus), Wood Mouse (Apodemus sylvaticus), Greater white-toothed shrew (Crocidura russula) and Garden dormouse (Eliomys quercinus). Abundance values were highly varied depending on the species, time of year and plot type. However, the most abundant species by far was Mus spretus. The comparison of the results obtained in the managed plots respect to the control ones, suggest that burning of scrub is a management technique that favours not only rabbit populations but also small mammals community, mainly due to edge effect caused by fire. The scrubland clearcutting would have to be realised of rotatory form and favoring the creation of zones of contact between both habitats.

Resumen
The Lower Gangetic Basin is one of the most highly populated areas of India, covering an area of 286,899 km<sup>2</sup> with a population density of 720 persons per km<sup>2</sup>. 64 % of the area is covered under agriculture which is supported by the highly fertile alluvial soil. Landuse and landcover (LULC) changes due to an ever increasing human population, natural disasters induced by climate change can alter agricultural productivity which in turn can affect the food security of the region. The current study found out the change in LULC over a span of 20 years (1985&ndash;2005), and identified the factors driving this change. LULC data was generated from geo-corrected satellite data of LANDSAT-MSS, IRS LISS-I and IRS LISS-III for pre monsoon and post monsoon seasons for the years 1985&ndash;86, 1994&ndash;95 and 2004&ndash;05 respectively, using onscreen visual interpretation at 1 : 250,000 scale. We used cross-tabulation matrix to investigate landuse and landcover transformation. The most significant transformation has been to built-up category, contributed by agricultural land (515 km<sup>2</sup>) and scrubland (53 km<sup>2</sup>). The other notable transformations are from agriculture to plantation (247 km<sup>2</sup>), fallow to scrubland (838 km<sup>2</sup>) and from water body to scrubland (407 km<sup>2</sup>). We generated change no-change matrix and analyzed it using logistic regression to investigate the drivers of LULC change. We identified availability of water for irrigation, literacy, sexratio and the availability of different sources of livelihoods, as the major drivers of LULC change in the Lower Gangetic Basin.

Resumen
This study investigated grazing capacities of maquis scrubland and preparation principles of grazing management in forest resources. Kermes oak (Quercus cocciferaL.), which is widespread as a main shrub species in maquis vegetation in Turkey, and pure hair goats (Capra hircusL.) feeding on shoots and leaves of this shrub were selected for study. The study was conducted in two stages. Green leaf and shoot samples were taken from kermes oaks in the first stage and the amount of green herbage yield (g*m−1) and dry matter yield (kg*ha−1) that may be obtained per unit area from these samples was identified. The considered amount of dry matter consumed by pure hair goats daily and the number of goats being fed within 1 year on land of 1 ha according to different land coverage rates of kermes oaks (goat head*ha*yr) were calculated. In the second stage, grazing capacities of sample areas where kermes oak spread were identified and compared with the grazing plan prepared by the forestry administration for this area. Forage yield variance according to land coverage rates of maquis scrublands should be considered when determining optimum animal numbers for grazing per area for sustainable goat farming.

Resumen
Healthy natural forests maintain and/or enhances carbon stock while also providing potential habitat and an array of services to wildlife including large carnivores such as the tiger. This study is the first of its kind in assessing relationships between above-ground biomass carbon stock, tiger density and occupancy probability and its status in protected areas, corridors, and forest connectivity blocks. The dataset used to assess the relationship were: (1) Converged posterior tiger density estimates from camera trap data derived from Bayesian- Spatially Explicit Capture-Recapture model from Chitwan National Park; (2) Site wise probability of tiger occupancy estimated across the Terai Arc Landscape and (3) Habitat wise above-ground biomass carbon stock estimated across the Terai Arc Landscape. Carbon stock maps were derived based on eight habitat classes and conservation units linking satellite (Landsat 7 ETM+) images and field collected sampling data. A significant negative relationship (r = -0.20, p<0.01) was observed between above-ground biomass carbon stock and tiger density in Chitwan National Park and with tiger occupancy (r = -0.24, p = 0.023) in the landscape. Within protected areas, we found highest mean above-ground biomass carbon stock in high density mixed forest (~223 tC/ha) and low in degraded scrubland (~73.2 tC/ha). Similarly, we found: (1) highest tiger density ~ 0.06 individuals per 0.33 km2 in the riverine forest and lowest estimates (~0.00) in degraded scrubland; and (2) predictive tiger density of 0.0135 individuals per 0.33 km2 is equivalent to mean total of 43.7 tC/ha in Chitwan National Park. Comparatively, we found similar above-ground biomass carbon stock among corridors, large forest connectivity blocks (~117 tC/ha), and within in tiger bearing protected areas (~119 tC/ha). Carbon conservation through forest restoration particularly in riverine habitats (forest and grassland) and low transitional state forests (degraded scrubland) provides immense opportunities to generate win-win solutions, sequester more carbon and maintain habitat integrity for tigers and other large predators.

Resumen
Biodiversity loss occurring in mountain ecosystems calls for integrative approaches to improve monitoring processes in the face of human-induced changes. With a combination of vegetation and remotely-sensed time series data, we quantitatively identify the responses of land-cover types and their associated vegetation between 1987 and 2016. Fuzzy clustering of 11 Landsat images was used to identify main land-cover types. Vegetation belts corresponding to such land-cover types were identified by using species indicator analysis performed on 80 vegetation plots. A post-classification evaluation of trends, magnitude, and elevational shifts was done using fuzzy membership values as a proxy of the occupied surfaces by land-cover types. Our findings show that forests and scrublands expanded upward as much as the glacier retreated, i.e., by 24% and 23% since 1987, respectively. While lower alpine grassland shifted upward, the upper alpine grassland lost 10% of its originally occupied surface showing no elevational shift. Moreover, an increase of suitable sites for the expansion of the subnival vegetation belt has been observed, due to the increasing availability of new ice-free areas. The consistent findings suggest a general expansion of forest and scrubland to the detriment of alpine grasslands, which in turn are shifting upwards or declining in area. In conclusion, alpine grasslands need urgent and appropriate monitoring processes ranging from the species to the landscape level that integrates remotely-sensed and field data.

Resumen
The historical formation of holm oak (Quercus ilex L.) dehesa woodlands has often resulted in either rapid deforestation episodes by means of clear cuts or slower depletion of oak woodlands due to tree natural mortality and the absence of tree natural regeneration. Consequently, holm oak woodlands have been progressively converted into rough pasturelands, cereal croplands and scrublands. Whilst this tendency of holm oak exhaustion was not socially questioned, scientists and conservationists defending oak woodland conservation providing long run economic and environmental arguments were regarded as romantics ignoring the necessity for social progress and development. Today, these romantics are perceived as nature conservation pioneers and many of their arguments and concepts have been included in science and politics. This paper shows that cereal cropping and permanent grassland uses are more profitable to Extremadura’s landowners than holm oak artificial plantations and monitored holm oak natural regeneration. Increasing social demand for recreational and conservation services have been taken into account by Spanish and European public authorities. Along last decade, the European Union and the Spanish government have financed oak reforestation over extensive-use croplands of West and Southwest Spain, resulting in an unprecedented net increase in holm oak woodlands. The presented extended cost-benefit analysis shows that even after incorporating estimated income derived from public and private consumption of environmental services, uses associated to treeless cropland, pastureland and scrubland are still preferred to traditional extensive multiple use associated to dehesa holm oak woodlands.

Resumen
Land-use change is the main driver of biodiversity loss in the Mediterranean basin. New socio-economic conditions produced a rewilding process so that cultural landscapes are being invaded by more natural habitats. We analyze the effects of landscape change on the demography and the spatial distribution of Crocidura russula in six protected areas of the western Mediterranean basin. The study was conducted in the period 2008–2020 on 19 live trapping plots representing the three main natural habitats of the area (scrubland, pinewood, and holm oak woodland). We used a multiscale approach to ensure that the scale of response matched landscape structure (from plot to landscape) using either vegetation profiles (LiDAR) and land use data obtained from years 2007 and 2017. Statistical models (multiple-season single-species occupancy models) showed that C. russula populations were strongly associated to habitat features at the plot level. These models were used to predict occupancy at sampling units for the whole study area (850 km2), showing contrasting trends that shifted at relatively small spatial scales (expansions and retractions of species ranges). Parks showing extreme scrubland encroachment (−8% of area) and afforestation (+6%) significantly reduced habitat suitability for shrews and reductions in occupancy (−5%). Results would indicate faster changes in the spatial distribution of the target species than previously expected on the basis of climate change, driven by fast landscape changes.

Resumen
This research deals with the taxonomy, geographical and ecological distribution, and the forms of utilization and available empirical knowledge of Agave spp., subgenus Agave, in San Luis Potosí and Zacatecas. The following taxa were found: wild species: Agave salmiana ssp. crassispina, A. scabra ssp. potosiensis, A. parrasana; semicultivated species: A. americana var. oaxacensis; cultivated species: A. mapisaga var. mapisaga, three forms of A. salmiana var. salmiana. A. salmiana ssp. crassispina is the most widely distributed and abundant. It is found from 1 800 to 2 400 m altitude, on igneous and sedimentary substrates, euthric Litosol, and it is an element of the cactus and desert scrubland. It is used to produce mezcal and for the preparation of the edible flowering stem (quiote) . It is the Agave most used as forage, and it is also utilized as construction material, as fuel, in soil conservation, as ornament and as hedge plant. A. mapisaga var. mapisaga and A . salmiana var. salmiana are cultivated principally to the NNW of the city of San Luis Potosí, at 1 880 m, on a deteriorated cactus scrubland. Aguamiel, pulque and honey are elaborated from the natural or fermented juice extracted from the meristem of the plant. There is considerable amount of empirical knowledge regarding the management of this resource. However due to several problems its current use is reduced.

Resumen
Abstract Elk Cervus elaphus are rare in Southwestern desert grassland and desert-scrub habitats, and these habitats are anecdotally considered unsuitable for elk. We studied a colonizing herd in a Southwestern desert grassland–scrubland in northwestern New Mexico to determine the condition and population dynamics of elk in this habitat type. We radiotracked ≤ 24 adult (1.5 y and older) cows and ≤ 8 calves annually, 2003–2006; the sample of radiocollared cows in this study was very close to a census of the entire population for 2004–2006 based on repeated surveys and monitoring. Mean body fat of lactating cows in autumn was 10.6–13.2% in 2003–2004, indicating that lactating elk were acquiring high moderate–low good nutrition, but dropped to 5.6% in 2005 and 6.8% in 2006, indicating poor nutrition for these years of low precipitation. We found adult female survival of 0.94–1.00 and calf survival of 0.38–1.00. Calf survival was related to maternal size, maternal condition, and cumulative annual precipitation through parturition; all calf mortality occurred at or near parturition. Pregnancy rates averaged 0.33 for yearling cows and 0.86 for ≥ 2.5-y-olds, 2003–2006, and pregnancy was positively related to body mass for ≥ 2.5-y-old adults. Lactation rates of ≥ 2.5-y-olds averaged 0.59, 2003–2005, but dropped to 0.30 in 2006, due to poor maternal condition and low precipitation. Since colonization, elk have increased from about 20 to ≥ 53 individuals, a mean rate of increase of 18%/y prior to 2006, but decreasing to ≤ 4% in 2006. The high sustained rate of increase (with few exceptions) indicates that desert grassland–scrubland habitats are suitable for elk and merit consideration in elk management plans of Southwestern agencies.

Resumen
Reversion of agricultural land to native woody vegetation can sequester carbon (C), influencing regional and global C budgets. We examined whole-ecosystem differences in C and nitrogen (N) storage and distribution, and sapwood - leaf area relationships in a scrubland vegetation chronosequence in New Zealand dominated by manuka (Leptospermum scoparium J.R. et G. Forst) and kanuka (Kunzea ericoides var. ericoides (A. Rich.) J. Thompson). At 25 years, manuka dominated, and vegetation C was 6.5 kg C·m-2. In the 55-year-old stand, stem density was similar for the two species, and vegetation C storage was 15.1 kg C·m-2, similar to the 35-year-old stand (p = 0.9). Foliar biomass comprised 3-5% of vegetation C stock but contained 26%-37% of vegetation N. Root biomass was 10-15% of total and varied little with stand age. The sapwood - leaf area relationship differed significantly for the two species (p < 0.05). Mineral soil C and N (to 0.30 m) did not vary with stand age, but forest floor C and N were highest in the 55-year-old stand (2 kg C·m-2; p < 0.01). Soil and forest floor C/N ratios were significantly higher in the 35-year-old stand (p < 0.04), possibly because of high interspecific competition for N. While the sampling intensity was too limited to allow spatial extrapolation, our results suggest that carbon accumulation in this scrubland is rapid and similar to plantation forests, suggesting that land abandonment could significantly impact New Zealand's C budget.

This study reports the occurrence of the ant cricket Myrmecophilus orientalis Stalling, 2010 on the Dodecanese Islands Kos and Tilos, Greece. This is the first evidence of M. orientalis from Greece and Europe. The species lives in ant nests under stones and in dead wood in open scrubland and pine forests. The adults were found in the nests of large Camponotus species, while the juveniles were found in the nests of small ant species of the genera Crematogaster and Lepisiota. We assumed that the species changes the host ant species during its life cycle.
