“…Ant-trap frequency can be used to reduce potential overestimation of social insects inherent in worker abundance (Andersen, 1991;Gotelli et al, 2011). T. ambiguus nests in hollow stems and has been cited multiple times in remnants (Gregg, 1944;Hill & Brown, 2010;Nemec, 2014), and P. tysoni, a seed harvester, is common in southern tall grass prairie remnants (Hill & Brown, 2010). Some large bodied Formica ants can travel up to 20 m from their nests (Schlick-Steiner et al, 2006), but typically, grassland ants travel no more than 2 m (Albrecht & Gotelli, 2001;Schlick-Steiner et al, 2006).…”

“…T. sessile was more frequent in young sites, disturbed by intensive agriculture, while T. caespitum frequency was determined by sandy soil reducing the signal of any urbanisation effects. T. ambiguus is a known prairie associate (Gregg, 1944;Hill & Brown, 2010;Nemec, 2014) and may be a potential indicator of grassland recovery from disturbance at the landscape and patch levels. While both of these species are common in human-dominated habitats, they have also been detected in remnant prairies.…”

“…For example, several uncommon or rare species in our grasslands have previously been documented in remnants (Gregg, 1944;Hill & Brown, 2010), but were collected too infrequently for analysis: Temnothorax pergandei, Pheidole pilifera, Crematogaster lineolata and Formica integra. Most of the historical prairies were located in central and northern Ohio.…”

Agri‐environmental incentive programmes encourage conversion of marginal agricultural land to grasslands to reduce soil erosion and support biodiversity of native flora and fauna. Most grassland animals colonise these constructed habitats as propagules from the surrounding landscape. Ants are slow to colonise and rely on resources within the patch, making them valuable as indicators of disturbance and recovery. We studied how ant species diversity and composition are structured by patch and landscape variation of grasslands in Ohio, USA. Ant communities were collected from 23 constructed grasslands differing in area, age, vegetation, soils, management and surrounding land cover. We analysed trap frequency for 14 species that varied in habitat specialisation to identify species responses to patch‐ and landscape‐level predictors. Grassland age and soil texture determined ant species richness and community composition. Trap frequency analysis showed contrasting species responses to patch and landscape characteristics: habitat specialists were more abundant in older, larger patches with more surrounding grassland, while disturbance‐tolerant species were more frequent in younger patches surrounded by intensive agriculture. Habitat generalists and open habitat species included a variety of patch‐ and landscape‐level factors in best models. Ant community assembly in constructed grasslands is shaped by time and physical characteristics at the patch‐level, but the surrounding landscape acts as a filter for the colonising community. Our findings support the use of ants as ecosystem recovery indicators following disturbance in agricultural landscapes, but show that shifts in species composition are better indicators of grassland habitat variation than ant richness.

“…Across its range, the ant excavates its nests under plants with fibrous roots Johnson 1989), including blackberry Rubus spp. (Talbot 1956), cattails Typha spp (Gregg 1944; Kannowski 1956), and grasses (Wheeler 1905; Cole 1940). …”

Dolichoderus mariae Forel, (Hymenoptera: Formicidae) is an uncommon, monomorphic but locally abundant, reddish-brown ant of peculiar nesting habits, whose range includes most of the eastern USA. In north Florida the ant excavates soil under wiregrass clumps or other plants with fibrous roots to form a single, large, shallow, conical or ovoid chamber broadly open to the surface around the plant base. Colonies are highly polygyne and, during the warm season, inhabit multiple nests connected only by above ground trails, over which nests exchange workers. Although monomorphic, worker size may differ significantly between colonies. The colony cycle is dominated by strong seasonal polydomy. From one or two over-wintering nests, the colonies expanded to occupy up to 60 nests by late summer, then retract once more to one or two nests by mid-winter. The worker-to-queen ratio changed greatly during this cycle, with over two thousand workers per queen during fall and winter, dropping to a low of about 300 during midsummer. Most of these summer queens probably die during the fall. Colonies reoccupy roughly the same area year to year even though they contract down to one or two nests in winter. Observation of fights in the contact zone between colonies suggested that the colonies are territorial. The ants subsist by tending aphids and scale insects for honeydew and scavenging for dead insects within their territories.

“…Ecological surveys of ants have dealt primarily with natural communities and successional stages, or have examined the role of ants in cultivated fields (Carter, 1962a;Cole, 1934Cole, , 1940Dennis, 1938;Gregg, 1944;Hayashida, 1960;Hess, 1958;Kannowski, 1956;Letendre and Pilon, 1973;Talbot, 1934Talbot, , 1953Van Pelt, 1956, 1963Whitcomb et al, 1972). In North Carolina, several lists of species (Brimley, 1938;Wheeler, 1904;Wray, 1967) and a comprehensive survey among the major physiographic regions and selected plant communities (Carter, 1962a(Carter, , 1962b have been published.…”
