Targeted Sampling Increases Knowledge and Improves Estimates of Ant Species Richness in Rhode Island

چکیده
Only 0.7% of 28,205 known New England ant specimens (1861–2011) were from Rhode Island. Consequently, apparent ant species richness of Rhode Island counties was lower than expected based on simple biogeographic models. Collections from two poorly sampled areas—Block Island and Tiverton—and from the 2013 Rhode Island Natural History Survey’s BioBlitz increased Rhode Island’s ant specimens by 46% and its ant species richness from 48 to 57. Both Washington and Newport counties now have ant species richness more in line with New England-wide species-environment predictions. The extrapolated number of Rhode Island ant species is 66, but the upper bound of the 95% asymptote. Future collection efforts should continue to add ant species to the Rhode Island list, especially if collections are targeted in the state’s north and southeast regions, and its southwest pine barrens.

This study aimed to characterize production and reproduction performances in Rhode Island Red-White strain chicken developed and maintained at the Central Avian Research Institute, Izatnagar. Three hundred and forty six fertile eggs were set in automated electric incubation and 234 chicks were investigated in three hatches. The performance data was analyzed by least squares analysis of variance...
متن کاملAnt Diversity in Pitcher-plant Bogs of Massachusetts
We conducted the first systematic inventory of ant species richness in pitcher-plant bogs of Massachusetts. Twenty-six species were collected in 18 bogs during 1999 and 2000. We collected the bog-specialist Myrmica lobifrons for the first time in Massachusetts and found that it occurred in bogs from the Berkshire Mountains to Nantucket. Ant species composition in bogs displayed a nested subsets...

Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...
متن کاملThe Effects of Biogeography on Ant Diversity and Activity on the Boston Harbor Islands, Massachusetts, U.S.A
Many studies have examined how island biogeography affects diversity on the scale of island systems. In this study, we address how diversity varies over very short periods of time on individual islands. To do this, we compile an inventory of the ants living in the Boston Harbor Islands National Recreation Area, Boston, Massachusetts, USA using data from a five-year All Taxa Biodiversity Invento...

As part of an All Taxa Biodiversity Inventory in Boston Harbor Islands national park area, an inventory of carabid beetles on 13 islands was conducted. Intensive sampling on ten of the islands, using an assortment of passive traps and limited hand collecting, resulted in the capture of 6,194 specimens, comprising 128 species. Among these species were seven new state records for Massachusetts (A...
