We quant.fied microhabit.t.use by whit.-foot.d mice Peromyscus leucopus in forest.and old-field habit.t. occupied by Morrow＇ s honeysuckle Lonicera morrowii, an invasive exot.c shrub import.d from Japan. Microhabit.t.charact.rist.cs were compared bet.een t.ails used by mice （ n = 124） and randomly select.d t.ails （ n = 127） in 4 st.dy plot. locat.d at.Fort.Necessit. Nat.onal Bat.lefield, Farmingt.n, Pennsylvania, USA. We compared 10 mierohabit.t.variables bet.een used and random t.ails using non-met.ic mult.dimensional scaling （NMDS） and classificat.on and regression t.ee （CARt. analysis. t.ails used by mice were st.t.st.cally different.from randomly select.d t.ails in bot. forest.d plot. （ P 〈 0. 008） and old-field plot. （ P 〈 0. 001 ）. In t.e forest.d plot., t.ails of whit.-foot.d mice were more oft.n associat.d wit. a great.r percent.cover （% cover） of coarse woody debris （CWD） t.an were randomly select.d t.ails. In t.e old-field plot., mouse t.ails were commonly charact.rized by having a lower % cover of exot.c herbaceous veget.t.on, a great.r % cover of shrubs, and a great.r % cover of Morrow＇ s honeysuckle t.an randomly select.d t.ails. Our st.dy indicat.s t.at.whit.-foot.d mice do not.move randomly and prefer areas of high st.uct.ral complexit., t.ereby showing significant.microhabit.t.preference. t.e preference of whit.-foot.d mice for areas wit. a relat.vely high percent.cover of Morrow＇s honeysuckle could 1 ） be a fact.r in t.e aggressive nat.re of t.e exot.c honeysuckle shrub＇s spread t.roughout.t.e Bat.lefield or 2） cause t.e shrub t. spread even fast.r int. adjacent.areas not.yet.occupied by Morrow＇ s honeysuckle

Exot.c bush honeysuckles (Lonicera spp.) are becoming increasingly common in the eastern and mid-western United States, but little is known about their impacts on invertebrates. We used a modified leaf vacuum to sample invertebrates in the shrub strata and understory of three shrub types (and open plots in the understory): single Morrow’s honeysuckle (L. morrowii A. Gray) shrubs, single native southern arrowwood (Viburnum recognitum Fernald) shrubs, and dense thickets of Morrow’s honeysuckle, in southwestern PA, USA during 2004 and 2005. We also assessed the degree of herbivory on the two species of shrubs. Within the shrub strata, invertebrate biomass was lower in southern arrowwood shrubs, but there was no difference in invertebrate abundance or family richness. Invertebrate abundance and richness were lowest in August, but there was no difference in biomass among the months.

We used a mesocosm design t. compare t.e wat.r qualit. bet.een t.ree creat.d wet.ands and t.ree nat.ral wet.ands in West.Virginia, USA and t. evaluat. how t.e wat.r qualit. from t.e t.o wet.and t.pes were able t. support.met.morphosis in larval spring peepers (Pseudacris crucifer) and wood frogs (Lit.obat.s sylvat.cus) across t.o years (2014-2015). Responses in met.morphosis rat.s differed bet.een species and bet.een years. Spring peepers displayed similar met.morphosis rat.s in t.e creat.d and nat.ral wet.ands in bot. years of t.e st.dy. Wood frogs displayed similar met.morphosis rat.s in creat.d and nat.ral wet.ands in 2015, but.in 2014 wood frogs reached met.morphosis in less t.me and at.a larger body size in t.e nat.ral wet.ands, suggest.ng t.at.t.e wood frogs t.at.developed in t.e nat.ral wet.ands may have higher fit.ess t.an t.ose t.at.developed in t.e creat.d wet.ands. Wat.r qualit. was largely similar bet.een creat.d and nat.ral wet.ands, alt.ough dissolved oxygen, conduct.vit., and pH varied bet.een mesocosms and wet.ands. Our st.dy suggest. t.at.creat.d wet.ands may be providing part.al mit.gat.on in t.rms of wat.r qualit. for amphibian development. We recommend t.at.fut.re monit.ring of creat.d wet.ands include measures of juvenile amphibian recruit.ent.as well as addit.onal habit.t.variables t. bet.er det.rmine t.e abilit. of creat.d wet.ands t. funct.on as amphibian habit.t.

Const.uct.on of man-made object. such as roads and bridges can influence wildlife presence and abundance. We invest.igat.d wat.rbirds, songbirds, anurans, t.rt.es, small mammals, and furbearers along t.e Ohio River, WV, at.a new bridge crossing, a 45-year old bridge, and 1 or 2 islands wit. no bridge and at.3 dist.nces from t.e bridge or cent.r point.at.each sit. (0 m,100 m, and300 m). We sampled 19 wat.rbird, 60 songbird, 7 anuran, 5 t.rt.e, 9 small mammal, and 4 furbearer species. Great.blue heron (Ardea herodias) abundances were great.r at.t.e sit. wit. no bridge. Songbird composit.on differed among sit.s and bet.een t.ansect. under and away from t.e bridge wit. higher abundances or associat.on of rock pigeon (Columba livia) and cliff swallow (Pet.ochelidon pyrrhonot.) under t.e bridges and lower abundances ofCarolinawren (t.ryot.orus ludovicianus) and common yellowt.roat.(Geot.lypis t.ichas) under t.e bridges. t.t.l small mammal abundance, diversit., and richness were lower under t.e new bridge compared t. ot.er sit.s and dist.nces. We conclude t.at.overall t.e new bridge is causing minimal relat.ve abundance impact. t. wildlife. However, great.blue heron abundance may be alt.red due t. noise and act.vit. from t.e presence of t.e bridge and minor short.t.rm impact. t. some songbirds and small mammals direct.y under t.e bridge in t.e form of habit.t.conversion, fragment.t.on, and loss due t. removal of veget.t.on is apparent.

Global climat. change affect. many facet. of avian ecology, such as shift. in breeding phenology and migrat.on pat.erns. Migrat.ng bird species respond t. changes in climat. by shift.ng t.eir t.mporal pat.erns of spring migrat.on. However, variat.on in species’ responses exist. based on various life hist.ry t.ait., which exposes some species t. an increased risk of phenological mismat.h. t.is st.dy examined t.e spring arrival dat.s of 115 migrat.ng species over 127 years (1889-2015) using archival sources in West.Virginia, USA, making t.is research unique in t.e lengt. of st.dy, t.e high number of species st.died, and t.e hist.rical crowd-sourced observat.ons analyzed. Of t.e 115 t.xa, 45 showed significant.negat.ve slopes of spring arrival dat.s (arriving earlier in t.e spring) plot.ed against.t.e year. In cont.ast. only nine species showed posit.ve slopes (arriving lat.r in t.e spring), albeit.non-significant. t.e average advance of spring arrival dat. for all species was 1.7 days per decade, and an advance of 2.6 days per decade in species t.at.showed significance. Arrival dat.s were associat.d wit. increasing spring t.mperat.res—for each 1˚C increase, t.e arrival dat. advanced by 0.81 days/decade. Several life hist.ry t.ait. were linked t. species t.at.advanced t.eir first.arrival dat.s, including a short.r dist.nce migrat.d t. reach wint.ring grounds, increasing populat.ons, and foraging habit.t. Most.avian species are advancing t.eir spring arrival dat.s in response t. climat. change. However, t.e implicat.ons of earlier spring arrival are unclear. We draw at.ent.on t. shift. in arrival dat.s and wint.ring ranges, leading t. a possible increase in overwint.ring in t.e mid-lat.t.des of Nort. America.

t.e islands and associat.d back channels on t.e Ohio River, USA, are believed t. provide crit.cal habit.t.feat.res for several wildlife species. However, few st.dies have quant.t.t.vely evaluat.d habit.t.qualit. in t.ese areas. Our main object.ve was t. evaluat. t.e habit.t.qualit. of back and main channel areas for several species using habit.t.suit.bilit. index (HSI) models. t. t.st.t.e effect.veness of t.ese models, we at.empt.d t. relat. HSI scores and t.e variables measured for each model wit. measures of relat.ve abundance for t.e model species. t.e mean belt.d kingfisher (Ceryle alcyon) HSI was great.r on t.e main t.an back channel. However, t.e model failed t. predict.kingfisher abundance. t.e mean reproduct.on component.of t.e great.blue heron (Ardea herodias) HSI, t.t.l common muskrat.(Ondat.a zibet.icus) HSI, wint.r cover component.of t.e snapping t.rt.e (Chelydra serpent.na) HSI, and brood-rearing component.of t.e wood duck (Aix sponsa) HSI were all great.r on t.e back t.an main channel, and were posit.vely relat.d wit. t.e relat.ve abundance of each species. We found t.at.island back channels provide charact.rist.cs not.found elsewhere on t.e Ohio River and warrant.conservat.on as import.nt.riparian wildlife habit.t. t.e effect.veness of using HSI models t. predict.species abundance on t.e river was mixed. Modificat.ons t. several of t.e models are needed t. improve t.eir use on t.e Ohio River and, likely, ot.er large rivers.
