“…Further, many species of birds have been shown to be reluctant to cross habitat gaps and can be highly sensitive to forest fragmentation . Similarly, odonates show site fidelity and cases of extensive and restricted dispersal. Distance between patches may be more important for species less limited by their ability to cross unsuitable habitat, possibly even approaching Euclidean distance.…”

Maintaining and restoring connectivity are key adaptation strategies for biodiversity conservation under climate change. We present a novel combination of species distribution and connectivity modeling using current and future climate regimes to prioritize connections among populations of 26 rare species in New York's Hudson Valley. We modeled patches for each species for each time period and modeled potential connections among habitat patches by finding the least-cost path for every patch-to-patch connection. Finally, we aggregated these patches and paths to the tax parcel, commonly the primary unit of conservation action. Under future climate regimes, suitable habitat was predicted to contract or appear upslope and farther north. On average, predicted patches were nine times smaller and paths were twice as long under future climate. Parcels within the Hudson Highlands, Shawangunk Ridge, Catskill Mountains, and Harlem Valley had high species overlap, with areas upslope and northward increasing in importance over time. We envision that land managers and conservation planners can use these results to help prioritize parcel-level conservation and management and thus support biodiversity adaptation to climate change.

“…The use of models in studying social interactions can allow investigators finer control of experimental manipulations (Ferná ndez-Juricic et al 2006). Previous use of simple, painted models has shown that coloration in damselflies can be important in attraction to roosts (Grether & Switzer 2000), and Gorb (1998) clearly demonstrated the importance of color in sexual recognition by males. Now that we have shown odonates are similarly attracted to models for oviposition, future researchers could use models to examine aspects of conspecific attraction that are not readily approachable otherwise.…”

Finding a suitable oviposition site can be costly because of energy and time requirements, and ovipositioning can be dangerous because of the risk of predation and harassment by males. The damselfly Argia moesta oviposits, contact‐guarded by her mate, on vegetation in streams. Oviposition aggregations are commonly observed in this species, despite their territorial nature during other behaviors. We conducted experiments in the field to test the hypothesis that aggregations are the result of conspecific attraction. In the first experiment, two oviposition sites (sycamore leaves) were provided, one with models of ovipositing pairs, and one without. In the second experiment, one leaf again had ovipositing models, while the other had models of uncoupled males and females in a resting posture. In both experiments, damselfly pairs preferred the site with ovipositing models. In general, they visited the ovipositing models first more often than expected by chance, stayed longer there, were more likely to oviposit there, and laid a greater total number of eggs there. These results support the hypothesis that conspecific attraction is responsible for ovipositing aggregations in A. moesta and that posture is an important cue for attraction. Using conspecific cues could be a beneficial strategy to save in search costs while taking advantage of the presence of ovipositing conspecifics to dilute the effects of harassment and predation.

“…Many animal species aggregate during periods of inactivity, a behavior pattern referred to as communal roosting (Beauchamp, ; Bijleveld, Egas, van Gils, & Piersma, ; Laughlin, Sheldon, Winkler, & Taylor, ). Communal roosts have been studied in primates (Anderson, , ; Ansorge, Hammerschmidt, & Todt, ), bats (Foster & Kurta, ), birds (Beauchamp, ; Eiserer, ), insects (Devries, Schull, & Greig, ; Finkbeiner, Briscoe, & Reed, ; Grether & Switzer, ) and arachnids (Pereira, Elpino‐Campos, Del‐Claro, & Machado, ; Wade, Loaiza‐Phillips, Townsend, & Proud, ).…”
