The reproductive success of American kestrels (Falco sparverius) infected with Trichinella pseudospiralis was significantly reduced when compared with uninfected controls. Egg laying was delayed, and infected females produced fewer eggs than uninfected controls. Infected females were more aggressive and copulated less frequently. Egg breakage among infected birds was greater than among controls. Infected females tended to lay eggs outside the nest box. Infected females did not incubate as frequently as the controls, thus accounting for the higher prevalence of embryo mortality among these birds. The above effects translated into a mean production of 2.1 hatchlings per control pair and 0.6 per infected pair of kestrel. Both in breeding and non-breeding kestrel, T. pseudospiralis infections gave rise to a general decline in mobility. Behavioural effects are primarily attributable to the presence of muscle larvae. The parasite showed no predilection for specific muscle groups.

<p> The Sunken Forest, located on Fire Island National Seashore, is a critically imperiled habitat and is one of only two known old-growth maritime holly forests in the world. Analysis of a dataset that dates back to nearly half a century has helped to identify major drivers influencing changes within the forest. These major drivers include; white-tailed deer herbivory, erosion, sea level rise, increased storm events, and canopy-gap dynamics. As of 2013, the Sunken Forest canopy is still analogues of 1967, but over the last 35 years vegetation recruitment within the forest has become limited due to white-tailed deer (<i>Odocoileus virginianus</i>) herbivory. The bayside of the Sunken Forest has also been eroding. Erosion with added pressure from sea-level rise is causing mortality of trees/understory vegetation, limiting seedling and herb recruitment, and shifting vegetation toward the bayside and low elevation areas within the interior of the forest.</p>
