The high diversity and endemism of cloud forests make them good models to explore the impacts of habitat disturbance on bat communities and their ectoparasites. Although bat responses to forest disturbance have been intensively studied, the response of their ectoparasites in cloud forests remains poorly known. We explore this knowledge gap by analy...
Article
Sit-and-wait is a common strategy to optimize time and energy devoted to foraging activities. Among Coleoptera, dung beetles are one of the groups that display this behavior. Although diverse aspects of natural history have been reviewed, no agreement exists on which theory may explain this food searching tactic. We performed a systematic literatur...

Mesoamerican cloud forests support diverse bat communities, but remain poorly studied. Here, we provide an overview of the bat community of Cusuco National Park (CNP), Honduras, an area of tropical cloud forest and adjacent lowland habitats. Our results are based on one of the longest-running bat surveys completed regionally to date. Mist nets were...

1. Many animals invest a great amount of time and energy foraging. However, the sit‐and‐wait strategy is a common behaviour, which reduces the cost of moving by using perches. In the case of dung beetles, individuals of many species use leaves as perches. The factors for the selection of these perches are still unknown, but one hypothesis proposes...

For arboreal primates, ground use may increase dispersal opportunities, tolerance to habitat change, access to ground-based resources, and resilience to human disturbances, and so has conservation implications. We collated published and unpublished data from 86 studies across 65 localities to assess titi monkey (Callicebinae) terrestriality. We exa...

Stable-isotope analysis can address fundamental questions about the ecology and life history of mobile organisms. The hydrogen isotope, deuterium (δ 2 H), follows distinct and predictable patterns along environmental gradients, enabling migratory-origin assignments in vagile animals such as bats. However, it is unclear to what degree deuterium leve...

This note reports the first record of Micronycteris sanborni in Amazonas State, Brazil. It extends the species ' known range > 2000 km northwestward and represents the first record of M. sanborni in a humid tropical ecosys-tem, suggesting that the species might not be exclusive to dry areas, as previously thought. The individual was captured in Vis...

Bats vary their activity with different features of habitat, resource availability, predation risk, and other factors. Agricultural fi elds may provide an abundance of insect prey, but are also risky habitats due to their exposure. How bats use mixed landscapes is im-portant information for biologists, as increasing development affects the amount o...
Conference Paper
Background/Question/Methods Stable hydrogen isotope analysis is a method that is being increasingly used to determine geographic origin and trace the movement of bats. The heavy hydrogen stable isotope has a defined gradient across the globe and can be used as a geographic tracer because it is metabolically incorporated into the fur of the bat. St...
Conference Paper
Background/Question/Methods Habitat destruction is one of the biggest threats to biodiversity and therefore habitat preservation is a top conservation priority. Ecosystems may be drastically changed with the loss of just one species. Bats in Northeastern United States are key components of an ecosystem serving as biological pest controls and indi...

Full-text available
Background/Question/Methods The future of tropical forest species depends in part on their ability to survive in human-modified landscapes. Theory suggests that species with particular traits may be greater risk of extinction as a consequence of habitat modification than others. While the search for mechanistic links between species traits and ex...

The populations of many North American forest-breeding songbirds have declined over the past few decades, initiating much research regarding the factors influencing avian use of remaining forests, many of which are highly disturbed and impacted by invasive plants. Our objective was to compare the spe-cies richness of breeding birds in riparian fore...

Background/Question/Methods We are a graduate class in Conservation Ecology at Delaware State University (DSU). On the campus is a 30-hectare forest fragment that supports a heron rookery, a pair of Bald Eagles, and a well-maintained and popular educational nature trail. This forest is also used extensively as a classroom. The Delaware Department...
Conference Paper
Background/Question/Methods Declines of neotropical migrant songbirds are well documented across the United States. In the East, 45% of forest breeding neotropical migrants showed significant declines from 1978-1987; many of which continue. Consequently, the conservation value of remaining riparian forests for breeding birds needs investigation...

In southern Mexico, four native and one introduced species of Opiinae (Braconidae) attack larvae of Anastrepha spp. fruit flies. There is a substantial overlap in the hosts of the parasitoids, and every species has been collected from fruit flies attacked by at least one or two other species. The ovipositors of these braconids have a broad interspe...

We examined the abundance and diversity of dung beetles in forest fragments within a savanna landscape near Alter do Chão, Pará, Brazil. These fragments have existed for 150 years and possibly millennia. Using pit-fall traps to capture dung beetles, we investigated fragment area, fragment isolation, and tree density in fragments as predictors of sp...

Eighty-one species of butterfl ies and two-hundred and thirty-seven spe-cies of moths were identifi ed from Fort Indiantown Gap, a National Guard training facility in south-central Pennsylvania. The Lepidoptera found here include the last remaining population of Speyeria idalia idalia (eastern regal fritillary), as well as the rare Callophrys irus...
Article
Although insects are crucial for maintaining ecosystem function, our understanding of their overall response to human activity remains limited. This is no less true of dung-burying beetles (Coleoptera: Scarabaeidae: Scarabaeinae), which provide a suite of critical ecosystem functions and services, yet but face multiple conservation threats, particu...

Mammal populations are increasingly hunted, yet the consequences of their disappearance from tropical forests have only recently been explored. Here, we summarize current research on the role of mammals in seed dispersal and postdispersal processes, such as seed predation and secondary dispersal, in different tropical regions. We evaluate how mamma...

Conservation efforts are often aimed at one or a few species. However, habitat sustainability relies on ecological interactions among species, such as seed dispersal. Thus, a community-scale conservation strategy may be more valuable in some settings. We describe communities of primary (primates) and secondary (dung beetles) seed dispersers from 5...
Article
Given current accelerated trends of tropical land conversion, forest fragments are being incorporated into many conservation programs. For investing in fragments to be a viable conservation strategy, forest fragments must maintain their ecological integrity over the long term. Based on fieldwork in 22 forest fragments in the crater lakes region of...

Seeds fromtropical fruiting trees ingested and defecated on the soil surface by primary dispersers (such as primates) are vulnerable to destruction from rodents, insects, and fungi. Burial by dung beetles as an incidental result of their feeding and nesting activities often provides these seeds with refugia from attack. To examine the effect of hab...

Dung beetles are important in several ecological processes, including nutrient recycling, soil aeration, the transport of other organisms, and the burial of vertebrate dispersed and defecated seeds. Dung beetle species vary widely in their abilities as seed dispersers. The biomass of beetle species that bury no seeds, bury small seeds only, or bury...

Iridescence, in both the visible and ultraviolet (UV) spectra, is produced by various means and may serve several functions in different animals. In insects, such colors are often considered as anti-predator adaptations, either crypsis or absenteeism, or a means of thermoregulation. A less explored alternative is social signaling. Iridescent colors...

Abstract. -Whirligig beetles (Coleoptera: Family Gyrinidae) aggregate on the surface of ponds, lakes, and streams. This study examines how these aggregations protect the beetles from pre dation. The more beetles in an aggregation, the more quickly the group as a whole responds to the approach of stimuli. Experiments indicate that individual beetles...
