Annotation:

Monsoon rainforests form an archipelago of small habitat fragments throughout the wet-dry tropics of northern Australia. According to the definition of Winter (1988) the current monsoon rainforest mammal assemblage contains only one rainforest specialist mammal species (restricted to Cape York Peninsula), and is dominated by eutherian habitat generalists (murids and bats) that mostly occur in surrounding savannah habitats. The mammal assemblages in monsoon rainforests across northern Australia (Cape York Peninsula, Northern Territory and the Kimberley) are essentially regional subsets of the l

Background One of the biggest challenges in conservation is to manage multiple habitats for the effective conservation of multiple species, especially when the focal species are mobile and use multiple resources across heterogeneous protected areas. The application of ecological network tools and the analysis of the resulting species–habitat networks can help to describe such complex spatial associations and improve the conservation of species at the landscape scale. Methods To exemplify the application of species–habitat networks, we present a case study on butterflies inhabiting multiple gra

Species’ traits influence how populations respond to land-use change. However, even in well-characterized groups such as birds, widely studied traits explain only a modest proportion of the variance in response across species. Here, we show that associations with particular forest types strongly predict the sensitivity of forest-dwelling Amazonian birds to agriculture. Incorporating these fine-scale habitat associations into models of population response dramatically improves predictive performance and markedly outperforms the functional traits that commonly appear in similar analyses.

In seasonal environments, sinks that are more persistent than sources may serve as temporal stepping stones for specialists. However, this possibility has to our knowledge, not been demonstrated to date, as such environments are thought to select for generalists, and the role of sinks, both in the field and in the laboratory, is difficult to document. Here, we used laboratory experiments to show that herbivorous arthropods associated with seasonally absent main (source) habitats can endure on a suboptimal (sink) host for several generations, albeit with a negative growth rate.

Population performance along habitat gradients is predicted to differ among species that differ in their degree of habitat specialization. We compared a specialized rodent (the eastern chipmunk, Tamias striatus) with a generalist (the white-footed mouse, Peromyscus leucopus) that occurs across a wider range of habitats. Populations were seasonally livetrapped on 10 small forested sites every 2 weeks for 4 years. Linear regressions were used to relate density, residency, and reproduction to microhabitat gradients developed by hierarchical factor analysis of vegetation variables. Densities of bo

The ecological effects of habitat use by herpetofaunal species vary widely and recognizing relative habitat value will help to improve conservation theory and practice in a particular landscape.

Spatial distributions of many tropical trees are skewed to specific habitats, i.e. habitat specialization. However, habitats of specialist species must be divergent, i.e. habitat divergence, to coexist in a local community. When a pair of species specialize in the same habitat, i.e. habitat convergence, they could not coexist by way of habitat specialization. Thus, analyses of habitat divergence, in addition to habitat specialization, are necessary to discuss coexistence mechanisms of sympatric species. In this study, the habitat specialization and habitat divergence along topographic gradient

ABSTRACT Birds that inhabit white-sand ecosystems (WSE) in the Amazon are adapted to habitats distributed as isolated patches. These environments occur in sandy soils that are extremely poor in nutrients, have low floristic diversity and support bird assemblages restricted to WSE. We investigated whether bird species specialized in WSE have morphological or ecological traits that distinguish them from generalist birds that share the same habitat but are not restricted to WSE. We collected morphological and ecological data from 22 specialist and 102 generalist bird species from WSE and describe

Understanding how animals use their habitat is an important part of ecology because it links an individual’s life history with movement and resource exploitation. Animals have to move in some form or another to satisfy their energetic and reproductive needs, which is essential for fitness and survival. The patchy distribution of resources (i.e. food, shelter, mates) within heterogenous landscapes has a strong influence on animal movement. By analysing movement patterns of individuals, we can get a better understanding of the factors influencing the spatio-temporal use of patches. Habitat fragm

First, I examined variation of body and extremity size across its geographical distribution, and found size was curvilinearly related to latitude, consistent with the abundant centre hypothes

Abstract The Purple Heron is a bird adapted to and dependent on a very specific habitat—dense reed beds. Its long toes, short tarsus, thin body and head, and long bill can be seen as adaptations for living in this habitat (Boev 1988a). It feeds by solitarily waiting patiently for prey or by Walking slowly over and through the reeds. It is also a diet specialist and is among the most morphologically specialized of European herons for fish eating (Boev 1989). Together, these characteristics indicate that it has among the narrowest of ecological niches of the typical herons.

Biotope or habitat preferences are important species characteristics that can be used for understanding their ecology, as well as their conservation, and even as a tool for crime investigations for detection of post-mortem body manipulation. However, the characterization of species� habitat preferences can be difficult. There are several limiting factors like lack of quantitative data and reliance on anecdotal evidence for this trait. Further, we must consider the reaction to the border between two neighboring habitats. These ecotones are important biodiversity hotspots in the landscape, which

Identifying geographic areas with habitats suitable for the presence of priority species is of essential importance in conservation planning. A useful tool to identify these areas is a species distribution modelling (SDM), which is a method that defines statistical relationship between species records and environmental variables in the localities where the species is present. To test the possibility of applying this method in conservation planning, this study focused on the Three-toed Woodpecker Picoides tridactylus (Linnaeus, 1758) (Piciformes: Picidae) because it is a glacial relict on the B

The first two fundamental principles in the ASME Code of Ethics are that” engineers uphold and advance the integrity, honor and dignity of the engineering profession by: I. Using their knowledge and skill for the advancement of human welfare; II. Being honest and impartial, and serving with fidelity the public, their employers and clients…” These principles involve the concept of “the public good” and are properly part of engineering ethics — yet it is difficult to find a good place in the curriculum to address these principles.

Wetlands play a crucial role in watersheds and provide critical ecosystem functions, most notably, water quality improvement, fish and wildlife habitat, flood attenuation, drought mitigation, and carbon sequestration. Wetlands in Utah are regulated primarily by the federal government under the Clean Water Act (CWA), which requires mitigation to replace ecological services that are lost to permitted activities. Utah House Bill 118 (2022) directed the Utah Geological Survey to explore the potential for an In-Lieu Fee (ILF) mitigation program to improve wetland resources in Utah. An ILF program w
