Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...

Habitat fragmentation is considered to be a leading cause that is responsible for the long-term population declines of Northern Bobwhites. There are numerous factors responsible for habitat fragmentation such as expanding suburbanization, intensification of agricultural and forestry practices, and invasions of exotic plants; the unifying theme is how people use land for settlement and the production of food and fiber. As patches of habitat become smaller and more isolated, populations experience a lower probability of persistence that results in local extinctions, which can lead to larger, and perhaps even regional extinctions. However, we lack a strong empirical and quantified basis that describes the numerical...

The RESTORE Act (33 U.S. Code § 1321) directs 80% of Clean Water Act penalties from the Deepwater Horizon oil spill (likely to be in the billions) to Gulf of Mexico restoration. Gulf partners profess a common goal of “restoring and protecting the natural resources…and economy of the Gulf Coast region”(Gulf Coast Ecosystem Restoration Council 2013:2), yet specific and explicit objectives that quantify what it means to actually achieve this goal remain undefined. Despite the presence of numerous conservation partnerships along the Gulf of Mexico, there is concern that this unprecedented opportunity will lack a coordinated response (NOAA RESTORE Act Science Program 2013). The success of the RESTORE Act will hinge...

Habitat fragmentation and degradation are considered to be a leading causes of long-term population declines of Northern Bobwhites and many other species of grassland birds, such as Eastern Meadowlark. Research is needed to understand the factors causing habitat loss and fragmentation and to identify the areas that are high-probability candidates for successful restoration so that optimal decisions can be made. For example, uncertainty exists regarding the impacts of energy development activities or climate change that affect significant portions of wildlife populations in the GCP LCC. Furthermore, changing land ownership coupled with woody shrub and exotic grass encroachment have reduced the amount and quality...

Monarch butterfly and other pollinators are in trouble. Monarch butterfly habitat— including milkweed host plants and nectar food sources—has declined drastically throughout most of the United States. Observed overwinter population levels have also exhibited a long-term downward trend, suggesting a strong relationship between habitat loss and monarch population declines. Preliminary research results from a U.S. Geological Survey led effort indicate that we need a comprehensive conservation strategy that includes all land types in order to stabilize monarch populations at levels necessary to adequately minimize extinction risk—urban areas will likely play a critical role. This strategy reflects an integrated and...

The Southeast Aquatic Resources Partnership, a partner in the Gulf Coast Prairie Landscape Conservation Cooperative, is advancing instream flow science by developing basic information necessary to support flow standards and water management recommendations for waterways throughout the region. Helping resource managers prepare for future population growth and climate change-associated flow alterations at regional and local scales will enable state and federal agencies to focus regulatory and management efforts on habitats most vulnerable to altered flow. They will be able to develop more effective management strategies to minimize impacts to fish and wildlife and better inform policy-makers on conservation needs.

The southeast United States’ rivers and streams support the most diverse unionid (freshwater mussel) fauna on earth. These species are a focus of the GCP LCC because their sensitivity to habitat degradation, fish community changes, and changes in water quality and quantity make them akin to the proverbial ‘canary in the coal mine.’ They are essential components of riverine ecosystems, influencing nutrient cycling and macro-invertebrate diversity. Their decline during the past century stems from overharvest, water pollution, habitat fragmentation, and introduction of nonindigenous predators and exotic mollusks; however, habitat degradation has been the most influential.

Gulf Coast Prairie Landscape Conservation Cooperative partners need new computer models to help address threats to grassland habitats, such as land conversion and habitat fragmentation, affecting LCC focal species such as the northern bobwhite and eastern meadowlark. These tools will help partners determine the best places to invest limited resources in conserving and restoring grasslands to support self-sustaining wildlife populations.

The basic task of inventorying biodiversity has actually been under way for many years. Existing natural history museum collections, like those in which we work, can provide major contributions to such inventories in the form of valuable historic organism occurrence records, and their specimens can be used in many ways for basic research and applied conservation planning. Unfortunately, much of the wealth of information stored in natural history collections requires substantial investment to be made accessible and useful to natural resource managers and researchers. We were charged by the GPLCC with providing some of the inventory data that will be required, and to assess what other data may be available and what...

Assessing the vulnerability of species or ecosystems to climate change and formulating appropriate management responses requires predictions of the exposure and sensitivity of the species or ecosystems to projected changes. This collaborative effort by the Sonoran Joint Venture, Desert Landscape Conservation Cooperative, and Point Reyes Bird Observatory will develop a foundation for monitoring environmental change in the desert southwest by identifying where and what to monitor in order to evaluate climate-change impacts.Climate change will not have the same effects in all locations of the southwest. Some areas will change quickly (hotspots) and others will change slowly (refugia). Identifying both types of areas...

Alligator Gar, Atractosteus spatula, is an iconic species native to lowland floodplain river systems where they play an important role as top predators and by linking landscapes through their movement. Alligator Gar is also an important native fisheries species in the Trinity River. Disruption of river-floodplain connectivity is implicated in declining populations of Alligator Gar across much of its range. Successful management and conservation of Alligator Gar populations will be aided by an understanding of the relationship between flow and recruitment, particularly the availability and suitability of off-channel habitats utilized by this species for reproduction.

Habitat loss and degradation due to urban expansion and other human activities have raised concerns for the Western Gulf Coast Mottled Duck population. This species relies on tidal, palustrine, and agricultural wetlands as well as grasslands for all of its life cycle needs. The disappearance of suitable nesting and brood-rearing habitat is believed to be the primary factor associated with long-term population decline of the mottled duck. One of the first science projects initiated by the GCP LCC was development of a spatially-explicit Decision Support Tool (DST) to help guide conservation and management of habitat for breeding Mottled Ducks in coastal Louisiana and Texas. An important next step is evaluating the...
