This dataset was created to serves as one sub-layer of the Florida Marine Blueprint. The Florida Marine Blueprint was created to aid in prioritizing ecosystems and habitats derived from species biodiversity, highly valued habitat and potential marine migratory corridors. Highest priority areas are those where there is high species biodiversity/richness and overlaps in valued habitats. The Blueprint will then be used to inform where potential management and conservation practices should be focused and potentially carried out.

Conclusions: Frogs and toad species were more abundant and diverse where habitat patch diversity was high or where there were forested wetland edges. Relative abundances of amphibian populations correlated positively with metrics such as the length of edge between forest and wetland, and negatively with the presence of agricultural and urban land. Thresholds/Learnings: Synopsis: This study examined landscape-level relationships for frogs and toads by measuring associations between relative abundance and species richness based on survey data derived from anuran calls and features of land cover maps for Iowa and Wisconsin. Relative abundances correlated positively with metrics such as the length of edge between forest...

Nitrogen (N) and phosphorus (P) availability limit plant growth in most terrestrial ecosystems. This review examines how variation in the relative availability of N and P, as reflected by N : P ratios of plant biomass, influences vegetation composition and functioning. Plastic responses of plants to N and P supply cause up to 50-fold variation in biomass N : P ratios, associated with differences in root allocation, nutrient uptake, biomass turnover and reproductive output. Optimal N : P ratios ? those of plants whose growth is equally limited by N and P ? depend on species, growth rate, plant age and plant parts. At vegetation level, N : P ratios <10 and >20 often (not always) correspond to N- and P-limited biomass...
There has been uncertainty in the national gap analysis program about including non-breeding birds in distribution models because of concerns that distributions of migrant and winter birds are difficult to predict and are not necessary to assess biodiversity patterns. New Mexico gap analysis included migrant and non-breeding birds assuming that distributions could be predicted using habitat associations, and that excluding non-breeding bird habitat from avian richness projections potentially underestimates community types important to birds. We compared biodiversity estimates including non-breeding birds (inclusive estimate - 324 species) to estimates including only breeding birds (breeding bird estimate - 257 species)...

Summary (from http://onlinelibrary.wiley.com/doi/10.1111/fwb.12807/abstract) Conservation of freshwater unionid mussels presents unique challenges due to their distinctive life cycle, cryptic occurrence and imperilled status. Relevant ecological information is urgently needed to guide their management and conservation. We adopted a modelling approach, which is a novel application to freshwater mussels to enhance inference on rare species, by borrowing data among species in a hierarchical framework to conduct the most comprehensive occurrence analysis for freshwater mussels to date. We incorporated imperfect detection to more accurately examine effects of biotic and abiotic factors at multiple scales on the occurrence...

This data package contains three tables: 1) avian point-transect survey data collected on the Seward Peninsula in 2012, 2) locations of all survey sites, and 3) an avian taxonomy table for reference. Version History: First release: January 2015 Revised: February 2023 (ver. 2.0)
Species richness of large pelagic fish - The richness of target species values were calculated to outline the diversity of the species in each ten minute square. The essential fish habitat (EFH) metrics were developed to understand how much of the region is considered EFH and to identify points were EFH for the target species overlapped. The persistence score identifies which target species were observed in the same ten minute square over time. The days fished metrics were calculated to understand the distribution of gillnet, longline, and bottom longline fishing trips.

This data layer represents the Species Richness Priorities within PFLCC's Connectivity Priority Resource. The analysis was performed with the Connectivity Priority Resource data layer and the Species Richness layer in CLIP 4.0, which originally was part of FNAI's work for the Florida Forever program. For meta data for PFLCC's Connectivity Priority Resource plase see the data set of the same name. FWC Potential Habitat Richness - FWC also developed the potential habitat richness layer to identify areas of overlapping vertebrate species habitat. FWC created a statewide potential habitat model for each species included in their analysis. The Potential Habitat Richness layer includes the entire potential habitat model...

Shrub encroachment due to overgrazing has led to dramatic changes of savanna landscapes and is considered to be one of the most threatening forms of rangeland degradation e.g. via habitat fragmentation. Mammalian carnivores are particularly vulnerable to local extinction in fragmented landscapes. However, our understanding of how shrub encroachment affects mammalian carnivores is poor. Here we investigated the relative sensitivities of ten native carnivores to different levels of shrub cover ranging from low (<5%) to high shrub cover (>25%) in 20 southern Kalahari rangeland sites. Relative abundance of carnivores was monitored along 40 sand transects (5 m × 250 m) for each site. Our results show that increasing...
We attempted a complete review of the empirical literature on effects of roads and traffic on animal abundance and distribution. We found 79 studies, with results for 131 species and 30 species groups. Overall, the number of documented negative effects of roads on animal abundance outnumbered the number of positive effects by a factor of 5; 114 responses were negative, 22 were positive, and 56 showed no effect. Amphibians and reptiles tended to show negative effects. Birds showed mainly negative or no effects, with a few positive effects for some small birds and for vultures. Small mammals generally showed either positive effects or no effect, mid-sized mammals showed either negative effects or no effect, and large...

Conclusions:Over time, native species richness increased slightly, but dropped dramatically after several years of burning. Year-to-year change in community composition was found to be affected by time since fire and fluctuations in growing season temperature and rainfall. Examining successional trajectory showed that the restoration has been most successful at reducing exotic species and increasing species heterogeneity, but has largely failed to increase native species richness at the level of remnant prairies, largely due to interspecies resource competition.Thresholds/Learnings:
Arthropods living in the canopies of two woody shrub species (a sub-shrub (Gutierrezia sarothrae) and a large shrub (Prosopis glandulosa)) and perennial grasses plus associated herbaceous species, were sampled on 18, 0.5 hectare plots in a Chihuahuan Desert grassland for five consecutive years. Mesquite shrubs were removed from nine plots, six plots were grazed by yearling cattle in August and six plots were grazed in February for the last 3 years of the 5 year study. Arthropod species richness ranged between 154 and 353 on grasses, from 120 to 266 on G. sarothrae, and from 69 to 116 on P. glandulosa. There was a significant relationship between the number of families of insects on grass and G. sarothrae and growing...
Increasing demands on arid and semiarid ecosystems, which comprise one-third of Earth's terrestrial environment, create an urgent need to understand their biodiversity, function, and mechanisms of change. Sagebrush (Artemisia) steppe, the largest semiarid vegetation type in North America, is endangered because of losses to agriculture, excessive grazing, and invasive species. Establishment in 1950 of what is now designated as the Idaho National Engineering and Environmental Laboratory (southeastern Idaho, USA) created the largest existing reserve of this extensive vegetation type. We used cover, density, and frequency data for vascular plants sampled on 79 permanent plots nine times during 45 years to (1) assess...
