Habitat and population structure of the Morelet’s crocodile (Crocodylus moreletii) in Calakmul Biosphere Reserve, Campeche, Mexico
… of C. moreletii within and around CBR through N-mixture modelling to estimate local abundances and population sizes, and population genetic analyses using SNPs generated through a double-digest RADseq approach (dd-RADseq).A total of 85 waterbodies were located and described throughout CBR, out of …

Distribution and Population Characterization of Clinch Dace (Chrosomus sp. cf. saylori) in the Upper Clinch River System, Virginia
… backpack electrofishing than minnow trapping. N-mixture models suggest that Clinch Dace are more abundant in watersheds with high forest cover although forest cover is highly correlated spatially in the nested stream network. Density estimates from mark-recapture sampling suggest that Clinch Dace …

Investigation and Characterization of the Optical, Thermal, and Adsorption Properties of Carbon Aerogels for CO2 Capture Applications
… breakthrough experiments with a 11% CO₂ / 89% N₂ mixture at 25 °C, followed by photothermal desorption at 110 °C, were performed to determine CO₂ capacity and regeneration performance. Optical measurements showed negligible transmittance and low reflectance from the ultraviolet through the …

Evaluating population estimates of mountain goats based on citizen science
… between volunteers and biologists. I used N-mixture models, which calculated detection probability through patterns of detection and non-detection to obtain estimates of abundance. Population estimates made by citizen science overlapped estimates by biologists and estimates from previous …

Electrochemical detection of chemical warfare agents
… (2) by removing the Boc-group with TFA/Et₃N mixture in dichloromethane. Compound 2 reacted with alkylating agents like MeI, EtI, EtSCH₂CH₂Cl (MA) and (CN)(EtO)₂P(O) (NA) to form MeNH-Fc-COOMe (3), EtNH-Fc-COOMe (4), EtSCH₂CH₂NH-Fc-COOMe (5), (EtO)₂P(O)NH-Fc-COOMe (6), respectively. Cyclic …

Population Size And Habitat Association Of Etheostoma Nebra, The Buck Darter, Using Abundance Modeling In The Buck Creek System, Cumberland River Drainage, Kentucky
… = 63.5 mm, TLfemales = 54.5 mm). Using N -Mixture models to predict abundance based on measured habitat variables and to account for imperfect detection, the total population in both streams was estimated to consist of approximately 17,000 individuals. Analyses of the two occupied streams …

Migratory Stopover of Songbirds in the Western Lake Erie Basin
… and Madsen (2011) generalized hierarchical N-mixture model. This is an open-population model that simultaneously estimates parameters that influence the abundance and detection probability of study species. Detection probabilities for transient migrants varied by survey technician, wind speed, …

The Relative Contribution of Hudson River Tributaries to River Herring Spawning Dynamics
Quantifying the relative tributary contribution to anadromous fish spawning dynamics is irrefutably important when prioritizing habitat enhancement, restoration and management decisions (Everly and Boreman, 1999). Collecting sound baseline data becomes critical when seeking out the most significant …
