Amphibian and Reptile Conservancy
-
ARC saves herps through a strategic, scientific, and passionate approach that allows us to make a real difference. We implement localized, regional, species-based PARCAs (Priority Amphibian and Reptile Conservation Areas) and weave them together across the country into a national strategy capable of making great impact. We practice Transformative Science with the urgency required to save those species and ecosystems at greatest risk.

10,000th Hellbender Released to the Wild
-
The Saint Louis Zoo, Missouri Department of Conservation (MDC) and U.S. Fish and Wildlife Service (FWS) are celebrating a historic milestone in hellbender conservation in Missouri. As of August 2022, the total Saint Louis Zoo-raised endangered Ozark and eastern hellbenders released into the wild since 2008 now numbers over 10,000 individuals.

The Mid-Atlantic Center for Herpetology and Conservation
-
MACHAC is a nonprofit organization dedicated to the conservation and study of amphibians and reptiles through advocacy, education, and execution of research by professional herpetologists and ecologists in the Mid-Atlantic and Northeastern United States. Major partners and funding sources for programs include the Pennsylvania Fish & Boat Commission, Pennsylvania Department of Conservation and Natural Resources, Natural Resources Conservation Service (US Department of Agriculture), United States Fish & Wildlife Service, and National Fish and Wildlife Foundation. Major MACHAC projects also include the study and recovery of state and federally-listed amphibians and reptiles, notably important initiatives centered on the Bog Turtle and Eastern Massasauga.

Effect of habitat area and isolation on fragmented animal populations
-
Habitat destruction has driven many once-contiguous animal populations into remnant patches of varying size and isolation. The underlying framework for the conservation of fragmented popu- lations is founded on the principles of island biogeography, wherein the probability of species occurrence in habitat patches varies as a function of patch size and isolation. Despite decades of research, the general importance of patch area and isolation as predictors of species occupancy in fragmented terrestrial systems remains unknown because of a lack of quantitative synthesis. Here, we compile occupancy data from 1,015 bird, mammal, reptile, amphibian, and invertebrate population networks on 6 continents and show that patch area and isolation are surprisingly poor predictors of occupancy for most species. We examine factors such as improper scaling and biases in species representation as expla- nations and find that the type of land cover separating patches most strongly affects the sensitivity of species to patch area and isolation. Our results indicate that patch area and isolation are indeed important factors affecting the occupancy of many species, but properties of the intervening matrix should not be ignored. Improving matrix quality may lead to higher conservation returns than manipulating the size and configuration of remnant patches for many of the species that persist in the aftermath of habitat destruction.
