Tracking reticulated flatwoods salamander (Ambystoma bishopi) recovery in response to habitat restoration and assisted translocations Naive (a) and predicted (b) number of occupied sites between 2003 and 2024. Naive occupancy data derived from larval captures, while predicted occupancy estimates are from a dynamic, spatially explic....

Recent publication from our lab group provides a "recipe" for wetland restoration in fire-suppressed longleaf pine flatwoods, resulting in more than doubling the number of ponds with breeding populations of reticulated flatwoods salamanders. 🌏🧪 conbio.onlinelibrary.wiley.com/doi/10.1111/...

Bees are collapsing in the U.S. A key to their secrets might vanish. The top federal lab on native bees is set to close under President Trump’s budget.

It's not going to "vanish," it's going to be eliminated by the current administration.

Digital illustration of a bright green and yellow little songbird with a ring of white feathers around the eye (nosa' luta, Rota White-eye) perched on a flowering stalk of a canopy tree (trongkon guåfi, håyun lågu, Guam fire tree). The flowers are in a cluster of three, formed of a little green bud with a small white tubular-shaped flower pointed upright, from which emerges a dazzling burst of hot pink feathery stamens. The bird has a caterpillar in its mouth, showing a potential for helping the trees defend from their herbivores. Both the bird and the tree are critically endangered.

My latest for @instbirdpop.bsky.social ! This was our 2024 winter card illustration - a break from the snow, since the end of the year comes to the tropics too! Featuring a nosa' luta (Zosterops rotensis) chowing down on a caterpillar plucked off a trongkon guåfi (Serianthes nelsonii) 🎨🪶🐡🌏 #birdart

Wetland Hydrology, Not Altered Phenology, Challenges Reticulated Flatwoods Salamander (Ambystoma bishopi) Management Under Future Climate Change Shifts in phenology have been one of the most frequently documented effects of climate change across a wide variety of taxonomic groups. These shifts can alter both species and ecosystem level process...

It took more than a decade of field work by a large and dedicated crew, and several years of data wrangling by postdocs, graduate students, and research associates, and great support from sponsors and colleagues, but exciting to see it come together! 🧪 🌎 doi.org/10.1643/h202...

Ten Principles From Evolutionary Ecology for the Effective Conservation of Reptiles and Amphibians ABSTRACT. Reptiles and amphibians are disproportionately threatened among vertebrates but are lagging behind other vertebrate taxa with regards to conservation plans. As the need to triage data-limite...

Hoping these principles can help guide conservation of amphibians and reptiles even without much baseline data, by applying theory. 🌍 🧪 meridian.allenpress.com/journal-of-h...

Thank you!

Looks beautiful! I am in the US and looking for a copy of your earlier book but I see it only as an e-book. Are your books available in print in the US? Thank you!

Aquatic Conservation: Marine and Freshwater Ecosystems: Vol 34, No 7 Aquatic Conservation: Marine and Freshwater Ecosystems is an international journal focusing on the conservation of freshwater, brackish or marine habitat.

Several former students collaborated on this paper modeling turtle habitat and one got the cover photo! Another example of how understanding topographic controls on hydrology can inform conservation of reptiles and amphibians. onlinelibrary.wiley.com/doi/full/10.... 🌏🧪

Informing the Conservation of Ephemerally Flooded Wetlands Using Hydrologic Regime and LiDAR-Based Habitat Assessments - Wetlands Integrated assessments of wetland hydrologic regimes and other environmental factors are key to understanding the ecology of species breeding in ephemerally flooded wetlands, and reproductive success ...

Modern technology can provide so much information that is useful to conservation of amphibians that breed in ephemeral wetlands. Proud of our recent paper including LiDAR data and automated water level loggers as another contribution in this area. link.springer.com/article/10.1...
