Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider

Integrative Zoology, EarlyView.
We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

Cladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

Using eDNA to detect the distribution and density of invasive crayfish in the Honghe-Hani rice terrace World Heritage site.

PLoS ONE, 2017
The Honghe-Hani landscape in China is a UNESCO World Natural Heritage site due to the beauty of its thousands of rice terraces, but these structures are in danger from the invasive crayfish Procambarus clarkii.

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Lake Hańcza – a new site for signal crayfish (Pacifastacus leniusculus Dana) occurrence in Poland

Archives of Polish Fisheries, 2018
Crayfish catches were conducted using traps in Lake Hańcza, which is the deepest lake in Poland. Two crayfish populations were found to co-exist in the lake: spiny-cheek crayfish (Orconectes limosus Raf.) and signal crayfish (Pacifastacus leniusculus ...

Integrated species distribution modeling to assess species status and current and future threats for an imperiled amphibian

Conservation Science and Practice, EarlyView.
To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Baseline study on the fish and freshwater crayfish fauna in the Blackwood River and its tributaries receiving discharge from the Yarragadee Aquifer [PDF]

, 2005
Water from the Yarragadee Aquifer surfaces in Poison Gully and Milyeannup Brook, and maintains flow in these Blackwood River tributaries throughout the year. It also enters Layman Brook during winter and spring, yet this stream dries during summer.
