Burrowing marine infauna are morphologically diverse and range in size over several orders of magnitude. Whilst effects of ontogenetic and morphological differences on running, flying and swimming are relatively well understood, similar analyses of burrowing mechanics and kinematics are lacking. The polychaete Nereis virens Sars extends its burrow by fracture, using an eversible pharynx to exer...

Cheek-marking in yellow-bellied marmots (Marmota flaviventris) was studied by observations of cheek-marking in two colonies from 10 June to 6 August, 1996 and by experimental studies of responses to olfactory secretions from the perioral gland. The rate of cheek-marking declined significantly as the season progressed. Most cheek-marking occurred within 3 m of the main burrow system and was prim...

In one-dimensional (1D) early diagenetic models, bioirrigation is typically represented by a nonlocal mass transfer or bioirrigation coefficient, . Usually, all pore water species are assigned the same . Here, we show that this assumption can lead to significant errors in estimates of bioirrigation intensities. Using a simplified early diagenetic reaction network, we compute the 3D concentratio...

Burrows are common animal habitations, yet living in a burrow presents physiological challenges for its inhabitants because the burrow isolates them from sources and sinks for oxygen, carbon dioxide, water vapor and ammonia. Conventionally, the isolation is thought to be overcome by either diffusion gas exchange within the burrow or some means of capturing wind energy to power steady or quasi-s...

Bioturbation of infauna plays an important role in the biogeochemical processing sediments. Infaunal animals build burrows and enlarge sediment-water interface by their activities so bioturbation is closely related with burrow structure animal behavior sediment. The purpose this study to explore characteristics Perinereis aibuhitensis structures factors months sizes (0-1g, 1-2g, 2-3g, 3-4g, &am...

The trace fossil Lepidenteron lewesiensis (Mantell 1822) provides an exceptional taphonomic window to diversity of fishes as shown for the Upper Cretaceous of Poland, in the Middle Turonian-Lower Maastrichtian deposits of the Opole Trough, Miechów Trough, Mazury-Podlasie Homocline, and SE part of the Border Synclinorium. Lepidenteron lewesiensis is an unbranched burrow lined with small fish sca...

The 2-page document intends to provide readers with quick information (mode of action, weeds controlled, postharvest interval, usage restrictions, suggested rates, etc.) on different preemergent or soil-residual herbicides used in citrus.

BACKGROUND The Natural History Museum (NHM) sound archive contains recordings of Gryllotalpidae, and the NHM collection holds plaster casts of the burrows of two species. These recordings and burrows have until now not been made available through the NHM's collection database, making it hard for researchers to make use of these resources. NEW INFORMATION Eighteen recordings of mole crickets (...

Laboratory and field studies were conducted between July and October 1999 to identify bait preference, biomarker efficacy, and bait acceptance rates for delivering an oral plague vaccine to black-tailed prairie dogs (Cynomys ludovicianus). Twenty juvenile captive prairie dogs were offered alfalfa baits containing either alfalfa, alfalfa and 5% molasses, or alfalfa, 5% molasses and 4% salt. Base...
