The first comprehensive revision of all the species attributed to Melomys led J. I. Menzies in 1996 to resurrect the genus Paramelomys and to redefine its morphologicallimits and species content. Menzies created P. gressitti as a new species belonging to a group displaying morphological similarities and including also P. lorentzii and P. moncktoni. Monotypic Distribution. E New Guinea. Descriptive notes. Head-body 135-162 mm, hindfoot 30-34 mm; no specific data are available for body weight. Gressitt's Mosaic-tailed Rat is a medium-sized Paramelomys with a soft, thick and woolly pelage, a long narrow foot, and a tail with three hairs per scale. It exhibits a medium-sepia dorsal pelage and a gray-buff ventral one. Tail is slightly shorter (99%) than head-body length. The skull has a narrow zygomatic plate. Habitat. Moist tropical mountain forest between 2300 m and 2400 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Gressitt's Mosaic-tailed Rat is terrestrial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Endangered on The IUCN Red List owing to its small geographic range (less than 3500 km?*) and the destruction ofits habitat by mining and logging activities. The major threat to Gressitt's Mosaic-tailed Rat is ongoing habitat degradation caused by nearby human populations; habitat on Mount Kandy has been destroyed by gold-miners and wood-cutters.

Expansion of non-native plant Flaveria bidentis (L.) Kuntze driven by range of factors leading to patchy distribution patterns
<p><span>Given the growing concern over the ecological impacts of non-native species, exploring these species' expansion edge and distribution patterns and their driving factors is important for developing suitable management measures. <em>Flaveria bidentis</em> (L.) Kuntze, a non-native plant that was introduced to China in the 1990s, has spread from southern Hebei Province, where it first took root, to the surrounding regions and has become one of the most notorious invasive weeds in northern China. Based on 15 years (2006-2021) of extensive field investigations, the spatial distribution of sampling and occurrence points were mapped in the recently expanded region of <em>F. bidentis</em>' population. Then, nearest neighbor analysis used to characterize the spatial pattern differences between samplings and occurrences. An exponential decay function was used to elucidate the driving factors contributing to the presence and absence of <em>F. bidentis</em>. Our results demonstrated an effective random sampling setup, a heterogeneous spatial distribution of <em>F. bidentis</em>, and a multi-regional independent aggregation distribution pattern (<em>p</em><0.01). There were significant spatial correlations between the aggregation areas of plant occurrence points and the locations of roads and construction sand distribution centers. These findings suggest that human activities involving major roads and construction sand distribution centers were driving factors contributing to this long-distance dispersal and spatially discontinuous distribution patterns.</span><span class="MsoCommentReference"><span> </span></span><span class="MsoCommentReference"><span>The presence of these patchy distribution patterns has important implications for ongoing efforts to manage populations of non-native species.</span></span></p>

Particle Size Distribution in the 3-100 micron size range derived from an Imaging FlowCytoboy for 4 transect cruises across the Pacific Ocean
<p>Surface, Underway Imaging FlowCytobot (IFCB) differential_particle_size_distribution (PSDn, images per L per micron for each size bin) or differential_particle_volume_concentration (VDn, microliters per L per micron for each size bin) for 50 log-spaced size bins in the ~3-100 micrometer size range. Size distribution data collected from surface waters using the ship"s flowthrough system (~ 7m) during SCOPE cruises Gradients 2, 3, 4, and 5 (http://scope.soest.hawaii.edu/data/gradients/gradients.html). The IFCB triggers on both scattering and fluorescence so both living and non-living particles are included in the binned estimates. Note that the particle abundances and/or concentrations in the first few and last size bins may be underestimated. Please use care when comparing results across cruises, since different settings per cruise may result in different sensitivity and detection levels. Particle size of individual particles was calculated from estimated biovolume using the distance-map algorithm of Moberg and Sosik (2012). Particles are assumed spherical and are binned over 50 logarithmically-spaced size classes centered between 3.11 micrometers and 98.15 micrometers. See metadata in each excel spreadsheet for information on binwidth of each size class as well as other relevant information. This dataset was not converted to Carbon units. Timestamp is in UTC.</p>
