Roadkill is a serious threat to biodiversity conservation especially when roads are near natural habitats of wildlife, such as the Emas National Park (ENP), Protected Area in Mid-west Brazil Cerrado Biome. We aimed identify species killed on stretch GO-341 highway that tangent ENP. investigated if roadkills were influenced by seasonality, sugar cane harvest and activity pattern animals (diurnal...

Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales their feeding seasons are typically restricted a limited temporal window and marine notoriously patchy. We assessed the value of six most common nearshore zooplankton species collected within Oregon, United States range Pa...

Abstract. Oxygen minimum zones (OMZs) are oceanic areas largely depleted in dissolved oxygen, nowadays considered expansion the face of global warming. To investigate relationship between OMZ and climate changes during late Quaternary, quantitative oxygen reconstructions needed but still their early development. Here, past bottom water oxygenation (BWO) was quantitatively assessed through a new...

Both sexes of P. aydini sp. nov. are described in detail. The new species can be differentiated from its congeners by the combination of following features; i) 2-segmented P5 exopod with total of five setae in the male, ii) 9-segmented antennule, iii) spinular rows near outer margin of the basis of P1-P4 significantly reduced, iv) P4 enp-3 with four setae, v) inner terminal seta of caudal rami ...

We discuss some rough set tools for perception modelling that have been developed in our project for a system for modelling networks of classifiers for compound concepts. Such networks make it possible to recognize behavioral patterns of objects and their parts changing over time. We present a method that we call a method for on-line elimination of non-relevant parts (ENP). This method was deve...

STOCK DEFINITION AND GEOGRAPHIC RANGE Once common throughout the Northern Hemisphere, the gray whale became extinct in the Atlantic by the early 1700s (Fraser 1970; Mead and Mitchell 1984), though one anomalous sighting occurred in the Mediterranean Sea in 2010 (Scheinin et al. 2011). Gray whales are now only found in the North Pacific. Genetic comparisons indicate there are distinct “Eastern N...

Two types of diodes designed for infrared applications were fabricated from SiGe/Si films grown using ultra high vacuum chemical vapor deposition. The first diode described is a PIN type design, where the I region is comprised of undoped Sil_xGex/Si multiple quantum wells. Photoluminescence and defect etching were used to assess the quality of the quantum well films, and electroluminescence and...

Geographic variations in size and proportions of blue whales (Balaenoptera musculus) were investigated using length data acquired from whaling records aerial photogrammetric surveys. Results showed that found the eastern Pacific off Central North America are significantly shorter (by approximately 2m) than at higher latitudes Pacific. support occurrence a morphologically distinct (ENP) whale po...
