Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

The Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Coenotic structure, skull asymmetries and other morphological anomalies in small mammals near an electronuclear power plant

Hystrix, the Italian Journal of Mammalogy, 1994
<strong>Abstract</strong> A nuclear power plant was in operation in the Garigliano alluvial plain (Central Italy) from 1964 through 1978, a period marked by several accidents. The nuclear site is now utilized for storage of radiactive wastes

Determination of heavy metal deposition in the county of Obrenovac (Serbia) using mosses as bioindicators, IV: Manganese (Mn), Molybdenum (Mo), and Nickel (Ni) [PDF]

Archives of Biological Sciences, 2009
In this study, the deposition of three heavy metals (Mn, Mo, and Ni) in the county of Obrenovac (Serbia) in four moss taxa (Bryum argenteum, Bryum capillare, Brachythecium sp., and Hypnum cupressiforme) is presented.

Between and Within Bay Differences in Mesozooplankton Assemblages in the Central and Eastern Baltic Sea: An Exploratory Study

Biological Diversity, EarlyView.
Mesozooplankton assemblages differed significantly both between and within Baltic Sea bays, driven mainly by local salinity and temperature gradients. Distinct communities occurred over distances of less than 1 km, demonstrating strong fine‐scale spatial variability.

Nitrogen Deposition Enhances Photosynthesis in Moso Bamboo but Increases Susceptibility to Other Stress Factors

Frontiers in Plant Science, 2017
Atmospheric nitrogen (N) deposition can increase the susceptibility of vascular plants to other stresses, but the physiological basis of such a response remains poorly understood.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Dwarf shrubs as bioindicators. [PDF]

Silva Fennica, 1981
Several studies of air polluted forest environments have shown that dwarf shrubs suffer from air pollution. In many cases the disturbances have been attributed to the susceptibility of the dwarf shrubs, while in some cases the vegetational competition factor has been discussed.

Searching for bioindicators of forest fragmentation: passerine birds in the Atlantic forest of southeastern Brazil Busca por bioindicadores de fragmentação florestal: aves Passeriformes na Floresta Atlântica do Sudeste do Brasil

Brazilian Journal of Biology, 2008
Aiming to evaluate the potential of Passerine birds as bioindicators of forest fragmentation, we studied the avifauna in the mountain region of the state of Rio de Janeiro by mist-netting between 2001 and 2005.
