The effects of clam fishing on the properties of surface sediments in the lagoon of Venice, Italy
Autor: R. J. Aspen, S. Vardy, R. G. Perkins, I. R. Davidson, R. Bates, D. M. Paterson
Publikováno v: Hydrology and Earth System Sciences, Vol 8, Iss 2, Pp 160-169 (2004)
Harvesting of clams(Tapes philippinarum) has important socio-economic and environmental implications for the Venice lagoon area, Italy. Clam harvesting disrupts the structure of benthic communities but the effects upon sediment stability and surface

Aerial Survey as a Tool to Estimate Abundance and Describe Distribution of a Carcharhinid Species, the Lemon Shark, Negaprion brevirostris
Autor: S. T. Kessel, S. H. Gruber, K. S. Gledhill, M. E. Bond, R. G. Perkins
Publikováno v: Journal of Marine Biology, Vol 2013 (2013)
Aerial survey provides an important tool to assess the abundance of both terrestrial and marine vertebrates. To date, limited work has tested the effectiveness of this technique to estimate the abundance of smaller shark species. In Bimini, Bahamas,

The Effects of Surface Mixers on Stratification, Dissolved Oxygen, and Cyanobacteria in a Shallow Eutrophic Reservoir
Autor: E. I. Slavin, D. J. Wain, L. D. Bryant, M. Amani, R. G. Perkins, C. Blenkinsopp, S. Simoncelli, S. Hurley
Publikováno v: Blenkinsopp, C, Bryant, L, Amani Geshnigani, M, Simoncelli, S, Wain, D, Slavin, E, Hurley, S & Perkins, R 2022, ' The Effects of Surface Mixers on Stratification, Dissolved Oxygen, and Cyanobacteria in a Shallow Eutrophic Reservoir ', Water Resources Research, vol. 58, no. 7, e2021WR030068 . https://doi.org/10.1029/2021WR030068
Top-down surface mixers are increasingly used in drinking water reservoirs to prevent the development of stratification, control cyanobacteria, and limit sediment release of soluble manganese. A targeted field investigation enabled the discrimination

Three decades of longlining in Bimini, Bahamas, reveals long-term trends in lemon shark Negaprion brevirostris (Carcharhinidae) catch per unit effort
Autor: S T, Kessel, A C, Hansell, S H, Gruber, T L, Guttridge, N E, Hussey, R G, Perkins
Publikováno v: Journal of fish biology. 88(6)
In Bimini, Bahamas, the consistent employment of longlines, beginning in 1982, provided a rare opportunity to explore population trends for large resident sharks. This study assessed three shallow water longline survey periods at this location; 1982-

Microspatial variability in community structure and photophysiology of calcified macroalgal microbiomes revealed by coupling of hyperspectral and high-resolution fluorescence imaging
Autor: R G, Perkins, C J, Williamson, J, Brodie, L, Barillé, P, Launeau, J, Lavaud, M L, Yallop, B, Jesus
Publikováno v: Scientific Reports
Calcifying coralline macroalgae provide biogenic habitats colonised by epiphytic microalgae that contribute significantly to community productivity. Georeferenced hyperspectral and high-resolution fluorescence imaging were coupled to microspatially m

An Urban Forestry Strategy For Ontario
Autor: J. R. Pickering, W. A. G. Morsink, R. M. U. Ubbens, R. G. Perkins, P. A. Lewis-Watts
Publikováno v: The Forestry Chronicle. 65:97-101
An urban forestry strategy is presented for Ontario, in response to a growing need to manage for viable and healthy urban vegetation. Urban forestry is about planning and managing existing and/or new treed vegetation of all types and associated wildl
