Enhancement of Floral Species Richness in Glaciated Prairie Temporary Wetlands
… Pothole Region wetlands frequently recover plant species richness resembling undisturbed conditions. However, plant species richness in temporarily flooded wetlands often recovers poorly due to colonization by aggressive undesirable species. This study was conducted during 1995 and 1996 in eastern …

The effects of urbanisation on bee and wasp communities in Cape Town, South Africa
… the effects of urbanisation and availability of floral resources on bee and wasp (pollinator) diversity, community composition, and nesting guild distribution across an urbanrural/natural gradient. Using pan traps, specimens were collected from 18 sites in the austral spring of 2019 and 2020. A …

Determining vegetation metric robustness to environmental and methodological variables, and coefficients of conservatism for the flora of the Middle Rio Grande, New Mexico
… measures of vegetation structure and measures of species diversity and composition. Metrics of species diversity and composition are often used as proxies for overall biological diversity of a site, but some metrics may be misleading in their ability to fully capture the integrity of ecological …

Habitat variation effects on cavity-nesting bee fitness, community assemblages, and parasite interactions in the Colorado Front Range
… used the solitary bee, Osmia lignaria as a model species to evaluate bee fitness responses to variations in forest structure, floral density, and climatic conditions. I found that O. lignaria foraged for pollen from specific flora, regardless of on-site presence, which was affected by climate and …

Ecosystem effects of a rock-lobster 'invasion': comparitive and modelling approaches
… of rock lobsters, macroalgae and sessile species, whereas non-invaded sites had greater amounts of herbivores and encrusting corallines. Abalone abundance reflected their previouslyrecorded dependency on urchins and the effects of rampant poaching. Floral species diversity was on average …

Exploring the past and the present in order to predict the future: herbarium specimens, field data and extinction probability for conservation managers
… actions to mitigate these threats and save species from extinction. Monitoring species for a trend in population reduction is particularly difficult when protected area management is faced with a large list of species under its custodianship. Exacerbating this problem is the current format …
