Última Changes in Mammalian Body Length over 175 Years—Adaptations to a Fragmented Landscape? Ecology and Society Schmidt, Niels Martin; Royal Veterinary and Agricultural University; nms@kvl.dk; Jensen, Per Moestrup; Royal Veterinary and Agricultural University; pmj@kvl.dk. The potential consequences of anthropogenic habitat fragmentation on species diversity and extinction have drawn considerable attention in recent decades. In many cases, traditional island biogeography theory has been applied to explain the observed patterns. Here, we propose that habitat fragmentation as a selective force can be traced in mammalian body length changes. By exploring historical sources, we are able to show that the body length of Danish mammals has altered over a period of 175 years, possibly in response to increasing habitat fragmentation. The rate of body length change was generally lowest in medium-sized mammals, and increased with both smaller and larger body mass. Small mammals have generally increased, whereas large mammals have...

Ano: 2003 Concomitant Patterns in Avian and Mammalian Body Length Changes in Denmark Ecology and Society Schmidt, Niels Martin; Royal Veterinary and Agricultural University; nms@kvl.dk; Jensen, Per Moestrup; Royal Veterinary and Agricultural University; pmj@kvl.dk. We gathered length data on 61 Danish breeding birds from the past 200 years, and related the pattern of change to present body mass and other ecological parameters. Body mass was the only parameter significantly correlated with the rate of change, and the emerging pattern in the rate of change followed the island rule. That is, smaller species have become larger and vice versa, while the medium-sized species remain essentially unchanged. The suggested optimal body mass was around 85 g. Though orders of magnitude lower, the pattern in avian body size change was similar to that of Danish mammals. Our analyses suggest that increasing habitat fragmentation leads to altered body size towards being medium-sized in Danish vertebrates. The changing landscape,...

Ano: 2005 Patch Size and Population Density: the Effect of Immigration Behavior Ecology and Society Bowman, Jeff; Ontario Ministry of Natural Resources; jeff.bowman@mnr.gov.on.ca; Cappuccino, Naomi; Carleton University; ncappucc@ccs.carleton.ca; Fahrig, Lenore; Carleton University; lfahrig@ccs.carleton.ca. Many habitat fragmentation experiments make the prediction that animal population density will be positively related to fragment, or patch, size. The mechanism that is supposed to result in this prediction is unclear, but several recent reviews have demonstrated that population density often is negatively related to patch size. Immigration behavior is likely to have an important effect on population density for species that do not show strong edge effects, for species that have low emigration rates, and during short-term habitat fragmentation experiments. We consider the effect that different kinds of immigration behaviors will have on population density and we demonstrate that only a minority of possible scenarios produce positive density vs. patch size...

Ano: 2002 sars: an R package for fitting, evaluating and comparing species–area relationship models ArchiMer Matthews, Thomas J.; Triantis, Kostas; Whittaker, Robert J.; Guilhaumon, François. The species–area relationship (SAR) constitutes one of the most general ecological patterns globally. A number of different SAR models have been proposed. Recent work has shown that no single model universally provides the best fit to empirical SAR datasets: multiple models may be of practical and theoretical interest. However, there are no software packages available that a) allow users to fit the full range of published SAR models, or b) provide functions to undertake a range of additional SAR‐related analyses. To address these needs, we have developed the R package ‘sars’ that provides a wide variety of SAR‐related functionality. The package provides functions to: a) fit 20 SAR models using non‐linear and linear regression, b) calculate multi‐model...

Leaf morphology was measured and aerodynamical attributes as well as transpiration rates were calculated for the mangrove Conocarpus erecta from sites naturally sheltered or sites exposed to oceanic winds at Socorro Island, Mexico, and compared with those of C. erecta, Laguncularia racemosa, and Rhizophora mangle at a mainland estuary near La Manzanilla, Jalisco, Mexico. Leaves of C. erecta, 5.98 cm in length and 2.03 cm in width, were the smallest and most streamlined of the mainland mangroves. Moreover, both leaf dimensions were 32 % smaller for trees from the exposed sites on Socorro Island than on the mainland. For a given wind velocity, Reynolds numbers were 10 to 33 % lower at Socorro Island than on the mainland for leaves of C. erecta, leading to a...

Given its complex zoogeography and large number of islands insular Southeast Asia makes an excellent subject for studying the interrelationships of species richness, island area and isolation. The islands are merely highpoints of an immense shallow continental shelf which during Pleistocene glacial periods was exposed periodically as dry land connecting the now isolated islands with one another. The area is home to a large number of primate taxa, including many endemic to the region (Nasalis, Presbytis, Pongo, Symphalangus, Simias, Tarsius). Worldwide, the number of described (extant) species of primates has doubled in the last two decades partially as a result of applying a different species concept (viz. Phylogenetic Species Concept PSC as opposed to the... Tipo: Article / Letter to the editor Palavras-chave: Endemism; Extinction; Island biogeography; Phylogeny; Species concepts; Sunda Shelf; 42.84.
