Urban forests host rich polypore assemblages in a Nordic metropolitan area
<p>This dataset contains data for a manuscript titled 'Urban forests host rich polypore assemblages in a Nordic metropolitan area' where we have studied associations between the diversity of dead-wood inhabiting fungi and urbanization. The included spreadsheets contain data used in the analyses, i.e. polypore species occurrences, species richness and environmental data, accompanied by annotations about the characteristics of the study sites and individual dead-wood units. Data is given at two spatial scales on two separate spreadsheets: one at the level of dead-wood units and the other at the level of forest stands. Variable explanations are provided in separate text files.

Reproductive effort and terminal investment in a multi-species assemblage of Amazon electric fish
<p>The terminal investment hypothesis (TIH) predicts that individuals with favorable prospects for future reproduction (i.e., high residual reproductive value, RRV) should moderate current reproductive investment in favor of growth, survival, and future reproduction, whereas those with low RRV should 'terminally invest' by diverting somatic resources towards current reproduction at the expense of future reproduction. However, support for the TIH in wild animal populations is fragmentary, and the ecological contexts of terminal investment remain poorly known. We report a remarkable case of simultaneous terminal investment involving five sympatric species of the electric knifefish genus <i>Brachyhypopomus</i>, from Amazonian floodplain and terra firme stream habitats. We found that terminal investment is synchronized by seasonal breeding, in response to circannual environmental variation in mortality risk. Four species exhibit a uniseasonal iteroparous (annual) life history with complete post-reproductive mortality after a single breeding season. One species (<i>B. beebei</i>) exhibits a two-year multiseasonal iteroparous life history with breeding in two seasons and post-reproductive mortality after the second. In mature females and (most) males of the annual species, as well as in both mature female and male <i>second-year</i> (but not first-year) <i>B. beebei</i>, we documented an increase in two metrics of reproductive effort (size-adjusted gonad mass and electric signal amplitude) and a concomitant reduction in somatic condition (size-adjusted somatic mass) – all in response to proximity to the end of the common breeding season, when RRV approximates zero. In mature <i>first-year</i> <i>B. beebei</i>, we documented neither an increase in reproductive effort nor a decline in somatic condition, implying an alternative strategy of reproductive restraint. Our findings support Kirkwood's disposable soma theory, which posits that death by reproductive exhaustion can be delayed if terminal investment is replaced by reproductive restraint, allowing individuals to survive and breed in a subsequent season. Deferral of the terminal investment response in annual species, and the origin of a gonadal regression-regeneration sequence, may open pathways for rapid evolutionary transitions to multiseasonal iteroparity. Excepting the age (year-group) dependency of terminal investment in <i>B. beebei</i>, we were unable to identify intrinsic cues or extrinsic environmental cues for the terminal investment response in <i>Brachyhypopomus</i>.</p>
Climate overrides the effects of land use on the functional composition and diversity of mediterranean reptile assemblages.
<p>Aim: To test the hypothesis that spatial variations in climate and land use explain the distribution and diversity of reptiles' ecological traits in a biodiversity hotspot of the Mediterranean basin.</p> <p>Location: French Mediterranean region</p> <p>Taxon: Reptiles (25 species)</p> <p>Methods: We defined 288 species assemblages from 27858 opportunistic occurrence records within 10 x 10 km square grid cells. Using a RLQ analysis, we investigated the distribution of nine ecological traits describing reptiles' reproductive, dietary and behavioural strategies along environmental gradients formed by 10 climatic, topographic and land-use descriptors. After homogenizing survey effort through rarefaction, we used generalized additive models to assess variations in species richness and several measures of functional diversity and composition along these gradients. </p> <p>Results: Although ecological traits were not structured by environmental gradients at a species level, species richness and all measures of functional diversity varied non-linearly with climate, elevation and secondarily land use. Species richness and body size peaked at intermediate altitudes, indicating a climatic transition zone between Mediterranean and medio-european herpetofaunas. Conversely, functional diversity increased from Mediterranean plains, dominated by urbanization and agriculture, to higher elevations. These changes were associated with shifts towards less productive, more diurnal and more forest-related species.</p> <p>Main conclusions: Species-scale patterns are insufficient to assess regional variations in ecological traits in space. Our results support the hypothesis that climatic limitations in species' distributions, rather than environmental filtering, explain the taxonomic and ecological diversity of reptiles at a regional scale. Although secondary to climate, land abandonment has a strong structuring effect which may contribute to homogenize the composition of reptile assemblages.</p>
