title: Data from: Demographic response to patch destruction in a spatially structured amphibian population

description: 1. Economic activities such as logging and mineral extraction can result
 in the creation of new anthropogenic habitats that host specific
 biodiversity, including protected species. However, the legislation in
 many Western European countries requires the rehabilitation of ‘damaged’
 areas following logging and mining operations, which can eliminate these
 early successional habitats. Conservation managers face a dilemma in these
 situations, but often lack knowledge about the impacts of environmental
 rehabilitation on the population dynamics of pioneer species and so are
 unable to take this into account in their actions. 2. We investigated the
 demography of a spatially structured population of an endangered amphibian
 (Bombina variegata) that uses waterbodies created by logging activities as
 breeding sites. Using capture–recapture (CR) data collected during a
 9-year study period, we examined how the destruction of breeding patches
 due to environmental rehabilitation affected adult survival and the
 long-term population growth rate. For this purpose, we used recently
 developed capture-recapture multievent models to estimate survival and
 dispersal rates in the spatially structured population. We then used these
 estimates to simulate population trajectories and viability depending on
 differing frequency of breeding patch destruction. 3. The multievent
 models revealed that dispersal not resulting from patch loss was
 relatively high and was sex-biased. They also revealed that patch
 destruction had a negative impact on adult survival. Moreover, simulations
 showed that the increase of patch destruction frequency had a strong
 negative influence on the population growth rate, even when the number of
 patch remained constant over time. This impact was intensified if female
 fecundity was also affected. 4. Synthesis and applications. Our study
 quantified for the first time the detrimental effect of habitat
 rehabilitation on the population dynamics of an endangered, pioneer
 species. Yet our study also found that this deleterious impact of patch
 destruction could be reduced by certain management practices, as avoiding
 the systematic rehabilitation of the breeding patches and compensating for
 patch destruction by creating substitute breeding patches.
description: Capture-recapture
 dataData description The
 capture-recapture data used in Cayuela et al. (2018, J. Appl. Ecol) were
 collected in a spatially structured population of Bombina variegata in
 France, over an 9-years period (2000-2008). Several capture sessions were
 performed per year (detailed in Supplementary material S1 of the paper).
 The individuals are in raws and the capture occasion on column (labelled
 “H:”). The column “S:” specifies the end of the capture history. The
 column labeled “$COV:sex” is the sex coded as a group effect (1 = male, 2
 = female). The capture-recapture histories are coded with the following
 events. For an individual captured at t and t–1, we attributed a code of 1
 if it had not dispersed and occupied a patch destroyed at t+1 or a code of
 4 if the patch was still available; we attributed a code of 2 if an
 individual had dispersed and occupied a patch destroyed at t+1 or a code
 of 5 if the patch was still available. For an individual not captured at
 t–1 but captured at t, a code of 3 or 6 was attributed respectively if it
 occurred in a patch destroyed at t+1 or not. An individual was coded 0 if
 it was not captured at t. The txt file is compatible with E-SURGE program.
