During late ebb and early flood tides, while off-spring were nest dependent, parents. Physico-chemical variables of the tidal cycle were associated with the parental behavior of B. Parental behavior of the substrate-brooding cichlid, Biotodoma cupido, was studied in a small creek entering the lower Essequibo River, Guyana, where the freshwaters are affected by semi-diurnal tides. Their use would especially benefit the study of the biogeographic patterns of subterranean fauna and the impact of past and future climate change on subterranean ecosystems. A more widespread adoption of these statistical techniques in subterranean biology is highly attractive and has great potential in broadening our knowledge on a variety of ecological topics, especially in the fields of climate change and biodiversity conservation. In parallel, we discuss the potential use of different large scale surface variables to represent the subterranean condition. We focus on the typical bias in spatial datasets of cave-dwelling species, and provide advice for selecting the model calibration area. The aim of this forum is to explore the caveats that need to be made when generalizing these statistical techniques to caves and other subterranean habitats. The reason for this is possibly related to a number of peculiarities of subterranean systems, which pose important limits, but also opportunities, for these correlative models. Conversely, the use of these statistical methods to study the potential distribution of subterranean organisms has lagged behind, relative to their above-ground (epigean). Over the last two decades there has been an exponential increase in the use of correlative species distribution models (SDMs) to address a variety of topics in ecology, biogeography, evolution, and conservation biology. identify priorities for research and conservation in such environments. explore the link between avian species/communities and factors operating at the field, landscape and management level propose birds as models to address biodiversity conservation issues in these systems In addition, large areas of biodiversity-rich traditional systems have disappeared because of land abandonment.įor all those reasons, we believe that a better understanding of the ecological relationships in these farming systems is urgently needed to address conservation issues as well as sustainable management. However, most of such crops and grasslands are nowadays managed as intensive production systems and have lost a large part of their associated biodiversity. hay-meadows and pastures) were traditionally managed as low-intensity, semi-natural farming systems, a nd some of them are still recognised as High Nature Value farmlands. vineyards, orchards, etc.) and anthropogenic grasslands (e.g.
