“…At the finest spatial scale considered, just one microhabitat type explained a small amount of variation in species composition. Availability of potential tadpole food items has been shown to vary among microhabitats in streams (based on another study conducted at streams at the same site [ 65 ]) and food items provide different nutrients for tadpoles, influencing their growth and metamorphosis (e.g. [ 66 – 67 ]).…”

“…Our detailed classification of tadpole microhabitats may have precluded the association of a significant amount of changes in species composition to a single microhabitat type. Besides, microhabitats used by tadpoles greatly overlap in availability of food types [ 65 ]. Thus, only a broad alteration of stream microstructure might be expected to reduce the set of available microhabitats in a way to cause noticeable effects on anuran species composition via decreased resource availability.…”

Amphibians are sensitive to anthropogenic habitat alterations but also respond to natural drivers of assemblage composition at many levels. Additionally, they are usually hard to detect in field inventories. We used a multiscale approach, from microhabitat to the landscape levels, to try to understand the effects of natural changes, and try to distinguish them from the effects of landscape level anthropogenic changes, on dynamic and diverse anuran assemblages, taking imperfect detection into account. We conducted thorough field inventories in 16 streams at Serra do Cipó, in the southern portion of Espinhaço Mountain Range, southeastern Brazil, during two time periods separated by 16 years. We compared species richness and diversity between periods, sampling both tadpoles and adult frogs. We quantified tadpole microhabitat availability, alterations in immediate riparian vegetation, and changes in classes of land cover within buffers around streams (adult habitats) to test for their effects on species composition. We also tested for effects of human occupancy around streams on nestedness and turnover components of species diversity. Microhabitats and riparian vegetation explained some of the changes in species composition (or detection) between time periods. Nestedness seemed to be influenced by the stability of the landscape. Detectabilities were too low to support robust occupancy estimates for most species. Natural changes in local habitats occupied by anurans in montane meadows are likely to influence species distribution. Some species with robust estimates experienced change in their occupancy over the studied 16-year interval, although no anthropogenic causes could be directly associated with such changes. The low detectability of most species, even with thorough sampling effort, makes it very hard to detect amphibian declines and possibly tell them apart from natural population fluctuations. New techniques are needed that improve species detectability in such diverse tropical habitats.

“…The scientific literature includes a plethora of terms to denote ISD. These include morphotypes (Chavarie et al., 2013 ; Collyer et al., 2015 ; Lessios & Weinberg, 1994 ); ecotypes (Arostegui et al., 2018 ; Cruz‐Font et al, 2019 ; Gregor, 1944 ) species pairs (Taylor, 1999 ); ecomorphotypes (Baker et al., 1998 ; Kloh et al., 2019 ; Segura‐Trujillo et al., 2018 ); ecophenotypes (Proćków et al., 2018 ; Schönborn & Peschke, 1988 ; Sorensen & Lindberg, 1991 ); polymorphisms (Jamie & Meier, 2020 ; Skúlason et al., 2019 ; Skúlason & Smith, 1995 ); and life histories (Stearns, 1989 ; Winemiller & Rose, 1992 ). Several of these terms have common roots and are often used interchangeably or in combination (e.g., Baker et al., 1998 ; Brannon et al., 2004 ; Chavarie et al., 2013 ; Palacios et al., 2012 ; Wood et al., 2008 ).…”

“…Tadpoles may reach high abundances (Gibbons et al 2006, Pinero-Rodriguez et al 2020 and have an important ecological role, contributing to nutrient cycling, altering the trophic web, and even causing bioturbation by modifying the distribution of sediments (Costa and Vonesh 2013, Cortés-Gómez et al 2015, Kloh et al 2019. They can potentially decrease food resources, including submerged plant biomass (Arribas et al 2014).…”

Herbivory by spadefoot toad tadpoles and reduced water level affect submerged plants in temporary ponds

In temporary ponds, submerged plants have adapted to recurrent periods of drought. These ponds often lack the impact of large herbivores but can harbor large numbers of herbivorous tadpoles. Tadpoles of the Iberian spadefoot toad (Pelobates cultripes) may reach large body size and consume large quantities of macrophytes during their long larval period, which is shortened with risk of pond drying. We conducted a mesocosm experiment to analyze the interplay between hydroperiod and impact of herbivorous tadpoles on the abundance and life history of 3 species of submerged plants common to temporary ponds. We observed differences in growth among plant species resulting in lags in timing of maximum cover, probably related to interspecific competitive interactions. Some plants responded to pond drying with a remarkable increase in the production of flowers. Tadpoles greatly reduced the plant cover, although their impact varied across plant species. Differential plant consumption by these large tadpoles can substantially modify the internal structure and complexity of temporary ponds, and tadpoles can also interfere with plant responses to shortened hydroperiod.
