“…Engystomops petersi (Wasserssug & Heyer, 1988; this work) and E. pustulosus (Wasserssug & Heyer, 1988) share two pair of postnarial papillae (one pair in other species), likely a synapomorphy for the Edentulus clade (Ron et al, 2006). Although this clade presents interesting cytogenetic (Targueta et al, 2010, 2021), acoustic (Boul et al, 2007; Guerra & Ron, 2008), and genetic variability (Funk et al, 2007) even among populations of the same species, others set of characters are more homogeneous, supporting the existence of the clade, such as the absence of teeth in adults (Cannatella et al, 1998; Ron et al, 2006) and the presence of axial fibers in the tails of spermatozoa (Santos et al, 2016). The presence of two pair of postnarial papillae is a rare character in Leiuperinae, besides Engystomops , it appears independently in Pleurodema nebulosum (Wasserssug & Heyer, 1988), Edalorhina perezi (Nascimento et al, 2021) and in members of Physalaemus biligonigerus species group (Nomura et al, 2003; Perotti & Céspedez, 1999; Sandoval, 2002).…”

The highly differentiated anuran larvae make them an interesting and complementary source of information to understand anuran evolution. Among neotropical foam-nesting frogs, the available information on tadpole morphology for the subfamily Leiuperinae remains largely incomplete and variably reported among genera; in the monophyletic genus Engystomops it is still incipient. Herein, we summarize available information on larval morphology for five of the nine known species of Engystomops, three of them for the first time, reporting external morphology, buccopharyngeal cavity, and skeleton. The tadpoles of the genus have an overall generalized morphology and many traits are conserved across species.Nevertheless, many characters are systematically informative and some are diagnostic for some species, as the paravertebral gland in Engystomops petersi and the dorsally directed spiracle in Engystomops puyango. Other characters provide support for some subclades within the genus. Moreover, some traits, such as the direction of the vent tube, supports the close relationship between Engystomops and Physalaemus, whereas other support the existence of these two as distinct genera, such as the overall shape of the lateral ridge papillae and the presence of a processus pseudopterygoideus.

“…Salinized soil is widely distributed globally, covering 424 million ha of topsoil (0-30 cm) and 833 million ha of subsoil (30-100 cm) [41], with an annual growth rate of 1.0 × 10 6 -1.5 × 10 6 hm 2 [42,43]. The character of saline soil includes a heavy texture, poor permeability, high salt content, lack of nutrients, and low microbial activity, which seriously affects crop growth and ecosystem functions [44,45]. However, the saline soil area is flat, which is suitable for mechanical cultivation and has great fertility potential.…”

Straw returning is an important measurement to determine the utilization of straw resources. Understanding the decomposition process and nutrient release process of straw is of great significance to the efficient utilization of straw resources and the sustainable development of the agricultural economy. In this study, the literature published in the CNKI and WOS from 2002 to 2022 was used as the data pool, and a keyword co-occurrence network map was drawn with the CiteSpace (6.2.R4) software. Visual analyses were based on the straw returning literature (1998 articles) and straw decomposition agent literature (125 articles), and the decomposition and nutrient release of straw under the action of a decomposition agent were analyzed using a straw decomposition characterization experiment. In general, returning straw can effectively improve soil fertility conditions and provide nutrients for crop growth, and the use of a straw decomposition agent can further improve soil conditions and increase crop yield. The straw decomposition characterization experiment further showed that Pseudomonas could effectively increase the decomposition rate and increase the nutrient release rate of straw. According to the above results, determining how to improve the utilization efficiency of straw resources via decomposable bacteriological agents according to local conditions will become a research hotspot in the future.
