Figure 3 in The first genomic resource for the 'near threatened' Neotropical otter Lontra longicaudis (Carnivora: Mustelidae): mitochondrial genome characterisation and insights into phylomitogenomic relationships in the family Mustelidae
Figure 3. An analysis of selective pressure in the protein coding genes (PCGs) of Lontra longicaudis indicates that the Ka/Ks value can show whether a gene is undergoing selection, and based on the magnitude of the value, what type of selection is taking place. Ka/Ks values <1 indicate purifying selection, whereas values equal to 1 indicate neutral selection. The Ka/Ks ratios (vertical axis) were calculated for each of the 13 PCGs (horizontal axis) by performing pairwise comparisons with L. lutra. Photo credit: John Tomsett.

Figure 2. Codon usage analysis of PCGs in the mitochondrial genome of Lontra longicaudis. All 20 amino acids [adenine (A), cysteine (C), aspartic acid (D), glutamic acid (E), phenylalanine (F), glycine (G), histidine (H), isoleucine (I), lysine (K), leucine (L), methionine (M), asparagine (N), proline (P), glutamine (Q), arginine (R), serine (S), threonine (T), valine (V), tryptophan (W), tyrosine (Y)] are listed by their one-letter abbreviations along the horizontal axis. Each amino acid comprises several codons that are listed and colour coded below their respective amino acid. The length of the coloured regions indicates the frequency of the respective codon within that amino acid. The vertical axis represents the RSCU values for the amino acids.

Threatened and endangered bird species and critical habitats in US cities
<p>Cities have classically been viewed as biologically impoverished, homogenized, and simplified systems that harbor low value for biodiversity. However, recent work has demonstrated that cities are critical ecological systems that provide important services to humanity and biodiversity. Cities can play vital roles in conserving biodiversity as well as habitats, providing system stability, and offering direct opportunities for people to engage with nature. In a rapidly changing world with biodiversity loss at an all-time high, cities have the potential to act as sanctuaries for biodiversity conservation. Here, we propose a "cities as sanctuaries" concept, which demonstrates the importance of cities for ecology and conservation, and provide the groundwork for advancing this novel field of study.</p>
FIG. 3 in Breeding Population Dynamics of Threatened Crawfish Frogs Inform Targets for Habitat Management
FIG. 3. Correlation between tadpole survival and the instantaneous population growth rate (k) for 1,000 points drawn randomly from 1,000 simulations of stochastic population simulations of Nate's Pond with (left panel) and without (right panel) immigration included in the simulation model. The white line is a third order polynomial function fitted to the data, and the gray band represents the 95% confidence interval. The horizontal dashed line indicates a k of 1. The distributions of tadpole survival rates and k values are provided as marginal plots.
FIG. 2 in Breeding Population Dynamics of Threatened Crawfish Frogs Inform Targets for Habitat Management
FIG. 2. Percent change in the instantaneous population growth rate (k) in response to a percent change in female Crawfish Frog tadpole, juvenile, or adult survival rates for a population located in southwest Indiana, USA, between 2009–2013. Percent change in each vital rate represents the general range of that vital rate observed in this study. Change was estimated by varying the focal rate while holding all other rates constant.
FIG. 1 in Breeding Population Dynamics of Threatened Crawfish Frogs Inform Targets for Habitat Management
FIG. 1. (A) Post-birth, females-only, stage matrix model of Crawfish Frogs that accommodates age and state-specific transition probabilities and the ''temporary emigration'' of individuals that skip breeding or breed at other sites. (B) Projection matrix of the model used to estimate elasticities and sensitivities of vital rates. Parameters in the matrix model: embryonic survival (Se), tadpole survival (St), metamorph and juvenile survival (Sj), adult survival following the first breeding event (Sa1), adult survival following two or more breeding events (Sa2), probability that a one-year-old juvenile matures at age 2 (p), probability that a two-year-old juvenile matures at age 3 (q), the probability that a mature individual emigrates to become a non-breeding individual (c22), probability that a non-breeding individual remains a non-breeding individual (c'), and clutch size multiplied by 0.5 to represent half of all eggs developing into females (C). We assumed that all individuals mature by age 4. Individuals that emigrate to become a nonbreeding individual may either skip reproduction or breed at another site.
Rock pools as a source of environmental DNA for the detection of the threatened Pilbara olive python (Liasis olivaceus barroni)
<p>Environmental DNA (eDNA) research is transforming biomonitoring at a global scale, but applicability to reptiles has been restricted because of their presumed low shedding rate. Consequently, eDNA may have considerable limitations as a biomonitoring tool in Australia where 40% of the terrestrial vertebrates are reptiles. However, there is a need to evaluate if method improvements such as targeting certain substrates, improves the ability to detect reptile eDNA. The Pilbara olive python (<em>Liasis olivaceus barroni</em>) is an uncommon and elusive Australian top predator with a high conservation priority. Like many other snake species, Pilbara olive pythons are challenging to monitor with traditional survey methods, therefore exploring an eDNA-based approach is highly relevant. The pythons are known to occasionally reside in rock pools. Thus, development of a reliable eDNA-based approach to detect the pythons in water would provide a needed alternative method. Here we use a previously developed metabarcoding assay targeting reptiles, to sequence a total of 228 water samples collected from 40 rock pools from six broad locations across the Pilbara region of Western Australia, and we confirm the presence of Pilbara olive python eDNA in 37 samples from 12 of those pools at three of the six broad sampling locations. Other vertebrate taxa, including other reptiles, amphibians, mammals and birds were also detected. Our documented ability to detect Pilbara olive python eDNA from rock pool water samples represents an important step towards eDNA-based precision monitoring of this species.</p>
