Background The nationally determined contribution（NDC） presented by Argentina within the framework of the Paris Agreement is aligned with the decisions made in the context of the United Nations Framework Conven-tion on Climate Change（UNFCCC） on the reduction of emissions derived from deforestation and forest degradation, as well as forest carbon conservation（REDD+）. In addition, climate change constitutes one of the greatest threats to forest biodiversity and ecosystem services. However, the soil organic carbon（SOC） stocks of native forests have not been incorporated into the Forest Reference Emission Levels calculations and for conservation planning under cli-mate variability due to a lack of information. The objectives of this study were:（i） to model SOC stocks to 30 cm of native forests at a national scale using climatic, topographic and vegetation as predictor variables, and（ii） to relate SOC stocks with spatial–temporal remotely sensed indices to determine biodiversity conservation concerns due to threats from high inter-annual climate *** We used 1040 forest soil samples（0–30 cm） to generate spatially explicit estimates of SOC native forests in Argentina at a spatial resolution of approximately 200 m. We selected 52 potential predictive environmental covari-ates, which represent key factors for the spatial distribution of SOC. All covariate maps were uploaded to the Google Earth Engine cloud-based computing platform for subsequent modelling. To determine the biodiversity threats from high inter-annual climate variability, we employed the spatial–temporal satellite-derived indices based on Enhanced Vegetation Index（EVI） and land surface temperature（LST） images from Landsat *** SOC model（0–30 cm depth） prediction accounted for 69% of the variation of this soil property across the whole native forest coverage in Argentina. Total mean SOC stock reached 2.81 Pg C（2.71–2.84 Pg C with a probability of 90%） for a total area of 460,790 km2,

Aggressive mimicry occurs when an organism resembles some aspect of another organism (the model) in order to obtain prey through its deceptive resemblance. This may function either through the overt response of the receiver or through the lack of response of the receiver. Reviewing selected examples, I discuss some of the difficulties in ascribing a model for the mimic. I also discuss how a single animal can have multiple ploys in its armoury of deceptive signals, thus belonging within two or more categories of deceptive signalling. In addition to aggressive mimicry, these may include crypsis or camouflage, masquerade (mimicry of inanimate objects), and Batesian or protective mimicry. Each of these examples of deception has multiple evolutionary pathways, and some deceptive signals may be more costly to receivers than others, but no single organism is subject to a single selection pressure, leading to the reality that many evolutionary pathways contribute to the diversity we see around us. New technologies are opening new channels of investigation into deceptive signaling in many different sensory modalities, and this is reflected in the recent increase in studies investigating the structure and function of deceptive signals. In turn, these studies are beginning to expose the fascinating complexity of deceptive signaling systems, allowing us to discover the myriad, non-mutually exclusive, solutions that can be selected for to obtain prey.

It seems intuitively sensible that an understanding of the behavioral characteristics of animals, such as their home ranges, diets, mating systems, and dispersal mechanisms, may be useful to inform conservation efforts in determining, for example, suitable reintroduction areas,or the design of dispersal corridors. Behavioral work can also determine the importance of a species within its habitat, for example as a seed disperser, and can highlight which extant species may play fundamental ecological roles, especially in areas where recent extinctions have led to drastic changes in biological composition (e.g., Young et al., 2012). So why is it that these two disciplines rarely merge, despite now being the discipline of Conservation Behavior in its own right? This disconnect and where it occurs has been identified by Palestis(2014), and multiple times by Caro (e.g., 1999,2007), whom contribute to this special column. Both Palestis (2014) and Caro (2007) suggest that behavioral ecologists have been “slow to link with conservation biologists” (Palestis, 2014).

The unique alpine-living kea parrotNestor notabilishas been the focus of numerous cognitive studies, but its communication system has so far been largely neglected. We examined 2,884 calls recorded in New Zealand’s Southern Alps. Based on audio and visual spectrographic differences, these calls were categorised into seven distinct call types: the non-oscillating ‘screech’ contact call and ‘mew’; and the oscillating ‘trill’, ‘chatter’, ‘warble’ and ‘whistle’; and a hybrid ‘screech-trill’. Most of these calls contained aspects that were individually unique, in addition to potentially encoding for an individual’s sex and age. Additionally, for each recording, the sender’s previous and next calls were noted, as well as any response given by conspecifics. We found that the previous and next calls made by the sender were most often of the same type, and that the next most likely preceding and/or following call type was the screech call, a contact call which sounds like the ‘kee-ah’ from which the bird’s name derives. As a social bird capable of covering large distances over visually obstructive terrain, long distance contact calls may be of considerable importance for social cohesion. Contact calls allow kea to locate conspecifics and congregate in temporary groups for social activities. The most likely response to any given call was a screech, usually followed by the same type of call as the initial call made by the sender, although responses differed depending on the age of the caller. The exception was the warble, the kea’s play call, to which the most likely response was another warble. Being the most common call type, as well as the default response to another call, it appears that the ‘contagious’ screech contact call plays a central role in kea vocal communication and social cohesion.

To understand communication, the interests of the sender and the receiver/s of signals should be considered separately. When our goal is to understand the adaptive significance of specific responses to specific signals by the receiver, questions about signal information are useful. However, when our goal is to understand the adaptive significance to the sender of generating a signal, it may be better to envisage the receiver’s response to signals as part of the sender’s extended phenotype. By making signals, a sender interfaces with the receiver’s model of the world and indirectly manipulates its behaviour. This is especially clear in cases of mimicry, where animals use deceptive signals that indirectly manipulate the behaviour of receivers. Many animals adopt Batesian mimicry to deceive their predators, or aggressive mimicry to deceive their prey. We review examples from the literature on spiders to illustrate how these phenomena, traditionally thought of as distinct, can become entangled in a web of lies.
